Now that the new Toyota Supra (officially known as the GR Supra) has been launched, Toyota is showing how it can be further enhanced for competition with a racing concept version. The GR Supra GT4 Concept has been designed to provide an affordable and competitive entry into grassroots motorsport (‘affordable’ might not be what applicable in Malaysia).

It is engineered to comply with international motorsport regulations for GT4 series races – one of the fastest growing categories with international and national competitions across the globe. A GT4 racing version can offer even greater performance, building on the superior handling and agility from the production car’s front-engine, rear-drive layout, its rigid lightweight body and perfectly balanced chassis.

Performance boost
The Supra GT4 Concept gains a performance boost for its turbocharged 3.0-litre inline-6 petrol engine through a retuned engine management system and motorsport-grade driveshafts and limited slip differential.

It also retains the production car’s MacPherson strut front and multilink rear suspension setup but is fitted with competition springs, dampers and anti-roll bars. High-performance Brembo brakes provide the necessary braking power for racing.

Better downforce and airflow
Visually, the GT4 concept is instantly recognisable as a GR Supra albeit slightly longer and lower giving the two-door coupe an even more muscular aesthetic. At the front, a specially designed diffuser has been added, which together with a rear wing, improves airflow around the chassis, reduces drag and optimises downforce.

These aerodynamic additions have been made from natural fibre composites using materials such as hemp and flax – rather than traditional carbonfibre – in order to reduce the impact on the environment.

Inside the stripped-out cabin, the GR Supra GT4 Concept features a high-strength roll cage, and competition-standard fire extinguisher and OMP racing seat. A fast refuelling system with a motorsport-spec fuel tank also replaces the standard fuel tank.

Toyota GAZOO Racing will evaluate interest from potential customers before deciding on any further development of the GR Supra GT4 Concept.
