2025 Toyota GRMN Supra Testing with Exhaust Sound

The 2025 Toyota GRMN Supra, an exciting addition to Toyota’s sports car lineup, has been generating significant buzz in the automotive world. This high-performance variant, short for “Gazoo Racing Masters of the Nurburgring,” showcases Toyota’s dedication to enhancing the Supra’s capabilities, particularly in track-focused environments.

Spy images and testing activities at the Nürburgring Nordschleife hint at substantial upgrades over the regular models. The Supra GRMN is expected to feature a sportier aero package, including a more aggressive front bumper with large intakes, canards, a splitter, reworked side skirts, and a distinctive fixed spoiler at the rear. These modifications are not just cosmetic but are designed to improve aerodynamics and downforce, crucial for high-speed stability and cornering on the racetrack.

Underneath its striking exterior, the Supra GRMN is anticipated to boast enhanced performance hardware. Rumors suggest that it could be equipped with BMW’s formidable S58 engine, a 473-hp twin-turbo 3.0-liter straight-six, known for its use in the M2, M3, and M4. However, it’s plausible that Toyota might opt for a slightly detuned version, similar to the 453-hp engine powering the BMW M2, to maintain a unique character for the Supra GRMN.

In addition to the engine upgrade, the Supra GRMN is likely to feature a retuned suspension setup with bigger brakes and lightweight wheels. These improvements aim to sharpen the handling and braking performance, essential for a car with track aspirations. The use of cross-drilled rotors and Michelin Pilot Sport Cup 2 tires in the prototype suggests a focus on high-performance driving conditions.

The GRMN badge, reflecting Toyota’s commitment to high-performance vehicles, pays homage to their late chief test driver, Hiromu Naruse. This model aims to embody his spirit of pushing the boundaries of automotive engineering and driving pleasure.

Overall, the 2025 Toyota GRMN Supra represents a significant step up from the regular Supra models. With its enhanced aerodynamics, upgraded engine, and track-focused improvements, it promises to deliver an exhilarating driving experience, both on the road and on the racetrack. As with any upcoming model, exact specifications and performance figures will be clearer closer to its launch date.
