We were able to drive most of the test course in 2WD, which was good. How will you ever know when you really need 4WD if you don’t know what your vehicle can do in 2WD? We drove the course multiple times, taking different lines each time, doing our best to get it stuck. It never happened. The Grand Cherokee suspension consists of a short- and long-arm independent front suspension and a multi-link rear arrangement. An optional Electronic Limited Slip differential is available on V-8 and EcoDiesel models.
