Toyota is evaluating a track-oriented, road-legal GR GT prototype in Germany.
The aggressive test mule sports a swan-neck rear wing along with fender vents.
Additional modifications encompass an extended front splitter and bumper canards.

Toyota's highly anticipated supercar made its debut last December, yet the mid-engine V8 model is not scheduled to reach customers until next year. Meanwhile, fresh spy footage shows prototypes back at the Nurburgring for final development work. The regular GR GT is not the only version accumulating laps at the demanding circuit, as observers have also captured a more aggressive variant.

Initial impressions might suggest the track-only GR GT3 has been brought out, but that is not accurate. The disguised prototype displays a license plate, confirming it remains a street-legal car. Nevertheless, it incorporates several elements inspired by the race version. An updated aerodynamic kit features a front splitter that extends farther than the standard design. At the rear, the swan-neck wing immediately signals this is no ordinary model.

Although Toyota applied camouflage to most of the vehicle, certain details were left visible on purpose. The front fenders now include carbon-fiber louvers similar to those on the Porsche 911 GT3 RS, and front canards are visible at the bumper edges. These new parts will likely be available as an optional package, or Toyota may introduce a distinct GR GT variant. A limited-run GRMN edition is not expected so soon after launch.

The Nordschleife footage captures both GR GT versions running together, highlighting their differences clearly. The more extreme model is expected to retain the hybrid system, as the prototype still shows the required yellow sticker for electrified vehicles during track testing. This marking assists marshals and responders in identifying high-voltage systems after any incident.

Performance packages of this type usually focus on aerodynamics rather than added power. Consequently, the enhanced GR GT may keep the same combined output of 641 horsepower and 627 pound-feet from its twin-turbo 4.0-liter V8 and electric motor. These numbers apply to test cars and could increase in the final production model.

It remains uncertain whether engineers will reduce weight further with additional carbon fiber. Even with such measures, any savings are unlikely to be substantial. Toyota projects the standard GR GT will weigh no more than 3,853 pounds, a competitive figure for a hybrid V8 supercar.

The GR GT introduces Toyota's first all-aluminum body structure, which will also underpin another vehicle. Lexus plans to revive the LFA nameplate in 2027 as an electric supercar on the same lightweight platform. Whether its panels will incorporate aluminum and carbon-fiber-reinforced plastic like the GR GT is still unknown. The electric version will almost certainly weigh more regardless.

What do you think?

Motor1's Take: Toyota aims to challenge German rivals with the GR GT on their home ground. Meanwhile, Mercedes-AMG is preparing a new Black Series model featuring similarly dramatic aerodynamic upgrades and a strong race-car-on-the-road character.

With emissions rules growing stricter globally, these could represent the final V8-powered supercars.
