Models with the 200-hp V6 have good acceleration from any speed, including the convertible, which weighs some 400 lb more than the sedan. A test manual-transmission GTP coupe steadily builds power with smooth throttle response. Automatic and manual transmissions are responsive, though the latter suffers from a scraping metal feel during gear changes. A test GT sedan and convertible averaged 19.5 mpg, and a manual GTP coupe averaged 19.1. All G6s use regular-grade fuel. No G6 matches the refinement, composure, or quietness of the class-leading Honda Accord or Toyota Camry in ride and handling, but these Pontiacs don't significantly trail them either. G6 is competent in these measures with respectable ride control and good grip in fast turns. Steering feel is overly light at low speeds, which helps in parking maneuvers but causes numbness on the highway. The hardtop convertible is stiffer than competitive soft tops from Chrysler and Toyota, but body flex is still noticeable. The hardtop makes the convertible nearly as quiet as the sedan, but all G6s still allow some engine, road, and wind noise to get into the cabin. G6's interior is a step up in appearance and materials quality than the Grand Am it replaces. Seats are softer than in many rivals, and testers say they are short on long distance support. The standard tilt/telescope steering wheel is a comfort plus. Vision is impeded by tall front headrests and thick roof pillars. The rear seat has ample leg room, but the sloping roofline limits head room in all models. The narrow trunk has a small opening and tall liftover, so loading bulky items is a chore. The rear seatbacks unlatch from the trunk but don't fold completely flat. The convertible has 5.8 cu ft with the top up, and that shrinks to 1.8 cu ft with the top down.

Value for the Money
G6 lacks the well-toned feel of a Honda Accord, the isolating comfort of a Toyota Camry, or the raw coltishness of a Nissan Altima. But it undercuts them all on price, especially with a V6 engine. The convertible benefits from its retractable hardtop and impresses for its solidity and smart pricing. Frequent discounts and a wide selection of safety and convenience features add to its appeal. The G6 coupe is too large for the interior space it provides, making a sedan the wisest choice here.
