2014 Mercedes-Benz M-Class Review


KBB Expert Rating: 7.0

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. But it's what’s under the M-Class’ skin that really counts. Should the worst happen, a reinforced structure augmented by multiple safety and protection system helps to keep everyone safe. The M-Class can even venture off-road if asked, something not many luxury SUVs are equipped to do.

Most SUVs can promise a quiet interior and a smooth ride, but try and find one that can claim a 174-mph top speed on the autobahn or deliver up enough low-end torque to shame a Chevy pickup. With a 7,200-pound tow rating, the M-Class can actually carry its own weight and then some.

Like everything about the 2014 M-Class but its rather lofty price? Consider a Jeep Grand Cherokee Limited. The two vehicles share a common platform (a product of the former DaimlerChrysler merger) and the luxurious Jeep is equally capable. Those who require seating for seven will also have to look elsewhere.

What's New for 2014

For 2014, a few color and trim changes make up the majority differences from last year’s M-Class crossover SUV. The Sport Styling Package formerly only available on the ML550 is now offered on the ML350 as well.

Driving the M-Class
Driving Impressions

There isn’t a rut, bump or mud patch angry enough to unsettle the 2014 Mercedes-Benz M-Class crossover SUV. Designed to deal with nature’s worst while keeping its occupants cozy, the...

... M-Class is also an enjoyable driver’s car, especially with a V8 under the hood and sport suspension at the wheels. Although not as sporty as the BMW X5, the M-Class nevertheless is no slouch, especially in AMG form. An adjustable suspension allows drivers to choose between a smooth ride or an adventurous one, though we imagine most M-Class owners will leave it in the “comfort” setting. At freeway speeds, we found the M-Class’s cabin thoroughly shuts out wind and road noise, and visibility is pretty good, although we’d still recommend the optional blind-spot monitoring system. Steering feels a tad light at lower speeds and isn’t very communicative overall.

This feature is a lifesaver when your hands are filled with groceries. Just touch a button on the key fob and the tailgate lifts. Closing is equally simple, either via a button on the door itself or with another press on the key fob.

2014 Mercedes-Benz M-Class Details

The 2014 M-Class has all the soft-touch materials and wood accents you’d expect in a luxury vehicle. Leather seating will still cost you extra, but even the base “MB-Tex” vinyl provides an appreciable amount of comfort and good feel. That sensation carries over to just about every other component, from the available wood steering wheel to the tiny gear selector, which bucks the trend by being mounted on the steering-wheel column instead of the center console. Rear passengers are treated to ample legroom, reclining seats and movies of their choice with the optional twin LCD screens mounted inside the front-seat headrests.


Up front is a familiar grille that emphasizes the Mercedes-Benz emblem and sleek headlights that give the 2014 Mercedes-Benz M-Class an appropriately modern look. Adding to the sportier appearance is a sculpted beltline running the sides. The rear benefits from a squat shape and taillights that are stretched horizontally, which give the 2014 M-Class a more sporting instead of utilitarian look. The high-performance ML63 AMG models are distinguished by a larger air intake up front, wider front fenders and quad tailpipes in back.

Notable Equipment
Standard Equipment

All 2014 Mercedes-Benz M-Class SUVs come with a 7-speed automatic transmission, power sunroof, 8-way heated front seats, power liftgate, dual-zone automatic climate control, 7-inch color center display, Collision Prevention Assist and an 8-speaker AM/FM/CD/DVD mbrace2 audio system with weather band and HD Radio. Safety features include nine airbags and Mercedes’ Attention Assist system that monitors for driver drowsiness. ML350 and ML550 versions ride on big, 19-inch wheels, while the top-line ML63 AMG rolls on 20-inchers.

Optional Equipment

Here’s where the M-Class’ $50,000 base price can quickly inflate. Many options are bundled into packages and include navigation, rear-view camera, blind-spot monitoring, adaptive cruise control and a premium harman/kardon Surround Sound system. Further options include a panorama roof, heated steering wheel, heated rear seats and the Parktronic system to aid with parallel parking. The $5,000-plus Dynamic Handling Package makes for a more sporting M-Class with the addition of 20-inch wheels, air suspension and an adaptive damping system. Buyers of the AMG performance version can opt for a package that adds another 32 horsepower and a top speed of 174 mph.

Under the Hood

Each of the four 2014 M-Class models is distinguished by its own engine. At the lowest-priced end is the ML350 with a still-robust V6. Next is the most fuel-efficient of the bunch, the ML350 BlueTEC with a V6 turbodiesel that puts out tremendous power yet yields up to 27 mpg on the highway and a potential cruising range of more than 600 miles. The diesel is 50-state legal and of the “clean” variety, meaning it doesn’t put out the nasty emissions of past diesels, but will require the urea-based AdBlue fluid throughout its life. The ML550 SUV uses a powerful-but-fuel-thirsty V8 biturbo, and the ML63 AMG uses an even bigger, more powerful – and even less fuel-efficient – V8. Even the “slowest” M-Class can accelerate from zero to 60 mph in just over seven seconds, while the AMG version can do it in 4.7 seconds, on par with high-performance sports cars.
