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 Toyota Avalon

Toyota Avalon Real Gas Mileage: Pros
Year	Comment
2013	The Avalon's EPA ratings of 21 mpg city, 31 mpg highway are the best of any V6-powered large sedan. The Azera's numbers aren't too far behind (20/29). The LaCrosse's are (17/27). In our suburban driving we roughly matched the city figure. On the highway, though, we measured about 27. A number of factors might explain the shortfall. With a 70 mph limit, we were cruising well above the maximum speed of the EPA test cycle. Also, every seat was occupied and the trunk was chock full of luggage. Desire better fuel economy? Well, for the first time the Avalon is also available with a hybrid powertrain, specifically the same 200-horsepower (combined) unit available in the Camry. With this engine, the EPA ratings are 40/39. But you'll give up the more effortless acceleration and sweeter sound of the 268-horsepower V6. While the 3.5-liter V6 has changed very little since its introduction in the 2006 Avalon, and lacks the latest technology such as direct injection, it feels plenty strong and is among the best-sounding V6s. At low speeds and in turns traction is the limiting factor. All-wheel-drive would help, but unlike in the Buick isn't an option. The transmission remains the same six-speed automatic Toyota has offered since 2007. It's smooth and responsive, especially in sport mode (offered with the XLE Touring and Limited). If you desire to call the shifts yourself anyway, this can be done via either paddles flanking the steering wheel or the lever. Econ mode makes top mpg easier to attain by dulling throttle responses and quickening upshifts. see full Toyota Avalon review
