Does the 2020 Corvette Stingray Make More Power Than Advertised?

Recent Dyno Tests Suggests So

The numbers for the Corvette’s naturally aspirated LT2 V8 engine makes 495 hp and 470 lb-ft of torque, according to General Motors. However, it’s now come to light that those numbers may be pretty darn conservative. MotorTrend recently had a 2020 Corvette Stingray to review and part of what the publication did was put the car on the dyno. It made way more power than advertised.

MotorTrend found that the car made 558 hp and 515 lb-ft of torque. That’s more than 60 hp and 45 lb-ft of torque more than what Chevy is advertising the car is putting out. What’s more, is that was the power measured at the wheels. When a car’s engine power is measured at the wheels you can expect about a 15 percent loss through the drivetrain. This means the C8’s engine likely makes 656 hp and 606 lb-ft of torque at the engine’s crank. That’s way more power than Chevy said this car makes.

After the dyno run, the guys at MotorTrend decided to do the test with a 2020 Ram 2500 pickup truck to make sure it wasn’t just their testing equipment. That truck put out the expected power numbers, so it’s not a mess up on MotorTrend’s end. The car they had is just that powerful. We’ll be interested to see if there are any other dyno tests out there and what they reveal.
