Those hoping for a return to the original NSX’s philosophy of a simple but effective powertrain and rear-wheel-drive may have been heartened this week. Acura revealed an NSX GT3 in New York this week that eschewed a hybrid or AWD system. The bad news is, it’s not street legal.
The NSX GT3 race car is currently undergoing testing and will be homologated as an FIA GT3-class competition vehicle this fall. Though it looks similar to a road-going NSX, it sports revised bodywork, including an underbody diffuser and enlarged hood vents for more efficient cooling. Oh, and there’s also a massive downforce-generating wing on the back.
The NSX GT3 tosses the road car’s three-electric motor hybrid system. Power comes purely from a 3.5-liter twin-turbo V6 sharing most major components — including the block, heads, valvetrain, pistons, crankshaft and oil sump system — with the road-going version. Acura declined to mention how much power it will make, but by itself the road car’s engine make 500 horsepower. Normally, the hybrid electric system adds 73. The removal of the two electric motors, one at each wheel, also eliminates the AWD drivetrain. The engine will be mated to a 6-speed sequential transmission.
Initial development of the NSX GT3 was conducted by the company’s Japan race engineering arm with testing on race circuits in Europe and Japan. Like the road cars, the race cars will also be built at Acura’s Performance Manufacturing Center in Ohio. The NSX GT3 will hit the tarmac for the 2017 season.
