Next Corvette Will Be Powered by Small, High-Revving Turbo V-8 - Yahoo! Autos: "GM has approved the use of a very European-style V-8 that will be only slightly larger than 3 liters in displacement.  The engine will be an overhead-cam, rather than traditional overhead-valve design, using a dry sump oil system that’s particularly well suited to high-performance road courses rather than straight-line acceleration. The engine is expected to feature a narrow 80.5 mm bore and a long stroke, more like a Ferrari or Lamborghini powertrain than the approach used for traditional Motor City metal.

A very senior GM executive also confirmed that the new engine will be turbocharged, which will help yield a broad torque curve and maximum performance under a variety of driving conditions. The engine is expected to deliver in excess of 400 horsepower, which means a specific output in the range of 125 horsepower per liter. That’s the sort of number that would help the next-generation Vette stack up well against the likes of a Porsche 911 or Lamborghini Gallardo."
