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 the British base in Northampton. 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, at the 1977 Austrian Grand Prix, was achieved as a British team.The Shadow name was revived by Bernardo Manfrè in 2020 as an Italian car tuning and luxury brand. The revived Shadow brand currently competes in NASCAR Whelen Euro Series as the Swiss-based 42 Racing team, currently fielding the No. 17 Shadow DNM8 for Manfrè and the No. 42 Shadow DNM8 for Luigi Ferrara and Francesco Garisto.
