For those curios, we made 5-6 runs from a stand still, in every case I immediately jumped a car ahead but he took off while he was still in first gear to go 2-3 car lengths ahead but never gained more than that. In fact if we had more room I think I could have made up some ground. Not bad for a 4000lb+, 7 year old saloon.
We tried leaving it in automatic and also tried the paddles - same results.
As a comparison my 08' M3 would take him every time from a rolling start (5-10mph) and stay 2-3 cars ahead of him while stretching the lead until we ran out of room.
I plan to do some performance upgrades in December and we will try again to see what happens. Perhaps I can get it on video next time. Stay tuned...
