I did read somewhere once (might have been Airliner World or Aircraft Illustrated, something like that), a 777 is capable of accelerating to 60 from a standing start in around 6 seconds. I have absolutely no idea if that is true, but I can only see it being a theoretical figure at min weight, max t/o thrust.
Rather impressive if true. Imagine the fun you would have racing away from the lights in that!
