 Mazda, having accomplished their goal of winning the 24 Hours of Le Mans in 1991 with their famed rotary engine, were left without the ability to use their rotary engine anymore in 1992.Since Mazda entered sportscar racing mostly to push their rotary designs, Mazda decided to continue on into 1992 for advancement of the overall brand, but with a less ambitious development programme.Mazdaspeed bought customer versions of the Jaguar XJR-14 and slightly modified them into the Mazda MXR-01 while the engines were customer Judd GV V10s.
