MDM and 4WD Sport

harperium · 09-07-2021, 08:39 AM

All my BMWs have had xDrive, and I haven't driven a RWD car in this century.

That said, and this may be a placebo effect, but yesterday I was out having fun and put the X3MC in MDM and then in DSC-off-4WD-Sport mode, and I could swear the car felt differently when cornering under throttle. I wasn't going hard enough to get the back to slide out, but it felt like less power was going to the front and thus I wasn't feeling the AWD feeling of the front wheels digging through a sharp turn.

Or is this totally my imagination?

4WD Sport makes it nearly RWD. Careful because that back end will definitely try to come around if traction slips. I had one moment which I don't care to talk about

Regular 4WD is still rear biased quite heavily.

I find the traction control reigns things in pretty quickly if the rears break traction.

I need to find an empty parking lot and play around with this.

Really? When I'm in MDM mode it will let me swing the back out pretty far without intervention.

agree - needs a lot of intervention. I have been caught out.

For this reason I'm going to leave mine of 4WD.
