Toyota has given its customer racing Supra GT4 a mid-life makeover.

    The GR Supra GT4 Evo has been fettled “in response to constructive customer feedback and the results of detailed evaluations”, and a focus has been placed on braking, the engine, and handling.

    On the braking front, the Evo features a new ABS system, while there are new KW dampers and revised anti-roll bars under the skin to help improve the car’s behaviour in the corners.

    Power still comes from a turbocharged 3.0-litre inline-six engine, but Toyota says there’s more power and an optimised torque curve. It also says cooling has been improved for 2023.

    In the road car, the BMW 3.0-litre inline-six in the Supra makes 285kW of power and 500Nm of torque. The ECU in the GT4 racer allows for up to 660Nm of torque, while the power output changes based on Balance of Performance rules.

    Power is still put to the road through a ZF automatic transmission, albeit one adapted for life on track. There’s a Drexler differential on the rear axle, and the engine breathes through an Akrapovic exhaust.

    Toyota says more than 50 examples of the GR Supra GT4 have raced since 2020, earning owners wins in 11 “national and international GT4 championships”.

    The Supra goes head-to-head with similarly adapted versions of the BMW M4, Porsche Cayman, and McLaren Artura in GT4-class races.
