So who actually tracks their M5?

BIMMERPOST
     Featured on BIMMERPOST.com
And when I say track I mean multiple DE track days per year.

See I'm considering a new M5 over my current M3. With the addition of AWD I think it will make it a much better all around street car / kid carrier / winter driver.

But I'm not sure how it will do as a dual track car. Sure it can go on the track fast but at what inconvenience ?
It is basically like a 4 door Nissan GTR. (Fingers crossed). Or will it just be a heavy lunk ripping up its tires in 2 hours and causing me to pit every 30 mins for gas.

But this further raises the question about who actually tracks them? I've never seen an M5 on the track. So who here is buying a new one and plans to actually routinely track it?

Come to Cali, you will see M5's on the track. I have taken both an E39 and F10 M5 on many track days. That's why I love the M5, it can be a well-tailored business suit during the week, then a monster on weekend canyon runs and track days.

All generations of M5's have been track worthy. However beginning with the F10, owners have preferred not to track it because of its very heavy weight, and unforgiving nature if a mistake is made because of this weight, but it is definitely suited for track use. After all, all M5's are designed for the track as well as the street. The heavy weight of the F10 and F90 mean that you will need to upgrade the brake pads if not running CCB's and you should upgrade brake fluid. The F90 has the advantage of AWD but is more unbalanced than an F10 with the F90 having a 55/45 distribution. However because of the AWD, the F90 will be able to perform miracles on any track, whether a tight technical one or one with long straights and fast corner entry speeds. But you will still be running through brake pads and tires at an abnormal rate due to the sheer weight of the F90, but a competent driver should have no problems destroying an M4 on the same track.

So to answer your question, yes I've tracked the M5 many times. Between my E60 and my F10 I've had a lot of fun on the race track. The F90 will be great fun too, just be prepared to spend a lot of brakes and tires, which a lot of people have to pay for anyway due to the nature of a racetrack.

The F90 Competition Package will also be a nice upgrade for those intending on tracking the F90. I've always found the body roll on stock M5's or M5's without the Comp Pack to be excessive.

THIS!

I would imagine the CF roof will be a significant improvement over it's predecessor. For me, I may take it on the track for a few laps just to see how she does. But nonetheless she's still heavy and it will feel cumbersome. If you want to buy a car for occasional track use, a M5 is not ideal.

On the other hand, the track is one of the few safe legal places in the US to explore what the M5 is capable of.

This was me in the F10 M5 last fall at Virginia International Raceway. The M2 I'm chasing is a fast car with a good driver. Even though I fell behind, it was a great session to stretch the cars legs..

The correct figures for weight distribution in typical spec with fluids and driver are:

F10 M5: 52.5/47.5
F90 M5: 51.9/48.1

I've seen 54.7/45.3 posted for the F90. Are there regional differences or was that a car without fuel?

This easily mis-interpreted data piece? The figure noted in it represents the percentage of unladen vehicle weight in relation to the Gross Rear Axle Limit with 90kg trailer receiver load factored in at Maximum Vehicle Weight. It's skewed further by that last figure remaining the same as UN/ECE variants but the maximum payload reduced by 165kg (Not Certified for Towing in the US and without nominal luggage compartment load: -90kg/-75kg respectively).

I don't know about anyone else, but I tend not to drive around with 200lbs of stuff in my trunk.

The F90 carries more weight on its front axle than the F10, full stop. That's why BMW changed the tire stagger. The 54.7%/45.3% distribution is BMW's USA published number, based on curb weight, which includes all fluids in place including petrol (usually 1/2 to full tank). Adding a driver is not likely to change this much as the driver's H-point is about 1/2 way between the axles.

There's more to handling and driving characteristics then weight distribution. Vehicle dynamics are just that - dynamic. I wouldn't worry about a static front weight bias.

Sorry, can you clarify what is the configuration of the car when measured with a 45.3% rear axle weight distribution? Is it fully laden, or is it an empty car with no fluids, or (I am guessing) somewhere in between?

It's without driver, passengers or cargo, 90% fuel, and all other fluids full. The caveat is recognizing 45.3% represents the static portion of the vehicle mass when subtracted from the Maximum Permissible Rear Axle Weight in order to define the payload distribution limits for tires, suspension, steering, etc. For Curb Weight Distribution under the same conditions, it's 2.3% bias to the rear (52.4/47.6). Adding 68kg for the driver and topping off the fuel tank moves this aft an additional 0.5%.
