The engine for the next Corvette has been confirmed as a 449bhp 6.2-litre V8. The heavily upgraded unit, codenamed LT1, will deliver 610Nm of torque and be capable of powering the Corvette from 0-62mph in less than four seconds.
"The Corvette LT1 represents the most significant redesign in the Small Block's nearly 60-year history – building on its legacy to make one of the world's best engines even better," said Sam Winegarden, vice president, Global Powertrain Engineering.
The engine is the first of a new generation of small block V8s, which feature direct injection, GM’s active fuel management system (which shuts down four of the eight cylinders under light throttle loads) and variable valve timing.
Thanks to the fuel-saving tech, Chevrolet claims that the new Corvette will be the most fuel-efficient ever, returning a claimed average of 31.4mpg.
The new Corvette will make its debut at the Detroit Motor Show in January 2013, before going on sale here later that year priced from around £55,000.
A convertible version will arrive a year later and should cost from around £62,000, making it slightly more expensive, but considerably faster and only a little less fuel efficient than the entry-level 3.0-litre V6-powered Jaguar F-Type.
