Just a random question- When I'm doing some spirited back road driving, i do tend to get carried away sometimes. I never had this kind of confidence in my F30.

Has anyone ever managed to over steer or spin out in a RWD G20 around a corner ? Or is that not possible with the stability control engaged?

I barely go fast enough to even hear the tires squeal (this car has some high limits) but just curious. And if you do begin to oversteer/spin out- what's the best way to stabilize the car?

Turn the wheel in the opposite direction (in the direction of the skid). It may be possible to spin out in sport plus where traction is partially disabled or by pressing and holding the traction button until it turns off completely.

My M340i Xdrive would let the tail slide a bit in Sport Plus.

[TTG]

I have both on the track (BMW Ultimate Drive Event) and out in wet pavement. This car is quite tail happy if you get on it for sure.

Yes, almost spun out and wiped out a few cones in the M340i during the UDE on my first practice run. DSC was on and I recovered quite easily. Came in 2nd in my session despite my misstep. You can easily manipulate the rear. I did find that the limits weren't as high as my F80 M3 CS, but still very impressed given the car's added size. Best non-M 3 series I've ever driven. I'd love to turn off all traction control to see what it can really do, but they wouldn't let us

Yeah they also let you take it on a test drive by yourself but you agree not to turn it off. Not sure if they software restrict it on the car though. Did they also let you track the x drive?

well today i discovered something

in almost comfort mode (Sport individual - sport plus engine, comfort everything else) in the wet (10C) i managed to spin the car 90 degrees with no stability control intervention, i tried to find the limits of TC, when you gently steer and floor the throttle nothing will happen.

but if you floor the throttle fling the steering wheel the rear end flew off and applied the brakes and the car came to a stop around 90 degrees.

this "allowance" for GTA mode appears to be the same in "comfort", sport and sport individual.

the difference is in sport individual if it senses you want to have fun it will allow you to do a gentle drift. this mode feels safer than the "comfort" mode.

i also tested DTC and the car was wild as heck, flew around everywhere.

i don't want to blame the P Zero runflats as i'm not a tire tester

[eluded]

Yes

Traction Control unfortunately doesn't allow you to violate the rules of physics. It's even in the manual.

Know the cars limits and yours.

I did with my xDrive when it was wet out with my DSC off in sport plus. I took a corner, gunned it, and spun 180 deg out. I did not expect that. For perspective, I'm running PS4S tires.

[Mason Hatcher]

At the Performance Center School last year we had lessons on under and oversteer correction. 300' polished concrete circle that is wet. Traction control off, 2nd gear, about 30 mph and punch it. You would spin out. We did the drill until we learned to control it.

With the nannies on the car just wouldn't spin.

[EXE46]

Drive it hard enough it sure will especially if the tires aren't MPS4's. My RWD does this but that's part of its charm. I don't need an XI to dumb down the drive. Worst of all are the RF's, those struggle for traction even on dry pavement if you drive the car hard enough.

[iifymbro]

any kind of wet pavement + fully disabled traction control = drift mode

Just a little blip of throttle in a corner and the rear will step out (RWD, I'd imagine the AWD version takes a bit more)

[G30M]

did more tests, couldn't help it. wet weekend, woke up early on Sunday ...https://g20.bimmerpost.com/forums/sh...72&postcount=1

[G30M]

from the post

First DTC mode (MDM/short press TC OFF)

Car flies everywhere (oversteer), wild as heck, computer responds to steering countersteer input to get the car rotated to where you point it. Yaw allowance is pretty generous, car was 45 degrees sideways by the time i countersteered and then it was flung the other way, in fact almost 45 degrees the other way, another countersteer brought it back on track. Drifting is possible in this mode.

If you do not counter steer the car will just spin at the mercy of physics. Applying brakes did not seem to halt the spin.

Next Sport Plus, Sport, Sport Individual (everything in comfort setting!). All seem to produce the same stability computer reactions.

Interestingly, once friction runs out on the rear (violent steering input & acceleration required, 255 rears!) it is allowed to oversteer/spin. If you do not counter steer the car will just spin at the mercy of physics. Applying brakes did not seem to halt the spin.

However it is very easy to catch the oversteer with countersteer input by amateur (never had the opportunity to track a car). This suggests the power is cut a little bit compared to DTC mode, where little to no power cut is applied, drifting is possible. In all sport modes, very controlled sliding around a bend is possible.

Comfort setting - I cannot get the car to oversteer. WHether in D/S/M gearbox modes.

i was dying to put an order in for the M3 Touring ... after this weekend, my car has told me a resounding NO

stick to Sim racing ... my local roads are wet, twisty, slippy, nasty surfaces, off camber bends, a recipe for disaster

no motorways, no access to track days ... M340i is the correct vehicle ...

[sikotic]

Never for me while having the traction control on. It seems to just cut the power pretty well that way, but if you turn that off and gas it on a turn it will kick the end out pretty quick and far until you counter

[MontyB1]

I went on a BMW test day a while ago, as part of that they had one part that made you do a circle on a skid pan and floor it. The car continued in a near perfect circle no matter how hard you press or provoked it, until you wound the steering lock off to leave at the right moment the car then went off like a rocket.

Was good to be able to see how much it can do and how controlled it was in safe conditions. Also got to do other brake tests, anti collision and a circuit drive, was really good fun.

[G30M]

i'm thinking this is a M-xxx specific program in combination with heavily rear biased AWD

i can certainly make it lose control (oversteer) in Sport Individual with everything set to comfort. without countersteer and only stepping on the brake the car did not stop the spinning action, it spun until physics (friction of brakes-tires-tarmac) stopped it.

did this repeatedly and easily reproducible. wasn't raining at the time, just wet tarmac.

easily corrected with countersteer. note that it will not break traction in comfort mode no matter how hard i tried.

full stability systems in operation.



but with the DTC was scary it did not cut any power and the car was a wild animal on drugs. even in comfort mode.

[G30M]

if anyone's interested, even in comfort mode in the M4 the car is allowed to oversteer like the M340i in Sport mode.

[arentz07]

RWD 330i M Sport here. In Dynamic Traction mode, on a wet entrance ramp, I could consistently get a little slide going. Pretty entertaining. Ours doesn't even have the limited-slip diff. Ours has the questionable run-flat tires though.

[Montaver]

My 330i xdrive will do a nice 4 wheel drift on power in the wet with traction off. Takes some provoking though.

[dr_frankfurter]

I've managed to break traction a couple times with ESC fully on. Snap into a turn fast enough and it'll let the rear out. Turn into the skid and it's fairly easy to catch, if the ESC doesn't shove you back in line first.
