MDM allows a decent level of sliding.. if you're to too hamfistd about it.

from my experience, provided you re-act to the slide, through steering corrections etc, you can barely notice it cutting in if it does at al.

If you just boot it, and don't do anything it will cut in harshly.

It's funny, all this Dsc stuff etc. I leave mine on as I just cba to turn it off. I used to drive a 300 and 400 plus cossie with no traction control, how did we ever manage not to wrap around trees? Lol

I agree, I never needed traction control in my Cerbera 4.5 or my 200sx...I have always wondered why recent M cars have traction control on them in the first place surely your right foot and a Slippy Diff does a good enough job anyway without the need for the nanny state help.

I couldn't agree more. However, I also look at all of the rolled or seriously damaged M cars on the Quarry Motors site and wonder how ham-fisted people must have been with them to crash them in such a way.

For example:

Fist's of Ham and Feet of Anvil's, as M's are well balanced, as are most BMW's tbh. My car not only tells me what its doing, it sends me a letter about what its going to do a week before it does it.

I couldn't agree more. All my Ms and every other M I've driven have generally had lovely, exploitable, beautifully judged chassis.

To even suggest an M car without TC is ludicrous, there's enough of them being put through trees/walls/fields/any other immobile object with TC, for starters insurance would go through the roof, and let's not forget, it's a car built for the masses not self professed driving gods

I liked the MDM in my E90 M3, it offered a perfect amount of slip and the reassurance that unless you were being completely hamfisted it wouldn't go pear shaped

One example I had of it saving my bacon was when I went to overtake a car doing 35-40 mph in a 60, small queue behind it, so it was a multiple overtake, straight piece of road, wet, dropped a few gears, went for the overtake and the car went completely sideways when the NSR wheel lost traction on a white line, midway past a car, had the TC been off completely I have no doubt there would have been an accident, as it was I reacted quickly, TC did it's job and a brown trouser moment avoided

"Its a car built for the masses" that pretty much sums up why the E9x M3 never lit my fire, I am a million miles away from a driving god but if I am driving a powerful rear driver I use my common sense and right foot to keep me out of trouble in the first place and even then I almost wrapped my Cerbera around a tree in the wet as that was a handful when it was slippy!

In fairness if you want to enjoy the M3 without the safety net you can switch it all off which is a bonus but I think half the time you have so many who rely on the electronic aids that you wonder if they actually know how a RWD car actually feels like when it is out of shape because with the aids on they don't behave like a RWD car should anyway.

To emphasise what cpufreak said, I find that when the M3 is driven properly in MDM mode, you hardly notice it's there. It seems to allow progressive slides at quite high slip angles. It also allows a fair amount of wheelspin again if it's progressive. It's aggressive slides/spin that trigger it more readily. It's a pretty good safety net for the road.

I do agree the M`s are very well balanced and my E92 M3 had the best chassis I have experienced it was communicative, I remember a friend of mine years ago smashing his E36 320i up on a straight dry road with only 150bhp and I thought it can only be a complete disregard for the car or a serious lack of experience.

I found MDM mode amazing on a track. It lets just the right amount of slip to balance the car exiting the corners before cutting in.

None of the rear wheel drive cars I've owned have ever been designed for drivings gods, yet I never managed to crash any of them. My first car was a 2.0 125bhp Sierra Sapphire, never crashed that. While you say its ludicrous to suggest an M car without TC, I say its more to do with that people are too reliant on driver aids, so when something happens like a car stepping out, people do not know what to do. Most people who jump into M cars have probably come from FWD shopping trolleys and the like, an M car may be their first RWD car. It says more about the people who drive them, and than the car itself, a point you proved below I'm afraid.

Probably a mixture of both.

BMW did some market research a few years back and 80% of 1 series owners didn't know that it was a RWD car. The fact is, outside of enthusiast sites, most "normal" people wouldn't have a clue. I've no doubt that my wife doesn't know that her 320D is RWD.

MDM on my CSL and E60 M5 made a big difference. It allowed the rear to move an appropriate amount for road driving and allowed for a deceng getaway form a standing start where DSC would cut the power.
I've found the same with the f10. It loosens things up nicely. I swear the car sounds louder too.

Ta. I haven't purchased a car for two and a half years so that must mean I'm pretty happy smile I used to swap every six months or so.

DSC off and Cup+ can equal this:



With the throttle to sport+ once you get over 6k rpm the car can bite.

Yep, but in my defence I was 200 miles away at the time of the accident, my mate thought the DSC was too intrusive and well, that was the result!
