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 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

2008	4dr Extended Cab 6ft bed 154-horsepower 2.5L I4 5-speed manual RWD	The best so far has been 27 mpg. The worst 19mpg. Average for over 6,000 miles of mostly highway driving has been 23 mpg. At 17,800 miles on odometer the milage is down to 22 mpg. I added 4 new snow tires that have reduced mpg. see full Nissan Frontier review

2013	4dr Crew Cab 5ft bed 261-horsepower 4.0L V6 5-speed automatic RWD	I keep a detailed log of fuel economy. I commute on hour each way, every day. 50% of the time is spent at 65 mph on the highway, and the remainder between 50 and 60 on 2-lane country roads. Only a few stops in between. Very consistently getting 21.5 to 22.3 mpg. I rarely rev it above 4000 RPM - only when passing someone. That happens maybe once or twice per tank. I am underwhelmed by the fuel economy. Full-sized trucks with larger, stronger V8s get similar economy. see full Nissan Frontier review
2011	4dr Crew Cab 5ft bed 261-horsepower 4.0L V6 5-speed automatic 4WD, part-time w/low range	This 2011 Frontier Crew Cab at 4,000 miles is averaging 19-21 hwy, 16-19 city depending on weather and traffic conditions. see full Nissan Frontier review
2011	4dr Crew Cab 5ft bed 261-horsepower 4.0L V6 5-speed automatic RWD	Well it has a 4.0L V6, so I guess I should have expected it. It does have nice power though. see full Nissan Frontier review
2011	4dr Crew Cab 5ft bed 261-horsepower 4.0L V6 5-speed automatic RWD	Well, the EPA ratings are 15 city 20 Highway. The salesman I dealt with says it is easy to get 20 Highway, and I am not an aggressive driver. The V6 is geared low enough that it does 1800 rpm at 60MPH, so my light foot will help here. We will see ! see full Nissan Frontier review
2009	4dr Extended Cab 6ft bed 261-horsepower 4.0L V6 5-speed automatic RWD	Even though it is a powerful V6, economy was on par with much more powerful V8 engines. see full Nissan Frontier review
2006	4dr Crew Cab 5ft bed 265-horsepower 4.0L V6 5-speed automatic 4WD, part-time w/low range	I cant complain about the gas mileage it was around 22mpg when new but with a lift and tires I have sucked some of that away see full Nissan Frontier review

2004	2dr Extended Cab 6ft bed 180-horsepower 3.3L V6 5-speed manual 4WD, part-time w/low range	Average 17/21 during the summer. A friends 96 F-150 (also 4x4) gets 16/20 with a V-8. Expected much better mileage from a small truck. see full Nissan Frontier review
