Having owned a launch model in 2000 and having driven this one for a couple of months I can confirm what they have done is massively improve it!
It still has the air suspension, but rather than being a test mule for what became the D3 A8 and some what shonky as a result it is well developed and on the "allroad raised" setting has more ground clearance then the original one, which if I remember correctly was boasted as the same as a landrover!
I doubt you'd go green laning or properly off road in either, but ideal for speed bumps and potholes
