There is now another racing version of the Honda NSX, in addition to the NSX GT3 – the NSX-GT. Where the NSX GT3 is powered by a 3.5 litre, twin-turbocharged V6 engine derived from the road car, the NSX-GT uses a 2.0 litre, turbocharged, direct-injection four-cylinder engine as per Super GT regulations. Like the NSX GT3, the NSX-GT is rear-wheel drive and internal combustion engine only.

It may be a lot smaller with two fewer cylinders compared to the GT3, but it’s still a potent engine, with power expected to be at least 590 hp. The GT3 race car is already well endowed with aerodynamic aids, and the Japan-bound racer here takes things further still. In addition to the dive planes on either side of the front bumper, the front splitter is even larger, while rows of vents feature on the extended wheel arches.

Around the back, the production NSX tail light assembly appears to be carried over, while the massive rear wing and diffuser dominate the airflow proceedings around the rear of the NSX-GT. With a driver onboard but without fuel, the NSX-GT is said to weigh 1,049 kg. The next NSX-GT will go head to head with the likes of the Lexus LC GT500 and a revised, racing version of the Nissan GT-R.
