look at that. if you dont utilize the body roll for the specific purpose of rolling it, the cherokee is actually quite stable. who knew?

If the vehicle was overloaded and the ESC was turned off (plus I suspect the suspension was in Off Road 1 position - look at the static photos, vehicle looks high when standing and in the turn has tire compression but little or no suspension compression) the vehicle performed particularly well -it did not roll over after this violent and unusual test.
The credibility of the "moose/elk" test is poor, no vehicle fails the initial avoidance manouver but just about all have some instability problems at the violent opposite change back to the original lane. Simply due to the driving procedure - same exit speed as entry (unusual in a similar real world emergency - you would either off the throttle and/or braking) plus the cross arm steering technique gives the driver a lot of leverage in the opposite lock situation. This is why it is used in car rallying ("scandinavian flick technique") and it is designed to unstable the suspension into oversteer.
If it is true that the ESC was disabled and the vehicle loaded beyond its registered GVM then I think Chrysler should sue these turkeys but having some knowledge of the swedish legal system; I would have to wish them good luck.
Just to add I can recall a prominant Swedish car manufacturer was accused of allegedly reinforcing their car bodies in crash testing advertising so horses for courses.

I suspect some of you are mature enough to remember when 60 minutes was rolling the CJ-5 on TV. I owned a 78 CJ-7, and being young and immortal, went out and tried to roll it. Could not even come close. However, if you overloaded it, filled the tires to about 45psi, and really jerked the wheel over hard, you could just get two wheels off the ground. Not close to rolling it over, though.


Also, did a year in New Brunswick Canada and never saw an elk or moose.

The problem is it's Sweden, they have some ridiculous car laws there.

The ESC was not deactivated.

The car was loaded to the specified maximum load, but for this particular version that means it was about 110 lbs over max. total weight. The test was later repeated 11 times at max. total weight, with Chrysler representatives present. The Jeep still rolled up on two wheels, but slightly less. In many of the tests a front tire separated from the rim.

This is not a test required by authorities, but the magazine performs it on all vehicles they review. A tendency to flip over is extremely rare, even for other Jeeps.

I like Jeeps, so don't get me wrong. Let's just get the facts right.

even so there is no reason to go saying its a bad vehicle because of this test. its not a sports car its a suv, if you drove any suv like that you are asking for trouble

Watching that video sent chills down my back. That was the type of maneuver that sent my 2001 WJ rolling. I didn't have the training or the reflexes of that driver in the video so I ended up rolling about 4 times after avoiding a deer (yes, I know, hit the damn thing).

The good thing is that I'm still alive writing this. Since the WJ I owned didn't have a sunroof I'm sure that helped a lot. I'm not sure what would happen if I rolled the WK2.

No, they have tested a lot of SUVs the same way, without incident.

And this is not a maneuver you do for fun. You do it reflexively to avoid an obstacle that suddenly appears in front of you.

The test is believable, but they way he flicks it's coming into the test, it's almost like he's trying to flip the thing. Unless part of this test requires getting back in the travel lane? Although, that doesn't make much sense...



i.e., Why's he still turning in, he's completed the maneuver at this point, right?

Tires look low, first off, we have no idea what else they did to jack it up. I have never had any issue with mine. They may have turned off the esc you do not know... isn't this the country of SAAB ???? socialists anyway...

You could roll and kill yourself with any car or SUV if you turn it hard enough. You've got to be smart enough to just hit the brakes instead of swerving (even if it means hitting the car or deer), depending on the situation, speed, etc.

Maybe for a sports car, yes. Even then, you have 36 ft at 60 mph to do a double lane change, not easy. These tests make me laugh. How can you have the same dimensions / requirements for all vehicles?

Also, how are their reference vehicles even close to comparable? Try using a Land Rover LR3 and see how quickly it flips! That thing looks like a side wind while parked could turn it over. They should have tested an SRT-8 if they want to test a Jeep under a sports car like DOUBLE lane change maneuver. This Jeep has a suspension that is primarily tuned as an off-road vehicle, it doesn't make much sense to compare it to vehicles with suspensions and ground clearances primarily for the street.

Lastly, here's the deal, know your vehicle and driving environment. If you are in a situation where there is a moose, it's likely a rural area, so unlikely to have a lot of on-coming traffic, so, go ahead and serve left to avoid the moose. You will notice the Jeep is fairly stable during the initial maneuver to the left in the video, it's only the quick return that causes problems. So, just take the few extra feet to return to the original lane and no problems. If there is on-coming traffic, sorry moose (and Jeep), and that's why we have airbags (and insurance). And yes, a moose might be big, but I'd rather hit a stationary moose than a semi truck heading at me at 60 mph.

I've had to do evasive maneuvers at 65-70mph, and the GC wasn't even close to rolling. I've taken tight onramps at 60-ish, solid as a rock. The Swedes are just jealous the best car they can produce is a Volvo...
