Toyota GR Corolla gets track-ready GRMN treatment, now a 2-seater

In Toyota's hierarchy of high-performance cars, the GRMN (Gazoo Racing, tuned by the Meister of the Nürburgring) sits at the very top, representing the most focused expression of the company's motorsport know-how.

Only a handful of models have been bestowed the coveted designation, including the GRMN Yaris that arrived in 2022. Now, the GR Corolla is the latest model to receive the GRMN treatment, making it the ultimate hot hatch in Toyota's line-up.

Known officially as the GRMN Corolla, it benefits from a host of enhancements centred around improved aerodynamics, reduced weight and a bespoke chassis setup, drawing on lessons learned from Toyota's Super Taikyu racing programme as well as extensive testing at the Nürburgring.

Starting from the outside, the GRMN Corolla is immediately recognisable through its more aggressive body kit, which incorporates a raft of carbon-fibre components such as a new bonnet, fender ducts, front side spoilers and a rear wing.

These are not merely cosmetic additions, as they were developed using knowledge gained from the hydrogen engine-powered GR Corolla that competes in the Super Taikyu Series. The rear wing, which features a five-stage angle adjustment mechanism, was fine-tuned at the Nürburgring.

As for the suspension, the regular GR Corolla's twin-tube shock absorbers have been replaced with a monotube setup featuring rebound springs, improving inner-wheel traction during cornering while also enhancing high-speed stability. Toyota says the dampers were tuned with millimetre-level precision to achieve the desired balance.

The changes result in a ride height that is 5 mm lower than before. Complementing this are Michelin Pilot Sport Cup 2 tyres measuring 245/40 ZR18, which are 10 mm wider than those fitted to the standard model.

The quest for sharper handling does not stop there, as Toyota has also reworked the electric power steering for improved response under high lateral loads, while the GR-Four all-wheel-drive system has been recalibrated to provide more optimal rear torque distribution during straight-line driving and enhanced stability at the initial stage of steering input at high speeds.

On top of that, the application of structural adhesive has been extended by 13.9 metres to a total of 32.7 metres, further increasing body rigidity.

The GRMN Corolla retains the familiar G16E-GTS 1.6-litre turbocharged three-cylinder engine, although Toyota has managed to extract an additional 15 Nm of torque, bringing the total to 415 Nm, while power output remains unchanged at 305 PS. Toyota says the extra torque is available between 3,600 and 4,800 rpm, improving acceleration when exiting corners.

To ensure durability under sustained high-stress conditions, the company has also fitted an intercooler spray system, complementing the cool-air duct introduced on the 2026 GR Corolla.

Unlike the standard GR Corolla, which is available with either a six-speed intelligent Manual Transmission (iMT) or an eight-speed automatic, the GRMN version is offered exclusively with the former.

While the torque increase may appear modest on paper, the GRMN Corolla is expected to deliver stronger overall performance thanks to its improved power-to-weight ratio. Weighing 1,450 kg, it is 30 kg lighter than the manual GR Corolla and 50 kg lighter than the automatic version, thanks to the use of carbon-fibre components and the removal of the rear seats.

Beyond the missing rear bench, the GRMN Corolla gains full bucket front seats inspired by the driving position used in Super Taikyu race cars. Toyota says the driver's seat has been shaped to facilitate clutch operation, while the glass fibre-reinforced polymer (GFRP) construction helps reduce weight.

Not only that, there is also an exclusive flocked instrument panel and flocked A-pillars designed to help the driver maintain focus. In case you've forgotten you're in something special, the cabin also features carbon-fibre trim on the passenger side of the dashboard, instrument panel padding bearing Morizo's signature, Alumite Red accents on the door trim and shift knob, as well as a serial-number plate.

In addition to the GRMN Corolla, Toyota is also developing the GR Corolla Morizo RR. While it sits within the same GR family, the Morizo RR takes a different approach by prioritising everyday usability over extreme track focus, retaining a five-seat layout and being equipped with the automatic transmission. This makes it a more approachable option for enthusiasts who want performance without sacrificing practicality.

According to Toyota, sales of the GRMN Corolla are scheduled to begin next year, with availability focused primarily on Japan, North America and Australia. Production numbers have yet to be announced, although the model is expected to be built in limited quantities, much like the GRMN Yaris that was capped at 500 units. Pricing also remains under wraps, but expect a significant premium over the standard GR Corolla.
