Toyota racing fans will have a lot more to cheer for next year as the Toyota GR Supra GT4 takes to tracks all over the world. Sales will start in Europe from March 2020 and expand to North America in August, and to Japan/Asia in October. The Toyota GR Supra GT4 is based on the GR Supra road car (read our launch report at this link). It was developed and will be produced by Toyota Motorsport GmbH in Germany. In GT4 racing the Supra will be up against the likes of the Porsche Cayman GT4 and the Lotus Evora GT4.
The standard car’s 3,0-litre inline six-cylinder engine with single twin-scroll turbocharger has been tuned to 320 kW (Balance of Performance dependent), up from 250 kW from the road car. Peak torque jumps from 500 to 650 N.m. In part, the power upgrade comes from a freer-breathing Akrapovic exhaust system and motorsport-spec Magneti Marelli ECU. The motor is mated with a seven-speed sports automatic transmission that drives the rear wheels through a mechanical limited-slip differential.

As it is based on its road car namesake the Toyota GR Supra GT4 has the same suspension layouts front and rear. MacPherson struts are responsible up front while the rear suspension is via multi-links. KW dampers are used on both ends. The braking system is upgraded to six-piston Brembo calipers up front and four-piston Brembos on the rear; steel discs measure 390 mm and 355 mm, respectively. Lightweight OZ alloys are coupled with Pirelli slicks.
The Toyota GR Supra GT4 will come from the factory with a high-strength roll cage, and an FIA-approved racing seat with six-point harness. The interior will feature generous lashings of carbon fibre used on the instrument panel. A display and steering wheel specifically designed for GT4 competition will be employed.
