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

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

2010	4dr SUV 268-horsepower 3.5L V6 7-speed shiftable automatic AWD	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

2013	4dr Wagon turbocharged 140hp 2.0L I4 Diesel 6-speed automated manual FWD	mid 30s in town about 40 so far on trips expect better as the engine breaks in and we take more freeway trips see full Volkswagen Jetta SportWagen review
2012	4dr Wagon turbocharged 140hp 2.0L I4 Diesel 6-speed automated manual FWD	Excellent with the TDI - not sure the gas version. see full Volkswagen Jetta SportWagen review
2011	4dr Wagon turbocharged 140hp 2.0L I4 Diesel 6-speed automated manual FWD	No need to sacrifice mpg to get that power. Have gotten 50 mpg on highway trips of 40 miles. Averaging 39 mpg at fill-ups. Getting 300 miles to half a tank of gas. see full Volkswagen Jetta SportWagen review
2011	4dr Wagon 170-horsepower 2.5L I5 6-speed shiftable automatic FWD	I was hoping for a bit better than the 8+ litres/100 km we are getting with this Sportwagen. I was hoping it would be closer to the 6 l/100 km advertised on the window sticker. see full Volkswagen Jetta SportWagen review
2011	4dr Wagon turbocharged 140hp 2.0L I4 Diesel 6-speed automated manual FWD	Our Sportwagen, automatic, has 17,000 mostly country/suburban miles. We routinely get 43 mpg and the mileage seems to have improved a bit, maybe 2-3 mpg since new. Top mileage is about 47 mph on the interstate, low is about 37 in combined in-town/suburban winter driving. For a car that is fun to drive and responsive at the stop light, this seems very good to me. Right now, diesel is at a premium compared to gas, but we still are saving money on fuel. Mileage on other brands of small wagons was much lower for the same utility. A friend with a new, 2013 Subaru wagon got 30 mpg on a long trip and was happy, but nothing like the TDI delivers. see full Volkswagen Jetta SportWagen review

2009	4dr Wagon turbocharged 140hp 2.0L I4 Diesel 6-speed automated manual FWD	With 32k Miles on the odo, the mileage keeps improving. I think the engine will be fully broken in at about 50k see full Volkswagen Jetta SportWagen review
2009	4dr Wagon turbocharged 140hp 2.0L I4 Diesel 6-speed automated manual FWD	The TDI is a great contender in the fuel economy range. I do alot of driving and it would have presented great savings to me if I was able to located one when I needed to purchase a car. see full Volkswagen Jetta SportWagen review
2009	4dr Wagon turbocharged 140hp 2.0L I4 Diesel 6-speed manual FWD	I was getting around 50 mpg on steady state freeway driving. But the performance was far from economy car- Way better! Can imagine what is possible when the car gets broke in. Excellent all around. see full Volkswagen Jetta SportWagen review

2011	4dr Wagon 170-horsepower 2.5L I5 6-speed shiftable automatic FWD	The Sportwagen's fuel economy is exactly what you'd expect from a fairly substantial compact wagon and a 2.5 litre gas engine, not the magically impossible gas mileage posted on the window sticker at the dealership! see full Volkswagen Jetta SportWagen review
