5.0 speced out to my likes = 75,525
3.0 speced out to my likes = 67,975
Diesel speced out = 71,025
I would have to drive it. I honestly never considered it.
I just found this onfo on the D:
The X5 xDrive35d turbodiesel is still offered for the 2011 model year, and despite increased competition remains the fastest and most fuel efficient diesel-powered vehicle in its class. The vehicle’s 265 horsepower and 425 pound-feet of torque see it reach 60 mph from rest in 6.9 seconds..
Other than the torque it's slower than the 3.0 in 0-60..
