But lower the car with good coils and reduce about 50lbs of unsprung weight at the wheels and you will have a vehicle that handles very nicely.
X-Drive actually is a pretty good balance of performance and inclement weather capability. Looking at how x-drive is engineered, it is pretty close to how Nissan's ATTESA-ETS works. DPC makes another leap towards performance, but simply adding a LSD to the rear will make a more than capable AWD system at the track.
We'll see if there will be a trickle down from the x5m, x6m, and future m5 x-drive to the 335.
