That would be quite the weird behavior. Jack wrote some time ago, as the new suppliers were entered, that the reason behind that cap in Elite is that how the game is programmed means it can't work with numbers higher than 100 for the car attributes. I didn't try it though, so I can't tell from own experience.

if elite is capped, why dont you get an achievement badge for reaching maximum development in any design area?
this season and last season I reached that cap of 100 in more than one design area and didnt get my badge in achievements.
Some of the achievement badges are somewhat broken and the Innovator one is one of the more notorious troublemakers. Just checked and it didn't show up with my account here as well.
