Chevrolet re-engineers Corvette

Although the new C6 is shorter and narrower than its predecessor, engineers wanted “more power, more passion, more precision” for the two-seat sports car.

The storied history of the Chevrolet Corvette enters its next chapter with the introduction of the sixth-generation C6 for 2005. Sharing many components with Cadillac's XLR roadster, the new model replaces the outgoing 1997-2004 C5 this fall, with the first variants being a coupe and convertible. The C6 is a significant 5 in (125 mm) shorter and 1 in (25 mm) narrower than the previous model, its length of 174.6 in (4435 mm) and width of 72.6 in (1844 mm) placing it closer in size to one of its primary competitors: the Porsche 911.

The shorter overall vehicle length was enabled in front by shortening of the hydroformed rails by 2.4 in (61 mm) and of bumper beam thickness by 0.63 in (16 mm). Previously roll-formed, the new beam is made from two C-channels of high-strength, 180-ksi (1.24-GPa) steel seam-welded together. Rear length was reduced by more effective positioning of energy-absorbing foam and by shortening of the rear fascia and bumper structure. Better packaging and a 1.1-in (28-mm) wheelbase extension helps to maintain interior room and class-leading cargo space.
