C8 Corvette Will Get 27 mpg Highway, if Your Right Foot Lets You by Evan Williams January 29, 2020 Share Comments The Chevrolet Corvette has always offered impressive fuel economy to go along with the impressive performance, though not if you decide to want them both at the same time. Will moving the engine to the rear and dropping the manual gearbox change that longstanding equation? That looks like a no. Chevrolet revealed the C8’s fuel economy numbers ahead of the Rolex 24 at Daytona last weekend. Car and Driver reported the figures, that are an improvement over the outgoing 2019 car. 27 mpg highway, 15 in the city on the EPA cycle, says Chevrolet. That’s better than the 15/25 city/highway of the base C7, despite some extra weight, and it fares well against the new 911 Carrera’s 20/26. As long as you stay on the highway. The 6.2L V8 benefits from cylinder deactivation that can run the 495 hp engine on just four cylinders when you aren’t using all of the power. The extremely tall gear ratios for lower rpm on the highway also likely contribute to the better numbers.
