My new VXR - picked it up on Saturday and just completed Reading Portsmouth and return yesterday and reading to Wakefield return by Nottingham today (so now covered 650 miles in total) seems to gas out a lot of water vapour when sitting at traffic lights. After a 400 miles plus run today it must be well warmed up and well cleared out? Never noticed this with my old M5, is this normal? I know it’s quite cold, and I am sure it’s only vapour, but just wondered if anyone else had noticed this? Cheers - oh yes, and its goooooood!!
It really is nothing to worry about.
As Ringram says you cannot have a car without it and is there all the time, just lower ambient temps etc make it more apparent.
A bloody great 6.0 ltr V8 will make more "steam" than a smaller engined car and it also depends on exhaust tip angles, wind directions and car shapes (at the back end) as to how apparent it becomes.
Saying all that my old Scoob used to make so much you could not see the cars behind when sitting at traffic lights

I'm sure I've read that every gallon of petrol produces a gallon of water.
That sounds about right as petrol is c5h7 or whatever, all the H becomes H2O, there is nothing else that combines with the H, basic oxidation reaction etc. With some NOx thrown in from the N content of the intake air.
