Would Your Car Pass the Moose Test?

The possibility of hitting amoosewhen you're driving aroundSwedenis no joke. So Swedish car makers have been performing the Moose Test on their new vehicles for decades. Other automakers eventually adopted the tough evaluation, too, which today is credited with being the impetus for better stability control systems in vehicles around the globe.

What Is the Elk Test?

The dry-surface car test, aka theElk Test, is straightforward. The vehicle being evaluated quickly swerves into the left lane — as if to avoid an object in his own lane — and then immediately swerves back into the right lane to avoid oncoming traffic. The test is repeated at faster speeds until the vehicle knocks over cones, spins out or flips over. The faster you can go and still maintain control, thesaferthe vehicle.

In the 1970s, Swedish automakers began conducting various forms of theEvasive Maneuver Test, as it was originally called, to protect drivers from animals such as wild boar, arctic foxes and, yes, moose, which often step onto the road in front of drivers. Moose are a particular danger because of their size; their shoulder height ranges from 5 to 6.5 feet (1.5 to 2 meters) and they can weigh a hefty1,800 pounds(816 kilograms).

Who Came Up with the Moose Test?

The name "Moose Test"came fromSwedish journalist Robert Collin in 1997, when he flipped a new Mercedes-Benz while performing the test — which he later likened to a maneuver one would make to avoid hitting a moose at a high speed. Mercedes-Benz modified the car's suspensions and made its Electronic Stability Program (ESP) standard for the vehicle model.

Soon major automakers and customers were paying attention to stability features. Eventually the European Union, Australia, Canada and the U.S. made the stability control system mandatory in all new cars. Yet despite its importance and popularity, the Moose Test is sometimes controversial.

When the 2012 Jeep Grand Cherokeeflippedduring a test conducted by Swedish magazine Teknikens Varld (Technology World), manufacturer Chrysler claimed the Swedish magazine overloaded the vehicle and said its own Moose Test was successful. Other automakers, when faced with poor Moose Test results, have claimed it was due to the fact that testers altered the conditions or said the results were inconclusive.

Which Car Has the Best Moose Test Rating?

哪一辆车是顶部the Moose Test rankings? The1999 Citroën Xantia Activa, which hit 52.8 mph before losing control, unbelievably, still holds the record for the all-time fastest speed reached to complete this infamous test. Back in the day, all Citroëns had a self-levelling hydraulic suspension versus the then-conventional springs and shock absorbers. And the Citroën Activa contained a Cadillac version of this suspension, allowing it to ride quickly and tightly through corners.
