The Chevrolet Corvette has a new-for-2027 LS6 V8, and it should be better in every way than the engine it replaces. The 6.7-liter mill has more displacement, more power, and more torque, to start. It's also an entirely new generation of engine, one that General Motors has touted as being vastly improved from the long-running 5.3-liter and 6.2-liter generation that came before. There is, however, one way that the new LS6 falls behind the old LT2.
