Please explain? These specs exist on many an RS6. I said it in another post, 10 years of development and a slightly quicker car in the S7 and RS7 models isn't attributed to the engine IMO. I attribute it to the transmission. The few 10's of a second are associated with more gears which can afford increases in gearing to aid in acceleration which the 5spd in the RS6 can't match. Add to that improved internals that make quicker shifts and voila you get a better end product. I would hope that a full decade of development along with lots of $$$$ would put a smile on ones face.
