TrueDelta Reviews the Real Gas Mileage of the Mercedes-Benz GLK

Mercedes-Benz GLK Real Gas Mileage: Pros
Year	Comment
2013	Fuel economy was a "why not to buy" with the GLK350, as the gas-powered Mercedes-Benz crossover trails the competing Audi and BMW in this area. With the diesel, though, the tables turn. BMW doesn't offer a diesel X3 in North America, at least not yet. For 2014, Audi does offer a Q5 TDI.When I heard that Audi was going to offer a diesel compact crossover, I assumed that the engine in question would be a four-cylinder unit. Nope, it's a 240-horsepower 3.0-liter V6. The official line: a four-cylinder wouldn't suit Audi's performance-oriented brand image in the U.S. With a much smaller engine and (partly as a result) a couple hundred pounds less curb weight, the GLK250 BlueTEC tops the Q5 in fuel economy. But, according to the EPA, only on the highway, with a rating of 33 mpg vs. 31.Both crossovers achieve an EPA city rating of 24 mpg. In the real world, the GLK250 impresses in suburuban driving, with the trip computer usually reporting averages from 31 to 35, and on one run to my son's school nearly 40. This is about 50 percent better than in the GLK350. see full Mercedes-Benz GLK review

Year	Comment
2010	If you prioritize performance, the GLK's mandatory 3.5-liter V6, upgraded via direct injection from 268 to 302 horsepower for 2013, might seem a good thing. But even after the power bump, the boosted sixes in the Audi and BMW are stronger, and they're paired with more responsive eight-speed automatics (vs. a seven-speed transmission introduced nearly a decade ago). More of an issue for most potential buyers: fuel economy. The GLK350 is more efficient for 2013, thanks to direct injection, electric-steering assist, driving style feedback, and a shudder-free automatic start/stop system (study it, BMW). The EPA ratings have improved from last year's 16 mpg city, 21 highway to 19/24. But even 19/24 is only marginally competitive in the 2013 challenge. The BMW X3 xDrive28i is nearly as quick, and rates 21/28. The quicker X3 xDrive35i matches the GLK in the city, but does a couple mpg better on the highway. In our real-world suburban driving, the GLK350 trailed the BMW X3 xDrive28i by one to two mpg. Not a big difference, but a difference. Mercedes will soon offer a more fuel-efficient engine option in North American GLKs. But it won't be a smaller gas engine. Instead, the new GLK250 will be motivated by a 190-horsepower, four-cylinder diesel engine. see full Mercedes-Benz GLK review

2013	4dr SUV turbocharged 168hp 2.1L I4 Diesel 7-speed shiftable automatic AWD	The diesel option was the #1 reason I looked at the vehicule and the deciding point to go with it. At over 200 miles per day to communte, I needed the mileage numbers and in Quebec, diesel is less expensive than regular gas and way less than premium. see full Mercedes-Benz GLK review
2011	4dr SUV 268-horsepower 3.5L V6 7-speed shiftable automatic RWD	better than expected: 19 suburban, 25 highway see full Mercedes-Benz GLK review
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

2011	4dr SUV 268-horsepower 3.5L V6 7-speed shiftable automatic RWD	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

2012	4dr Sedan 300-horsepower 3.6L V6 6-speed automatic FWD	I got 468 miles on a tank of gas from Greenville TN to Charleston SC then to Myrtle Beach. Very impressed see full Chevrolet Impala review
2011	4dr Sedan 211-horsepower 3.5L V6 4-speed automatic FWD	So far so good with E10 Fuel I am getting an average of 27 and I only have 500 miles on it so far.

2009	4dr Sedan 211-horsepower 3.5L V6 4-speed automatic FWD	Averaging 25.0 mpg in mixed driving, very good for the size of the vehicle and the the fact that it is a V6. see full Chevrolet Impala review
2008	4dr Sedan 211-horsepower 3.5L V6 4-speed automatic FWD	Fuel Economy beats smaller sized cars, let alone others in the same class. 30mpg is not hard to attain. see full Chevrolet Impala review
2008	4dr Sedan 211-horsepower 3.5L V6 4-speed automatic FWD	Its a full size car that gives good performance and still gets 30 MPG on the highway. see full Chevrolet Impala review
2008	4dr Sedan 211-horsepower 3.5L V6 4-speed automatic FWD	If driven carefully, 22-30 MPG around town and 33-36 MPG highway. If you are a sloppy driver, make that 18-20 and 25 MPG. see full Chevrolet Impala review
2008	4dr Sedan 233-horsepower 3.9L V6 4-speed automatic FWD	Mileage averages 23-24 around town and close to 30 on road trips which is quite good considering engine size and power. see full Chevrolet Impala review
