2025 Toyota GRMN Supra caught on video

Toyota is about to up the performance of its Supra sports car in a big way.

The automaker has been spotted testing a camouflaged prototype at the Nürburgring and on some of the German racetrack’s surrounding roads, and it’s thought to be for a track-focused GRMN grade.

GRMN is the range-topping option for road cars developed by Toyota’s Gazoo Racing motorsports department. It stands for “Gazoo Racing Masters of Nürburgring,” and cars classified as GRMNs can be compared to top offerings from the likes of Subaru’s STI and Mercedes-Benz’s AMG divisions.

The first GRMN model was a GRMN 86 launched in 2016. It was followed a few years later by a GRMN Yaris. While neither of these cars were offered in the U.S., the GRMN Supra is expected to make it here late this year or early next as a 2025 model.

The latest prototype in the spy footage shows new details like a larger wing. The test vehicle also appears to sport new flics on the front fascia and an extended splitter. A new hood also appears to be present, judging by the camouflage gear. Most of the modifications are aimed at increasing downforce.

There will likely also be chassis modifications, similar to what Toyota has developed for its Supra GT4 customer race car. Some of those modifications may include a track-tuned suspension with adjustable dampers and stiffer anti-roll bars, uprated brakes, and performance tires. The prototype is wearing Michelin’s Pilot Sport Cup 2 tires.

Reduced weight is also possible.

Toyota hasn’t even mentioned plans for a more hardcore Supra, but rumors point to the car coming with a version of the twin-turbocharged 3.0-liter inline-6 found in BMW’s M3 and M4 Competition models. The engine is rated at 473 hp when paired with rear-wheel drive in the base M3 and M4, and this may be the rating Toyota uses for the Supra range-topper.

The Supra is a twin under the skin with the BMW Z4 and currently offers 2.0-liter turbo-4 and 3.0-liter turbocharged inline-6 engines shared with the BMW convertible. The peak power at present is 382 hp, meaning the GRMN Supra may deliver a substantial leap in performance.

Stay tuned for updates as development continues.
