Just found this on you tube. I thought it was a pretty impresive demonstration the Disco 2 Land Rover towing.
Shows the Electronic Brake Force distribution
Mines the last of this shape. It's got a bunch of fancy tech under it. Self leveling suspension, a hydraulically actuated front sway bar and a sophisticated traction control system being the main ones. It corners very flat since the front sway bar stiffens up as you steer into the corner. It was very surprising the first time I drove it. Also when you go off road the sway bar disengages completely for maximum suspension articulation.
The traction control system uses the brakes to lock spinning wheels and transfer drive to the wheels that have traction. It was pretty revolutionary in it's day.
The Self leveling rear suspension detects how much load there is in the back and adjusts the rear air bags to suit. This is handy if you hook a trailer on as the draw bar height doesn't change.
But I wouldn't reccomend one now. The last person I recommended one to has had nothing but trouble with it.
