Ich Schreib das mal auf englisch: In Germany We call it BITURBO and in US they call it TWIN TURBO! There are always 2 Turbos on the Engine! So everybody is right! But it´s fact that the RS4 Ur seeing in the vid is truely a 4.2 V8 powered AWD! It has no Turbos at all! The 420hp results from the Maximum 8750rpm, and it pushes 420nm of torque! Besides the owner of that car is a good friend of me! So I hope U all got some answers! To the one that says it´s all about BMW: I´m sorry but I spanked a lot of BMWs with my little Seat Ibiza Cupra tdi (160hp tuned about 185hp)! Greetz 2 Xenondriver! See U in Stuggitown

You all wrong, its all about BMWs

hahaha, rs4 devoures m3s for breakfast. M3 is OOOVERRATED!!!! high strung no low end grunt, it sucks. and for the record, top gear tested a regular s4 (340hp) vs an m3 on the track and Quattro laid the woop ass. now imagine a 420hp rs4...:P

ummm look up the specs...they should be within one tenth of a second apart by 60mph and tied at the 1/4...even just if the M3 was totally stock and both drivers were pros. if it was modded, the M3 should have won easily. pshh a slightly modded 335i should be able to pull on that RS4.....just wait til the E92 M3 comes out this fall....audi fans...get you're glory now while u still can hahaha...just messin...nice car

aber echt hey, die labern und labern und haben keinen Plan!!! Wie das nervt! Sagen zum neuen RS4 twin-turbo... =/

manach haben halt keine ahnung hilft auch erklären nix :D

I hope you mean the old one, which IS NOT IN THE VIDEO! In the Video is a V8 RS4. The old one is a BITURBO. Just search in the Internet. Google and so one...

This is for 808537:

Please tell me you're joking about the biturbo. It was a twin turbo V6.

Twin Turbo? *ROFL* Thats the new model, it is a V8 and is not charged. And the old one has a V6 but also no twin turbo, it has got a Biturbo

yea the audi is AWD twin turbo'd its fast its UBER FAST spanked the M3
