The Pontiac G8 concept car, the spiritual successor to one of General Motors’ most celebrated performance sedans, is unveiled Feb. 7, 2007, at the Chicago Auto Show.
The all-new performance sedan from Pontiac, the 2008 G8, introduced an all-new rear-wheel-drive platform -- dubbed Zeta -- shared with the Holden Commodore from GM’s Australian subsidiary.
Ronald Reagan was president the last time Pontiac sold a rwd Grand Prix.
Pontiac initially sold two G8s: a base model powered by a 3.6-liter V-6, rated at 261 hp and 250 pounds-feet of torque, with a five-speed automatic; and a GT packed with a 6.0-liter V-8, rated at 362 hp and 391 pounds-feet of torque, mated to a six-speed automatic.
Both transmissions featured a manual shift mode. A six-speed manual transmission became available with the V-8 after the launch. The V-8 also was equipped with cylinder deactivation technology. The GT offered standard limited-slip differential for improved traction.
Pontiac’s Chicago show car, while representative of the production GT, also featured some tuner touches: 20-inch chrome wheels (18-inch wheels were standard, and 19-inch wheels were available), lowered ride height, high-performance brakes with painted calipers, custom interior trim with leather-wrapped dash, a Phantom Grey paint job and a conceptualized version of the Pontiac badge.
