The FA12 finally debuted at the San Marino Grand Prix, where Caffi failed to qualify the new car (Alboreto still had an A11C). For the following Monaco Grand Prix both drivers had FA12s - Caffi once again failed to qualify and Alboreto retired from the race. Stefan Johansson replaced Caffi at the Canadian Grand Prix after Caffi sustained injuries in a road accident; this time both drivers qualified but both also retired from the race. The Mexican Grand Prix was the last appearance of the Porsche engine; Johansson failed to qualify and Alboreto again retired from the race.
