Jeep Trail Rated
All 2011 Jeep Grand Cherokees equipped with either the off-road or the Quadra-Lift group are Trail Rated®. The Jeep Trail Rated badge on the 2011 Jeep Grand Cherokee indicates that the vehicle has been designed to perform in a variety of challenging off-road conditions identified by five key consumer-oriented performance categories: traction, ground clearance, maneuverability, articulation and water fording.
Jeep Trail Rated is a unique methodology used by Jeep Engineering to measure and predict off-road performance for all Jeep vehicles. Through a combination of natural and controlled field tests, Jeep Trail Rated provides a consistent measurement of off-road performance for all Jeep vehicles. Only Jeep vehicles are Trail Rated.
