Claim: The Footwork FA12, which was intended to start the season, finally debuted at the San Marino Grand Prix,  a Formula One motor race held at Imola on 28 April 1991.
Evidence: The FA12 was intended to start the season, but the new Porsche 3512 engine was so large and bulky that the car had to be re-designed to install it properly, so a 1990-based car called the A11C was used for the first three race meetings. The FA12 finally debuted at the San Marino Grand Prix, where Caffi failed to qualify the new car (Alboreto still had an A11C). The 1991 San Marino Grand Prix was a Formula One motor race held at Imola on 28 April 1991.
