Is The 2020 Corvette C8 Making 650 Horsepower. Motor Trend took a 2020 Corvette C8 to a dyno machine to find the truth behind the incredible performance of the new Corvette and the results are simply unbelievable.

The magazine wanted to run a real-mpg test, but the testing company didn’t have equipment to deal with square tailpipes. So MT took the red Z51 coupe to its local, oft-used dyno for what would turn out to be six confounding runs. The numbers after the first run in fifth gear run: 558 horsepower and 515 pound-feet of torque. At the wheels.

Assuming parasitic driveline losses of 15% would mean the Corvette was putting out around 656 hp and 606 lb-ft at the crank. If we assume a 10% loss, the crank figures come to about 620 hp and 570 lb-ft. Either set represents a shocking surplus over the Corvette’s official rating 495 hp and 470 lb-ft. And the official rating isn’t Chevy putting its best foot forward — GM pays to have the Society of Automotive Engineers (SAE) certify its output figures using the SAE’s strict protocols.
