Mercedes-Benz M-Class Review

The 2014 Mercedes-Benz M-Class ranks 6 out of 18 Luxury Midsize SUVs. This ranking is based on our analysis of published reviews and test drives of the Mercedes-Benz M-Class, as well as reliability and safety data.

The 2014 Mercedes-Benz M-Class is ranked:

Test drivers praise the 2014 Mercedes-Benz M-Class for its powerful engine choices, luxurious cabin and composed ride, though some rivals offer more standard features.

Automotive writers say the 2014 M-Class has ample power, regardless of which trim you choose. The M-Class’ engines include a V6 in the base ML350 and a turbodiesel V6 in the ML350 BlueTEC, as well as twin-turbocharged V8 engines in the ML 550 and the performance-tuned ML63 AMG. Reviewers are most impressed with the ML350 BlueTEC, saying it offers a great combination of fuel efficiency and rapid acceleration. Models equipped with V8 engines guzzle more gas but they’re shockingly fast, they add. All trims come with a seven-speed automatic transmission with paddle shifters. The ML350 gets an EPA-estimated 18/24 mpg city/highway, which is very good for the class. The ML350 BlueTEC gets 20/28 mpg city/highway, which is superb for the class and comparable to what other diesel-powered SUVs in the class get. Most reviewers say the M-Class handles well, with accurate steering and strong brakes. But some say that competing SUVs are more agile, and the steering doesn’t offer much road feel. Still, most test drivers report that the M-Class offers a comfortable ride.

Test drivers are impressed with the Mercedes-Benz M-Class’ cabin, saying that premium materials and quality construction make it feel luxurious. The front seats are comfortable and set high for good visibility, they report, adding that the back seat is very spacious with a generous amount of legroom. The M-Class comes standard with a power sunroof, Bluetooth phone and audio connectivity, a USB port, a COMAND infotainment system, a six-disc CD/DVD player and an SD card reader. Options include navigation, a rearview camera, active lane keeping assist, park assist, a rear-seat DVD entertainment system, a panoramic roof and heated and cooled front cup holders. The COMAND infotainment system is controlled by a knob on the console rather than a touch screen. Some critics say the system is confusing and requires time to master, while others write that it’s easier to use than the systems in rival SUVs.

  • "If sporty performance is a top priority, the 2014 Porsche Cayenne is a breed apart, while the 2014 Acura MDX and Lexus RX 350 are also quite appealing, and less expensive to boot. But for those who prefer to cruise in dignified comfort, the 2014 Mercedes-Benz M-Class is bound to satisfy, as long as you don't need a third row.” -- Edmunds
  • "While the 2014 Mercedes-Benz M-Class certainly has appeal as a rolling status symbol, in truth there is so much more to the M than just the iconic 3-pointed star on the hood. With a robust lineup, including diesel power and a high-performance AMG model, the M-Class demonstrates an ability to be all things to all customers." -- Kelley Blue Book
  • "The M-Class has long epitomized the midsize luxury SUV segment, but the competition is always working hard to catch up. With the 2014 Mercedes-Benz M-Class on the scene, those competitors must once again bring strong contenders to stand a chance at matching this SUV's strengths.” -- AutoTrader
  • "The Mercedes-Benz M-Class is very refined, solidly built, and pleasant to drive. High points include the comfortable, well-finished interior and excellent powertrains. Think of the ML63 AMG as a suede- and leather-lined cruise missle. It commands a significant price premium, but it is arguably the most well rounded high-power luxury SUV on the market with its admirable blend of performance, comfort, and refinement." -- Consumer Guide (2013)

Other SUVs to Consider

Reviewers say the Porsche Cayenne has athletic handling, communicative steering and is one of the most engaging SUVs to drive in the class. Test drivers also praise the five-seat Cayenne for its opulent interior and say that its dashboard controls are easy to operate.

If you need more passenger space, look at the Acura MDX, which seats seven in three rows. Reviewers say the MDX offers snappy handling while maintaining a comfortable ride. Features that cost extra in the M-Class, including leather upholstery and a multi-view backup camera, come standard on the MDX.
