2012 Mercedes-Benz GLK Class Fuel Economy

5.0
Fuel Economy

Gas mileage is one of the reasons luxury-ute buyers have steered away from larger vehicles, but the Mercedes-Benz GLK might give them pause.

By the measuring tape a compact crossover, not a mid-sizer even, the GLK may drive like a smaller vehicle, but it gets fuel economy ratings of a larger SUV. The V-6 and seven-speed automatic combine for an EPA-rated 16/23 mpg on rear-drive models, which drops to 16/21 mpg on all-wheel-drive models.

With its mid-size gas mileage, the compact Mercedes-Benz GLK could really use the long-awaited diesel option.
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.
