As the faster European model was not available in the United States and Canada during the first three years of its existence, a "Competition Group" option was created to allow North American customers to have an S model lookalike with front and rear spoilers, 16-inch flat disc wheels, sport seats, sport springs and Bilstein Shock Absorbers. Customers could specify paint and interior colours the same way as on a normal 928. Two cars were made in the late 1980 model year for U.S. with this option. The package was officially available in 1981 and 1982 model years and was canceled in 1983 when the S model became available for these markets. Many cars have had S model features added by subsequent owners, making original "Competition Group" cars difficult to distinguish without checking option codes.
