I am planning to buy my next SUV either later this year or early next year and am considering an X5 Diesel. I've read conflicting feedback from owners about it's towing capabilities. While it's rated by BMW at 6,000 pounds I would think it can tow much more given the amount of torque it produces; 2013 X5 Diesel produces 425 Lbs vs. 417 from a 2013 Cadillac Escalade which is rated to tow ~8,500 pounds.
I would be towing my 2012 e92 M3 with an open trailer for now but might use an enclosed trailer in the future, which could drive the combined weight to more than 6,000 pounds.
Any advice or experience is appreciated.
