519:. Chassis 691 (Rebadged as #192) debuted at the 1992 Grand Prix of Miami where it broke the track record by four seconds. Without a major upgrade to the suspension and with the car unable to deal with the high G loads of U.S circuits, the XJR-14 was unable to beat the latest challengers from Toyota and Nissan, forced to finish third in the championship with only two victories. Jaguar continued to use the three updated 1991 chassis throughout the season.

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.

The abandonment of the Group C fuel consumption regulations meant a change in aerodynamic design philosophy. Coupled that with vastly different packaging requirements for a small, light, normally aspirated engine meant that concerns over drag became a secondary requirement to downforce. The new

It was not until midway through the season that the Jaguar met its match through
Peugeot's new 905B. This meant a hard fight with the new and quickly improving Peugeot squad for the rest of the season, but Jaguar was able to hold on and secure the manufacturers title with 3 victories.

After 1991, Jaguar decided not to continue in Group C, believing that they had spent enough time in Group C and the instability of rules recently in the World
Sportscar Championship. Opting against further development of the XJR-16, TWR sent the XJR-14 to the United States for the

Formula One power plant. Developed by Geoff
Goddard, and most notably used by the Benetton Formula One team, the now Jaguar-badged HB was detuned to around 11,500 rpm and 650 bhp (compared to the 13,000 rpm and 700 bhp F1 spec) with aims at enhancing reliability.

491:. Only the opening race went Peugeot's way, but that was seen more as a result of luck than the 905's competitiveness. The fact that Jaguar already had a race proven engine certainly helped the team’s cause, but the rest of the car was far superior to its rivals.

which entered in the C2 class. Although the XJR-12s did not manage to win, Jaguar's decision not to run the untested XJR-14 was vindicated by the fact that
Peugeot's 905 failed to finish the race. Mercedes also withdrew its C291 in favour of its older
466:-derived JV6 engine, in order to comply with the new rules the two turbochargers would need to be removed. Naturally this wasn't a realistic option, nor was it ever considered, given the design compromises of not using a bespoke engine.
502:, Jaguar initially entered two XJR-14s but later decided that the XJR-14 would not be capable of finishing the distance due to unknowns in the development of the Cosworth HB to last 24 hours. Jaguar instead decided to enter three older

Three chassis were built and used for 1991: #591, #691, and #791. In the early part of the 1991 World
Sportscar Championship season the XJR-14 was in a league of its own, totally outclassing its rivals and in particular the
