Excuse me but I believe it is not that simple.
The air suspension in the overland does not appear to be safe. I own a CRD Overland identical to the ones tested and this is my impression after 8.000 miles.
I think we all believed that the suspension is the same as the new Mercedes ML but this is not fully true. The ML has an Active Dampening System which makes the difference from being safe or not.
A shock absorber is meant to mitigate the movement of the chassis and our "Bouncy Lift" suspension does just the opposite.
In the moose test video all
the problem is the way it bounces back when traveling from the first turn to the second. Just focus on this when watching the videos and I am sure you will all agree.
The Quadra lift air units have a good balance in the coil part, but in the shock absorbing one... it is just not valid. This becomes more obvious when you load the vehicle, as the inertia in up-down movement is bigger, and so the shock absorbers are unable to do their work.
More ESP will only brake more here and there, cut more throttle etc. but the problem is not that one. I believe this is why Jeep are so quiet and surprisingly no one out there is pointing out the difference between the air suspension and the standard one.
I am very confident that if the test is repeated exactly but with a standard suspension, everything will be better (have a look on this one from EURONCAP, http://www.euroncap.com/results/jeep.../2011/460.aspx
just below the picture is the link to the videos, it is quite aggressive and the jeep behaves good... but in this case it is equiped with standard suspension and it is still a little bit bouncy at the end of the second run of this test) Of course this Swedish magazine was looking for some extra sales, but they were smart and took an overland with the air suspension for the test. Once you have driven it for a while and have taken some big bumps in highways, your confidence on this suspension is wiped out. It is comfortable and practical, but im my opinion not safe.
Final problem is that with standard suspension it would be very easy and affordable to change the shock absorbers, but with the Air one... no way or just too expensive if you mount the ML ones provided they are compatible (perhaps around 5.000$ and no electronic unit to control the ADS but you could maybe lock them in the sport position)
I believe Jeep do have a problem with this air suspension. So bad that I am sure it will not be silenced just that easy, it will come back to them badly and it is just a matter of time for some overlands to start bouncing and rolling over with families inside.
Everything in my unit is fine but this horrible suspension. This is my first Jeep and will sadly be my last one unless Jeep do care of their customers and come out with a replacement of this air system (imagine the cost… no way they will do that. The sad fact is that from a company point of view many would say there is no viable solution due to the huge cost it would have, so better sail through it or saying “do not overload it… you should all weight your luggage piece by piece when going on a holyday trip, and of course weight all your family and choose who to leave because you are exceeding 100kg…” quite funny
Come-on!! lets be serious and realistic, jeep!!!! not so evidently and politically slippery. It’s a shame.
