Just wish to share my thoughts after drving my S3 for two months, and see if other S3 owners are in the same boat. Is it just me, or does driving an S3 feel lika a different car every day? I have had the car now for a bit, and i'm sure that some days it feels fast, very fast, and others, it feels like a dog. The only explanation I can come up with is the ambient air temperature - and i know this can hurt a turbo'd cars performance, but really by this much? The difference i'm talking about is the difference between making a slightly shadey overtaking manoeuvre, and playing it safe - you dont have the confidence that the top-end power will come through. Does anybody else have these problems? Do you just accept that when its 20+ degrees outside, you car just feels loads slower? I would never have imagined that such a difference could be felt so much.
