2014 Chevrolet Corvette Over-Delivers with 455 HP

Optional exhaust bumps that to 460.

by on May.29, 2013

The 2014 Chevrolet Corvette Stingray is the most powerful "base" 'Vette ever.

When it comes to the 2014 Chevrolet Corvette Stingray, General Motors has decided to under-promise and over-deliver.

The maker had originally said it expected the new sports car, known to fans as the C7, to make an already impressive 450 horsepower once final numbers were calculated. In fact, the Corvette will come in at 455 hp, and with the optional high-performance exhaust package, that gets bumped up to 460 ponies.

Your Performance News Source!

That will make the Chevrolet Corvette the most powerful base car in the long and colorful story of the ‘Vette which made its debut six decades ago. But power alone doesn’t tell the entire story of the new 2-seater which has been completely remade for 2014 and which GM now hopes will help it compete more directly with the European brands that have dominated the global sports car market.

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.
