In IMSA Supercar races, Consulier GTPs beat the Porsche 911 Turbo, Pontiac Firehawk, Saleen Mustang, Corvette ZR1, Lotus Espirt, Calloway Corvette, and Dodge Stealth. Mosler offered a $100,000 bounty to anyone who could race a street-legal production car around any United States racetrack faster than Mosler’s racing driver could send a Consulier GTP through; no one was able to get that cash, though some said the conditions were not 100% fair. The Consulier GTP was eventually banned by the IMSA in 1991 —as the Mosler Automotive web site says:
After dominating local SCCA races and winning the 24 hours of Nelson Ledges in 1990, Mosler Automotive entered the IMSA Supercar World with 4 silver Consulier Series II GTP's debuting at Lime Rock in 1991 with pole position and a victory. At just 2100 lbs, this 5 speed, 2.2 liter turbo with about 195 hp easily outpaced the other, more powerful but heavier cars, including Hurley Haywood in a factory Porsche Turbo, Boris Said in a Callaway Twin Turbo Corvette, Stu Haynor in a Firebird, and Jim Minnaker in a factory ZR1 Corvette. It was subsequently announced by IMSA that it was not in the best interests of the series for Consulier to win at which time they added a 300 lb weight penalty and finally banned the Consulier GTP from the series. The GTP remains an exceptional sports car and can still outpace most of today's production cars.
