2010 Mercedes-Benz GLK Real Gas Mileage: Pros

2011 4dr SUV 268-horsepower 3.5L V6
7-speed shiftable automatic AWD
A major disappointment. But, to be fair, I live at the top of a mountain in LA and all of my past cars also had bad mileage. It isn't bad on the highway...I get average of 22 mpg...but pure city driving drags it down to 16-17. see full Mercedes-Benz GLK review

having owned a c280 with 3 liter engine and been very happy with performance plus low 30s highway, mid to high 20s suburban, why not put 3 liter in the glk? while glk is heavier, 3.5 liter penalizes mpg for little better performance. otherwise there is nothing not to like and alot to like about this great vehicle. see full Mercedes-Benz GLK review

Performance comes at a price...gas mileage more on the order of a full size SUV. Wish a diesel had been available. see full Mercedes-Benz GLK review
