Honda Motor Co. has unveiled a mock-up of the powertrain for its next NSX during a media event at its global r&d center in Japan. Using the mock-up as a basis, the powertrain for the redesigned all-wheel-drive NSX features a V-6 engine with twin turbos as part of what the carmaker dubbed as Sport Hybrid-All Wheel Drive system.
The SH-AWD system employs a three-motor hybrid system to redirect power, while a vehicle is making a turn, from the inner wheel to the outer wheel to enhance handling and performance. Each of the front wheels has one electric motor. The third electric motor is integrated into the engine as a motor-generator.
Honda officials said that the new V-6 would not necessarily be larger than the 3.5-liter V-6 fitted on the Acura RLX. The new V-6 will be paired with a dual-clutch transmission, although it has yet to be determined how many gears it would have.
Honda currently has a seven-speed dual-clutch gearbox and is planning to introduce an eight-speed transmission. The lithium ion battery pack will be placed in front of the engine that is mounted longitudinally instead of the transverse setup typical in most front-wheel-drive vehicles.
