Although 2007 marks just the third year of the Pontiac G6, a number of changes should further boost its appeal among style-conscious and performance-minded shoppers. Based on GM's "Epsilon" platform, the G6 shares its basic architecture with the Chevrolet Malibu Maxx, itself a lengthened version of the Malibu sedan. As such, the Pontiac G6 offers passengers plenty of room to stretch out thanks to its long, 112.3-inch wheelbase. In addition, that generous span also makes for a smooth and stable ride. This year brings more power for the base 3.5-liter V6, which provides up to 224 horsepower, while the performance leader GTP gets a new 3.6-liter 252-hp mill. Another improvement is the adoption of hydraulic power steering in the GT, which promises more road feel than the former numb electric setup that only the base sedan retains.
