By the start of 1991, the team had been taken over by the Japanese Footwork concern and renamed accordingly, and had also secured a deal to run Porsche V12 engines, replacing the Fords. However, the team's car for that season, the FA12, had to be redesigned when it was discovered that the large Porsche engine, the 3512, could not fit into it. The team therefore modified the A11B into the A11C to accommodate this engine, and used it in the first two races, as well as at San Marino after Alboreto destroyed his redesigned FA12 during practice. From these five attempts, the ageing car qualified only once (Alboreto in the United States), before being finally retired.
