It’s happened before though, those of us old enough to remember going from Group B to Group A will recall that was a lot worse initially than this is going to be. Can you imagine what Salonen felt like going from the 205 T16 to the Mazda 323. It must have felt broken.
The 1987 RAC rally was a bit sad, but already by 1988 the competition was good and the cars were getting quick. 2027 might be a bit crap, but I’ll bet by 2028 things will be on the up.
