Most four-wheel drive layouts are front-engined and are derivatives of earlier front-engined, two-wheel drive designs. Probably the best known user of this layout is Audi with its quattro four wheel drive system, which first appeared in the 1980 Audi Quattro road car. This layout had been tried before in the early 1900s and later with the Ferguson P99 F1 Racing car in the 1960s and in the Jensen Motors built Jensen Intercepter| which used Fergusons Four-wheel drive system.
