The 2016 Mercedes-Benz GL-Class is for those wealthy among us that want a full-size ute that has enough power, plush, flamboyancy and practicality. This vehicle is for 7 passengers, its 5-door, can tow a max of 7500lbs with proper equipment, and allows 93.8 cu ft. of cargo space with rear seats folded and the third row seating is ample enough for adults. There are some rumors from Germany that a renewed version of the GL-Class, called the GLS, is on the drawing board. This new and upgraded version of the GL-Class is expected to offer improved mbrace2 infotainment, a clearly restyled profile, a redesigned dashboard and center stack, and a few minor changes to the current engines. Some reviewers claim there will be a late-2016 debut for the GLS. Truth be told, the scarcity of reliable information about this upgraded GL-Class leads one to believe that the 2017 model year seems a more appropiate release date. In the meantime, look out for the 2016 GL-Class trims include the entry-level GL350 BlueTEC and the GL450, the up-featured and up-powered GL550, and the track-tested GL63 AMG. The latter remains a product of M-B’s AMG racing division. Also for the upcoming year, all GL-Class iterations come with standard iAWD so each carries the winter and terrain-taming 4Matic designation. Engine for the unchanged GL350 BlueTEC remains a 3.0-liter turbodiesel V6 that’s coupled with the returning 7-speed shiftable automatic transmission. This engine produces 240 hp and a whopping 455 lb-ft of torque. Fuel efficiency slated to equal the current 19/22/25 mpg. If you select taking the 2016 GL450 home when it decorates dealer showrooms in the late summer of 2015 you will then get a gasoline-fired 3.0-liter turbocharged V6 that is again connected to the ubiquitous 7-speed shiftable automatic. This peppy force-fed V6 engine throws down 362 hp and 369 lb-ft of torque, to the tune of 17/21/17mpg.Same as with all the GL-Class non-diesel trims, this potent 6-cylinder is equipped with standard stop/start technology that shuts down the engine at a stop and restarts it when the gas pedal is pushed. Excellent for traffic jams. Going up a level to the 2016 GL550, you can find a 4.6-liter twin-turbocharged V8 mill along with the traditional 7-speed shiftable automatic transmission. Expect the 429 hp and 516 lb-ft of torque from this V8-led with fuel economy slated to remain 13/18/15mpg. At the top of the powertrain heap, we have the race-inspired almighty GL63 AMG, with its standard – but still impressive- 550-hp 5.5-liter V8 engine and its sport-tuned 7-speed shiftable automatic. Expected to produce out 560 lb-ft of torque, this puppy won’t pass up many gas pumps with its 13/17/14mpg fuel economy estimates.
