2005 Pontiac G6 Review

With the new G6, Pontiac has put a stake in the ground, challenging the Honda Accord, Nissan Altima and Mazda 6 to beat it on sheer value. That was the central message at the recent introduction of the car that finally replaces, and becomes the sixth generation of, the Pontiac Grand Am, first introduced in 1974 as a much larger car, and evolving down to the all-new Generation 6, or G6.

Initially, the Pontiac G6 is being launched as a sporty four-door sedan, available in SE and GT trim levels. Initially, all will be equipped with a 3.5-liter V6. By spring 2005, the G6 line will include sporty two-door coupes and convertibles, each with unique styling. Three engines will be available: a four-cylinder, a 3.5-liter V6, and a high-performance 3.9-liter V6, the latter in a new GTP model. All come standard with four-speed automatic transmissions, though a high-performance six-speed manual gearbox will be available for the GTP.

We found the G6 has good road manners even when driven hard, benefits of its long wheelbase and European-designed architecture. The sedan is roomy and plush with excellent overall function and its price point will make it popular choice as a mid-size sedan. The G6 offers some interesting features. The car can be started remotely by pressing a button on the key fob from the comfort of your home, a real luxury on bitter cold winter mornings or sweltering summer afternoons. A Panoramic roof is available with panels that slide rearward, creating a sunroof large enough for the back-seat riders to enjoy an open-air experience.

This car, according to Pontiac, is the living expression of what all future Pontiacs will look like and act like, a redefinition of Pontiac's longstanding "Excitement" theme. All of the previous earmarks of a Grand Am are gone, along with the name.

Gone are the massive side cladding panels and standoff rear spoiler associated with the Pontiac Grand Am. Instead, there is a single spear running down the sides of the G6 with a delicate integrated spoiler lip on the trailing edge of the decklid. That's on the GT models. The stripper version, the SE, has almost no decoration at all. It's a bit soulless in style when compared to the previous high-energy, hot-looking Grand Am, even out-dulling the Honda Accord.

The Pontiac designers were handed a much longer wheelbase, at 112.3 inches some five inches longer than the old Grand Am's, and they have made the most of it in terms of interior roominess. A 6-foot, 4-inch passenger can sit behind a 6-foot, 4-inch driver with plenty of room in models with no sunroof or the conventional sunroof. Those with tall friends or family may want to consider the new Panoramic sunroof is powered by a motor that takes up a big chunk of headroom at the trailing edge of the headliner.

The all-new 2005 Pontiac G6 is built in Michigan on GM's international Epsilon platform, from parts and ideas that used on the Saab 9-3, Opel Vectra, Chevrolet Malibu sedan and Malibu Maxx wagonette, all introduced over the past two years.

GM's Epsilon architecture is behind the long-wheelbase G6's ride and handling finesse, with a structural stiffness that helps the G6 achieve a 27.3 Hz bending frequency, a big number that ranks with most luxury cars. Pontiac says the car is designed with three major "torque rings" that add stiffness and strength without taking up too much space or adding weight. In addition to the torque rings, the G6 structure also uses high-strength steel for about 60 percent of underbody components and central tunnel. Rather than just a single layer of sheet steel, the tunnel has an extra piece of steel welded between it and the floor pan. The stiff body uses fully isolated front and rear subframes to carry the heavy stuff, and the front one is hydroformed for strength and light weight.
