2025 Toyota GRMN Supra Spied Testing at the ‘Ring

• What appears to be the 2025 Toyota GRMN Supra has been spied testing at the Nürburgring racetrack in Germany.
• Wearing camouflage reserved for Gazoo Racing (GR) models, the Supra prototype has upgraded aero bits and beefier brakes versus regular models.
• Reports of a track-focused GRMN Supra date back to 2020, with more recent rumors suggesting it’ll adopt the BMW M4’s 473-hp twin-turbo 3.0-liter straight-six.

It looks like Toyota is preparing to launch a new Supra variant that’s purpose-built to lap what’s arguably the world’s greatest racetrack as quickly as possible. Our spy photographer recently captured images of a partially camouflaged prototype racing around Germany’s legendary Nürburgring Nordschleife. We suspect it’s the 2025 Toyota GRMN Supra.

GRMN?

While most Supra fans are likely familiar with Toyota’s Gazoo Racing (GR) division, not everyone may have heard of GRMN. That acronym stands for “Gazoo Racing tuned by the Meister of the Nürburgring.” The latter is a nickname for Toyota’s late chief test driver, Hiromu Naruse.

While catching a Supra testing at the ‘Ring doesn’t mean it’s definitely a GRMN model, rumors dating back to 2020 have kept us on the lookout for such a machine. With the Supra adding a manual transmission for the 2023 model year—another rumor that turned out to be true—the next logical step in the A90-generation’s evolution is a track-focused version.

GRMN Supra Hardware

From what we can see, the Supra test mule features a revised front lip and canards. Out back, there’s a prominent rear wing. A cursory glance suggests it’s similar to the spoiler seen on the 2024 Supra 45th Anniversary Edition, however, a closer look reveals the one on the prototype has lightweight mounting brackets and different tips.

Other obvious details that reveal that the car at the Nürburgring isn’t a run-of-the-mill Supra are upgraded brakes and what appears to be a lowered ride height. The GRMN variant will likely have a revised suspension that’s lower and stiffer to help improve the coupe’s already sharp handling.

Unlike the regular GR Supra, the prototype looks to have larger brake calipers too, along with what are clearly cross-drilled rotors. The spy photos also tell us to expect a set of lighter wheels mounted on ultra-grippy Michelin Pilot Sport Cup 2 tires.

Supra+M4 Engine=GRMN

The biggest mystery about the GRMN Supra is what will be under the hood. Like the rest of the lineup, we know it’ll be a BMW-sourced engine. It’ll also likely be pulled from one of the Bavarian automaker’s M cars, perhaps the 473-hp twin-turbocharged 3.0-liter straight-six that motivates the M3 and M4.

There’s a good chance the Toyota winds up with a detuned version of that same mill, like the one that powers the 453-hp BMW M2. What do all of those engines have in common? They’re offered with a manual transmission. The same can’t be said of the 543-hp powerplant found on the bonkers M3 CS and M4 CSL, which we don’t think is a candidate for the GRMN Supra anyways. Of course, only time will tell.
