The new Chevrolet Corvette C8.R race car has just debuted at the Rolex 24 at Daytona, the USA. The 2020 model favorably compares against the outgoing 2019 Corvette C7 by its fuel economy.
The C7’s EPA-rated figures are 15 mpg (city) / 25 mpg (highway). The new C8 has 15/27 mpg and impressive driving range of 490 miles on the highway, although it is heavier than the predecessor.
For comparison: the rivaling 2020 Porsche 911 is rated 20/26 mpg. A significantly pricier McLaren 720S consumes 22 mpg on the highway according to EPA.
Sure enough, the new Corvette‘s cylinder deactivation system contributes to fuel economy, when the 6.2-liter 8-cylinder engine turns into a V4 by shutting down the valve operation at low loads.
