General Motors today released the first details about the engine that will power the redesigned 2014 Chevrolet Corvette.
The iconic American sports car will get a new V8 engine with a displacement of 6.2 liters, 450 lb.-ft. of torque (610 Nm) and at least 450 horsepower. Designated LT1, the engine 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 as well, including the redesigned 2014 Chevrolet Silverado and GMC Sierra pickup trucks. According to officials, the LT1 will enable the sports car to accelerate from zero to 60 miles per hour in under four seconds.
GM has also put an emphasis on fuel consumption, with the new engine expected to be “the most fuel-efficient 450-horsepower engine on the market,” according to the automaker. The engine will have cylinder deactivation technology, which allows the vehicle to stop using four cylinders of displacement temporarily to improve fuel economy.
According to Jordan Lee, chief engineer and program manager for GM’s small-block engines, the new V8 unit 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.
