2011 Mercedes-Benz GLK Class Fuel Economy

5.0
Fuel Economy
The 2011 Mercedes-Benz GLK is really a compact—not mid-size crossover wagon—yet it has the fuel-economy ratings of a mid-size or larger ute. Whether you get the GLK350 with rear-wheel drive or the 4Matic all-wheel drive system, it's rated at a not-at-all-green 16 mpg city, and highway ratings are either 21 or 23.

Part of the issue, of course, is that the GLK only comes in GLK350 guise, with its comparatively large-displacement V-6. And it's quite heavy. Mercedes-Benz has suggested that it is considering adding a four-cylinder turbo-diesel model to the GLK lineup in a future model year, but no official announcements have yet been made.
