GM unveils redesigned V8 engine for 2014 Corvette
Wed Oct 24, 2012 9:48am EDT
(Reuters) – General Motors Co said the redesigned 2014 Chevrolet Corvette that goes on sale next year will get a new 450-horsepower V8 engine.
The engine, designated LT1, displaces 6.2 liters and is the fifth generation of GM’s “small block” V8 engine family.
Versions of the LT1 are expected to be used in other GM products, officials said, including the automaker’s redesigned 2014 Chevrolet Silverado and GMC Sierra pickup trucks.
In the new Corvette, the LT1 will enable the sports car to accelerate from zero to 60 miles per hour in four seconds.
The LT1 will be “the most fuel-efficient 450-horsepower engine on the market,” GM said at a media briefing Wednesday.
The cylinder-deactivation technology will allow the Corvette to operate like a 3.1-liter 4-cylinder engine for “much of the operating time,” Juechter said.
“The more time you can spend in that operating mode, the better the fuel efficiency,” he said. “That’s the reason why we’re staying at 6.2 liters.”
Lee said the Corvette engine is “extremely compact” and “power dense” at 25.3 inches tall. It will use direct-injection technology with a compression ratio of 11.5:1, which improves fuel economy and performance.
“It is indeed an all-new engine,” he said.
