Pontiac thought that a rear-wheel-drive sedan would help them fight their European competitors. With a Pontiac redesign and small-block V8 engine, the G8 was an effective performance sedan, too. The base engine was a solid 3.5-liter V6 producing 256 HP. But the real deal was the G8 GXP with a 6.2-liter V8 delivering 415 HP. Better yet, the G8 came with high levels of standard equipment, as well as a long list of optional extras.
