To καλοκαίρι του 2012, το Σουηδικό Teknikens Värld δοκιμάζοντας το Jeep Grand Cherokee είχε κάνει και τη δοκιμή αλλαγή πορείας (Moose Test) ενώ κινούταν με 63.5 χλμ/ώρα. Τότε το Grand Cherokee εξέπληξε δυσάρεστα τους Σουηδούς αφού σηκώθηκε στις δύο ρόδες.
Το θέμα είχε ανοίξει “πόλεμο” ανάμεσα στην Chrysler και στο Σουηδικό μέσο, με την εταιρία να κατηγορεί τους Σουηδούς ότι τα Cherokee που δοκίμασε ήταν υπερφορτωμένα κατά τη διάρκεια του test.
Τώρα οι Σουηδοί θέλησαν να κάνουν το ίδιο τεστ με το ανανεωμένο Cherokee, το οποίο αυτή τη φορά πέρασε τη δοκιμασία χωρίς απολύτως κανένα πρόβλημα.

This is how the new Jeep Grand Cherokee 2014 handles the moose test
Perhaps you remember Jeep Grand Cherokee in Teknikens Värld’s moose test summer 2012? The car went up on two wheels and was about to roll over. The dangerous behavior in the avoidance maneuver quickly became world news. Now we take the new Grand Cherokee, model year 2014, to the moose test track to see if it is better than its predecessor.
In summer 2012 the previous generation of the Jeep Grand Cherokee went up on two wheels in Teknikens Värld’s famous moose test. Already at low speed, 61 km/h (37.9 mph), the wheels on the inside left the ground and at 63.5 km/h (39.5 mph), the car was about to roll over. Neither did the electronic stability system or the anti-rollover system respond – very strange.
We repeated the tests, with different drivers and different Jeep Grand Cherokees, but the result was always the same. Except when Jeep’s American engineerers had been given access to the cars and the tests were run on their premises – then the result instead became seven front wheel punctures.
You can read all about the moose test behaviour of the Grand Cherokee in 2012 at teknikensvarld.se, where you also find the film that has been seen by over 2.5 million people worldwide.
In Teknikens Värld issue 2/2014 we test the newly updated Jeep Grand Cherokee 3.0 CRD model year 2014, where it is compared against the new BMW X5 and Range Rover Sport. With summer tires mounted and the cars loaded according to their Swedish certificate of registration, in the case of Jeep Grand Cherokee a total weight of 2 949 kg (6 501 lbs), passengers and luggage included, we go for the test track.
We are delighted to point out that our test results from 2012 have led to a comprehensive development work by the Jeep engineerers, the old behavior is completely gone. The main difference is that the traction control system begins to work really early and it slows down the speed of the car dramatically, even at such low entry speed as 61 km/h (37.9 mph). When we increase the speed the system actually works even more, making the behavior of the car just as safely as it would have been that early summer day in 2012.
At 71 km/h (44.1 mph) the car reaches its limit, the car cannot master more than that. But it is a good result for a SUV vehicle, no doubt about that. It is also a clear sign that Jeep understood the seriousness of the previous generation’s severe flaws and did something to it.
