Wondering why it does that?? and on a scale from " red lining the rpms" to " putting an A8 in neutral while rolling to rev the engine at a prius," how bad is that for the car? 
In all seriousness though should I not be worried about it as long as the engine isn't revved during cold starts? |
Are talking about revving it right away while it is still at high idle during a cold start? If so, it sounds like you are at high idle during a cold start. You should really wait a minute or so for the idle to come down a bit before taking off. It is a best practice to bring the engine up to normal operating temp before you get all rev happy. Check the oil temp to get an idea of how warmed up the engine is.
And yes is not a good idea to put your A8 transmission in netrual and rev at a Prius or any other car for that matter. Odds are that the other person will think you are an immature jackass. Just because the car is fast and makes cool sounds doesn't mean you have to get all weird about it. If you have a passion for that kind of driving you should head to the dragstrip.
