Chevrolet Corvette vs Toyota GR Supra: Specs Compared

Running cost over five years: at the EPA's 15,000-mile-a-year assumption the Toyota GR Supra burns about $2,700 of fuel annually against $3,250 for the Chevrolet Corvette. That $550 yearly gap compounds to roughly $2,750 over five years and $4,400 over eight — often more than the price difference between two trims of the same vehicle, and the single largest running-cost line item separating these two.

City and highway economy: the Toyota GR Supra leads in both cycles — 25 mpg city and 32 mpg highway against 17 and 29 mpg — so its fuel-efficiency advantage holds whether you commute in traffic or cover long highway miles.

Powertrain choice: the Chevrolet Corvette is recorded with 4 distinct engine configurations (SIDI & PFI, SIDI, SIDI & PFI; Hybrid), the Toyota GR Supra with 1 (SIDI). Across 49 recorded Chevrolet Corvette configurations and 17 for the Toyota GR Supra, the wider the engine spread the more the real-world fuel efficiency depends on which version you actually buy, so check the specific model year and drivetrain rather than the headline number.

Drivetrain and class: the Chevrolet Corvette is offered with Rear-Wheel Drive, All-Wheel Drive, the Toyota GR Supra with Rear-Wheel Drive. All-wheel drive typically costs one to two mpg combined against the same vehicle in front- or rear-wheel drive, which is worth remembering when the gap between these two is small. The EPA classes them as Two Seaters and Two Seaters respectively — the class drives the interior volume, cargo space and passenger space each one is measured against.

Tailpipe emissions: at their cleanest configurations the Toyota GR Supra emits 317 g/mile of CO2 versus 426 g/mile for the Chevrolet Corvette. Emissions track fuel consumption almost exactly, so the cleaner vehicle here is also the cheaper one to fuel.
