More Hardcore Toyota Supra GRMN Spied at the 'Ring With BMW M Firepower

Believed to have been christened the Toyota Supra GRMN, it is a more track-focused variant of the series, which will take on the Nissan Z Nismo. A prototype of this model was recently caught undergoing testing at the Nurburgring, featuring camouflage at the front and rear to disguise some of the visual novelties.

If you look closely at its face, you will see a chunkier integrated apron complete with larger side blades. Save for the large wing mounted on the trunk lid, the back end is identical to the latest GR Supra. This applies to the sporty diffuser with an integrated brake light and cutouts for the dual exhaust tips, as well as to the bumper.

The tester featured a set of black Y-spoke alloys, just like the rest of the uncamouflaged exterior. It also had cross-drilled brake discs at both axles with red brake calipers that didn't have any branding on them. At first glance, it appears that it sits a bit closer to the ground, and that should be due to the re-tuned chassis, as it is expected to be stiffer than the regular lineup, a move that would improve its cornering ability.

Initial reports claimed that the Toyota Supra GRMN (name unconfirmed) might pack the same engine as the entry-level BMW M3 and M4. These feature a 3.0-liter twin-turbo straight-six that develops 473 hp (480 ps/353 kW) for 0-60 mph (0-97 kph) in 4.1 seconds. The Competition bumps the output to 503 hp (510 ps/375 kW), dropping the sprint time to 3.8 seconds. The xDrive AWD models are equally punchy and way faster, taking 3.4 seconds to reach 60 mph.

The latest unofficial data states that the Supra GRMN could share its engine with the BMW M2. This model enjoys 453 hp (459 ps/338 kW) and 406 pound-foot (550 Nm) of torque and needs 3.9 seconds from rest to 60 mph. Rumors also speak about a standard six-speed manual transmission in the upcoming high-end Supra, as well as an optional eight-speed auto. The best performance will be achieved with the latter, although the former unit will offer the most engaging drives.

Toyota will probably introduce it in the coming months, launching it as a 2025 model in the United States, where it will sit at the very top of the range. Given that the current 45th Anniversary grade starts at $65,275, we expect the Supra GRMN to be priced at more than $70,000, or slightly more. The BMW M2 has an MSRP of $63,200, and the M4 starts at $79,100.
