Was in the same predicament as you. Opted for RWD and couldn't happier as it comes in Manual.

I also live in Canada and get major snow.

Nothing my winter tires can't handle!

Hahaha... I'm certainly not burying myself.

The BMW Xdrive provides 40/60 power (F/R) in typical driving conditions. And it has the ability to drive when 100% of torque is shifted to one axle in slip conditions. I don't know what the thinking is when it's equated to one wheel or even two (LSD) to better traction than the Xdrive.

I indicated in my post that "All other things being equal" and yet, there is continued reference to tires and more. Lmao! I know the value of tires, compounds and contact patch, etc. But that's not what we're talking about. It's a simple comparative to two different traction systems, and the increased traction of one, over the other.

There is no way in any event, that a rear drive alone is superior to an Xdrive in regards to traction, straight, in turns, wet, or on snow. Because the worst an Xdrive system can do, is step down to the other, but the single or LSD cannot shift torque to the wheels that are not spinning whereas the Xdrive can.

Otherwise, I'm always open to being educated. School me where I'm mistaken.

The only possible traction advantage an LSD could have is if the front axle had zero traction in a turn and the traction between the two rear tires was uneven. The xDrive would then behave like a standard open differential RWD car, while the LSD would behave like a RWD car with LSD.

The odds of such a scenario occurring are 0%, considering it is physically impossible to turn (or to continue turning if it happens mid-corner) if there is zero traction in the front wheels.

I knew yours was sarcasm. Guess my joke went right over your head. I even added a lol....
