If you go back further to Group C, the Falcon was also a two-door coupe, except that it had a 5.8L V8 as opposed to the 5.3L V12 in the Jaguar.

We'll never know how the Jaguar would have done in Group C trim as opposed to the Commodores and Falcons, Uncle Tom stalled the car on the line and was firmly thumped in the rear.
