Advanced Sports Package: Design Philosophy for Ultimate Handling

Aiming to achieve optimum handling, the 2017 Acura NSX's "advanced sports package" is a unique design philosophy that focuses on the strategic placement of key vehicle systems. This includes the Sport Hybrid power unit and major hybrid components like the Intelligent Power Unit, which contains a lithium-ion battery pack. The design is centered around lowering the center of gravity, centralizing vehicle mass, and achieving desired weight distribution.

The bespoke all-aluminum twin-turbocharged V6 engine boasts a 75 degree cylinder bank angle, dry sump lubrication system, and compact valvetrain, all optimized for a low center of gravity and compact design. In the same vein, the purpose-built 9DCT utilizes a new design with the clutch and differential located side by side in a common housing, and a parallel shaft gear set arrangement, all contributing to the reduction in powertrain length.

The Intelligent Power Unit features a new, compact lithium-ion battery pack with high power and energy density and a "caseless" design to reduce mass. This unit is situated in front of the rear bulkhead, while the twin fuel tanks are placed behind the rear bulkhead and in front of the engine.

The NSX's design also aims for minimal overhangs and a small footprint, while maintaining comfortable cockpit headroom even for 95th percentile male drivers.

Aerodynamics: "Total Airflow Management"

The Acura NSX's design and development team adopted a "total airflow management" approach to balance the superlative aerodynamics expected from a next-generation supercar and the efficient thermal management needed for its hybrid power unit. Efficient cooling is achieved by managing airflow through 10 heat exchangers strategically located to leverage airflow from the front grill area, side air intakes, and through the engine compartment.

Moreover, the NSX manages the air flowing through and around the body while maintaining increased stability through appropriately distributed downforce. In fact, the new NSX is known for its stability at high speeds, providing an enhanced driving experience with unprecedented balance and confidence.

Through extensive research and development, the NSX aerodynamics team determined that a 3-to-1 downforce ratio—placing three times as much downforce at the rear of the vehicle relative to the front—would provide optimal downforce distribution for high-performance driving.

Employing extensive use of computational fluid dynamic (CFD) simulations and testing of a 40-percent scale model in the company's advanced wind tunnel facility in Ohio, the team was able to refine various body shapes, intake and exhaust vents, and vehicle strakes to reduce aerodynamic drag, create downforce, maximize cooling, and efficiently exhaust unwanted heat. These developments were consistently verified at the company's full-scale, moving ground plane wind tunnel in Sakura, Japan.

NSX Cockpit: Driver-Centric Ergonomics

The NSX cockpit presents an outstanding example of ergonomic design, combining intuitive controls and layouts with carefully chosen materials and padding in the sports seats, steering wheel, and center console. The result is a driver-centric environment that elevates the driving experience.

Developed through extensive testing and pressure mapping measurements, the seats in the new NSX are designed to offer supreme comfort and support, providing the necessary lateral and fore/aft support needed in a high-performance vehicle. The selected seat materials, including leather and Alcantara, combine dynamic driving support and comfort with easy ingress and egress.

The center console and controls have been designed to minimize distractions, enabling the driver to focus on the most important function—driving. This design philosophy is aptly named the "simple sports interface."

This system highlights the unique capabilities of the NSX's Sport Hybrid power unit in customizing the driving experience and dynamic performance according to the driver's needs and the driving environment.

Design, Development, and Manufacturing

The design and development of the next-generation NSX involved a global team of engineers and designers. The development concept underwent continual improvement and evolution throughout its roughly four-year development process. Notably, the engine design evolved from a transverse-mounted, normally aspirated V6 to an all-new bespoke twin-turbocharged, longitudinally-mounted V6 engine. This change had profound implications for every aspect of the NSX design, especially in the areas of package, cooling systems, and aerodynamics.

The NSX was tested and tuned on streets and race circuits around the world, including Virginia International Raceway, the famed Nürburgring in Germany, and at Honda's own Takasu test circuit in Hokkaido, Japan.

The NSX is manufactured at the new Performance Manufacturing Center (PMC) in Marysville, Ohio using domestic and globally-sourced parts. The PMC was designed to innovate new means and methods of producing low-volume specialty cars and to realize challenging new ideas for next-generation craftsmanship and quality established by the NSX manufacturing team. Among its many innovative processes is the world's first use of all-robotic MIG welding for the construction of the NSX's aluminum space frame.

The NSX's bespoke twin-turbocharged V6 engine is meticulously hand-assembled by expert technicians at the company's engine plant in Anna, Ohio, using techniques and processes benchmarked against the company's world-class race engineering programs. Each engine is bench-tested and broken in to the equivalent of 150 miles of service. The NSX's 9-speed dual clutch transmission, Direct Drive Motor, and engine are machine balanced and assembled at the Anna Engine Plant. The Twin Motor Unit (TMU) and other hybrid system components are built in Japan and sent directly to the Performance Manufacturing Center for fitment in the NSX.
