The G8 is a rear-wheel-drive sedan, Pontiac's first full-size car since the Bonneville was discontinued in 2005. It becomes the Pontiac flagship, being bigger than the mid-size front-wheel-drive , and it takes that spot at the top of the line with pride, being a very good car, with no weaknesses. At least not with the V8-engined GT, which Pontiac accurately bills as the most powerful car on the market for under $30,000. But it's not just powerful; there's a wonderful six-speed manual automatic transmission, the ride is comfortable without being soft, and the handling is taut. It all works.

And it looks good: smooth and muscular, with an unmistakably Pontiac nose. The interior is comfortable and tidy, with good instrumentation and a reasonably roomy rear seat. The standard cloth seats are excellent, with good bolstering and lumbar support. Leather is optional. The GT features an 11-speaker Blaupunkt sound system.

Even with 361 horsepower, the 2008 Pontiac G8 GT gets 15 city and 24 highway miles per gallon, on regular fuel. Premium is recommended but not required. When Pontiac measures the horsepower on the dynamometer, guaranteed, they use premium fuel.
