2025 Toyota GRMN Supra spied with new ‘swan neck’ wing

The 2025 Toyota GRMN Supra is edging closer to reality, with a prototype caught on camera testing at Germany’s famous Nurburgring circuit.

Reports claim the high-performance, track-oriented Toyota is planned to adopt the GRMN badge – which translates to Gazoo Racing Meister of the Nurburgring – and will sit above the current GR Supra in the range.

Since 2020, rumours out of Japan of a GRMN Supra have suggested the model – which is based on the same vehicle architecture as the BMW Z4 convertible – will be powered by the same 3.0-litre twin-turbo inline six-cylinder engine found in the BMW M3 and M4.

While some unconfirmed reports have the GRMN Supra putting out as much as 405kW, others have claimed the GRMN Supra could use a de-tuned version of the BMW M engine – like the 338kW version found in the M2, rather than the M3 Competition’s 375kW tune.

However, the latest information from Japan’s Best Car magazine – which is known for having reliable sources within Toyota – claims the GRMN Supra will instead continue to use the single-turbo engine from the standard GR Supra, but tuned to produce in excess of 300kW.

In standard guise, the GR Supra produces 285kW and 500Nm from its 3.0-litre single-turbo six-cylinder engine.

The unconfirmed report from Best Car also claims Toyota will use a seven-speed dual-clutch automatic transmission (DCT) in the GRMN – which it implies will be sourced from BMW – marking the first time such a gearbox has been fitted to a model from the Japanese car giant.

It would be odd for Toyota to fit this gearbox given BMW no longer sells a car that uses it – and all of its M models now use the eight-speed auto fitted to the regular GR Supra.

This latest prototype appears to use a new carbon-fibre ‘swan neck’ style rear spoiler – found on high-performance Porsche models like the GT3, GT3 RS, and GT4 RS – which helps to reduce turbulence and improve downforce.

A front spoiler with dual carbon-fibre canards and a deeper lip is expected to provide greater downforce at track speeds, while the vehicle also appears to have larger brakes and ride on lower suspension.

These digital illustrations from Best Car (above) provide an idea of what we can expect when the vehicle when the vehicle makes its debut.

To improve performance, a weight-reduction program has also been employed for the GRMN – with the bonnet, roof, and interior components reportedly being made from carbon-fibre.

A set of lightweight alloy wheels shod in Michelin Pilot Sport Cup 2 tyres is also expected to feature on the GRMN Supra.

Toyota’s GRMN badge is typically reserved for limited-edition variants that offer greater performance than its sporty GR-branded models.

Another option is the Morizo badge – the racing pseudonym of Toyota president Akio Toyoda – which was used on a lightweight GR Corolla hot hatch special edition, and was recently trademarked by the company, suggesting its use on more future models.
