Although it's not due to officially arrive until 2015, Acura will debut a prototype version of its upcoming NSX supercar at the Mid-Ohio Sports Car Course on August 4. So wait, why Ohio? The facility is just a short distance away from Honda's North American R&D center that's in charge of the NSX development as well as the actual production facility where the new supercar will be built. The event is called the Honda Indy 200, and the running prototype will be an updated version of the NSX concept that debuted at Detroit last January.

Honda claims that the new prototype will be closer in styling and general proportions to the production version. In contrast to the concept, expect to see the test NSX to be a bit wider and longer along with revised air scoops and dams. What won't change is its powertrain: a Sport Hybrid Super Handling AWD system that features a mid-mounted V6 that'll be linked up with an electric motor driving the rear wheels via a seven-speed dual-clutch gearbox. A pair of electric motors will move the front wheels, allowing for electric torque vectoring. All told, power output will be in the 400 horsepower range.
