The Toyota GR Supra GT4 Concept will make its debut at the 2019 Geneva motor show, which gets under way this week.
Developed by Gazoo Racing, Toyota's European racing arm, with the FIA's GT4 racing series in mind, the Supra GT4 Concept rides on race-ready five-hole OZ 18-inch wheels.
The suspension also features competition-grade shocks, springs, and anti-roll bars, while the brakes have been sourced from Brembo.
The car has been fitted with a unique front diffuser and rear wing, which are constructed from hemp and flax materials rather than carbon-fibre to reduce the vehicle's environmental impact.
Power comes from the road car's 3.0-litre turbocharged straight-six engine. While it's still coupled to an automatic transmission, it has received a new ECU, wiring looms, and race-spec drive shafts and limited-slip differential.
While power and torque figures are not yet available, Toyota says the GT4 Concept does have a motorsport-ready fuel tank and race-style fast refuelling system.
Naturally the cabin has been stripped back to the bare minimum, with an FIA-compliant roll cage, fire extinguisher and bucket seat from OPA fitted.
The company says it "will evaluate the interest shown by potential customers in the Supra GT4 Concept before deciding on future development of the vehicle".
