Toyota Australia develops V8-powered GR Supra to race against Mustang, Camaro

Depending on the market, the Toyota GR Supra can be found with a choice of BMW engines, either a 2.0-liter inline-four cylinder engine (258 PS/400 Nm) or a 3.0-liter inline-six cylinder engine producing up to 387 PS/500 Nm of power.

However, for racing purposes, Toyota will sideline the German-made heart and prioritize a V8 engine to be fitted inside the GR Supra.

The V8-powered GR Supra race machine will compete in the Supercars Championship in Australia starting in 2026, with Toyota becoming the third manufacturer to join the competition against Ford Mustang and Chevrolet Camaro.

Reportedly, the V8-powered GR Supra race machine was internally developed by Toyota Australia in Altona to comply with the GEN3 Supercars Championship regulations.

The mentioned V8 engine already exists in high-performance Lexus vehicles such as the IS F, GS F, LC 500, and RC-F.

The naturally aspirated 5.0-liter aluminum heart (code 2UR-GSE) is capable of producing up to 481 PS/535 Nm of torque in the RC-F model, or 477 PS with a peak torque of 540 Nm in the LC 500 model.

Returning to the V8-powered GR Supra race machine, it will showcase the racing livery of the Walkinshaw Andretti United (WAU) team and will be piloted by drivers Chaz Mostert and Ryan Wood.

The WAU team previously raced under the Holden brand from 1987 to 2023, before switching to the Ford brand for three seasons, and will collaborate with Toyota starting in 2026.

Don’t celebrate too early, as this V8-powered GR Supra will only exist in racing form.

The road-going GR Supra will still continue with the inline-six cylinder engine offerings until its production ceases in the coming years.

However, before that, Toyota is reported to launch the Supra GRMN model with a retuned inline-six cylinder engine, a stiffer chassis, and improved aerodynamics.
