Description: Lamborghini developed the QVX for the 1986 Group C championship season. One car was built, but lack of sponsorship caused it to miss the season. The QVX competed in only one race, the non-championship 1986 Southern Suns 500 km race at Kyalami in South Africa, driven by Tiff Needell. Despite the car finishing better than it started, sponsorship could not be found and the program was cancelled.
