The Pontiac G6 models are attractive cars. They have the smooth styling of the latest-generation Pontiacs, sharing cues with the Solstice roadster and other models and sort of a Lexus/Toyota look from the rear. In fact, the G6 led this latest Pontiac styling revolution. Its clean, uncluttered lines are quite pleasing.

Instead of side cladding, there is a single spear running down the sides of the G6 with an optional delicately integrated spoiler lip on the trailing edge of the decklid.

GTP models look similar to the GTs, but with a spoiler and chrome exhaust tips. The base version has almost no decoration at all, and is relatively dull-looking.

The coupe and convertible inject a little more excitement into the styling. The two share the same sleek profile, although the roof on the coupe looks much better integrated (for obvious reasons). The frameless windows are indexed, meaning that they automatically open 0.25 inch when the doors are opened, and close again when the door is closed for a tight seal. From the rear, both cars feature narrow taillights and a sloping decklid that looks similar to the Toyota Solara coupe and convertible. We think it's an improvement over the blander styling of the sedan.

The Pontiac G6 is built in Michigan on GM's international Epsilon platform, from parts and ideas used on the Saab 9-3, Opel Vectra, and Chevrolet Malibu.

All G6 models use the long wheelbase version of the Epsilon platform (like the Malibu Maxx), which gives them 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.

These measures can be experienced in the smooth ride and sharp handling of the G6.
