Since the behaviour of the Jeep Grand Cherokee was both dangerous and potentially lethal, we suspected that the car was actually packed with too much weight. We immediately proceeded to weigh the car on a scale and got our answer. The Jeep Grand Cherokee does not have a curb weight of 2 347 kilos (5 174 lbs) that the Swedish certificate of registration indicates (see the attached image below), a figure that Jeep/Chrysler has provided to Transportstyrelsen. In fact, the car actually has a curb weight of 2 505 kilos (5 523 lbs) with a driver in the car. That is a full 158 kilos (348 lbs) more than what Jeep/Chrysler claims the car to weigh in the official documentation provided to Swedish authorities.
Add the 602 kilos (1 327 lbs) that Jeep/Chrysler claims the car being capable to load and the total gross weight is now at 3 107 kilos (6 850 lbs). This can be compared to the claimed total gross weight in the vehicle's registration papers – 2 949 kilos (6 501 lbs). This, again, is a number that Jeep/Chrysler have provided. In other words – if one packs a Jeep Grand Cherokee Overland 3.0 CRD V6 with the maximum allowed capacity, one overshoots the total gross weight of the car by 158 kilos (348 lbs). Worth mentioning is that we only overshot the total net weight by 58 kilos (128 lbs) since we unloaded 100 kilos (220 lbs) out of the car when we performed the test as can be seen in the video clip. The car still went up on two wheels.
Jeep Moose Test Failure
The reason that the Grand Cherokee failed the Swedish Moose Test run by Teknikens Värld is that they unintentionally overloaded the vehicle. Apparently, Chrysler filed the wrong curb weight with the Swedish government.
