NSX Engineers Reveal Its Hidden Secrets


Honda shows its cards at SAE 2015.

Claiming its desire to "inspire the imagination" of enthusiasts, Honda has allowed its engineers to share new technical detailsabout the 2016 NSX at the SAE 2015 World Congress and Exhibition. As we knew,the heart of the car is its Sport-Hybrid AWD power unit, a twin-turbo V6 matedto a 9-speed DCT. An electric motor applies torque directly to thecrankshaft, delivering immediate power to the rear wheels. The DCT's shaftdesign, engineers say, lowers weight and keeps the center masscloser to the driver.

Next, theNSX team revealed its multi-material space frame design, an aluminumintensive frame that makes the NSX the most rigid in its competitive set. "Itoffers the lowest weight and best rigidity, precision and hybrid powertrainpackaging capability of any design." A world first, the NSX's Ablationcasting offers "the ductility and energy absorption characteristics ofextruded material". Furthermore, the company's A-Pillar has been built fromhigh-strength three-dimensionally formed steel, offering improved visibility,shape and crush performance. The team kept a "human centered"concept, optimizing the car's performance as experienced by the driver throughthe body.

The NSX's total airflow management is a thermal aerodynamic package that cools the V6 through three radiators, while the 9-speed DCT uses two heat exchangers. Aerodynamic balance and downforce are achieved by minimizing drag, utilizing vents, 6 rear vortices, a lower rear diffuser and narrower fins at the front. The AWD's "next-generation torque vectoring" offers "more electric power, delivered more directly, managing more internal combustion power". Dynamic torque vectoring at low speeds and zero delay acceleration will be reached with the electric motors' Super Handling. The car also features a double-wishbone suspension, a double lower control arm front suspension and variable gear ratio steering.
