Light Makes Right – 60 Years of Corvette Weight Reduction Tech
Today, many cars use composite body panels that are lightweight and durable, but late-model Corvettes continued to lead the way with innovation in materials, design, and “added lightness” – the C5′s hydroformed steel frame rails, floor sections made with a sandwich of materials around a balsa wood core, and the C5 Z06′s titanium exhaust combined with the all-aluminum LS powerplant to make this generation actually lighter than the C4 that preceded it. The current C6 Z06 took things a step farther with aluminum replacing steel in the frame, magnesium in the roof structure, and carbon fiber fenders.
“Corvette has never been focused on an exclusive material – be it aluminum, carbon fiber, or fiberglass,” said Corvette Executive Chief Engineer Tadge Juechter. “Instead, we are constantly looking for the best materials structure, powertrain, and chassis to improve the performance of Corvette.”
