Toyota GR Supra GT4 – straight to the race track
Toyota’s new GR Supra GT4 is scheduled to go on sale in the US in August. It is based on the production road car GR Supra that has been developed and produced by Toyota Motorsport GmbH (TMG).
A 3.0-litre inline six-cylinder engine with single twin-scroll turbocharger has been tuned to 320 kW (430 hp) with a 7-speed sports automatic transmission with paddle shifters 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 fibre composite, contributing to an overall weight of 1,350 kg (2,976 lb). Following the specification of the GR Supra road car, the front suspension will be MacPherson strut, and rear suspension will be multilink with KW dampers at the front and rear.
The braking system is enhanced using a dedicated brake calliper for racing, six-piston front and four-piston rear, while running on Pirelli tyres.
Safety will be a priority and 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 fibere instrumental panel with a display and steering wheel specifically designed for GT4 competition.
