Have a search for the launch photos of the Mk2 ST in 2005 and you will find they were all 3-door cars, as were the press cars. This was no accident but the fact that Ford knew the 3-door was the sportier-looking edition.
The Mk1 and Mk2 Focus RS were both hot-hatches, not sports cars, but were only built as 3-doors.
For motorsport, where available, the 3-door versions of Ford hatchbacks were used.
Back in the day, all the hot-hatches that were desired were 3-doors, and anyone who bought a 5-door and modified it were ridiculed as it would never look as good.
