Shadow Racing Cars
Shadow Racing Cars was a Formula One and sports car racing team, founded and initially based in the United States although later Formula One operations were run from Britain. The team held an American licence from 1973 to 1975 and a British licence from 1976 to 1980, thus becoming the first constructor to officially change its nationality. Their only F1 victory was achieved as a British team.
History
1970–1972: Early years in CanAm series
The company was founded by Don Nichols in 1968 as Advanced Vehicle Systems; the cars were called Shadows, designed by Trevor Harris and entered under the Shadow Racing Inc. banner. The first Shadow, the Mk.I, was entered in the CanAm series with George Follmer and Vic Elford driving them. The Mk.1 featured an innovative design, using very small wheels for low drag and although the car was quick, it was not the most reliable car in the field
The team became more competitive the following year, replacing the Harris car with a Peter Bryant design owing some elements to his Ti22 'titanium car' with Jackie Oliver also arriving from this effort and finishing eighth in the CanAm championship. The team also found some financial backing in Universal Oil Products (UOP).
