13.0 in the quarter mile.

410 dyno horsepower (flywheel)

8200 rpm rev limit.

Actual weight 1728 kg (3802 lbs) instead of claimed 1650 kg (3630 lbs).

Only time will tell.

And after you do it twice, you'll be limping to your service dept. for a new clutch. :-P

Here is what I just got from my internal contact at you know where...

In general, US Audis are 200 lbs (give or take a few lbs based on engine and transmission variant) heavier than in Europe. This is due to a lot of North American-specific safety equipment, and that our standard cars are simply better-equipped. We don't have roll-down windows in the rear doors, for example, like in Europe and the rest of the world. The specs (including weight) are available to all dealers on internal training guides.

I will get the official number from you know who and you know where...later today...and post here.

of what? everything is relative. a standing start tells you a lot more about a car's traction and ability to apply the power; a very good parameter to access both the drivetrain and the transmission, and the suspension, and the driver's abiltities.

I know that the M3 is good comparison for the RS4, but it is a different car.

Let's put it this way...the RS4 and Z06 may seem not too far off in 0-60 time...but at the end of a quarter mile, the Corvette will be over 15 car lengths ahead and pulling very hard away.

0-60 IMO is a better measure of sub 300 hp cars.

I just checked the b7 rs4 forum to see whats happening &amp; couldnt believe b5 is hatin....already. zo6 vs rs4 wtf?

But at least now we know the general reason why ours is heavier than Europe.

You could think from the 0-100 km/h times (3.9 for the Z06 and 4.4 for the RS4) that the cars aren't that far apart.

The quarter mile and trap speeds shows an entirely different story. (11.5@126 vs 13.0@109 or so).

Also from a roll, the Corvette will pull away from the RS4 at about the same rate that an RS4 pulls away from a stock A4 2.0.

thats alot worse than i expected. again, not to magazine race, but by comparision, stock sti's have done 12.9 1/4 (though only traps around 106) with 300hp and not alot less weight (sti's come in at around 3300lbs). i wonder whether it comes down to the ability of the rs4 to launch? i know a car like the sti can be launched quite well. obviously the rs4 isnt meant to be a 1/4 mile car, but i think 1/4 miles is a good gauge of performance

Your stock STi time is very fast. Most mag test I've seen are just over 13 seconds at 103 ish mph.

A stock STi will pull 1.7' without too much problem. The RS4 will cut a 1.8X at best IMO.

Where did you see a 12.9 on the STi?

do a search under certain posters' ID's and you'll see patterns. i won;t say any names ;)

on iwsti who have run 12.9. most guys run 13.1ish with a good launch. most mags dont launch the car, or if they do, they're not as comfortable with the car (and prob dont want to break it), and so they usally quote 13.3; these same mags claim 0-60 time - even if they are irrelevent - of 4.9 when a skilled driver can get 4.5!! let me find you a link ...

I am sure there are people on this forum who will be able to pilot the RS4 to quicker times than published.

As you stated, the methods used will go above and beyond what the magazines do...and are certainly questionable for the car.

some guys wont be able to get 13.5 out of an rs4!! its all up to the driver. not having driven an rs4, i dont know how it will be to launch or how durable the cluthch and drivetrain is, but i do abused my sti. the sti's clutch is amazing and drivetrain have proven to be ridiculously resilient; many guys will run stock cluthes up to the 400whp mark. while i was searching around, i came across a quote from a c&amp;d review where they ran 13.1. typically (and i cant find the link right now), but if you are running 1.7 60 footers in an sti, your looking at a 13.1-13.3 1/4. those who can get into 1.6 60 footers (this is possible with a bit of practice), are looking at 12.9-13.0. from past experience - and this is all i base my opinion of hte rs4 on - with a proper launch, the high revving nature of hte motor should net times in the high 12's, prob 12.8ish.

did the clutch slip afterwards?? what indicates the fact that you think the clutch is fragile, which you imply by suggesting that one should limit launching.

3957 lbs / 1795 kg.

and the S4, for that matter.

That are 78 kilos apart, that's 171.6 lbs difference. What gives?

I wish car magazines would be more precise or at least include more info when they test these cars. I know some mags give the temperature, barometric pressure and altitude the test were conducted at.
