how can the e92 m3 be this much quicker??

[P_G]

http://www.youtube.com/watch?v=u9VQUUjokbM m5 less power more weight
http://www.youtube.com/watch?v=mLToziJ96eI m3 csl (much less power/slightly less weight)
http://www.youtube.com/watch?v=mLGrJjJp ... re=channel e46 m3??!!
http://www.youtube.com/watch?v=nBZN29-nZZE z4m?!!!
http://www.youtube.com/watch?v=ABPPDYkB9Z8 ml63? these weigh about 4 tonnes!!!

seriously, if for everyone of these videos you have an excuse then like you said, there really is no point in me even bothering to try to gauge a civil response. ON PAPER the rs4 should be quicker than all these. Why is this not the case?

You are laughable with your 'point of discussion'

E39 M5 394 bhp but 368 ft/lbs of torque, 55 more than an RS4 and a larger N/A engine less prone to heat unlike compact V8 as pointed out in the test video
M3 CSL is 300+kgs lighter than an RS4 and not that much less on power.
A chipped E46M3 vs RS4. So what?
RS4 is quicker than the Z4M
And an ML63 has near 100bhp more and 130 ft lbs (41%) more which in a rolling test will always count.

Ok, i might as well give it one last try. Whilst the american dude runs off to find a couple more select figures for the rs4 that are few and far between, let me put it to you this way.

My 'point of discussion' is that it doesnt matter if the american dude finds a magazine quoting 2.5 seconds 0-60 for an rs4, I dont care if an m3 is quicker than a rocketship, but why cant an rs4 with the same or better power to weight ratio beat any of the other cars ive mentioned. I've read on here that they are down on power. Is that a reason? Are they clogging up with carbon on top of this. If so most rs4's now must be what 350hp. Is that why they keep losing in the videos. What about this one- 220bhp per tonne and the aerodynamics of a brick and yet it is still reeling in a 414hp car with a better power to weight ratio

Instead of banging on about rs4 magazine figures which if nothing else further confuses my point (if you say it does xyz why is it not doing this in the videos) can somebody please explain why rs4's do not deliver in a straight line. what wheel horsepower do they putdown in your experience, are they slowing down as the engines get older? do they have a poor drag coefficient? etc etc what is it? i dont care if you think an rs4 is 10 times better than an m3- heck i will even agree with you if it means somebody would just answer my simple question...please

We already have yet you continue to ignore what is baltatntly been put in front of you. The fact you have 'read' RS4's are down on power shows you do not do your research properly. Believe what you want, all I see is you banging the same drum and trying to use Youtube clips to justify your original post.

And I doubt you are ever going to be in a situation when any of those cars are going to have the legs on you when you consider the speeds at which those cars start to really pull away on the videos you appear to hold as gospel. Andd if you do, then eat some humble pie.

Do you even have an RS4? Or are you thinking of / buying? if not, why are you even asking on an RS dedicated forum?

Real world experience on the road (as opposed to M5Board) suggests the cars are nigh on identical in performance...

Game, Set, Match either owner.

i couldnt be arsed to read all 5 pages of this thread....my 2p is that i have had a drag with an M3 and it was even stevens....i think others have had too.

And if a. Magazine says M3 is faster, then there is B. Magazine that says the opposite

So what

When it snowed how much faster was the M3 then?!

[Sims]

..

the only real test: Ring 7:58 vs 8:05 faster with a 28% wt/HP disadvantage
1/4 mile 12.8 vs 13, same test, same magazine...faster, yet 14% LESS delivered HP and 12+% MORE weight...

hard to believe, but when you consider the engine was designed by the same guy who did the M3, and possibly the best engine BMW ever made, the e30 M3 (S30), it is understandable

...

Not that it helps the debate much, but the comparable 'Ring times are 8:05 & 8:09, so let's stop banging on about 7:58 time.

The E30 M3 engine is my favourite BMW engine, and for the sake of accuracy it is called the S14. The last version of that in 1990 produced 238ps from its 2467cc . That would be the equivalent (if there is such a thing!!) of 402ps for a 4163cc engine. For the E90/92 M3, they achieved 420ps from it's 4 litres.

Are we also banging the same drum, but to our own tune?
I consider Youtube clips irrelevant, but let's not be in denial that there are differences in the power outputs of RS4's. Last week-end, one RS4 made 371 at the MRC dyno, whilst the owner of another that made 400 suggested it should have done better.

As many have said, these are in the same window. Let's be positive to newbies.

Horses for courses.

Audi' are popular in Swtizerland, whilst the RWD is the preferred weapon choice on race circuits.

the 400 car has been remapped, de catted and had its valves cleaned at some point vs. a 73k car thats never been cleaned.

apples and oranges

also, the torque figures were very similar

Do we know the specs of any of the Youtube cars?

Normal RS4's typically make 370 on a RR.

That is why I suggested that the 'Ring cars and the time of 8:09 & 8:05 was proof indeed that they are about the same.

We are not disagreeing, but merely acknowledging that there are so many variables, and yet we arrive at nearly the same result on the road. We should celebrate that.

David, did you and Billy ever get the chance to 'compare' your cars out on the open road? Would have been interesting to see any differences.

[HYFR]

no, Billy was there on the sunday...

Ah, ok.

You know, all of this has got me thinking. For the next big forum event, why not have a 'twin-shootout' day?

So basically, you take the 'dyno day' a step further - you run each car on the dyno to see what she is putting out. Then, immediately after you run those cars against one another (on a private test-track) to see how they compare. Would be pretty fascinating and loads of fun as well!

Fraught with risks, but a good suggestion.

Take it a stage further, and have a few V8 M3's there as well.

But seriously, let's not be under any illusions - a standard B7 RS4 will nearly always have a shortfall on the Dyno. 370 is a good number for a well maintained RS4, and a good match for a V8 M3 on the road.

At 371, your car is better than most RS4's
