Not much of a difference in acceleration....

the R8 R-tronic system is other that S-tronic in other Audi models

The R-Tronic is different from the S-Tronic ( aka DSG). The R-tronic is a system based off of a single electronically controlled clutch. The S-Tronic is VWs new double clutch system which will automatically prepare the next gear in line for seamless smooth shifting. Shifting with the R-tronic will still yield some head snapping with forceful acceleration as the throttle is cut momentarily during shifting but with better performance with shifts in the 200 ms range. Hope that helps

Well, I hope it's much better than 200ms. I heard that the BMW 335i changes gears in 100ms(the auto trans of course). The DSG has a superb shift time of only 8 ms when the computer has the right guess for the next gear (usual). R-tronic is fast (I drove it on & off the track for a while) but it's hard to tell how fast in ms. I really hope your 200ms range is a guess, and a wrong one

i sure hope im wrong too! but I do remember reading 200ms somewhere. I can't remember where though, but i'll try to find out
