Toyota GR GT hybrid twin-turbo V8 Unveiled With 641 HP and RWD Drivetrain

One of the most anticipated reveals of the year has finally happened. Toyota has unveiled the GR GT, and the production design confirms the company’s intent to create a potent, motorsports-bred road car. The Toyota GR GT hybrid twin-turbo V8 powertrain is the headline, built around a dry-sumped V8 engine making a preliminary 641 horsepower and 627 lb-ft of torque.

The production model, which is slated to arrive sometime around 2027, has been designed around three key criteria: a low center of gravity, low weight with high rigidity, and strong aerodynamic performance.

Here is a closer look at the innovative powertrain and performance focus.

Powertrain and Drivetrain Details

The power output is already impressive—beating the Porsche 911 Turbo S—but Toyota says the horsepower, torque, top speed, and weight figures could improve before the production car launches.

Component	Specification	Note
Engine	Dry-Sumped, Hot-Vee Twin-Turbo V8	Toyota’s first hot-vee design; heavily engineered for performance and emissions.
Output (Prelim.)	641 hp / 627 lb-ft	Feeds the rear wheels ahead of which sits an electric motor for torque fill.
Transmission	8-Speed Automatic Transaxle	Uses a wet-start clutch instead of a torque converter; positioned on the rear axle.
Weight	3,858 lbs or less (1,750 kg)	Lightweight goal achieved using all-aluminum frame and CFRP-and-aluminum body panels.
Top Speed	More than 199 mph	Expected to exceed 200 mph in final production form.

The hybrid component is focused purely on performance, with an electric motor positioned ahead of the transaxle to minimize lag and fill torque immediately. The mechanical limited-slip differential reinforces the focus on RWD purity.

Chassis Sculpted by Performance

The design of the Toyota GR GT hybrid twin-turbo V8 was decided in consultation with World Endurance Championship aerodynamicists first, with the all-new, all-aluminum frame layout decided long before stylists finalized the look. This ensures the car delivers on its track-ready potential.

Braking: Immense and repeatable stopping power is promised by Brembo carbon-ceramic discs.
Suspension: Double wishbone suspension is used at either end of the chassis with forged aluminum arms.
Interior Focus: The occupants sit low, having a “roughly identical” center of gravity to the car itself, promising exceptional driver feedback and visibility.

Toyota’s motorsports-bred philosophy means this new GR GT is built to be an exceptional driving machine and a fine halo for the brand, continuing the legacy once established by the LFA and 2000GT.
