If there was a 4WD version of your model in the range, you could use it. Either as 4WD or with the drive to the front wheels disconnected and it became a RWD car. Vauxhall tried this first in 1990 with a second Cavalier. It was said to be "the best balanced racing car I've ever driven" by either Chris Hodgetts or John Cleland, I can't remember, but it lacked power among other things.
Ford didn't enter until midway through 1993 because they had to redesign the car as a front wheel drive one. They found they lost too much power when sending it to the rear wheels, as well as increased weight which would have made it uncompetitive. However in 1995, the German works Mondeo team did run full 4WD cars, but they never really had any success. Charlie Cox had a 4WD hatchback built when he recovered from his accident, but I can't remember if they ever ran it in 4WD form or just FWD.
