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.

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.
