The 2009 Pontiac G8 is available in three variants, distinguished primarily by engine size and horsepower.
The base G8 ($28,190) features a 3.6-liter, dual-overhead-cam V6, with 256 horsepower and 248 pound-feet of torque, and a five-speed automatic transmission. It comes with cloth upholstery, a full complement of power features, including seats, a seven-speaker sound system with single CD and auxiliary input jack, and 18-inch aluminum wheels. For 2009, XM satellite radio and Bluetooth connectivity for mobile phones have been added to the standard-equipment list.
The G8 GT ($31,555) upgrades to a 6.0-liter V8, generating 361 horsepower and 385 pound-feet of torque, and a six-speed automatic. The cam-in-block V8 features GM's Active Fuel Management technology, which switches from eight-cylinder to four-cylinder operation during light-load driving conditions to improve fuel economy. The GT also adds dual-zone automatic climate control and upgraded Blaupunkt audio with 11 speakers and six-CD changer.
Options are few. The Comfort and Sound Package ($795) for the base model adds dual-zone climate control and the stereo upgrade, bringing interior features up to GT specification. The Premium Package for the G8 ($1,375) and GT ($1,250) includes leather upholstery and heated front seats with more adjustment. A Sport Package for the GT ($600) adds sport pedals and 19-inch wheels with summer performance tires. Stand alone options are limited to a power sunroof ($900) and all-season tires for the 19-inch wheel package ($150).
The G8 GXP ($37,610) is powered by a 402-hp, 6.2-liter LS3 V8 and comes with the six-speed automatic. The GXP adds other performance upgrades, including a more aggressively tuned suspension and Brembo brake system. A six-speed Tremec manual transmission is optional.
Safety features on all G8s includes frontal airbags and side-impact airbags for front passengers, with curtain-type head protection airbags front and rear. Active safety systems include full-feature ABS, traction control and electronic stability control. There's also a tire-pressure monitor. The standard OnStar package includes a one-year subscription to the Safe and Sound accident reporting service, which will direct emergency crews to your location should the airbags deploy.
