Very impressive, but what happened to them doing this in the dock setting?

Maybe it didn't end too well ?!http://youtu.be/EM2GPlwseOc

Come on, it's no where near as good as The Man With The Golden Gun spiral jump from nearly 40 years ago.

Ignoring the Mini PR for a moment, that's a very difficult stunt technically. As soon as the front axle leaves the ramp the rear suspension tries to unload which rotates the car nose-downward. To keep it turning backward needs a big rate of rotation on the ramp (which is very curved: check) and a very stiff rear spring rate (probably, hard to tell from the vid).
This is why most cars land nose-first when you jump them - though I've often wondered why Volvo engineered Mrs T's S40 to land tail-first.
Now, I'm more than happy to be corrected here, but I understood that a vehicle's attitude in mid-air had more to do with the inertia of the rotating masses (engine/gearbox/wheels) than the angle of the departure ramp. This is why most cars land nose-first when you jump them - though I've often wondered why Volvo engineered Mrs T's S40 to land tail-first.
In a nutshell, if you reduce engine revs in mid-air (as most people naturally do), the car tries to rotate about the slowing wheels (and engine/gearbox), due to Newton's 3rd law, that being that each action (the slowing of the wheels) has an opposite re-action (the rotation of the car in the opposite direction). So to land a car on its' tail would simply require a bootful of throttle during the flight (damage to transmission etc notwithstanding on landing).
I was also given to believe that moto-x riders use this principle to control their bike's attitude when going over big jumps.
Might all be an urban myth though.
this was more impressive IMO

each wheel probably weighs more than that "mini"
