What's the fastest idling car? No, I'm not talking about a car with high idling rpms. That's all that ever seems to come up when I search this question. I mean what is, in terms of straight line speed, the fastest automatic transmission car you can get in, start, put in Drive, let off the brake, and let go without touching the throttle (500-800rpm)?

I ask because I have an automatic Mk7 Golf R, and it idles pretty fast and pulls pretty hard when I let off the brake. It typically idles around 5-6mph, and I've even had it get up to almost 10 without touching the throttle! The idle is so powerful, it idles uphill in Drive AND Reverse!

This seems like a very fast stock idle compared to most other cars I've driven. Are there any other stock production cars that can go quite fast at idle?
