    What's fast in a straight line a b7 rs4 or e46 m3,I know the rs4 would be faster from a standing start due to Quattro but how about rolling at 30 or 60 ?

    The RS4 has an extra ~80bph, it'll be faster everywhere. You'd need to get an E90/1/2 with the V8 to give a B7 a run for it's money. Around a track a CSL might do it, since the heavy nose of the RS4 can cause handling to be a little clumsy, but in a straight line it's the Audi every time.

    i have read that a lot of rs4s don't make quoted power due to carbon build up

    Don't believe everything you read - in 99% of cases when the lack of power was properly investigated the cause was found to be a problem with the vacuum pipes (which control flaps in the intake).

    Carbon buildup causing a large power loss is yet another urban myth.

    As an owner of both E46 M3 and B6 S4 I can confirm these are pretty close. On dry day the E46 is quicker across country and prob on a track, in the wet the E46 quick across country was scary soemtimes, the S4 is better.

    I can only assume the RS4 is quicker than the E46 but I havn't back to backed like above, the ones I have driven fee lquicker than my old M3. The E90 is very quick and again in the dry would out run the RS.

    I have found owning both marks with the same power, all year round the Quattro is better, if you want a bigger grin then the E46 is the one but only during the summer (one way ticket to oblivion in ice and snow!!!!)

    My AMG Merc was really quick but again in the winter was a nightmare. i used to work for Merc and had a 3.0CDI C class AMG spec then had a C63 6.2 ltr V8 AMG and that was the absolute ******** but any hint of ice and snow then you couldn't drive either, they were that bad. I spent an hour getting out of the Mercedes factory car park after being sent home early due to poor weather conditions, and it was flat tarmac with snow on it.

    My switch back to Audi now is so I can have 4WD and the power, it feels so much safer in the winter. The issue I have for the future is that I hate auto boxes, where does that leave me??????????

    i recently had an out an out race with my cousins SMG E46 M3 in my B7 RS4 and beat him in every situation (straight lines rolling from 50, from a standing start, accross roundabouts, etc) was just toying with him. i would say its fairly close without the S button pressed on the RS4, but the RS4 was always ahead. Completely different ball game with S button pressed!!!! View attachment 22075

    Interesting... pressing the S button makes no difference to the power output, just changes the mapping of the throttle pedal and the exhaust valves.

    Theres no comparison m8, in fact this comparison is an insult to the RS4 :)

    As a previous E46 SMG M3 owner im familiar with it's capabilities, i currently own a B8 S4 S Tronic Quattro
    & i was toying with the newer E90/92 M3 which is more powerful then the E46, i wasn't in sport & wasnt
    pedal to the floor etc...the difference of the 2 was more than apparent, he was really trying too lol

    As for handling the E46 steering is way to light for me as the Audi seems to be more advanced in respect
    of the steering feeling light when slow but at higher speeds the steering tightens up & the difference between
    the control & handling is so much more superior than the BMW's they are shocking in the wet too, again the
    quattro system both in the dry or wet is so good you can race these about & find it hard to lose control unless
    your a really bad driver imo, i've hit 150 in the S4 & its felt like im cruising at 80-100, do more than 80-100 in
    an M3 & you have to focus more as the handling/steering etc is **** in comparison.

    ...based on this the RS4 should be like a cat with a mouse with either the E46 or the E90/92 on the straight
    or the corners :)

    Every car i've owned has been a BMW or Audi, i've had an E46, E46M, E90M, B7 Quattro, B8 S4 Quattro &
    the Audi's are superior in handling, control, speed, technology & holding their price too :)
