E-Ray Corvette Will Come as a Widebody Wearing 345-Sized Rear All-Weather Michelin Tires


E-Ray Corvette Will Come as a Widebody Wearing 345-Sized Rear All-Weather Michelin Tires

Isn’t it amazing how much we apparently already know about a car General Motors hasn’t even acknowledged exists yet?

The latest intel on the upcoming hybrid Corvette believed to be named the E-Ray comes to us today from GM Authority, who are reporting the size of the tires to be used on the car. The website also is predicting when the E-Ray will make its debut, too.

Up front on the new hybrid Corvette will be 275/30R20 tires, while 345/25R21s will anchor the back. Like the base Stingray, these tires will be Michelin Pilot Sport All Season 4 run-flats that can be used year-round and provide gobs of grip in both dry and wet conditions. GM Authority also predicts E-Ray customers will be able to add even-stickier Michelin Pilot Sport Cup 2 tires made for ultimate dry traction performance suitable for track day driving with long tread life, even under high-performance driving conditions.

For reference, the base and the Z51 Stingrays run the same size Michelins (245/35R19 in front and 305/30R20 in back) – but with the Pilot Sport All Season 4 on the base and the Pilot Sport 4S summer-only high-performance model best suited for dry conditions on the Z51.

GM Authority believes the E-Ray will make its debut a few months after the already-confirmed Z06 that will be officially unveiled by Chevrolet later this year.

The website believe the larger tires on the E-Ray indicate it will be using the same widebody layout as the 2023 Z06, but the E-Ray will apparently be the first Corvette ever to feature all-wheel drive necessary to put its predicted 600 horsepower and 575 lb-ft of torque to the ground. In addition to the base Stingray’s 495-horsepower LT2 gasoline engine that will drive the rear wheels, the E-Ray is also expected to have four 1.94-kWh batteries and a front-mounted electric drive unit for the front wheels.

  1. Will it have an external charging port for the front drive batteries? Many Corvettes sit in the garage for extended periods and that kills the batteries.
