Pontiac GTO, 1967

Pontiac GTO, 1967

The Pontiac GTO was an automobile built by Pontiac from 1964 to 1974, and by General Motors Holden in Australia from 2003 to 2006. It is often considered the first true muscle car. From 1964 until 1973.5, it was closely related to the Pontiac Tempest, but for its final year it was based on the Pontiac Ventura. The 21st century GTO is essentially a left hand drive Holden Monaro, itself a coupe variant of the Holden Commodore.

Origins
The GTO was the brainchild of Pontiac engineer Russell Gee, an engine specialist, and Pontiac chief engineer John De Lorean. Shane Wiser was the first to think of the idea of the GTO. In early 1963, General Motors management issued an edict banning divisions from involvement in auto racing. At the time, Pontiac's advertising and marketing approach was heavily based on performance, and racing was an important component of that strategy. Jim Wangers proposed a way to retain the performance image that the division had cultivated with a new focus on street performance. It involved transforming the upcoming redesigned Tempest (which was set to revert to a conventional front-engine, front transmission, rear-wheel drive configuration) into a "Super Tempest" with the larger 389 in³ (6.5 L) Pontiac V8 engine from the full-sized Pontiac Catalina and Bonneville in place of the standard 326 in³ (5.3 L) Tempest V8. By promoting the big-engine Tempest as a special high-performance model, they could appeal to the speed-minded youth market (which had also been recognized by Ford Motor Company's Lee Iacocca, who was at that time preparing the Ford Mustang).

The name, which was DeLorean's idea, was inspired by the Ferrari 250 GTO, the highly successful race car. It is an acronym for Gran Turismo Omologato, Italian for homologated for racing in the GT class. The name drew protest from purists, who considered it close to sacrilege.

The GTO was technically a violation of GM policy limiting the A-body intermediate line to a maximum engine displacement of 330 in³ (5.4 L). Since the GTO was an option package and not standard equipment, it could be considered to fall into a loophole in the policy. Pontiac General Manager Elliot "Pete" Estes approved the new model, although sales manager Frank Bridge, who did not believe it would find a market, insisted on limiting initial production to no more than 5,000 cars. Had the model been a failure, Estes likely would have been reprimanded. As it turned out, it was a great success.

First generation

1964
The first Pontiac GTO was an option package for the Pontiac LeMans, available with the two-door sedan, hardtop coupe, and convertible body styles. For US$ 296, it included the 389 in³ V8 (rated at 325 hp (242 kW) at 4800 rpm) with a single Carter AFB four-barrel carburetor and dual exhaust, chromed valve covers and air cleaner, 7 blade clutch fan, a floor-shifted three-speed manual transmission with Hurst shifter, stiffer springs, larger diameter front sway bar, wider wheels with 7.50 x 14 redline tires, hood scoops, and GTO badges. Optional equipment included a four-speed manual transmission, two-speed automatic transmission, a more powerful "Tri-Power" carburation rated at 348 hp (260 kW), metallic drum brake linings, limited slip differential, heavy-duty cooling, ride and handling package, and the usual array of power and convenience accessories. With every available option, the GTO cost about US$ 4,500 and weighed around 3,500 pounds (1,600 kg).

Most contemporary road tests used the more powerful Tri-Power engine and four-speed. Car Life clocked a GTO so equipped at 0-60 miles per hour (0-97 km/h) in 6.6 seconds, through the standing quarter mile in 14.8 seconds with a top speed of 99 miles per hour (158 km/h). Like most testers, they criticized the slow steering, particularly without power steering, and inadequate drum brakes, which were identical to those of the normal Tempest. Car and Driver incited controversy when it printed that a GTO that had supposedly been tuned with the "Bobcat" kit offered by Royal Pontiac of Royal Oak, Michigan, was clocked at a quarter mile time of 12.8 seconds and a top speed of 112 mph (179 km/h) on racing slicks. Later reports strongly suggest that the Car and Driver GTOs were equipped with a 421 in³ (6.9 L) engine that was optional in full-sized Pontiacs. Since the two engines were difficult to distinguish externally, the subterfuge was not immediately obvious. Frank Bridge's sales forecast proved inaccurate: the GTO package had sold 10,000 units before the beginning of the 1964 calendar year, and total sales were 32,450.

Bobcat
Throughout the 1960s, Royal Pontiac, a Pontiac car dealer in Royal Oak, Michigan, offered a special tune-up package for Pontiac 389 engines. Many were fitted to GTOs, and the components and instructions could be purchased by mail as well as installed by the dealer. The name "Bobcat" came from the improvised badges created for the modified cars, combining letters from the "Bonneville" and "Catalina" nameplates. Many of the Pontiacs made available for magazine testing were equipped with the Bobcat kit. The GTO Bobcat accelerated 0-60 in 4.6 seconds (this 0-60 time is now equalled by the factory 2005-06 GTO with automatic transmission and no modification).

The precise components of the kit varied but generally included pieces to modify the spark advance of the distributor, limiting spark advance to 34-36° at no more than 3,000 rpm (advancing the timing at high rpm for increased power), a thinner head gasket to raise compression to about 11.23:1, a gasket to block the heat riser of the carburetor (keeping it cooler), larger carburetor jets, high-capacity oil pump, and fiberglass shims with lock nuts to hold the hydraulic valve lifters at their maximum point of adjustment, allowing the engine to rev higher without "floating" the valves. Properly installed, the kit could add between 30 and 50 horsepower (20-40 kW), although it required high-octane superpremium gasoline of over 100 octane to avoid spark knock with the higher compression and advanced timing.

1965
The Tempest line, including the GTO, was restyled for the 1965 model year, adding 3.1 inches (7.9 cm) to the overall length while retaining the same wheelbase and interior dimensions. It sported Pontiac's characteristic vertically stacked quad headlights. Overall weight increased about 100 pounds (45 kg). Brake lining area increased nearly 15%. The dashboard design was improved, and an optional rally gauge cluster added a more legible tachometer and oil pressure gauge.

The 389 engine had revised cylinder heads with re-cored intake passages, improving breathing. Rated power increased to 335 hp (250 kW) @ 5,000 rpm for the base 4—barrel engine; the Tri-Power was rated 360 hp ((268 kW) @ 5,200 rpm. The Tri-Power engine had slightly less torque than the base engine, 424 ft·lbf (574 N·m) @ 3,600 rpm versus 431 ft·lbf (584 N·m) @ 3,200 rpm. Transmission and axle ratio choices remained the same.

The restyled GTO had a new simulated hood scoop. A rare, dealer-installed option was a metal underhood pan and gaskets that allowed the scoop to be opened, transforming a cosmetic device into a functional cold air intake. The scoop was low enough that its effectiveness was questionable (it was unlikely to pick up anything but boundary layer air), but it at least admitted cooler, denser air, and allowed more of the engine's formidable roar to escape.

Car Life tested a 1965 GTO with Tri-Power and what they considered the most desirable options (close-ratio four-speed manual transmission, power steering, metallic brakes, rally wheels, 4.11 limited-slip differential, and Rally Gauge Cluster), with a total sticker price of US$3,643.79. With two testers and equipment aboard, they recorded 0-60 miles per hour (0-97 km/h) in 5.8 seconds, the standing quarter mile in 14.5 seconds with a trap speed of 100 miles per hour (160 km/h), and an observed top speed of 114 miles per hour (182.4 km/h) at the engine's 6,000 rpm redline. Even Motor Trend's four-barrel test car, a heavier convertible handicapped by the two-speed automatic transmission and the lack of a limited slip differential, ran 0-60 mph in 7 seconds and through the quarter mile in 16.1 seconds at 89 miles per hour (142.4 km/h).

Pontiac's intermediate line was restyled again for 1966,
gaining more curvaceous styling with kicked-up rear fender lines for a "Coke-bottle" look, and a slightly "tunneled" backlight. Overall length grew only fractionally, to 206.4 inches (524 cm), still on a 115 inch (292 cm) wheelbase, while width expanded to 74.4 inches (189 cm). Rear track increased one inch (2.5 cm). Overall weight remained about the same. The GTO became a separate model series, rather than an option package, with unique grille and tail lights, available as a pillared sports coupe, a hardtop sans pillars, or a convertible. Also an automotive industry first, plastic front grilles replaced the pot metal and aluminum versions seen on earlier years. New Strato bucket seats were introduced with higher and thinner seat backs and contoured cushions for added comfort and adjustable headrests were introduced as a new option. The instrument panel was redesigned and more integrated than in previous years with the ignition switch moved from the far left of the dash to the right of the steering wheel. Four pod instruments continued, and the GTO's dash was highlighted by walnut veneer trim. The 1966 model year is viewed by many as the most iconic of all GTOs because of its independent model status and because it was the last year Pontiac offered the 389 Tri Power engine configuration.

Engine choices remained the same as the previous year. A new rare engine option was offered: the XS engine option consisted of a factory Ram Air set up with a new 744 high lift cam. Approximately 35 factory installed Ram Air packages are believed to have been built, though 300 dealership installed Ram Air packages are estimated to have been ordered. On paper, the package was said to produce the same 360 hp as the non-Ram Air, Tri Power car, though these figures are believed to have been grossly underestimated in order to get past GM mandates.

Sales increased to 96,946, the highest production figure for all GTO years. Although Pontiac had strenuously promoted the GTO in advertising as the "GTO Tiger," it had become known in the youth market as the "Goat." Pontiac management attempted to make use of the new nickname in advertising but were vetoed by upper management, which was dismayed by its irreverent tone.

1967
Styling remained essentially unchanged for 1967, but the GTO saw several significant mechanical changes.

A corporate policy decision banned multiple carburetors for all cars except the Chevrolet Corvette, so the Tri-Power engine was cancelled and replaced with new quadrajet four-barrel carburetor. Chevrolet was able to keep the tri-power set up to help with their image; the GTO was really becoming a serious competition problem for them. To compensate, the 389 engine received a slightly wider cylinder bore (4.12 inches, 104.7 mm) for a total displacement of 400 in³ (6.6 L). Torque increased slightly, from 431 to 441 ft-lbf (584 to 598 N·m) for the base engine, from 424 to 438 ft-lbf (575 to 594 N·m) for the optional engine but power remained the same. Testers found little performance difference, although the distinctive sound and fury of the Tri-Power was missed.

Two new engines were offered. The first was an economy engine, also 400 in³ but with a two-barrel carburetor, 8.6:1 compression, and a rating of 265 hp (198 kW) and 397 ft-lbf (538 N·m) of torque.  The package, which included a functional hood scoop (much like the previous dealer-installed set-up), featured stiffer valve springs and a longer-duration camshaft. Rated power and torque were unchanged, although the engine was certainly stronger than that of the standard 360 hp (268 kW) GTO. It was available only with 3.90:1 or 4.33:1 differential gearing, and its "hotter" camshaft left it with a notably lumpier idle and less cooperative part-throttle response.

Emission controls, including an air injector system, were fitted in GTOs sold in California only.

The two-speed automatic was replaced with the three-speed Turbo-Hydramatic TH400, which was available with any engine. When the Strato bucket seats and console were ordered, the TH was further enhanced by the use of Hurst's Dual-Gate shifter, which permitted automatic shifting in "Drive' or manual selection through the gears. It was generally considered an equal match for the four-speed in most performance aspects. Meanwhile, the Tempest's inadequate drum brakes could be replaced by optional disc brakes on the front wheels (for US$104.79, including power boost), a vast improvement in both braking performance and fade resistance.

Pontiac Firebird, 1967

Pontiac Firebird, 1967

The first-generation Firebirds had a characteristic "coke-bottle" styling. Unlike the Camaro, its bumpers were integrated into the design of the front end and its rear "slit" taillights were inspired by the Pontiac GTO. Both a two-door hardtop and a convertible were offered through the 1970 model year (the next generation, dropping the convertible, being announced as 1970 1/2 models).

The base model had a 230 in³ (3.8 L) OHC six-cylinder, single-barrel carburetor motor developing 165 hp (123 kW). The next model, the Sprint, had a four-barrel carburetor, developing 215 hp (160 kW). Most buyers opted for the V8s: the 326 in³ (5.3 L) two-barrel 250 hp (186 kW, the 'H.O.' (High Output) engine of the same size but with a four-barrel carburetor 285 hp (213 kW), or the 400 in³ (6.6 L) from the GTO 325 hp (242 kW). A Ram Air option was available, with functional hood scoops, higher flow heads with stronger valve springs and a different camshaft.
Power for the Ram/Air package was the same as the conventional 400HO, but peaked at a higher RPM. The 230 in³ (3.8 L) engines were replaced by 250 in³ (4.1 L) ones, developing 175 hp (130 kW) single barrel, and 215 hp (160 kW) four-barrel. An H.O. version of the 400 in³ (6.6 L) was offered from 1968, with a revised cam, and developed 330 hp (246 kW), while power output on the other engines increased marginally. In 1969, a $725 optional handling package called the Trans Am Performance and Appearance Package was introduced, named after the Trans-Am Series. As the name was used without permission, the SCCA threatened to sue, but GM settled the deal by paying $5 to the SCCA for every car sold. Of these first Trans Ams, 689 hardtops and eight convertibles were made. There was an additional Ram Air IV engine option for the 400 in³ that year to complement the Ram Air II; these generated 345 and 335 hp respectively.

Despite the 1969 model year being the last of this generation, production in fact went into 1970, totalling 17 months, due to problems with the 1970s.

The first-generation Firebird could easily be told from the Camaro with its four round headlamps, while the Camaro got only two.

Pontiac Trans Am reborn

OK, not officially, but Lingenfelter Performance Engineering of Indiana has created what it thinks a modern Trans Am might have looked like had General Motors not pulled the plug on the Pontiac brand.

Called the Lingenfelter TA, the car is based on the current Chevrolet Camaro SS and takes the 1971 Trans Am as its design inspiration.

Not many of the Camaro’s panels survive the transformation intact. The front end is completely replaced, as are the rear quarter panels and all of the lights. Finishing off the exterior are 20" wheels, Nitto tyres and a Corsa exhaust system. Meanwhile, the interior is very 70s retro, and it features custom seats, centre console, door panels, carpets and a turned metal instrument panel.

Engine capacity has been increased from 6.2 litres (376 cu in) 7.5 litres (455 cu in) and, with modifications including a ported and polished cylinder head, forged aluminium pistons and a new inlet manifold, it now produces 655 bhp (488 kW / 664 PS) and 827 Nm (610 lb ft) of torque. Drive is via a six-speed manual transmission.

Cost of the V8 SS-based Lingenfelter TA is around $150,000 (about £98,000 / €118,000), including the donor car. However, if a V6 Camaro is used instead the price falls to around $85,000 (£55,000 / €67,000).

Pontiac G3

Pontiac G3, 2009

Expanding its portfolio in the rapidly growing small car segment, Pontiac announced plans to bring the sporty, five-door hatchback Pontiac G3 to U.S. showrooms early next year. When it arrives, the G3 will provide Pontiac with a total of four vehicles capable of more than 30 miles per gallon on the highway.

Successful in Canada (as the Pontiac G3 Wave) and Mexico (as a sedan model), the Pontiac G3 offers an EPA estimated 27 mpg in the city and 34 mpg on the highway while providing the best shoulder and hip room in the segment for seating five adults.

"The small car segment has literally exploded in recent months, with sales up nearly 33 percent in the first six months of 2008 alone," said Susan Docherty, vice president of Buick-Pontiac-GMC. "With its proven success in other markets, we felt the time was right to bring the Pontiac G3 into the BPG portfolio for our U.S. customers."

The 2009 Pontiac G3 will join the all-new 2009 Pontiac Vibe (32 mpg) and recently enhanced 2009 versions of the G6 sedan (33 mpg) and G5 coupe (37 mpg) in Pontiac's "Over 30" club.
"More than ever, fuel economy is an important factor in Pontiac's formula of style and performance," said Docherty. "The Vibe, G3, G5, and G6 prove that you don't have to sacrifice sporty design and responsive driving to achieve impressive fuel economy."

Generating 106 horsepower (79 kW), the Pontiac G3's 1.6L Ecotec four-cylinder engine is mated to a five-speed manual or optional four-speed automatic transmission. It will also feature an unusually rich mix of standard features for an entry-level car, including air conditioning, a CD/MP3 audio system with auxiliary input jack, fog lamps, rear spoiler, OnStar, and a host of standard safety features, including four airbags, that gain the Pontiac G3 a five-star frontal crash rating.

Interior space is optimized to comfortably seat five adults, including "theater"-style seating for rear seat passengers. The rear seats also feature a 60/40 split to offer up to 42 cubic feet of cargo space.

Pontiac GTO

Pontiac GTO 1964

The Pontiac GTO was an automobile built by Pontiac from 1964 to 1974, and by General Motors Holden in Australia from 2003 to 2006. It is often considered the first true muscle car. From 1964 until 1973.5, it was closely related to the Pontiac Tempest, but for its final year it was based on the Pontiac Ventura. The 21st century GTO is essentially a left hand drive Holden Monaro, itself a coupe variant of the Holden Commodore.

Had the model been a failure, Estes likely would have been reprimanded. As it turned out, it was a great success.

First generation
1964
The first Pontiac GTO was an option package for the Pontiac LeMans, available with the two-door sedan, hardtop coupe, and convertible body styles. For US$ 296, it included the 389 in³ V8 (rated at 325 hp (242 kW) at 4800 rpm) with a single Carter AFB four-barrel carburetor and dual exhaust, chromed valve covers and air cleaner, 7 blade clutch fan, a floor-shifted three-speed manual transmission with Hurst shifter, stiffer springs, larger diameter front sway bar, wider wheels with 7.50 x 14 redline tires, hood scoops, and GTO badges. Optional equipment included a four-speed manual transmission, two-speed automatic transmission, a more powerful "Tri-Power" carburation rated at 348 hp (260 kW), metallic drum brake linings, limited slip differential, heavy-duty cooling, ride and handling package, and the usual array of power and convenience accessories. With every available option, the GTO cost about US$ 4,500 and weighed around 3,500 pounds (1,600 kg).

Most contemporary road tests used the more powerful Tri-Power engine and four-speed. Car Life clocked a GTO so equipped at 0-60 miles per hour (0-97 km/h) in 6.6 seconds, through the standing quarter mile in 14.8 seconds with a top speed of 99 miles per hour (158 km/h). Like most testers, they criticized the slow steering, particularly without power steering, and inadequate drum brakes, which were identical to those of the normal Tempest. Car and Driver incited controversy when it printed that a GTO that had supposedly been tuned with the "Bobcat" kit offered by Royal Pontiac of Royal Oak, Michigan, was clocked at a quarter mile time of 12.8 seconds and a top speed of 112 mph (179 km/h) on racing slicks. Later reports strongly suggest that the Car and Driver GTOs were equipped with a 421 in³ (6.9 L) engine that was optional in full-sized Pontiacs. Since the two engines were difficult to distinguish externally, the subterfuge was not immediately obvious. Frank Bridge's sales forecast proved inaccurate: the GTO package had sold 10,000 units before the beginning of the 1964 calendar year, and total sales were 32,450.

Bobcat
Throughout the 1960s, Royal Pontiac, a Pontiac car dealer in Royal Oak, Michigan, offered a special tune-up package for Pontiac 389 engines. Many were fitted to GTOs, and the components and instructions could be purchased by mail as well as installed by the dealer. The name "Bobcat" came from the improvised badges created for the modified cars, combining letters from the "Bonneville" and "Catalina" nameplates. Many of the Pontiacs made available for magazine testing were equipped with the Bobcat kit. The GTO Bobcat accelerated 0-60 in 4.6 seconds (this 0-60 time is now equalled by the factory 2005-06 GTO with automatic transmission and no modification).

The precise components of the kit varied but generally included pieces to modify the spark advance of the distributor, limiting spark advance to 34-36° at no more than 3,000 rpm (advancing the timing at high rpm for increased power), a thinner head gasket to raise compression to about 11.23:1, a gasket to block the heat riser of the carburetor (keeping it cooler), larger carburetor jets, high-capacity oil pump, and fiberglass shims with lock nuts to hold the hydraulic valve lifters at their maximum point of adjustment, allowing the engine to rev higher without "floating" the valves. Properly installed, the kit could add between 30 and 50 horsepower (20-40 kW), although it required high-octane superpremium gasoline of over 100 octane to avoid spark knock with the higher compression and advanced timing.

1965
The Tempest line, including the GTO, was restyled for the 1965 model year, adding 3.1 inches (7.9 cm) to the overall length while retaining the same wheelbase and interior dimensions. It sported Pontiac's characteristic vertically stacked quad headlights. Overall weight increased about 100 pounds (45 kg). Brake lining area increased nearly 15%. The dashboard design was improved, and an optional rally gauge cluster added a more legible tachometer and oil pressure gauge.

The 389 engine had revised cylinder heads with re-cored intake passages, improving breathing. Rated power increased to 335 hp (250 kW) @ 5,000 rpm for the base 4—barrel engine; the Tri-Power was rated 360 hp ((268 kW) @ 5,200 rpm. The Tri-Power engine had slightly less torque than the base engine, 424 ft·lbf (574 N·m) @ 3,600 rpm versus 431 ft·lbf (584 N·m) @ 3,200 rpm. Transmission and axle ratio choices remained the same.

The restyled GTO had a new simulated hood scoop. A rare, dealer-installed option was a metal underhood pan and gaskets that allowed the scoop to be opened, transforming a cosmetic device into a functional cold air intake. The scoop was low enough that its effectiveness was questionable (it was unlikely to pick up anything but boundary layer air), but it at least admitted cooler, denser air, and allowed more of the engine's formidable roar to escape.

Car Life tested a 1965 GTO with Tri-Power and what they considered the most desirable options (close-ratio four-speed manual transmission, power steering, metallic brakes, rally wheels, 4.11 limited-slip differential, and Rally Gauge Cluster), with a total sticker price of US$3,643.79. With two testers and equipment aboard, they recorded 0-60 miles per hour (0-97 km/h) in 5.8 seconds, the standing quarter mile in 14.5 seconds with a trap speed of 100 miles per hour (160 km/h), and an observed top speed of 114 miles per hour (182.4 km/h) at the engine's 6,000 rpm redline. Even Motor Trend's four-barrel test car, a heavier convertible handicapped by the two-speed automatic transmission and the lack of a limited slip differential, ran 0-60 mph in 7 seconds and through the quarter mile in 16.1 seconds at 89 miles per hour (142.4 km/h).

Major criticisms of the GTO continued to center on its slow steering (ratio of 17.5:1, four turns lock-to-lock) and mediocre brakes. Car Life was satisfied with the metallic brakes on its GTO, but Motor Trend and Road Test found the standard drums with organic linings to be alarmingly inadequate in high-speed driving.

Sales of the GTO, abetted by a formidable marketing and promotional campaign that included songs and various merchandise, more than doubled to 75,342. It was already spawning many imitators, both within other GM divisions and its competitors.

1966
Pontiac's intermediate line was restyled again for 1966, gaining more curvaceous styling with kicked-up rear fender lines for a "Coke-bottle" look, and a slightly "tunneled" backlight. Overall length grew only fractionally, to 206.4 inches (524 cm), still on a 115 inch (292 cm) wheelbase, while width expanded to 74.4 inches (189 cm). Rear track increased one inch (2.5 cm). Overall weight remained about the same. The GTO became a separate model series, rather than an option package, with unique grille and tail lights, available as a pillared sports coupe, a hardtop sans pillars, or a convertible.

New Strato bucket seats were introduced with higher and thinner seat backs and contoured cushions for added comfort and adjustable headrests were introduced as a new option. The instrument panel was redesigned and more integrated than in previous years with the ignition switch moved from the far left of the dash to the right of the steering wheel. Four pod instruments continued, and the GTO's dash was highlighted by walnut veneer trim. The 1966 model year is viewed by many as the most iconic of all GTOs because of its independent model status and because it was the last year Pontiac offered the 389 Tri Power engine configuration.

Engine choices remained the same as the previous year. A new rare engine option was offered: the XS engine option consisted of a factory Ram Air set up with a new 744 high lift cam. Approximately 35 factory installed Ram Air packages are believed to have been built, though 300 dealership installed Ram Air packages are estimated to have been ordered. On paper, the package was said to produce the same 360 hp as the non-Ram Air, Tri Power car, though these figures are believed to have been grossly underestimated in order to get past GM mandates.

Sales increased to 96,946, the highest production figure for all GTO years. Although Pontiac had strenuously promoted the GTO in advertising as the "GTO Tiger," it had become known in the youth market as the "Goat." Pontiac management attempted to make use of the new nickname in advertising but were vetoed by upper management, which was dismayed by its irreverent tone.

1967
Styling remained essentially unchanged for 1967, but the GTO saw several significant mechanical changes.

Chevrolet was able to keep the tri-power set up to help with their image; the GTO was really becoming a serious competition problem for them. To compensate, the 389 engine received a slightly wider cylinder bore (4.12 inches, 104.7 mm) for a total displacement of 400 in³ (6.6 L). Torque increased slightly, from 431 to 441 ft-lbf (584 to 598 N·m) for the base engine, from 424 to 438 ft-lbf (575 to 594 N·m) for the optional engine but power remained the same. Testers found little performance difference, although the distinctive sound and fury of the Tri-Power was missed.

Two new engines were offered. The first was an economy engine, also 400 in³ but with a two-barrel carburetor, 8.6:1 compression, and a rating of 265 hp (198 kW) and 397 ft-lbf (538 N·m) of torque. Offered only with an automatic, it was not well received by GTO buyers. The second engine offered at an extra cost of US$263.30 over the standard high-output engine, was the Ram Air engine. The package, which included a functional hood scoop (much like the previous dealer-installed set-up), featured stiffer valve springs and a longer-duration camshaft. Rated power and torque were unchanged, although the engine was certainly stronger than that of the standard 360 hp (268 kW) GTO. It was available only with 3.90:1 or 4.33:1 differential gearing, and its "hotter" camshaft left it with a notably lumpier idle and less cooperative part-throttle response.

Emission controls, including an air injector system, were fitted in GTOs sold in California only.

The two-speed automatic was replaced with the three-speed Turbo-Hydramatic TH400, which was available with any engine. When the Strato bucket seats and console were ordered, the TH was further enhanced by the use of Hurst's Dual-Gate shifter, which permitted automatic shifting in "Drive' or manual selection through the gears. It was generally considered an equal match for the four-speed in most performance aspects. Meanwhile, the Tempest's inadequate drum brakes could be replaced by optional disc brakes on the front wheels (for US$104.79, including power boost), a vast improvement in both braking performance and fade resistance.

Hot Rod Magazine tested a 1967 Ram Air GTO with Turbo-Hydramatic and 3.90 gearing, and obtained a quarter-mile performance of 14.51 seconds @ 98.79 miles per hour (158.99 km/h) in pure-stock form, rising to 14.11 @ 101.23 miles per hour (162.91 km/h) with accessory drive belts removed, new spark plugs, and a slight modification to the carburetor. Car Life's similar car ran 0-60 mph (0-97 km/h) in 6.1 seconds and the quarter in 14.5 seconds @ 102 mph (163 km/h) with 4.33 rear differential. They were critical, however, of the Ram Air's behavior and tendency to overheat in traffic, as well as the ease with which a careless driver could exceed the 5,600 rpm redline in top gear (which limited the car to a maximum speed of 107 mph (171 km/h) with a 4.33 axle ratio). Nor was it cheap: for performance and appointments very similar to their 1965 Tri-Power, the price was US$4,422, a 20% increase.

The GTO sales remained high at 81,722.

Pontiac Grand Prix

Pontiac Grand Prix 1963

The Grand Prix appeared in the Pontiac line in 1962. It was essentially a standard Pontiac Catalina coupe with minimal outside chrome trim and sportier trim (bucket seats and a center console) inside. The performance-minded John De Lorean, head of Advanced Engineering at Pontiac, contributed greatly to the development of both the Grand Prix and the GTO. Early models had full access to the Pontiac performance option list, including the factory-race Super Duty 421 powertrain installed in a handful of 1962 and 1963 cars.


The full-size Catalina-based Grand Prix did very well through the 1960s, and is often credited with the move towards minimal exterior trim seen in the 1960s. Yet its clear resemblance to the other full-size Pontiacs caused some to consider it a lesser model than the other personal luxury cars. At the same time, the Grand Prix had a much stronger performance image than its competitors.

For 1963, the Grand Prix received revised sheetmetal shared with other full-size Pontiacs, but with its own squared-off roofline with a concave rear window that contrasted with the convertible-like roof ine of the 1962 Grand Prix and continued on the 1963 to 1964 Catalina and Bonneville. Other distinctive styling cues found on Grand Prixs of this era included "hidden" taillight lenses and exclusive grille work up front. Inside, Grand Prixs had luxurious interiors featuring all-vinyl bucket seats separated by a center console with a floor shifter, storage compartment, courtesy light and optional tachometer or vacuum gauge. Starting in 1965, the Grand Prix was offered with a no-cost option bench seat with folding armrest as an alternative to the bucket seats and console.

Standard engines included a 303 hp 389 in³ V8 with four-barrel carburetor and dual exhausts from 1962 to 1964 and a 325 hp version of same engine from 1965 to 1966. Optional engines included higher output four-barrel and Tri Power versions of the 389 and larger 421 in³ V8s with up to 376 hp. In 1967, the 389 was replaced by a 400 in³ V8 rated at 350 hp as the base engine while the larger 421 was replaced by a 428 in³ V8 with up to 390 hp.

Transmissions included a standard three-speed manual and optional four-speed manual or a Hydra-Matic transmission. The three-speed Roto Hydra-Matic was offered from 1962 to 1964 and replaced by a new three-speed Turbo Hydra-Matic for 1965 and later years.

A two-door hardtop was the sole body style available on the Grand Prix for all years except 1967, when a convertible was also offered as a one-year offering.

Pontiac Solstice Coupe

Pontiac Solstice Coupe

The making of a coupe

It is a modern sports car with classic lines. The roofline has a "fastback" shape with stylized "rails" that run from the front of the roof to the rear, culminating in a stylish and functional ducktail-style rear spoiler.
The coupe's roof is fixed aft of the B-pillars, with side windows and a rear liftglass for access to the cargo area. The roof panel is easily removed from the passenger compartment, and an optional soft roof cover stores in the cargo area.

The Engineering the design

Despite its dramatic new look, engineers made only minor structural changes to create the Pontiac Solstice coupe. The rear fenders and rear fascia are the same as those on the convertible. New taillight assemblies flow more smoothly into the tapered roofline.
The sleek lines of the new roof give the car a fresh appearance, only minimal changes were made to the body structure - it's a great example of building on an already solid foundation.


The Lightweight structure
The roof's structure was strengthened with additional support elements, including an aluminum roof bow attached with aluminum brackets. The bow and brackets are stiff, low in mass, a design feature that pervades the coupe's overall construction. The roof includes a lightweight sheet molding compound cover affixed to a rigid aluminum frame for additional lightweight support. A lightweight magnesium roof panel frame weighs just 31 pounds (14.2 kg) and can be removed by one person. The cover is also made of sheet molding compound.

The Interior additions
Much of the coupe's interior remains the same as that of the convertible. However, the area behind the seats was redesigned for easy access to the cargo area, and a storage tray was mounted directly behind the headrests.

Removing the folding-top mechanism made way for a new, flat cargo floor and several storage compartments. The cargo area's covered bins provide secure storage for smaller items. Cargo tie-down hooks help secure irregularly shaped items.

Review: Pontiac Solstice GXP Coupe

Climb into the Pontiac Solstice Coupe and there's an unsettling feeling of familiarity. We've been here before. And after driving off, it all begins to gel, although it has nothing to do with our previous stints in the drop-top variant. The Coupe feels like the unruly offspring of a night of passion between a C4 Corvette coupe and a Dodge Viper. And while the Solstice is nowhere near as large or as powerful as those two American icons, the DNA of both is undoubtedly present in this little machine – for good reason.

It's no coincidence that the history of the Solstice spans the Bob Lutz era at General Motors. After Lutz joined GM in 2001 to guide its product development, one of the first tasks he assigned the design staff was to create a new concept for the Detroit Auto Show. The Solstice was born, a stylistic hit was made and the convertible was rushed to production. Now, as Lutz is winding down his time at GM, the Solstice and the entire Pontiac brand are also fading off into the sunset. In many respects, this Solstice is symbolic of what was right and wrong with GM and Pontiac. And our time with the Solstice Coupe is a telling tale about the final new model from a vanishing brand.

In an odd twist of fate that mirrors the times we live in, the original sketches that gave birth to the Coupe were created by Franz Von Holzhausen; a new face in GM's design studio at the time. Since then, Von Holzhausen has had a tenure at Mazda and now leads the design effort at Tesla Motors where he's working on the Model S electric sedan. Von Holzhausen originally conceived the Solstice as a coupe, although when preparing the concepts for the 2002 Detroit and Chicago auto shows, a roadster was added to the program and was the first model to enter production. It wasn't until the 2008 New York Auto Show that we saw the production version of the Solstice Coupe.



On the morning the Solstice arrived, the skies opened up, lending themselves to a decidedly negative first impression. Upon opening the driver side door, water poured off the roof directly into the middle of the driver's seat. After voicing a few expletives and wiping the off the dampened throne, we slid in and – like a proper sports car – found ourselves a few inches from the ground. Arthritics take note: look elsewhere for your two-door thrills. Fortunately, the door sills aren't particularly wide or tall making entry and exit a bit easier, if slightly convoluted.

Even before turning the key, thoughts of the Viper immediately spring to mind. The interior is – to put it mildly – snug. The center tunnel is tall and wide to accommodate the transmission and drive-shaft, and unlike many modern sports cars, the Solstice's dashboard and center stack is relatively devoid of the dozens of buttons and switches to control the ever-growing number of features. It's minimalistic and refreshing, particularly in a purpose-built sports coupe.



Unfortunately, the execution of the interior leaves a lot to be desired. We could learn to live with the hard plastics, unwieldy color combinations and off-putting textures, but the horrendous fit and finish and ham-fisted ergonomics are a bridge too far. The gaps, particularly between the ends of the dashboard and the doors, are uneven and, in some cases, cavernous. The dark plastic covering the grab handle on the passenger side of the center stack appears as if it's going to pop off at a moment's notice, although the lack of rattling assured us it was firmly attached. Ergonomically, the disjointed theme continues, with the parking brake placed on the passenger side of the console and the window switches placed too far back on the door's armrest to be comfortably operated. And while we appreciate having a switch to toggle the stability control between normal, off and competitive modes, it's placement behind the steering wheel makes it easy to forget (design by lawyers?).



And then there's the issue of visibility... or lack there of. With the roof panel in place, looking out the low windshield requires you to lean ahead to see traffic lights when you're at the head of the pack. And while the shape of the side glass and downward slope of the roof pays dividends in the styling department, it makes the views out the side awkward at best and slightly dangerous at worse. Speaking of dangerous, rearward visibility with the roof fitted is nearly zero. The quarter windows are made utterly useless by the thick C-pillars and the view is further compromised by the small size and steep angle of the glass hatch. But enough moaning about silly things like laughable visibility and atrocious ergonomics. Let's get on to the good stuff.

When the Solstice debuted, the single biggest complaint was loathsome top mechanism. Amusingly, while poring over our research we found the following gem in the original 2002 press release for the concept:

"The drop-top is a simple 'one-hand'-operated manual fold-down that stows neatly underneath the speedster-style hard cover."

Apparently the production engineers never got the memo. Removing the targa top isn't quite one handed, but it's a lot easier than stowing the soft-top. Open up three latches, all reachable from the driver's seat, lift the panel off and stow. Ah, but therein lies the rub. While one person can remove and replace the lightweight top, there's nowhere to carry it on board so it has to be left at home. Pontiac does offer a fold-up soft-top that can be stowed in the trunk for emergencies, but shockingly, it's an $1,100 option. As a result, when the weather gets dubious, drivers are more likely to just leave the top in place, which is a shame because the Solstice is made for open-air driving.

While the Solstice's engineers may not have been able to figure out how to make a folding roof, they got it right with the rest of the mechanical bits. Unlike the Fiero that didn't receive proper suspension components until the third and final year of production, the Solstice has been right from day one. It has a proper double wishbone layout at all four corners, something that changed from the original concept, which utilized a Subaru WRX strut setup in the front. However, even the best suspension system only works if the four corners stay planted in the bends.



That's something that requires a stiff chassis and here the Solstice comes through. The Solstice's hydro-formed steel rails are remarkably flex-free, and even over the nastiest of roads, the Solstice never exhibited cowl shake or groaning. That's an admirable achievement considering the GXP variant has a fairly firm suspension, providing a tight ride that doesn't come at the expense of road manners. The wheel motions are tightly damped and spring rates are just right to keep the body motions in check while still absorbing bumps and potholes. Even with the excellent suspension setup, driving the Solstice reveals another element shared by the C4 and Viper: The front hinged clam-shell hood always seemed to be quivering while traveling at speed.



For a sports car with minimal body roll and pitch, the Coupe was actually quite comfortable to drive, certainly more than the Track edition of the Hyundai Genesis Coupe 3.8. The hydraulic rack and pinion steering provided excellent feedback and direct control with no slop. And the turbo'd four matches it perfectly. The Solstice GXP was the first application of GM's 2.0-liter turbocharged and direct injected EcoTec engine and this is a fine example of what the powertrain engineers in Warren, MI are capable of. With a solid (if mildly underrated) 260 hp and 260 lb-ft of torque, there's almost no discernible turbo lag, providing the sensation that a much larger engine lies under-hood. The only downside is the exhaust note, which is far too mild for such a flashy offering. A more aggressive song would be appreciated, but that's what the aftermarket is for.



When the clouds finally parted and the roof panel was stored in the shed, ironically, the Solstice Coupe came into its own. Once adjusted, the driving position is quite good, and while the thick, leather-wrapped steering wheel is a standard GM parts bin unit, it feels good in the hands and better in the corners. Unfortunately, our tester was equipped with the optional five-speed automatic and GM never spent the coin to add paddle shifters to the Solstice. Nonetheless, the torque of the DI Ecotec moves the Solstice with assurance anytime you stab the throttle and once the roads start to change direction, the Solstice proves to be a fun machine to pilot.

With the ESC in normal mode, the Coupe understeers as you approach the limits, and with competitive mode engaged, things loosen up just enough to create a serene sense of balance. The solid chassis, precise steering and responsive engine give the Solstice a feeling of assurance other roadsters aspire to, providing further proof that Pontiac was nearing the top of its dynamic game when it was pulled behind the shed to shuffle off this mortal coil.



The base, normally aspirated Solstice Coupe has a starting price of $26,225, while the turbocharged GXP ups the ante to $30,375. Add the automatic 'box, air conditioning and premium package, which brings with it leather covered seats, and the out-the-door price tag hits a credit-challenging $34,020. While the Coupe certainly isn't cheap, it's not ridiculous considering its capabilities in the bends and its real-world fuel economy. During our week-long stint in the Solstice, we saw 29 mpg on one highway run and a very respectable 25 mpg overall in mixed driving, both figures keeping in line with the EPA's estimates for the turbo model at 19/27, city/highway.

At this point, production of the Solstice (and Saturn Sky) has ceased and is unlikely to ever resume. Only a couple thousand coupes are thought to have been built and at the current sales rate they may be available for a while. It's a shame the Solstice never made it to a second generation. With a better interior and new top, it could have been a contender. But as it stands, it's a credible offering with a few too many flaws. And that, more than anything else, will solidify its place as a competent coupe destined for collector's garages.

Pontiac Solstice Coupe

Drawing inspiration from classic sports cars, the 2009 Pontiac Solstice coupe was created for drivers who appreciate both dramatic styling and balanced performance. Unveiled at the New York Auto Show as a GXP model, the Solstice coupe builds on the success of the convertible model while offering a greater range of all-season driving opportunities.

For drivers still wanting an open-air experience, the coupe also features a removable roof panel, fully opening the cockpit to all of the sensations of the road.

The new model has broader appeal . The coupe has all the design cues and pleasing performance of the original roadster, and is an all-season alternative for people who enjoy open-air driving.

Powertrain and suspension
Because the change to a coupe body style resulted in only a slight increase in curb weight, no drivetrain or suspension changes were necessary to shift from the convertible body structure. Initial tests have shown that the Solstice coupe will deliver ride and handling, acceleration, braking and fuel economy comparable to the convertible model.
The coupe is powered by a standard 2.4L Ecotec four-cylinder engine that generates 173 horsepower (129 kW), while the GXP version is equipped with a 2.0L turbocharged Ecotec engine with 260 horsepower (194 kW).

SEMA 2008: Pontiac G8 GXP Street Concept gets rave reviews on show floor

We couldn't help but listen to the comments of other onlookers as we closely inspected the G8 GXP Street Concept in the G8 booth. Every reaction was overwhelmingly positive, from the overall design to the motor. After all, what's not to like? For starters, the standard 6.2L V8 has been replaced with an LSX454 crate motor that uses the LSX Bowtie block, six-bolt LSX cylinder heads and a forged rotating assembly. In total, the 7.4L V8 pushes out a massive 638 horsepower and 600 lb-ft torque that's directed through a 6-speed automatic transmission. The exterior gets a makeover with new front and rear fascias, rocker panels, custom upper and lower grilles and black chrome trim. Inside, the G8 GXP Street Concept also gets custom leather trimmed seats, a new gauge cluster and more black chrome. Yeah, it's basically a four-door ZR1.

GM bringing Pontiac G8 ST concept

Pontiac's G8 ST will likely not be used much for hauling joists and sonotubes, and General Motors took note of that before preparing one for SEMA. Instead, the concept has been dolled up with goodies that may make it to the GM Accessories catalog once the G8 ST goes on sale in late 2009. The most visible enhancements are on the outside. The paint is called Liquid Hot, and custom 20-inch wheels handsomely stuff the fenders. Making the car look more menacing is a reduced ride height, too. Inside, interior tweaks dress up the seats, the steering wheel and the shift knob with red inserts, and GM Accessories is contemplating making the custom interior trim kit and hard tonneau cover on the SEMA car available for purchase. With its vestigial bed and big V8, we predict the G8 ST will be hauling mostly ass.

RWD Pontiac G8 will be dead in five years

It looks like things will be getting a lot less exciting at Pontiac, as some reports indicate that the erstwhile performance brand will be losing its best performers. Despite the fact that the G8 sedan has seen nothing but positive press from the media, including your humble scribes here at Autoblog, the realities of fuel economy and the global economy appear set to kill off the rear-wheel drive performance sedan in the prime of its short life. GM will reportedly not renew the G8 after its Holden-sourced chassis architecture is redesigned following a planned five-year run.

The Pontiac Solstice in both coupe and convertible forms is also unlikely to see a second generation. Unfortunately, the Solstice, Saturn Sky and their Opel spin-off don't generate enough sales to support another go-round, which could leave Pontiac with exactly zero vehicles with overtly sporting pretensions. While the G6 may be a decent car, it and a Cobalt derivative in the form of the G5 and a rebadged Aveo known as the G3 do not a BMW competitor make. What does this mean for the future of Pontiac as a brand? We'll see.

2009 Pontiac G3 Wave: Excitement has left the building

For a little while there, it looked like Pontiac was getting its mojo back. The G8 is terrific, the Solstice GXP Coupe is ready to join the roadster, and the even more awesome G8 GXP is waiting in the wings. All rear-drive. All meant to be fun. And then GM goes and does this.

Behold, friends, the 2009 Pontiac G3 Wave. Yes, that's an Aveo5 with Poncho nostrils, and it reeks of product strategy that's more 1989 than 2009. Why not just call it G3 Le Mans? You know, in honor of the last Daewoo-sourced trashback that helped turn that whole "We Build Excitement" thing into a punchline. By comparison, this makes the equally distressing Pontiac G5 look like a Corvette ZR1 on the cool meter -- and trust us, this is the only scenario in which you'll ever see those two models mentioned in the same sentence again.

The press release after the jump explains that, "More than ever, fuel economy is an important factor in Pontiac's formula of style and performance." In the G3 Waveo, "performance" means red gauge lighting and 106 horsepower channeled through a 5-speed manual or cutting-edge 4-speed automatic. It also gets over 30 mpg highway, so we're supposed to bust out the Veuve Clicquot and celebrate this new era of efficiency at the Pontiac division. Thanks, but we'll skip this party.

The G8 and Solstice are genuinely exciting, desirable cars that had restored some luster to the Arrowhead, but this...

Pontiac G8 GXP officially rated at 415 hp

The V8-powered Pontiac G8 GT has garnered a fair amount of respect around Autoblog HQ, with almost everyone who's spent time behind the wheel singing the praises of the Aussie-imported four-door muscle car. We're all suckers for rubber-melting torque and rear-wheel motivation, and even El Capitan Neff has thought about retiring his Alero for a shot at G8 ownership. For the rest of us, a six-speed manual would seal the deal.

Next year Pontiac will finally offer a proper cog swapper on its G8 GXP, and not only do drivers get to row their own gears, but they're getting an extra 13 horses and 15 lb.-ft. of torque to boot. The SAE has finally performed its official testing on the 6.2-liter LS3 V8 and output is up to 415 horsepower and an equal amount of twist.

With 19-inch HSV wheels framing 14-inch (front) and 12.76-inch (rear) discs and Brembo calipers, a standard LSD and a stiffened suspension, the additional power is just another reason to be smitten by the Pontiac G8 GXP. That, and the Tremac TR060 manual.

2010 Pontiac G8 ST may get direct-inject V6

The Pontiac G8 Sport Truck was originally supposed to be powered only by General Motors' 361-horsepower 6.0L V8, but tough fuel economy standards and customer demand for fuel efficient products have conspired to change the General's plans. Edmunds Inside Line quotes an anonymous senior engineer at the General saying that the unique sport ute will receive automaker's 3.6L V6, as well. That's good news for fuel economy, but the better news is that the 3.6L V6 of choice will be the direct injection versoin. That will likely give the G8 ST the same 300+hp as the 2010 Camaro and Cadillac CTS. That should also make the base ST more appealing to enthusiasts and the average Joe, with more power at the pedal and a healthier torque curve. The DI version of GM's 3.6L V6 will also likely be available in the base G8 sedan for the 2010 model year, as well.

It makes sense that GM would go with direct injection for the G8 ST, as the General has already promised the powerful V6 for the Chevy Traverse and Camaro. Putting DI in more vehicles will help drive down the cost of producing these more high-tech engines economy of scale while also giving customers V8ish performance with V6ish fuel economy. Keep in mind, however, that though a GM engineer was quoted, none of this is official word from GM, so plans could change.

Pontiac G8 ST

We often go poking around General Motors' media resources, so imagine our surprise when we were searching for something totally unrelated and found fresh images of Pontiac's iteration of the Holden Ute. Still warm like just-baked cookies, the images show off a great looking dark-hued modern-day El camino. And for what do we deserve a new batch of G8 ute pics? They accompany word from on high that the official name for this trucklet has been decided. Meet the Pontiac G8 ST.

You may remember that GM solicited submissions, or rather suggestions, for what the G8 ST should be named. But after months of waiting and however many submissions, the best they could do was G8 ST? That's the name they started with! Now we feel all cheap and used, like GM knew what they were going to call this thing all along. Whatever, it will be holding court as the king of awesome in your local Pontiac dealer's showroom in late 2009 as a 2010 model. The 74-inch cargo bed and 3,500 lb towing capacity will allow you to haul more than just ass, though the V8 will surely facilitate that nicely.

Pontiac G8 ST at a Glance

• Sports car with truck-like cargo and towing capabilities
• V8 engine with Active Fuel Management linked to six-speed automatic
• 74-inch cargo bed and 3,500 lb towing capacity
• Estimated fuel economy near top of vehicles with comparable cargo/towing capacity
• Available in late 2009 as a 2010 model

PONTIAC NAMES ALL NEW SPORT TRUCK THE "G8 ST"

Segment-Defining Vehicle on Target for Late 2009 Launch

Detroit - After sifting through more than 18,000 possibilities, Pontiac has chosen to keep it simple, naming the recently revealed G8 sport truck the "G8 ST."

Thousands of fans submitted suggestions during a "Tame the Name" promotion, which delayed a final announcement until each possibility was considered and cleared for possible trademark use.

"Frankly, we were blown away by both the volume and quality of the names that were submitted," said Craig Bierley, BPG product marketing director for cars and crossovers. "'G8 ST' was one of the most popular suggestions, plus we noticed a far broader trend toward simple, easy-to-remember names."

"El Camino" was also a sentimental favorite, given the G8 ST's resemblance to the classic Chevy.

"We actually thought very long about El Camino," said Bierley. "In the end, we felt it was more appropriate to honor the El Camino's unique place as part of Chevy's heritage and not use that nameplate on a Pontiac."

Perhaps the ultimate reflection of the blurring line between cars and trucks, the G8 ST will create a unique niche segment in the marketplace: a sports car with truck-like cargo and towing capabilities. Sharing the basic architecture and 361 hp V8 engine as the G8 GT performance sedan, it will offer a 73.9-inch cargo bed that has 42.7 cubic feet of cargo space and can carry a payload of 1,000 pounds (453 kg) or tow a 3,500-pound (1,587 kg) trailer.

Thanks to its six-speed automatic transmission and Active Fuel Management system, the G8 ST should offer some of the best fuel economy numbers for V8-powered vehicles with similar cargo/towing ratings while still turning in zero-to-60 times of 5.4 seconds.

The G8 ST will be available in late 2009 as a 2010 model and will be backed by GM's industry best 100,000 mile, 5-year powertrain warranty. Pricing will be announced closer to availability.

Pontiac G8 GT with 557 bhp by APS

APS, the specialist tuning house with over 25 years of turbo tuning, has turned a Pontiac G8 into something of a Pontiac GR8 (or great). Realizing some potential in the 6.0-litre V8 used in the G8, APS then got to grips with it by installing an intercooled twin turbo system, which is cleverly mounted under the chassis so heat moves away from the engine. Clever yes, if you live in a town with no speed humps and other road oddities.

What power then? How’s about 557 bhp on the trot? And torque? That’s 583.8 ftlb. It’s good figures by any measure, and APS says its system ensures access to all this munchy power and delivers through quite a flat range. The intercoolers work hard to cool things down such that APS claims a quarter mile run twice or more up and down the straight will not even sweat its G8 system.

So those who own VXR8s and HSV Clubsport R8s will be welcome at APS to see how much further things can go. APS themselves reckon there’s quite a few more horses stored under the ‘hood here and perhaps in time it may all come home to roost.

2009 Pontiac Solstice Coupe

Pontiac will unveil at the New York Auto Show the 2009 Solstice Coupe. It will arrive in dealerships in early 2009. The new model is inspired by the Solstice coupe concept shown at the North American International Auto Show in 2002.

Despite its dramatic new look, engineers made only minor structural changes to create the Solstice coupe. The rear fenders and rear fascia are the same as those on the convertible. New taillight assemblies flow more smoothly into the tapered roofline.

The coupe is powered by a standard 2.4L Ecotec four-cylinder engine that generates 173 hp, while the GXP version is equipped with a 2.0L turbocharged Ecotec engine with 260 hp.

For drivers still wanting an open-air experience, the coupe also features a removable roof panel, fully opening the cockpit to all of the sensations of the road.

“Today’s Solstice is the top-selling roadster in the U.S., and we believe this new model has even broader appeal,” said Jim Bunnell, Buick-Pontiac-GMC general manager. “The coupe has all the design cues and pleasing performance of the original roadster, and is an all-season alternative for people who enjoy open-air driving.”

The coupe is expected to arrive in Pontiac dealerships in early 2009.
The making of a coupe

The new coupe was inspired by the Solstice coupe concept shown at the North American International Auto Show in 2002. True to the concept, it is a modern sports car with classic lines. The roofline has a “fastback” shape with stylized “rails” that run from the front of the roof to the rear, culminating in a stylish and functional ducktail-style rear spoiler.

The coupe’s roof is fixed aft of the B-pillars, with side windows and a rear liftglass for access to the cargo area. The roof panel is easily removed from the passenger compartment, and an optional soft roof cover stores in the cargo area. A home storage case for the roof panel will be offered through GM Accessories.
Engineering the design

Despite its dramatic new look, engineers made only minor structural changes to create the Solstice coupe. The rear fenders and rear fascia are the same as those on the convertible. New taillight assemblies flow more smoothly into the tapered roofline.

“The Solstice coupe represents a major collaboration of design and engineering,” said Bruce Kosbab, chief engineer. “The sleek lines of the new roof give the car a fresh appearance, yet only minimal changes were made to the body structure – it’s a great example of building on an already solid foundation.”
Lightweight structure

The roof’s structure was strengthened with additional support elements, including an aluminum roof bow attached with aluminum brackets. The bow and brackets are stiff, yet low in mass, a design feature that pervades the coupe’s overall construction. The roof includes a lightweight sheet molding compound cover affixed to a rigid aluminum frame for additional lightweight support. A lightweight magnesium roof panel frame weighs just 31 pounds (14.2 kg) and can be removed by one person. The cover is also made of sheet molding compound.
Powertrain and suspension

Because the change to a coupe body style resulted in only a slight increase in curb weight, no drivetrain or suspension changes were necessary to shift from the convertible body structure. Initial tests have shown that the Solstice coupe will deliver ride and handling, acceleration, braking and fuel economy comparable to the convertible model.

The coupe is powered by a standard 2.4L Ecotec four-cylinder engine that generates 173 horsepower (129 kW), while the GXP version is equipped with a 2.0L turbocharged Ecotec engine with 260 horsepower (194 kW).
Interior additions

Much of the coupe’s interior remains the same as that of the convertible. However, the area behind the seats was redesigned for easy access to the cargo area, and a storage tray was mounted directly behind the headrests.

Removing the folding-top mechanism made way for a new, flat cargo floor and several storage compartments. The cargo area’s covered bins provide secure storage for smaller items. Cargo tie-down hooks help secure irregularly shaped items.
