The PR01 was driven by Paul Belmondo and Bertrand Gachot for the whole season, with the test drivers being Oliver Gavin and Giovanni Lavaggi.

Pacific lacked a single main sponsor for the 1994 season and the car ran with many different names on the sidepods, including Ursus.

During 1991, Reynard concluded that the project would not be ready, so the entire program, including the Enstone factory, was sold to Benetton.

The naturally aspirated 3.5 L V10 engine from Ilmor was of a two-year-old design - underpowered by 1994 standards; it was not upgraded.

The team even considered withdrawing from the championship in order to work on their PR02 chassis, however if this happened, they would have had to pay a substantial fine.
