Re: Jeep Grand Cherokee Moose Test -- Full Story

When I first saw the test I dismissed it as nonsense as there are a lot of factors that are not under control such as how violently the wheel is jerked one way then the other etc but when you take into account that this is happening at only 40mph it is definitly a bit unnerving. Imagine the results at full highway speed?

A few other questions I have would be:

a) How does the V8 do in the test? - does the 300 extra lbs of the motor help or hurt this scenario? In my mind the lower centre of gravity may actually help since the engine sits lower than passengers/cargo in the chassis but I suppose we will never know without another test.

b) How much of a role does tire size and type play here? Considering it has the 20's with a shorter and presumably stiffer sidewall, would the 18" set-ups have the same result? would the extra sidewall flex allow for a less harsh transition between steering inputs? or would the tire be even more likely to pry itself off the rim?

There are so many variables here that its by far an exact science but clearly there is an issue. After watching the follow up video and seeing 6 different tires rip off the wheel even after the Jeep engineers reduced the load I now feel this is something they need to address. Tweaking the stability control/rollover mitigation software should be able to fix this...

Re: Jeep Grand Cherokee Moose Test -- Full Story

I'm strangely more upset at my paint defects and misaligned doors, trim and liftgate than the moose test.

Re: Jeep Grand Cherokee Moose Test -- Full Story

I'm astounded by so many members having blinkers on. The people completing these tests are well respected, and in no way are they fake or staged.

This is an appalling result for a current model passenger vehicle (aimed at families mind!). If the doubters actually watch, listen, and read what they're saying, you'd stop the one-eyed defence of the JGC.

Did you bother to watch the video in the 4th or so post?


I a lot of people know it's possible to get any vehicle to roll and you shouldn't even try a maneuver like this at high speeds unless you're in a lowered sports car. I always tell my wife if a situation comes up where she can't safely avoid an object or car it's safer to just slam the brakes and hit it. Most people would wipe out anyway if they didn't roll and go into a spin when doing this at high speeds.

I concur, I came from an e46 m3 on coilovers and the car would absolutely handle this maneuver with no issue. Do I expect the Overland to? Absolutely not. I would be hard on the brakes first, then make the attempt to swerve away from the "moose". I would expect most people would make the same split decision. The manuever in the video would either put you in the lane of oncoming traffic or in to the shoulder if there even is one. I'll take my chances with the moose

Re: Jeep Grand Cherokee Moose Test -- Full Story

Here's a BMW X5 that flipped itself in Alexandria, Sydney Australia today. There was no moose involved, and there was no other car involved, and it was a straight piece of road in an industrialised area.

I guess the point is that any car can be flipped if you are inattentive enough or if you go out of your way to do it.

A moose is just one example but many moose accidents kill the driver because of the center of gravity thing. The moose legs are just long enough that the body is over the hood and comes crashing through the windshield, even at relatively low speed. If you are going to hit a moose, try not to hit it dead on.... and even rolling the vehicle may be a safer option for you. Any other animal common in North America is not as much a safety hazard, but those pigs are solid, hitting one of those is like hitting a granite wall.

Re: Jeep Grand Cherokee Moose Test -- Full Story

You guys who says "Hit the moose", obviously know nothing about moose accidents. Do a google image search for "moose crash" and you will know why it's better to swerve than to not....

And you guys who says it didnt even roll one single time.... Well take a good look at the road conditions where this test was performed. Then imagine your traction control failing like that on lets say a snowy, rainy or muddy road....

This is not about buying or not buyng a WK2 because it failed this test. This test shows there is a fault with the vehicles handling and many people now days wants a good and safe car in a matter to avoid accidents. And with todays security standards in SUV's or cars... this is unacceptable. If you say otherwise you are probably married to your cousin or something...

Re: Jeep Grand Cherokee Moose Test -- Full Story

my opinion of this, not knowing anything about "the moose test" til I read this (or about the group doing the testing).. The thing that seems fishy to me is that after the initial test, they retested with what...4 vehicles? Blew out 6 tires? It's almost as if they're going above and beyond to show that there is a problem. They showed the failures but do we know how many times they made this run without problems? Editing is a wonderful thing..

At the most basic level, if that testing is what you do and then you get questioned on the results, wouldn't you really want to prove that you're right? After the reaction to the initial testing, it's in their best interest to show the Jeep fail. Just my 2 cents..

why do you guys think you need to make your point by throwing out insults to those who disagree? I see no fault with that test or vehicle. It was an emergency manuever and the jeep did not flip. I see that as good IMO. This is just another chance for you WK guys to bash what you dont like. Straight up truth. And WTF do you care if I was married to my cousin? LOL

Re: Jeep Grand Cherokee Moose Test -- Full Story

So let me get this straight. If I am traveling down the highway in a heavy SUV with high ground clearance and all season highway tires and make a very abrupt lane change maneuver, it will not handle like a lowered sports car? Say it ain't so!!!

I don't even expect the JGC to handle as good as our MDX. It also has some weight, but it's not as high and has a sport suspension.

Now, if that video had featured an SRT, then it's a different story.
