For months now, Honda was planning to use a naturally-aspirated V6 engine in the upcoming 2015 Honda NSX. This would then be mated to a three individual electric motors and Honda’s super handling all-wheel drive system.
However, on the eve of the Tokyo Motor Show 2013, Honda has released a mock-up of the 2015 Honda NSX’s powerplant and confirmed that it is actually a twin-turbocharged V6 engine! Additionally, there is word that Honda may increase the displacement of this engine from the original 3.5-liters up to 3.7-liters for that little bit of extra grunt! Unsurprisingly, this new engine will be completely unique to the upcoming NSX and could easily deliver enough power to rival cars such as the McLaren 12C and the Ferrari 458 Italia.
The engine is then set to be mounted longitudinally instead of transversely like original planned. This isn’t surprising considering rivals features a similar layout.
Joining the twin-turbocharged V6 engine will be three electric motors. In this system, one electric motor is mounted at each front wheel while the third is integrated into the engine and helps drive the rear wheels. These motors are powered by a lithium-ion battery recharged thanks to regenerative braking.
Mated to the awesome powertrain will be a dual-clutch transmission promising to have “more than six gears”. At this stage, it is most likely the 2015 Honda NSX will receive a seven-speed gearbox but an eight-speed could also be on the cards.
