The Porsche 3512 did not perform well and Footwork had to switch back to the Ford engines.
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. Before the next race in France, the team switched to the Ford-Cosworth DFR 3.5 litre V8 engine, in a modified version of the car designated the FA12C.
