All-new Corvette Stingray unveiled

General Motors reveals the most powerful base-model Corvette ever made. It's the most fuel-efficient, too.

The car's new aluminum structure is 99 pounds lighter than the steel frame underlying today's Corvette while it's also 57% stiffer. The body is made from composite materials, including carbon fiber in the hood and roof panels.

The new V8 engine uses advanced technologies to produce more power from less gasoline, GM says. Ultimately, thanks to lightweight construction, the Stingray has a better power-to-weight ratio than a Porsche 911 Carrera or an Audi R8, GM boasts.

Buyers will be able to choose from either a six-speed paddle-shifted automatic transmission or a seven speed manual. To help the driver shift gears, the Corvette offers "Active Rev Matching," which helps manage engine speeds for perfect shifts. It can be turned on or off using steering wheel paddles.
