The PR01, designed for the 1993 season, had undergone none of the vital wind tunnel testing required to refine the car's aerodynamics, had seen only a few dozen miles of track testing and its Ilmor 3.5 L V10 engine was underpowered by 1994 standards.
O PR01, deseñado para a tempada de 1993, non se sometera a ningunha das probas no túnel do vento, algo vital para perfeccionar a aerodinámica do coche, só fixera unhas poucas ducias de km de probas na pista e o seu motor Ilmor 3.5 L V10 non tiña a potencia suficiente para os estándares de 1994.
