Next Corvette to Target Euro-Supercar Fans With Small, High-Revving Turbo V8

“We have to target a very different sort of buyer.”

by on May.25, 2011

Coming at you: GM will adopt a European-style, small-block, turbocharged V8 for the next-gen Corvette.

This exclusive report (c) TheDetroitBureau.com.  It has been updated to reflect additional details.

Anxious to attract the sort of high-performance buyers increasingly drawn to European sports cars from the likes of Porsche, Ferrari and Lamborghini, General Motors is planning some major changes for the next-generation Chevrolet Corvette – starting with a high-revving, small-displacement powertrain, that will substitute for the big V8s traditionally found under the hood of the Chevy 2-seater.

TheDetroitBureau.com has learned that GM has approved the use of a very European-style V8 that will be only slightly larger than 3 liters in displacement.  The engine will be of 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.

The Inside Story!

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-gen Vette stack up well against the likes of a Porsche 911 or Lamborghini Gallardo.
