The lack of traction in the car has pretty much been its most frustrating trait. Other than that 30 months of ownership has been great. Wouldn't get another until AWD was available. Will still have another RWD Bmw but one with less power as its wasted most of the time. Went to overtake today with the kids in the car, traction light before I had crossed the white lines , then a tesla followed expecting me to go 3 figures but the conditions or cargo didn't allow. No doubt the Eco warrior was laughing !

I have seen traction considerably improve this week with the temps rising above 5 degrees... (Only got mine late last year)

But yes it can be very frustrating
But if you can reign in the throttle and short shift it should still accelerate as swiftly as any other RWD front engined car... In theory of course

It still amazes me how the traction light still lights at some absurd speeds if you simply plant your foot and gentle fettling of the pedal from the off and once going is always necessary yes

Apart from the seats in mine, this was the biggest bug bear with the car.

Seats are fine in mine, and the split rear seats was a great option being able to 'throw' a bike in !

To the point where I'm thinking of moving on to a different BMW in 6 months.

Have to say my M5 is an utterly brilliant, brilliant car however I also always drive it like I'm trying to headbutt the horizon.......however when I drive my Mrs's X3 2.0D M Sport I drive like a normal sensible individual!

I know what you mean - I drive everywhere at Mach 1 and then find myself thinking 'FFS' whenever I have to back off to what would otherwise be a reasonable speed. The car has the tendency to redefine one's perception of progress.

Is yours on the 20" option wheels.

Just watch those Teslas as the higher powered ones would eat an M5. That would be over-ruled when the Tesla needed a charge in 100 miles, but they're virtually unbeatable in a straight line.

Up to legal UK speeds I agree but watch all the videos and at higher speeds they are not as epic. I'd ignore one off the line but 80ish onwards in Germany and I'd expect to win!

No mine has 19 inch wheels, was thinking off the line they are very fast but when three figures come they would struggle.

Anyway it's not a thread about a tesla, just poor traction in the M5. AWD hot hatches can keep up with it in certain conditions so renders 560bhp useless 10 months of the year .

But that's generally the laws of physics not the cars fault.. But TBH 0-60 is irrelevant to me, cant remember the last time I tried to race anyone from standing start even in my stage 1 TTRS which would do it in 3s dead consistantly (asseemingly) I only used launch once out of curiosity.

As anything pros and cons... The Audi's can be quicker in many British conditions but there pretty dull doing it, at least with the RWD it keeps you concentrating a lot more and more inputs are required..

The 19's have slightly fatter sidewalls which could well improve grip by giving the tyre/wheel that little bit more twist tolerance (if that makes sense)

If you're having lots of traction issues I would get the geo checked over by a specialist. Not the same car but I had a tail happy Z4MC (wheelspin and twitchy tail at 70 mph in the wet). A trip to center gravity found minor rear spec issues and a steering wheel angle sensor out of alignment. The car is much more planted now and I can press on in most situations with complete confidence in the chassis. With the torque you have at your disposal rear geo needs to be right!

Are you in D mode (Automatic) and then hitting the throttle hard causing the car to kickdown ?

I find using manual mode in a slightly higher gear and feeding the the throttle in gives me more than enough overtaking capability.

/\ Tried that as well, better but it doesn't escape that fact that the car in the UK climate struggles to get it's advertised power down.

Still a good car, and I love BMW's. Its alway's been a trait of high power RWD but this much is wasted.

M5 XDrive for the next release?

I never use auto mode for that reason (amongst others) nasty lurching head-nodding kickdown always upsets any car, let alone a 600hp+ one.

Even if I am being lazy in D, I always use the paddles to select the gear before accelerating then apply the throttle.

Do you mean lack of traction or overzealous traction control?

I find you can make better / smoother progress in MDM mode, let the rear move little, it's quite safe and won't kill you at the first bend like the safety police will have you believe. A little wheel slip in a 2 ton car with that much power is inevitable but unfortunately the fully-on T/C won't allow any. It's so quick it will cut power before you have an inkling about any wheelslip, which in a way hides the true road conditions from you.

Those annoying throttle-cutting episodes pulling out of T junctions or mid overtake etc just stop happening in MDM and you can actually feel the engine doing what YOU ask of it.

Personally I pretty much always put MDM on and only leave it off on M ways etc.

Tyres make a massive difference. Mine is currently running on P-Zeros. They are shocking on the M5. I'll be swapping back to PSS very soon.

Very true, I posted a very similar thread a couple of months ago and it turned out my rear tyres were shot. Replacing them transformed the car.

I could certainly see that being the case North of 100.

That does surprise me then as i really don't struggle with grip. Have heard the 20's do suffer worse than the 19's & the MPSS which mine has fitted give far better grip than the P Zero's, but other than the expected wiggle & a couple of moments, mine's not suffered with Traction issues, even with the uplifted outputs. When the ambient temps are very cold &/or very wet the car will struggle as the MPSS only excel when up to temp & in the Winter that's impossible.
