The NSX was designed by a team led by Chief Designer Masahito Nakano and Executive Chief Engineer Shigeru Uehara. It benefited from advanced aerodynamics and styling inspired by the F-16 fighter jet cockpit[4] as well as input, during the final development stages, from Formula OneWorld Champion Ayrton Senna.. The NSX was the first general production car to feature an all-aluminium semi-monocoque.[5] It was powered by an all-aluminium 3.0 L V6 engine, which featured Honda's VTEC (Variable Valve Timing and Lift Electronic Control) system developed in the 1980s, a 5-speed manual transmission, or starting in 1994 the SportShift 4-speed automatic transmission, also known as F-Matic, which allows the option of conventional automatic shifting or manually shifting with a fingertip shift lever on the steering column.
