Pontiac G8 GXP

The Pontiac G8 GXP was a sleek, powerful sedan that hit the market in 2008. It was designed to be a muscle car for the everyday driver, with a 6.0-liter V8 engine that could produce 415 horsepower and 415 lb-ft of torque. The car was built on the same platform as the Holden Commodore, which was a popular car in Australia, but it was never quite as successful in the United States.
