The Lamborghini Countach QVX, occasionally referred to as the Lamborghini QVX, was a short-lived Group C sports racing car built in 1985. It was not built or designed by the Lamborghini factory, but instead used a Spice Engineering-built chassis and an engine derived from the Lamborghini Countach's V12. Lamborghini's British importer commissioned the car. Financial issues restricted it to one race, despite numerous entries in 1986 and a handful in 1987, but its one race showed the car had potential.
