Everyone makes mistakes. Sometimes multiple people make mistakes, and that seems to be the case with a recent article by Motor Trend claiming that the pre-production 2020 Chevrolet Corvette Z51 the magazine dyno’d put 558 horsepower and 515 pound-feet of torque to the wheels. This, the magazine estimated, translates into a naturally aspirated 6.2-liter V8 making 656 hp and 606 lb-ft of torque at the crankshaft. Eyebrows have been raised considering how much higher those power figures are than Chevy’s own SAE-certified numbers of 495 hp and 470 lb-ft of torque.
My best guess is that the dyno operator made a mistake – then Motor Trend made another by taking the numbers at face value.
