Unmodded RS4:
270 km/h (limited to 6300 rpm in 6th)
Without speed restriction, no other mods:
282 km/h (see
http://www.mtm-online.de/html/detail.ph ... &FZID=RS4Q)
The limiter in stock is very soft, it is like you've run into huge wind, just won't rev more.
As for real modded RS4's, 290+ km/h depending on the level of mod's. One fast wagon
