+1. My car gets babied (and I mean babied) if it's anywhere above 30. Even mid-high twenties I start taking it easier. I even try to limit my a/c use at times.
In the GTI, I notice moderate variations in performance between, say, 10-20 degrees, 20-25, 25-30, and so on. Each of those steps feels like a passenger's weight to me. 10 degrees and one up versus 25 and a passenger - feels like 15kw!
