2020 Acura NSX

The bespoke, twin-turbo system for the all-new engine offers a strong balance of high power with broad torque, high fuel efficiency and inherent packaging advantages. Through careful research and development, the Acura NSX engine design and engineering team determined that the ideal boost pressure is 105 kPa (1.05 bar or 15.23 psi).

Increasing the engine intake air pressure also increases the intake air temperature. A high‑volumetric flow air-to-air intercooler dramatically reduces intake air temperature, while increasing the density of the air intake charge for maximum power.

Each turbocharger uses an electronic wastegate for fast response and precise control. The single-scroll turbocharger design uses smaller turbos to reduce weight and improve packaging, while still meeting power and performance benchmarks.

In an engineering and design exercise drawn straight from Acura’s extensive racing experience, the cylinder heads fitted to the twin-turbocharged V6 are highly compact at a 75-degree angle. They include a compact valvetrain that uses swing arm-type valve actuators. The more compact head structure reduces the inertial weight of the valvetrain by 22 percent compared to a rocker arm-type design. This compact design together with the dry-sump lubrication was focused on lowering the vehicle’s center of gravity.

The cylinder heads utilize a three-piece water jacket for improved cooling efficiency and coolant flow control. The race-inspired cylinder head design also optimizes the swirling of intake air so that it mixes with fuel in a more ideal manner for improved combustion, improving efficiency and emissions performance.

Every custom-built Acura NSX embodies a rich history of precision craftsmanship, innovation, and quality. Made with US and globally-sourced parts, the new Acura NSX has the distinction of being the only supercar designed, developed and manufactured in the United States. The new Performance Manufacturing Center (PMC) in Marysville, Ohio, is the exclusive global manufacturing facility for the all-new Acura NSX.

Like the next-generation Acura NSX, the PMC is a clean-sheet design. Combining human craftsmanship and technological innovation, the PMC utilizes new approaches to vehicle construction, paint, assembly, and quality confirmation to deliver on the Acura brand DNA of Precision Crafted Performance. The PMC is optimized for low-volume production of high-performance specialty vehicles. Complementary production of the bespoke, twin-turbocharged V6 engine of the new Acura NSX is undertaken by a small group of master engine builders at Acura’s Anna, Ohio, engine plant.

Though the fundamental concepts for a New Sports eXperience remained clear and consistent throughout the development of the NSX, the technologies, and means by which the R&D team would realize their concept underwent a process of continual evolution. As a result, the PMC was designed around the unique, multi-material space frame and body panels of the all-new Acura NSX.
