The Acura NSX (marketed outside the USA as the Honda NSX), is a two-seat, mid-engine sports car sold under the Acura brand. The origins of the NSX trace back to 1984, with the HP-X (Honda Pininfarina eXperimental) concept, which was a mid-engined 3.0 L V6 engined rear wheel drive sports car. Honda committed to the project, with the intention of meeting or exceeding the performance of the then V8 engined Ferrari range, while offering reliability and a lower price point. The concept thus evolved and had its name changed to NS-X, which stood for "New", "Sportscar" "Unknown world" (the X was a reference to the mathematical symbol X, which stands for an unknown variable), although the production model was launched as the NSX. Two generations have been produced. The first one from model years 1991 to 2005 and the second from 2016 to 2022.
