Two SUVs with some similarities, but otherwise different in most aspects such as the model year, horsepower, fuel economy, ground shadow size, and maximum occupancy. First of all, the 2014 Durango has a more powerful engine and gets 3 mpg less than the 2016 Grand Cherokee. Also, the body structure of Durango is slightly larger than that of the Grand Cherokee. In addition, you'll seat two more passengers in the Dodge Durango than in the Jeep Grand Cherokee. Among similarities are the body structure, market segment, starting price, and height.
