It was just last week that a nearly stock NSX trounced competition decisively to win the Time Attack 2 class at the Pikes Peak International Hill Climb race. Now, Acura has released the first official images of its NSX GT3 racecar with which it will campaign in the North American racing season in 2017. Photographed while undergoing developmental testing at the GingerMan Raceway in South Haven, Michigan, the extreme NSX, which is slated for homologation as an FIA GT3 class racecar later this year, sports exposed, lightweight, carbon fibre bodywork. “Building on the very solid foundation of the production NSX, we're making steady progress in our development and looking forward to campaigning the GT3 racecar next year,” says Art St. Cyr, president of Honda Performance Development.
Predictably, being developed as a GT3 racer, the Acura NSX GT3 features aggressive bodywork and aero addenda, including a monstrous deck wing spoiler, massive front and rear underbody diffusers and larger vent on the bonnet. Under the bonnet, there’s the same 3.5-litre twin-turbo V6 as the road-going version of the supercar, which although doesn’t have the hybrid system, uses the same block, heads, valvetrain, crankshaft, pistons, as well as the dry sump lubrication system as the road car. However, there’s one major change in the drivetrain, which is the use of a six-speed sequential gearbox to transfer power to the rear wheels, in place of the nine-speed dual-clutch transmission found in the production car.
The Acura NSX GT3 is built by Honda’s Performance Manufacturing Centre in Ohio, which is also the exclusive production facility for the new NSX road car. While testing is going on now in circuits across the US, initial development of the GT3 racecar was conducted by Honda’s Japan race engineering arm which did testing on various race tracks in Europe and Japan.
