The Acura NSX is a sports car produced between 1990 and 2005 by Honda. It is equipped with a mid-engine, rear-wheel drive layout, powered by an all-aluminium V6 engine featuring Honda's Variable Valve Timing and Lift Electronic Control (VTEC) system.

In 1984 Honda commissioned the Italian car designer Pininfarina to design the HP-X (Honda Pininfarina Xperimental), which had a mid-mounted C20A 2.0 L V6 configuration

After Honda decided to pursue the project its management informed its engineers that the new car would have to be as good as anything coming from Italy and Germany. The HP-X concept car evolved into the NS-X (New Sportscar eXperimental) prototype. The NS-X prototype and eventual production car. Honda intended the NS-X to meet or exceed the performance of the Ferrari 328, while offering targeted reliability and a lower price point. For this reason, the 2.0L V6 of the HP-X was abandoned and replaced with a more powerful 3.0L VTEC V6 engine. The NS-X was designed to showcase several Honda automotive technologies, many derived from its F1 motor-sports program.

For 1997 engine displacement increased from 3.0 L to 3.2 L using a thinner fiber-reinforced metal (FRM) cylinder liner. This revised 3.2 L engine gave it slightly more power: from 270 hp to 290 hp while torque increased from 210 lb·ft to 225 lb·ft (manual transmission only). The 4-speed automatic model still used the 3.0 L engine. Another big change was the adoption of the 6 -speed manual transmission. The new NSX 0-60 mph 4.5 secs. as recorded by Car and Driver in their August 1998 0-150-0 issue using a 3.2 & 1/4 mile 13.3 secs.
