Honda commissioned Pininfarina to design the Honda HP-X in 1984. The HP-X stood for Honda Pininfarina Xperimental. The Pininfarina Company has continued to provide styling consultancy services to numerous manufactures over the years. The styling on the Honda HP-X got the ball rolling as far as styling was concerned for the NSX.
The Honda HP-X had a mid-mounted (behind the two-seater cockpit) 2.0 L V6 configuration that was powered by a Honda Formula 2 V8 that had a very low Cd of 0.25.
The HP-X was styled in a way that was intended to show the automotive world was Honda was truly capable of. A single-piece Perspex canopy acted as a windscreen, side windows and roofs and also acted as the only form of entry. The roof lifts off jet-fighter style to allow passengers in.Jessica Donaldson
