Claim: The Porsche 3512 did not perform well and Footwork had to switch back to the Ford engines.
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. 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.
