The venerable Grand Cherokee is entering the tenth and final year of its fourth generation. A completely redesigned model is due for 2021. In the meantime, a few revisions were made to the equipment and finishes to maintain consumer interest. In addition to the standard 3.6-litre Pentastar V6, you can opt for a 5.7-litre or 6.2-litre HEMI V8, the latter featuring a supercharger and unleashing 707 horsepower in the Trackhawk model. Maximum towing capacity is a segment-best 7,200 pounds.
