When the original Honda NSX was first introduced, it shook the supercar world to its core and caused the new Ferrari 348 to lose its relevance almost immediately. Approximately 25 years later, the 2015 Acura NSX is determined to repeat history once again. This time, the sights are aimed at the Ferrari 458 Italia.

According to Acura, the upcoming 2015 Acura NSX will challenge the benchmark Ferrari V8 with a radical twin-turbo V6 hybrid drivetrain. Unlike the 60-degree V6 found in the mainstream Honda vehicles, the NSX is a 90-degree V6 that features a dry-sump oil system for an even lower center of gravity. Unlike the transversely mounted V6 in the original NSX, the twin-turbo V6 in the new 2015 Acura NSX is longitudinally mounted. We suspect the layout is better for packaging the NSX's hybrid components.

The displacement of the V6 NSX engine has not been announced, but industry observers expect the engine to be no more than 4 liters. Combined with three electric motors, the twin-turbo hybrid 2015 Acura NSX is expected to produce more than 500 hp. A 7-speed gearbox transfer power to all four wheels.

However, technology and power output alone will not be enough to position the Acura NSX against the sensual Ferrari 458. If you really want to cause a stir, you go topless. Enter the Acura NSX Roadster.

"We are looking at the convertible," said Principal Designer Jun Goto, "but we have a long way to go with it." According to Goto, the NSX convertible will not be unveiled until as late as two years after the NSX coupe officially hits the market. In fact, Acura engineers have yet to decide whether the NSX will be a foldable hardtop or a soft top. It will not, however, be a targa top like the original NSX.
