The VE Commodore was exported to the United States, where it was sold by Pontiac as the G8. The G8, a rebadged Holden Commodore, was released in early 2008 for the 2008 model year in the United States, and in 2008 for the 2009 model year in Canada (after-1917 Pontiac 4-door sedan, 1918 Pontiac 4-door sedan, 1919 Pontiac 4-door sedan, 1920 Pontiac 4-door sedan, 1921 Pontiac 4-door sedan, 1922 Pontiac 4-door sedan, 1923 Pontiac 4-door sedan, 1924 Pontiac 4-door sedan, 1925 Pontiac 4-door sedan, 1926 Pontiac 4-door sedan, 1927 Pontiac 4-door sedan, 1928 Pontiac 4-door sedan, 1929 Pontiac 4-door sedan, 1930 Pontiac 4-door sedan, 1931 Pontiac 4-door sedan, 1932 Pontiac 4-door sedan, 1933 Pontiac 4-door sedan, 1934 Pontiac 4-door sedan, 1935 Pontiac 4-door sedan, 1936 Pontiac 4-door sedan, 1937 Pontiac 4-door sedan, 1938 Pontiac 4-door sedan, 1939 Pontiac 4-door sedan, 1940 Pontiac 4-door sedan, 1941 Pontiac 4-door sedan, 1942 Pontiac 4-door sedan, 1943 Pontiac 4-door sedan, 1944 Pontiac 4-door sedan, 1945 Pontiac 4-door sedan, 1946 Pontiac 4-door sedan, 1947 Pontiac 4-door sedan, ). Production stopped in mid-2009, following the GM decision to suspend the Pontiac brand. While available, the G8 took the place in the Pontiac lineup of both the Pontiac Bonneville, which ceased production after the 2005 model year, and the Pontiac Grand Prix, which ceased production after the 2008 model year. The G8 was Pontiac's first full-size car since the Bonneville.

Recent Changes[]

  • In addition to the sedan, a two-seat coupé utility called the G8 ST (for Sport Truck) was shown at the New York International Auto Show in March 2008. Based on the Holden Ute, it was built on the same G8 platform with a 73-inch (1,900 mm) cargo bed. The ST had the same 361 hp (269 kW), 6.0-liter V8 used in the G8 GT, as well as the 3.6-liter, 256 hp (191 kW) V6. After a naming contest with more than 18,000 suggestions, the name remained the G8 ST. The G8 ST, slated for release as a 2010 model, was to be Pontiac's coupe utility, and GM's first coupe utility in the United States since the Chevrolet El Camino was discontinued in 1987. In January 2009, GM announced to Pontiac dealers that the G8 ST was cancelled due to budget cuts and restructuring.

The base G8, referred to in Pontiac sales literature as the "G8 Sedan", is available with a 3.6-liter High Feature V6 engine, producing 256 hp (191 kW). The only transmission available is a five-speed GM 5L40-E automatic; fuel economy is officially rated at 17 mpg‑US (14 L/100 km) city/25 mpg‑US (9.4 L/100 km) highway. Base G8 models come standard with six airbags (including full-length side curtain airbags), traction control, electronic stability control, dual tailpipes, 18-inch alloy wheels (fitted with either all-season or summer performance tires), sports body kit, fog lights, power windows and locks, cruise control, black cloth seats and a seven-speaker audio system, including front center speaker, single-disc CD player, and auxiliary input jack. A "Comfort And Sound" package is available on V6 powered G8s, which upgrades the seven-speaker audio system and manual HVAC controls to the 11-speaker audio and automatic climate control found in the GT model. The "Premium" package upgrades the Sedan's cloth seats to leather seating surfaces, driver and passenger heated seats, six-way power driver seat adjuster, 6-way power front-passenger seat adjuster, rear center armrest, leather-wrapped shift lever, and the GT's standard leather-wrapped steering wheel. Both the base G8 and the GT utilize the "FE2" suspension package.

G8 GT[]

  • Dual-zone air conditioning
  • Leather-wrapped steering-wheel with controls
  • 11-speaker audio system

The GT comes with a 361 hp (269 kW) 6.0 L (364 cu in) Generation IV V8, featuring a 6-speed 6L80 automatic and Active Fuel Management, capable of reaching 60 mph (97 km/h) in 5.2 seconds, with quarter-mile times as low as 13.4 seconds. The G8 GT averages a fuel economy of 15/24 mpg (city/highway). A 6-speed manual was being considered as an option on the GT model, but Pontiac decided against offering it, stating that it would instead be offered as an option on the G8 GXP. One change in 2009 was the deletion of the center stack oil pressure and voltage gauges. Midway through the 2009 model year a few changes were made to the G8 GT, including an additional pair of catalytic converters which reduced engine output to 355 hp (265 kW), the addition of bluetooth and rear cup holders that pulled out from under the rear seats. In addition to the larger engine and six-speed transmission, GT models also contain additional equipment, including all of the standard Sedan features plus quad tailpipes, clear taillight lenses (as opposed to the Sedan's traditional red taillights), automatic dual-zone air conditioning, a larger center-console display screen, and an 11-speaker Blaupunkt premium audio system with 2 subwoofers, six-disc CD changer, and auxiliary input jack. Some (but not all) of these features are available as options on the base model. A sports package is available on the GT, adding sport metallic pedals, QS4 19" machine-faced aluminum wheels, summer performance tires and a slightly smaller diameter, leather-wrapped Sport steering wheel.


A G8 GXP version was shown at the New York International Auto Show in March 2008 with a 6.2-liter 402 hp (300 kW) V8 from the Chevrolet Corvette and a six-speed manual transmission. The production version of the GXP was more powerful with its LS3 V8 producing 415 hp (309 kW) and 415 lb⋅ft (563 N⋅m) of torque. The six-speed automatic was standard while a six-speed Tremec TR-6060 manual transmission was available. The GXP reached 60 mph (97 km/h) from a standstill in 4.5 seconds, a quarter-mile time of 13.0 seconds at 109.6 mph (176.4 km/h), and 0.90g (8.8 m/s2) of lateral acceleration on a skidpad. The GXP has an upgraded, Nürburgring-tuned FE3 suspension package, as well as larger, ventilated Brembo disc brakes. It also features a unique front bumper cover and a rear (non-functional) diffuser to differentiate it from the standard Sedan and GT models. Total sales of the Pontiac G8 GXP were 1,829 units. Only a limited production of G8 GXP were available in Canada. 10 units were shipped to Canada, however, only 4 were sold to customers. The remaining 6 were disposed of through GM's internal system. In 2014, General Motors released the Chevrolet SS, which was in essence the next generation of the G8 GXP. It was based on the new VF chassis Holden Commodore, the successor to the VE chassis Commodore on which the G8 was based. Both the G8 GXP and the SS shared the same LS3 V8 engine, with the new SS sporting the engine with minor improvements. Horsepower for both remained 415, with 415 lb. ft. of torque.

Resale Values[]












Many on the new forum [] have criticized the cars tailights and wheels more than anything else. As with the 2004-2006 Pontiac GTO, however, bumpers and lights can be swapped from the Austrailian version of the car, the Holden Commodore.

First Generation: (2008–2009)[]

The G8 is based on the GM Zeta platform, created by Holden for the VE Commodore in the Australian market. The G8 differs from the Commodore mainly in frontal styling and interior details. At the January 2007 North American International Auto Show in Detroit, GM chairman Bob Lutz confirmed that GM intended to import Holden Commodores into North America as Pontiac G8s. The news was not planned to be officially announced until the Chicago Auto Show in February.

Holden chairman Denny Mooney announced that the G8 is imported from the Elizabeth, South Australia plant, South Australia for the life cycle of the car, but refused to comment on possible future production at GM's Oshawa, Ontario facility. At the 2007 Chicago Auto Show, GM Global Chairman Bob Lutz announced that the G8 was expected in US Pontiac dealerships in "early 2008". On 4 July 2007 the first Pontiac G8 prototypes rolled out of the Elizabeth assembly plant in Australia. General production began 18 December 2007. The G8 was the first rear-wheel drive four-door sedan sold under the Pontiac name since the 1986 Bonneville and Parisienne. However, at the time of the G8's release, Pontiac did offer the rear-wheel drive Solstice. The then recently discontinued GTO (as well as the Firebird/Trans Am before it), also utilized the rear-wheel drive layout. The GTO was another Holden product, known as the Monaro in Australia, repurposed and rebadged for U.S. consumption. Production was discontinued in 2006 due to new US safety regulations and the architecture being phased out worldwide in favor of the new Zeta platform on which the G8 is based.

For the 2008 model year, the Pontiac G8 was initially offered in six colors: Stealth Blue, Liquid Red, Ignition Orange, White Hot, Magnetic Gray, and Panther Black. Stealth Blue was discontinued after the first batch of vehicles were shipped from Australia. First deliveries to dealerships were posted on GM's website in March 2008, with comments that initial sales were brisk. Subsequently, May 2008 monthly sales were reported at 1,832 units against a May 2007 sales volume of 12,230 units for the Grand Prix.

The 2009 model year adds the GXP version powered by a 415 hp (309 kW) 6.2-liter V8 engine with a standard 6-speed automatic transmission or optional six-speed manual transmission (see above). The GXP is available in all standard G8 colors.

The G8 lineup also adds standard XM Satellite Radio, with Bluetooth connectivity provided later in the year, and four new exterior color choices: Maverick Silver Metallic, Sport Red Metallic, Stryker Blue Metallic and Pacific Slate Metallic. Meanwhile, Stealth Blue and Ignition Orange were unavailable for 2009 (Stealth Blue having already been eliminated during 2008 model year production). Also for 2009, the oil pressure and battery voltage gauges at the top of the center console were eliminated. Heavy criticism among the automotive press of the outdated appearance of these red LED gauges no doubt factored heavily in their removal. The gauges were simply replaced with a small storage compartment.

National Safety Agency Ltd., an Australian company in a joint project with the Los Angeles Police Department (LAPD) displayed a prototype squad car based on the Pontiac G8, at the APCO 2009 Conference in Sydney in March 2009. The vehicle is fitted with a large portrait format touch screen in the center console, replacing the clutter of controls common in police vehicles.

The last Pontiac G8 rolled off the assembly line on June 19, 2009.
