GM Introduces New Gen 5 Small-Block V-8 for 2014 Corvette
In the Corvette, the direct-injected, 6.2-liter LT1 V-8 is rated to generate an estimated 450 horsepower and 450 lb.-ft. of torque, and Chevrolet claims the new 2014 'Vette will accelerate to 60 mph in less than 4 seconds while getting 26 mpg on the highway. Active Fuel Management is standard, shutting half of the Gen 5 small-block V-8 engine's cylinders off when cruising on the highway or coasting down a hill or to a stop.
GM says the LT1's Advanced Combustion System is the "most intensely analyzed, developed, and optimized" in history, and the story of its development is to become subject of a Society of Automotive Engineers (SAE) paper. According to Chevrolet, the company spent significant time developing an optimum combination of direct fuel injection, continuous variable valve timing, and Active Fuel Management to arrive at the right balance of horsepower, torque and fuel economy. Premium fuel is recommended for the new LT1, but is not required, according to GM.
Additional details about the new 6.2-liter V-8 will be available in the weeks to come, as GM prepares to officially introduce the redesigned 2014 Silverado and Sierra in December, and then unveil the 2014 Corvette in January.
