If you brush up on your GR Supra lore, you might remember that, in 2018, Toyota had unveiled a racy spin on the Supra before they deigned to unveil the finished car to us. It was aptly named the ‘Racing Concept’, and now we get to see the car that it portending.
The Supra GT4 Concept will be shown to the public in the coming days at the Geneva Motor Show, and unsurprisingly has been engineered to conform to the FIA GT4 racing series regulations, begging the question as to why even to bother labelling it a concept in the first place if a) no one will be able to actually buy it for the road, and b) it’s spec-ready to be rolled out onto a GT4 grid.
Toyota and their Gazoo Racing division have clearly had their paws all over the Supra GT4, concept or not, taking a rather docile but subtly aggressive coupe and honing it down to a full-on racer.
The unnecessary internals have been removed in the same of weight-saving, and the same stripped-out approach has been applied to the cabin. In its place, the car has been given an FIA-standard fire extinguisher, an OMP race seat, a roll cage, and an endurance fuel tank with a quick-refuel system.
Elsewhere, the standard suspension components are swapped out for competition-spec springs, shocks absorbers, and anti-roll bars. A specially-designed front diffuser and rear wing combo add length transform its aerodynamic profile, though they may look like carbon fibre, are actually from a medley of natural materials such as hemp and flax.
Brembo racing brakes have been added all around, replacing the standard rotors and callipers, and topping it are a set of five-hole OZ racing wheels wearing Pirelli P Zero slicks that replace the stock set of Michelin Pilot Super Sports.
It’s a rather extensive list of upgrades in the name of performance, but in case you were wondering what Toyota had done to have the stock powertrain match up, sadly nothing of the sort has happened. This is perhaps the primary reason this car is still a ‘concept’.
Under the bonnet is pretty much the same engine as the standard 6-cylinder GR Supra. A motorsport-grade ECU is added to increase output by an unspecified amount, but the BMW-sourced 3.0-litre unit retains its twin-scroll turbocharger and, shockingly, the ZF 8-speed automatic transmission.
For reference, the previous-generation A80 Supra even spawned a Le Mans 24-Hour contender. The Supra LM-GT, using a modified V8, it raced in the premier GT1 class alongside all-time greats like the McLaren F1 GTR, Mercedes-Benz CLK GTR, and Porsche 911 GT1. We wonder if the all-new A90 will be able to take the Supra name back to that level.
