The Honda NSX will be powered by a twin-turbocharged V6 engine, instead of the naturally aspirated V6 originally planned, according to internet reports.
The U-turn was revealed when the Japanese car manufacturer demonstrated a mock-up twin-turbo V6 unit during a media event on the eve of the Tokyo motor show.
Unlike the original NSX, the new model will have its powerplant mounted longitudinally instead of transversely. Two of the Honda NSX's perceived rivals - the McLaren 12C and Ferrari 458 Italia - both have their engines mounted longitudinally.
The engine, which will be completely unique to the NSX, is planned to be mated to Honda's SH-AWD (super handling all-wheel drive) system that uses a three-motor (one for each front wheel and a third one integrated into the engine as a motor generator) hybrid layout.
Putting the finishing touches to the powertrain will be a new dual-clutch transmission, but Honda officials are yet to finalise the number of ratios.
