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.
Michelle Christensen, NSX exterior design project leader, remarked that the new NSX is a product of the so-called 'Interwoven Dynamic' design, allowing the vehicle to become an effective fusion of the form of exotic sports cars and the function of supercars.
As designed, the body of new NSX is featured with classic low and wide proportions, modern surfaces, aggressive front end as well as rear lights paying tribute to the original model. It comes with the signature side intake and floating C-pillar that guides airflow for cooling the NSX’s mid-mounted engine as well as direct airflow over the rear deck to generate more downforce. Compared to the NSX Concept unveiled in 2012, the new Acura NSX is longer by three inches, wider by an inch, and has a cab that is slightly made forward, allowing the supercar to better accommodate its new longitudinally mounted twin-turbo V6 and its nine-speed DCT.
Acura made certain that each element of the exterior of the new NSX allows for complete airflow management -- to generate more downforce to ensure better stability and to better cool the systems of the vehicle. To ensure this, the new NSX was made to undergo extensive aerodynamic testing at the carmaker’s state-of-the-art wind tunnel in Raymond, Ohio. This process also allowed the carmaker to implement a number of tweaks as needed. As a result, the final production NSX features new front fender vents, modified hood vents, modified side air intakes as well as an optimized deck spoiler.
