Pontiac is toast at the end of the 2010 model year.

But the Pontiac G8 sedan might survive with another GM badge,

 says Tom Stephens, General Motors' vice chairman of global product development. "I know there's still discussions on it," says Stephens. "But Chevrolet already has several sedans. How many sedans do you need to cover the waterfront?" The G8, engineered and assembled by GM subsidiary Holden in Australia, has been a bright spot for Pontiac. With little advertising support, the sporty, rear-drive sedan, which starts at $29,000 including freight, has sold well. Some versions have the same V-8 engine as the Chevrolet Corvette. Some enthusiasts are lobbying GM to turn the G8 into a Chevrolet Impala SS. The current front-drive Impala SS is being phased out at the end of the 2009 model year. The G8 also could morph into a performance sedan for Buick. Buick has not had a rear-drive performance car since the mid-1980s.
