...trust me...I tried everything to make my ML55 roll over but I didn't succeed.
I can give you some reasons:
1. tires: the tires the ML55 uses are not that "stiff" to avoid the car providing too much sidegrip which could result in a roll over on a SUV
2. extreme understeer setup of the suspension: the front tires start to understeer pretty early to avoid letting the light rear brake out or create instability
3. suspension setup: the suspension on the ML55 is pretty stiff, almost uncomfortable to eliminate side roll almost completely. The swaybars are huge.
4. ESP: the ML55 has a very good ESP setup which provides a lot of safety. Even in winter time or on wet streets, I couldn't get instability, no matter what I did.
5. the steering: steering is pretty indirect on the ML55. Almost like on a real truck. This helps to avoid sudden steering wheel moves which would result in possible instability.
One gets pretty fast used to it and I already adopted a certain method to be able to steer in more directly without provoking ESP activation or instability.
I would even speculate that an ordinary Boxster driver would have problems to follow me...and I'm not talking about the Autobahn.
SUVs are the only cars which have a sales increase over here in Germany. People started to love them and I think it will be pretty similar as in the US in a few years.
I know there is a anti-SUV sentiment growing in the US right now but maybe because some SUV manufacturers didn't build the right SUVs in the past. I rented a Lincoln Navigator for my march 2002 Florida vacation. It doesn't even come close to the ML55's driving abilities but it still is a pretty safe car. Couldn't make that baby roll over either (Hertz is very happy about that
).
My advise: as soon as the Cayenne hits the dealers, get one for a one day testdrive. I'm sure you'll be surprised.
A last word: I also owned a Isuzu Trooper many years ago. This thing was horrible and I'm sure that it would have been easy to put it upside down. But I neither had the gutts nor the experience to drive this thing fast by that time. Lucky me.
