 Nova Engineering retained their R91CK, while Team Le Mans would leave the series.Team Take One would take up their place with a former factory R91CP.For the 1992 season, the championship was actually divided into two classes, with the older Nissans running in C1, while cars which conformed with the 1992 World Sportscar Championship 3.5L engine specifications would run in C. This meant that although Nissan would be competing against newer and faster cars, they would still be able to compete for victories against competitors in their class.
