About the 2014 Mercedes-Benz GLK-Class
1st generation GLK-Class (X204, U.S. market 2010-2015), second year after the major 2013 refresh.
Mercedes-Benz positions the GLK-Class as a compact luxury SUV that blends upright SUV styling and everyday cargo flexibility with the road manners and cabin finish of one of the brand’s sedans. In 2014, its core appeal is choice: the GLK 350 offers quick V6 performance, while the GLK 250 BlueTEC leans hard into diesel torque and highway efficiency. Across the lineup, Mercedes emphasizes safety, solid road feel, and a premium interior over outright family-room space.
The GLK 350 is the quick gas-powered version, with a 302-hp V6 and rear-wheel drive; the GLK 350 4MATIC adds all-wheel drive for better traction in poor weather. The GLK 250 BlueTEC 4MATIC pairs standard all-wheel drive with a high-torque diesel engine rated at up to 33 mpg on the highway. All three use a seven-speed automatic and have a 5.8-inch infotainment display with Bluetooth audio streaming.
