Chevrolet’s fastest crate engine ever
As the power behind the 2019 Corvette ZR1, the new supercharged 6.2L LT5 represents the pinnacle of Chevrolet’s performance: It’s the most powerful engine ever offered in a Chevy production vehicle.
An all-new, more efficient supercharger on the LT5 is based on the same effective four-lobe design as the LS9 and LT4 air compressors, but it is larger. At 2.65 liters of displacement, it is 64 percent larger than the LT4’s 1.7-liter compressor and pumps out more boost.
