The Lamborghini Miura is a sports car produced by Italian automaker Lamborghini between 1966 and 1973. The car pioneered the mid-engined two-seat layout, the standard for high-performance sports and supercars since. When released, it was the fastest production road car made. The Miura was originally conceived by Lamborghini's engineering team, which designed the car in its spare time against the wishes of company founder Ferruccio Lamborghini, who preferred powerful yet sedate grand touring cars over the race car-derived machines produced by local rival Ferrari. The Miura's rolling chassis was presented at the 1965 Turin auto show, and the prototype P400 debuted at the 1966 Geneva show. It received stellar receptions from showgoers and the motoring press alike, each impressed by Marcello Gandini's sleek styling and the car's revolutionary mid-engine design. Lamborghini's flagship, the Miura received periodic updates and remained in production until 1973. A year later the extreme Countach entered the automaker's lineup, amid tumultuous financial times for the company. The P400S Miura, also known as the Miura S, made its introduction at the Turin Motorshow in November 1968, where the original chassis had been introduced three years earlier. It was slightly revised from the P400, with the addition of power windows, bright chrome trim around external windows and headlights, new overhead inline console with new rocker switches, engine intake manifolds made 2 mm larger, different camshaft profiles, and notched trunk end panels (allowing for slightly more luggage space). Engine changes were reportedly good for an additional 20 PS (15 kW; 20 hp). Other revisions were limited to creature comforts, such as a locking glovebox lid, a reversed position of the cigarette lighter and windshield wiper switch, and single release handles for front and rear body sections. Other interior improvements included the addition of power windows and optional air conditioning.
