The Horsepower Boom
Twenty years ago, most Corvette engines produced about half as much power as the 2015 Z06. So how did the Vette's V-8 figures double? The Z06 uses a supercharger, for one, which pumps oxygen into the engine, letting it burn more fuel. "Boost devices like that are smaller, more efficient, and more durable now than they once were," says GM's Damico. Likewise, the use of stiffer, lighter-weight parts — like titanium intake valves — reduces mass and allows the new engine to run at a higher rpm. So are we at "peak horsepower"? Perhaps not. "Let's just say that the V-8's trajectory hasn't flattened out yet," says Damico. "You're gonna continue to be amazed."
