We'll see on the towing. One person pointed out to me that the Ford F-150 when through a significant drop in weight (lighter steel, etc.) a while back and actually improved their towing capacity as the engine wasn't needing to pull around as much weight. On the other hand, it is also interesting to note that the Lexus LX570 (the dressed up sibling of our Land Cruiser) only has a towing capacity of 7,000# compared with the 8,100# of the Land Cruiser even though they have the same engine. The LX is heaver by a few hundred pounds. But we suspect it may also have to do with the Adaptive Variable Suspension on the LX. The Discovery will of course also have a pneumatic suspension. I wonder if Land Rover is going to use the new SAE standard J2807 for testing tow ratings as Toyota and a few other manufacturers have done. (LR did not do this for the LR4 which allowed them to continue to use 7,700 for the LR4 even with engine changes as it was mostly a marketing number.) So, the Discovery could be a decent tow vehicle but may be hampered by the air suspension and may have a lower rating if LR use the tests specified by SAE. (I hope they do for the sake of consistency. This would be the time to do it.) It will also be interesting if they embrace the use of weight distribution hitches which are very common when towing trailers over 5,000#. Also, none of these vehicles have a long wheel base do they're never going to be able to go crazy high like a big diesel truck. We'll see. It will be important to see what they tested and not only the max tow weight but also the tongue weight and any caveats or recommendations on the use of anti-sway and weight distribution hitches.
