Hi All and merry xmas.Ive been driving the clio over the past days and have found when you start hitting the higher revs the exhaust vapour increeses loads.Is this common.
Well there will obviously be more exhaust gases being pushed out at higher revs, so I'd say yes.
The exhaust vapour you refer to is condensation inside the exhaust being blown out as steam. My 172 Cup has been doing the same a lot recently with this very cold weather.
Perfectly normal. My old 182 used to always do it in weather like were experiencing at the minute. Sometimes you couldn't see through the back screen at all from the steam lol
