I just read that Chevrolet is building a 285 HP 4 cylinder engine for the Camero
The article mentions a turbo-charged 4 cylinder putting out 270HP. The high performance model produces 440HP. Same engine that’s used in the Corvette. It also has a stereo system that enables you to “enhance” the sound of the engine.
