2014 Chevrolet Corvette Stingray on the Dyno
Edmunds has a 2014 Chevrolet Corvette in their test fleet and thought it would be a good idea to take the C7 down to MD Automotive in Westminster, California to see what kind of power the car is putting down at the wheels.
GM rates the Corvette’s flywheel output at 460 horsepower and 465 lb-ft of torque. Accounting for a 15 percent driveline loss, we’d expect the Corvette to generate 391 horsepower and 395 lb-ft of torque at the tires. What were Edmunds’ results? 411 horsepower and 407 lb-ft of torque to the road. We think GM is accurately rating its engines, which leads us to believe the Corvette Stingray has an efficient driveline — the calculations show an 11 to 12 percent driveline loss based on the official horsepower and torque figures.
Whether it’s an efficient driveline or a slightly underrated engine, welcome to the age where the base Corvette is now putting more than 400 ponies to the wheels. I think I like living in the C7 era.
