 The 1991 season marked the introduction of the FIA’s new, and controversial, 3.5 Litre Formula which replaced the highly successful Group C category that had been used in the World Sports Car Championship since 1982.However, due to a small number of entries in the new 3.5 litre formula heavily penalised Group C cars were allowed participate in the newly created C2 category for the 1991 season but Jaguar participated in the new formula.To comply with the new regulations Jaguar produced an all-new car, the XJR-14.
