The GR Supra GT4 is based on the GR Supra – TOYOTA GAZOO Racing’s first-ever global model.

A three-liter in-line six-cylinder engine with single twin-scroll turbocharger has been tuned to 320kW^*（430hp）with a 7-speed sports automatic transmission with paddle shift and the mechanical limited slip differential driving the rear wheels. An Akrapovič exhaust system will be fitted and Ravenol will provide first-fill lubricants. The front splitter and rear wing are made of natural fiber composite, contributing to an overall weight of 1,350kg,

The braking system is enhanced through the use of a dedicated brake calliper for racing, six-piston front and four-piston rear.

The GR Supra GT4 will be installed with a high-strength roll cage on the lightweight steel body, and an FIA-standard racing seat with six-point harness. The interior will feature a carbon fiber instrumental panel with a display and steering wheel specifically designed for GT4 competition.

The GR Supra GT4 is available in the Skip Barber Race Team which competes in GT World Challenge Americas GT4 America.
