2014 Jeep Grand Cherokee Diesel

The exterior of the Jeep Grand Cherokee is pretty much unchanged for the 2014 model year, but what lands it on this list isn't anything on the outside. It's the 3.0-liter V6 diesel engine that gives the 2014 Grand Cherokee 240 horsepower and 420 lb-ft of torque, while returning an estimated 30 mpg highway when combined with a new 8-speed automatic transmission. This torquey diesel SUV is a winner in our book.
