Run on BFG drag radials with a 60' time of 1.9, which is bad (the track wasn't prepped well tonite). With a 1.7 60' time (which I got before, the car would run about 11.4-11.5.

The M6 doesn't trap anywhere near 125mph, not sure where you got that number from. I have read a 1/4mile of 12.3@118 and a 0-60 of 4.4sec, in automobile magazine I think.

I personally don't like BMWs, but I think the M6 is a cool car, the M5 is a bit too ugly for my tastes.

Erik

No No agree, and I did not mean that at all.

I just looked at the time you used to get to 123 mph and compared it to what the M6 use to get to 125 mph. I totaly ignored the 1/4 time.

My "time to speed" numbers I have gotten from Sport Auto, I`ll see if I can find a link.

Cool, love to see it. Are the EU and US cars spec'ed the same or are there any differences? I know that alot of the EU cars are faster due to emmissions, safety regulations, etc...

Erik

I have no clue on AMG cars, but on M5 cars it is differences.
I spoke to the project manager for development of the M5 engine and he told me last winter that they was finnised with the Euro M5 engine and the US version was in testing..... So there are differences but probably not huge and mostly due to different rules regarding emmisions and such.


The M5 is starting to get launced in the US so as soon as the cars has covered some miles we will see.

While trap speed is good (about 120), ET is in the mid 12's.

Autocar tested it at 12.8 @ 119 mph:
Autocar's test results, reported by fastsaloons.com:

An Italian mag got 12.51 @ 191.9 km/h = 119.9 mph:
Italian mag's test results:

And lastly, Motor Magazine in Australia tested it this month. Result: 12.54 @ 192.5 km/h = 120.3 mph.
Motor Magazine's test results:

I'm anxiously awaiting test results from the US mags.

reggid

don't forget the other australian magazine "wheels" which got 12.5s @188km/h (116.8mph).

i don't think there will be much below 12.5 becasue of the SMG which has limited LC capabilties. I wonder what the time without LC will be that should be the more important number. A 6sp man (if it ever becomes available)should ultimately bring a slightly lower ET but lower traps too IMO.

Erik

It seem like they all agree on a trap speed of app 120 mph.

The Italian test is extremly slow in the short sprint. 5.68 sec 0-100 kph is way to slow, actually much slower than the previous M5... So either a typo or the traction on the test track was extremly bad.....

But do not forgett that this is from the M5 not the M6, for some reasson it looks like the M6 is considerably faster. Take a look at the posted race on our forum M5 vs M6.


EDIT: Forgett my coment of slow 0-100 kph.... I did not read proberly..... That time was for the 0-100 meter run...

Correct 0-100 kph was 4.54 sec. That sounds about right in line with most other mags.

But tell me one thing. When US mags or US driver are testing their cars at the 1/4 track, the cloc start to run as soon as you break the beam, right ?

In Euro test the clock start as soon as the car start moving, could that explain some of the differences between US times and Euro times....

1 tenths in the start ( 60 foot) equalls according you guys app 0,3 at the 1/4 mark, or have I missunderstood ?
I know I am on thinn ice.......

Improviz

Yes, they are all three aligned. So it would seem that, unless the US mags manage to pick up around 0.2-0.3 in the 1/4, that although its trap speed is about 4 mph higher, the M5 will not be a match for the E55 in the 1/4 mile, although *after* the 1/4 mile the M will pull due to its huge gearing advantage.

You mean rollout? (Click here) The mags use instruments mounted in the car, not beams as one would see at a 1/4 mile track, so technically there is no rollout issue.

Usually 1/10 in 60' comes out to more like 2/10 in the 1/4, but I'm not sure how the Europeans measure...do they take them to a 1/4 mile track, or are they using instruments as the US mags are?? I thought they used instruments...

Erik

No, as far as I know they use instruments, they do not go to the 1/4 track. Normaly they use either a stretch of road , airfield or a regular racetrack, like the straight on Hockenheim racetrack.

Did anyone see the video of the M5 vs M6?

http://video.google.com/videoplay?do...772668&q=m5+m6

Improviz

Sure did, and it's weird...given that both cars are within 100 pounds of each other, are geared the same, and have the same rated horsepower, the only explanation is that either the M6 has notably superior aerodynamics, the M5 wasn't as strong in this instance, or BMW is dramatically underrating the M6's horsepower.

In the Euro tests I saw for the M6, the car was shod with super-sticky near-track tires, which was noted in the reviews...this would explain its faster times to an extent, but it still doesn't account for this.

Erik

You are not the only one supprised about the result M5 vs M6. I was too.

One thing that could explain this is the fact that this M6 had more than 30 000 km of hard driving, while the M5 was relativly fresh with a LOT less km.
So the M6 was up to max performance while the M5 still need more km to loosen up.


The tires on the M6 used in 1 test is the Pirelli Corsa, a street legal road tires prepared for those who wants to track their cars from time to time. It is no race tire, but has soft coumpond and more posetiv surface ( less pattern ??) than normal tires. Useless on cold surface and hates water.

BTW: Has this been posted before.

Not a real test, just a presentation of 2 great cars..


While I am looking for videos, here is some from one of the best MB tuners. Enjoy....
