Bargaining on more diesel interest in the U.S., Mercedes-Benz offers its small SUV with a diesel engine, getting it almost 10 more miles per gallon than its gasoline counterpart.
The GLK-class was launched as a completely new model from Mercedes-Benz just a couple of years ago. The 2013 model represents an update and adds a diesel engine option to the existing gasoline V-6 powerplant.
Mercedes-Benz gives the GLK250 a 2.1-liter four-cylinder diesel engine, which uses twin turbos to produce 200 horsepower and 369 pound-feet of torque. It also gets an average fuel economy in the mid-30s.
