The IMSA GT racing series had existed since 1971 when IMSA founder John Bishop started a racing series for GT vehicles. With the introduction of Group C in 1981, the IMSA also opened up to these racing prototypes . While GT vehicles continued to be driven at the same time, from 1981 special designs that were built exclusively for the GTP class were also used. The GTP vehicles complied with the technical regulations of Group C with the not insignificant difference that there were no fuel restrictions in the IMSA GTP series. In contrast to the races in the World Sports Car Championship , the teams could use as much gasoline as they wanted.
In 1981 the series consisted of no fewer than 22 races, not all championship races counting in the same championship class. Six races, the 45-minute race of Road Atlanta , the 45-minute race of Laguna Seca , the 45-minute race of Lime Rock , the 45-minute race of Sears Point , the 45-minute race of Portland and the second 45-minute race at Road Atlanta were only part of the GTU class. These races took place as 45-minute sprint races on race Sunday as part of the supporting program of the respective GTP races.
The series also included two traditional North American endurance races , the Sebring 12-hour race , which has been held since 1952 , and the Daytona 24-hour race . These two racing events and other long-distance races are also part of the World Sports Car Championship this year .
Manufacturer and driver ratings were announced. Porsche secured the GTP manufacturers' championship . Mazda was victorious in the GTU class , especially thanks to the success of the RX-7 .
In the overall standings, Brian Redman won the championship with the drivers , who won the standings with 213 points, clearly ahead of the American John Paul junior (130 points) and his compatriot John Fitzpatrick (111 points). Lee Mueller won the GTU class ahead of Walt Bohren and Logan Blackburn .
