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 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

TrueDelta Reviews the Real Gas Mileage of the Acura MDX

Acura MDX Real Gas Mileage: Pros
Year	Comment
2014	In addition to trimming the size and weight of the MDX, Acura also reduced the size of the V6 engine from 3.7 to 3.5 liters. Thanks to direct injection the new, smaller engine is nearly as powerful (290 vs. 300 horsepower), and is even a little punchier at low rpm. It can run on three cylinders to save fuel while cruising. The QX60's V6, also 3.5 liters, lacks direct injection and is only good for 265 horsepower. Even though the Infiniti's CVT (continuously variable transmission) can hold the engine at its power peak, this isn't enough to compensate for its power and weight disadvantages. The MDX is noticeably quicker, if still not thrillingly quick. (It can get to 60 mph in about seven seconds.) Then again, fuel economy appears to have been the priority. In the EPA's tests, the 2013 MDX rated 16 mpg city, 21 mpg highway. Infiniti, aiming to top these marks with the JX35 did so by two mpg (18/23). A redesigned CVT shared with the new Nissan Pathfinder bumps the QX60 to 19/25. The new MDX trails the Infiniti by one mpg in the city, but tops it on the highway with a 27 mpg rating--tying the new diesel BMW X5 and impressive for a gas-powered three-row crossover. In real-world suburban driving with an economy-minded right foot the trip computer reported averages from 21 to 23. With a feather-light foot and good luck with traffic lights, 25 can happen. Drive the MDX hard enough to enjoy the snarl that kicks in with the big VTEC cam lobes at 5,000 rpm, on the other hand, and mpg falls into the mid-teens. Highway driving confirmed the EPA estimate. see full Acura MDX review

2012	4dr SUV 300-horsepower 3.7L V6 6-speed shiftable automatic AWD	Gas mileage is not good. The best I get is around 20 mpg, and use 91 octane as reccommended. I've tried mid-grade 89 octane with no noticable difference but for $1.00-$2.00 per tankful, I'm choosing to stick with what is reccommended. It would be nice to have a front wheel drive only version which would save on gas, but it's not offered. see full Acura MDX review
