Acura’s sports-car racing program dates to 1986, the same year the Acura brand debuted as the luxury and performance division of American Honda Motor Co., Inc., and culminating in multiple championships in the previous two years in both DPi and GTD.  For 2021, Acura Motorsports will seek to repeat its DPi titles with the Acura ARX-05 prototype, battling Cadillac and Mazda; and field multiple Acura NSX GT-3 teams in a title defense against more than a half-dozen rival premium sports car manufacturers ranging from Ferrari to Mercedes-AMG to Lamborghini in GTD.
