Tonawanda plant to build GM's most powerful engine

Tonawanda News — The General Motors Tonawanda Engine Plant will produce the company's most powerful engine ever, a press release from the company states.

The Corvette Z06 engine will be built at the plant in the fall, and is one of a few engines that can produce more than 600 horsepower. The Corvette’s LT4 supercharged 6.2L V-8 engine is certified at 650-horsepower.

“The LT4 Small Block sets a new benchmark for power and torque at GM,” GM Powertrain Vice President Steve Kiefer said. “The engine also puts the new Corvette Z06 on par with the most powerful supercars offered in America, while delivering performance with impeccable manners that make it suitable for daily driving.”

The engine will be assembled at the Tonawanda plant as well as the Performance Build Center at GM’s Bowling Green Assembly Plant in Ohio. The engine has 29 percent more horsepower than the previous generation's model and 40 percent more peak torque.

“Torque is the pulling power of an engine and the LT4’s abundance of it at every rpm in the engine’s speed range helps the 2015 Corvette Z06 accelerate quicker and respond nearly instantaneously,” Jordan Lee, chief engineer for Small Block engines, said. “It’s the very definition of power on demand.”

The Corvette Z06 will go on sale in the fourth quarter of 2014. The car will have an eight-speed automatic option, as well as the conventional manual transmission.
