Coloni C4

The Coloni C4 is a Formula One car designed by for the Coloni team for use in the 1991 Formula One season, although it never qualified for a race and was the slowest car in the field. An evolution of the C4 was also briefly used by the Andrea Moda team in 1992 as the Andrea Moda C4B. The C4B made its only appearance at the season-opening South African Grand Prix, at which Andrea Moda Formula was excluded for not having paid the registration fee for the championship and for not having entered a car they had constructed themselves. The C4B was replaced by the S921 at the next Grand Prix in Mexico.
