The biggest change for 2014 will be the availability of a 3.0-liter diesel V6, which we previewed just over one year ago. In the European Grand Cherokee, this engine produces 241 horsepower and 406 pound-feet of torque – seriously good power numbers for Jeep's stalwart utility vehicle.
Additionally, Automotive News reports that a ZF-sourced eight-speed automatic is on deck for 2014. Details are scarce right now, but this transmission will likely be paired with the 3.6-liter Pentastar V6, just like in the 2013 Ram 1500 and the current Chrysler 300 and Dodge Charger.
The 2014 Grand Cherokee is slated to debut in January, likely at the Detroit Auto Show, with sales to start shortly thereafter.
