Racing history

The Lotec 681 was developed by Lotec in 1981, and featured a 3.5-litre BMW M88 straight-six engine. It debuted at the fourth round of the 1981 Interserie season, held at the Nürburgring; Kurt Lotterschmid ran the car, finishing third overall, and second in the Sports 2000+ category.[1] Lotterschmid ran the car again in the next round, at Most, but, whilst running in second place and with a lap to go, the BMW engine blew; although he was classified second for the first race,[2] he was unable to compete in the second,[3] preventing him from featuring in the overall classification.[4] The series returned to the Nürburgring for the next round, and Lotterschmid took fourth overall, and third in his class.[5] Lotterschmid finished the season by retiring from the final race, held at Zolder.[6] Despite being reasonably successful, the car would not run again, having been made all-but-redundant by rule changes,[7] and Lotec introduced the Group C-spec M1C for 1982.
