Group b was a time of revolution, not of evolution. Nobody cared about perfecting the existing technology if by the next year it was already obsolete. Instead of perfecting handling and winning a little time, they just put a bigger turbo on it and won a lot of time.
Sure, everything else also improved, but the revolutions made the cars suddenly so much faster that evolution could't keep up.
So what you had where always new, very fast, but very imperfect cars.
Nowadays there are no more revolutions possible, so teams put their effort in small changes. They perfect the cars, trying to make driving as easy as possible.
