Mercedes-Benz GLK-Class Review

The 2015 Mercedes-Benz GLK-Class ranks 10 out of 14 Luxury Compact SUVs. This ranking is based on our analysis of published reviews and test drives of the Mercedes-Benz GLK-Class, as well as reliability and safety data.

The 2015 Mercedes-Benz GLK-Class is ranked:

Critics describe the 2015 Mercedes-Benz GLK-class as having limited rear-seat space and a rigid ride, but they say it has a swanky interior and the diesel model gets terrific fuel economy.

Test drivers laud the 2015 Mercedes-Benz GLK350 for its standard V6 engine that they say provides rapid acceleration and lots of power. Many reviewers say the available diesel-powered GLK250 BlueTEC offers superior fuel economy and excellent power delivery. With an EPA-estimated 19/26 mpg city/highway, the base GLK350's fuel economy is a bit low for the class. However, with 24/33 mpg city/highway, the diesel-powered GLK250 earns better fuel economy estimates than most rivals. Both models come with a seven-speed automatic transmission that test drivers say shifts seamlessly, and they praise the 2015 GLK-Class’ stable handling and sharp steering. Still, some critics caution that some drivers might find its ride quality to be too firm.

Critics describe the cabin of the 2015 GLK-Class as well-made and built with high-grade materials. They also note that the standard leatherette upholstery feels eerily similar to real leather. Some auto journalists find headroom in both rows spacious and outward visibility good. Others say the GLK-Class' cramped back seat with narrow doors make getting in and out of the vehicle difficult. A few critics also complain that the GLK-Class’ front seats aren’t as comfortable as competitors’. Standard features include a six-speaker stereo, dual-zone automatic climate control, Bluetooth and a 5.8-inch display screen. Mercedes’ COMAND infotainment system with navigation and a 7-inch display, a Harman Kardon stereo system, satellite radio, a panoramic sunroof, a rearview camera, parallel parking assist and blind spot monitoring are optional. Reviewers appreciate the COMAND system’s crisp display, and that stereo, navigation and phone settings can be adjusted with steering wheel controls and dashboard buttons. However, some find the navigation system requires you to scroll through the alphabet and numbers to input addresses, which makes it tedious to use. The climate controls are hard to reach, reviewers say. With 54.7 cubic feet of cargo space, the 2015 GLK-Class’ cargo room is just above average for the class, and reviewers say its low cargo floor makes it easy to load items.

  • “Many of the same high-tech features seen in Mercedes' big-money models are available in the GLK, though mostly as options so as to keep the base price of the GLK attractive to a wider swath of luxury brand intenders. That said, checking off a few option packages can very quickly boost the bottom line by 8-10 grand. The other demerits levied against the Benz include its rather small backseat and cargo areas, and small rear doors that make it difficult for taller adults to get in and out of that rear seat." -- Edmunds
  • "The GLK's 2013 freshening brings some improvements and new safety features that make it a stronger contender in this class. However, one problem remains: Base prices are rather high, and many expected features are extra-cost items that can quickly inflate the bottom line. Still, this luxury 4-door wagon should appeal to buyers seeking brand prestige in a smaller SUV." -- Consumer Guide (2013)
  • "Buyers shopping this segment expect a just-right blend of luxury, comfort and technology. Choose your options carefully, and the Mercedes-Benz GLK delivers ... if you can overlook its quirks." -- Cars.com (2013)

Other SUVs to Consider

The Volvo XC60 has a large cargo hold, and reviewers say it has one of the roomiest rear seats in the class. Test drivers praise the XC60’s nimble handling and powerful turbocharged base engine.

According to reviewers, the BMW X3 offers sporty handling and powerful engines that produce quick acceleration. Additionally, the X3 earns great fuel economy estimates for the class, and critics report that it has a roomy cabin with plenty of cargo space.
