Let's do some elementary calculations, and make a few favorable assumptions.

Curb weight RS6 4060 lbs, with 4 big guys, 4860 lbs. Curb weight of my car (1/4 tank, lightweight wheels and tires), 3700lbs + me = 3860 lbs.

Now take drivetrain losses in an automatic of 20%, manual 15%. This gives Audi RS6 360 whp, BMW 545 276 whp. Calculate the lbs per hp for both cars.

Audi RS6 - 4860 / 360 = 13.5 lbs hp

BMW 545 - 3860 lbs / 275 = 14.0 lbs / hp

Close enough isn't it? Especially if he didn't get a kickdown from the slushbox.

You ought to get that cough checked out.

 

no, they were only sold as automatics in the US. unfortunatelly. and MTMs software broke a few of the auto trannies.

they sure do, from a standstill,
but when in motion already ... unless you are running in the low 1K RPMS, or out top of the spool range, you will move - QUICK!
if you have ever driven one, you'd understand. but the new RS4 will most likely beat it with its V8 FSI 4.2l & 420HP, as well as its new all wheel drive system that is 60R/40F


the DT loss on the quattor system is actually more like 30-35%, so it'd be even closer than you estimated.


damn cough .... I should go & see a doctor about it. ;-)

 

Doesn't weight play less of an issue when you're already at speed.

Because a RS6 can pull away from an e39 M5 let alone a 545i

 

Maybe it was just a S6, and not a RS6? ie no turbo.

 

The boys on the Bimmerfest board say otherwise.

'yup, the e39 m5 is faster than the rs6 from 0-130, and in highway rolls. the audi will have it off the line, but the bimmer will slowly pass it above 100.
'

 

Definitely an RS6 - I've driven one. A friend of mine got the first one in Cincinnati, and at first, I thought it was him.

Also, weight is less of a factor at speed. I don't know what the RS6 drag is compared to the 545. Also, he was in front, so I may have benefitted slightly from a draft.

 

For some reason, I just happen to have the May '03 issue of car and driver handy....

0-60 / 0-100 / 0-150 / 1/4 mile

RS6: 4.4 / 10.7 / 30.9 / 12.8 @ 108
M5: 4.9 / 11.5 / 29.2 / 13.4 @ 108

So yeah, I guess the M5 would take the RS6 over 100

 

well.... I don't think your wheels cut 100+ pounds off your car... the weight of the 545i listed at 3,814 pounds....

either way, he did have a lot more weight in the car..... you can roughly estimate 1 car legnth per person.....

I think the real issue that isn't being mentioned is that the RS6 is AWD, and while that is great for getting a jump off the line, it really kills the car when at speed... the AWD causes much larger drivetrain losses.... you'll always see better 1/4 mile times, and lower trap speeds with AWD cars....

Wolverine,

Sorry about that F1 experience. I watched the whole thing on TV and it was awful. I can't believe it ended like this. A really bad move for F1 in the US.
On the positive side. I am a huge fan of Schumi, and that way he got 10 points in the championship that otherwise he probably would not have gotten.
