Edmunds' Expert Review

It may not be the roomiest or the most fuel efficient, but the 2010 Mercedes GLK350 is an impressively built compact crossover SUV that should meet the needs and desires of many luxury buyers.

Vehicle overview

Mercedes-Benz was one of the first players in the luxury SUV market, but until now, the compact segment of that market had been ignored by the three-pointed star. Correcting that problem is the all-new 2010 Mercedes-Benz GLK350, a compact crossover that combines elements from throughout the brand's lineup. Based mechanically on the C-Class sedan, but boasting blocky styling aped from its bigger GL- and G-Class siblings, the GLK is like a greatest hits album with one or two new tracks up its sleeve.

The 2010 GLK350 is the second-cheapest Mercedes you can buy in this country, but you'd never suspect it. The GLK is built to such a high standard that its price premium over most similarly equipped competitors seems well worth it. Close the GLK's doors and the sound they emit gives the feeling of closing a bank vault -- all that's missing is that spinny wheel thing. Go over railroad tracks and the body doesn't flex a bit, nor does any jarring or jiggling greet your backside. This little SUV feels like you could drive over a grenade and experience nothing but a muted "thump." The GLK350 may not be perfect, but when it comes to meticulous build quality, it simply has no equal in this segment.

Drive the GLK back-to-back with a C-Class sedan and you're bound to get a sense of déjà vu all over again. In addition to its aforementioned ironclad feel, the GLK's steering and ride are remarkably similar to the C's. Not surprisingly, the GLK is built using a C-Class platform that's been shortened by 4 inches and given some appropriately pumped-up SUV ground clearance. The GLK and the C350 share the same 268-horsepower 3.5-liter V6 engine, which in the GLK is the only power choice (a Bluetec diesel option should be available in future model years), while the seven-speed automatic is the lone transmission.

The interior is also a chip off the ol' C-Class block -- and we do mean block. The controls are virtually identical, but they're placed on an upright dash with nary a curved surface in sight. When done up in black, the GLK's austere cabin is the most stereotypically Germanic environment short of the Hofbräu tent at Oktoberfest. What it may lack in flair, though, the GLK interior more than makes up for with superior materials and impeccable fit and finish. Mercedes' interior quality took a nosedive for a few years, but the GLK's quality construction proves that the three-pointed star represents a world standard once again. The rather haphazard electronics interface is less impressive, but we do like it better than BMW's iDrive system.

The GLK does have a couple downsides, however. Its maximum cargo capacity and rear leg room are on the low side among luxury SUVs, so if you're looking for a hauling machine, you should probably look elsewhere. The Volvo XC60 provides just enough of that extra utility to make it more appealing to families, while the Lexus RX 350 is also about the same price and a full size larger. If the size is right, but you want something a little more stylish and sporty, the Audi Q5 is also worth consideration. The Acura RDX and Infiniti EX35 would be cheaper choices that offer a more dynamic driving experience.

However, even if the 2010 Mercedes-Benz GLK350 may not be the cheapest, biggest or most fun to drive compact luxury crossover, it's so well-rounded that finding glaring faults is difficult. We think buyers will find it a compelling choice and will be pleased to discover that Mercedes is once again at the top of its game.

2010 Highlights

The 2010 Mercedes-Benz GLK-Class is an all-new compact luxury SUV.

Performance & mpg

The 2010 Mercedes GLK350 is powered by a 3.5-liter V6 good for 268 hp and 258 pound-feet of torque. A seven-speed automatic transmission with comfort, sport and manual settings is standard. Rear-wheel drive is standard, and all-wheel drive (known as 4Matic) is optional. In performance testing, a GLK350 4Matic went from zero to 60 mph in 7.2 seconds. Estimated fuel economy is 16 mpg city/21 mpg highway and 18 mpg combined with 4Matic. Sticking with rear-wheel drive nets 1 mpg better on the highway.


The GLK comes standard with stability control, antilock disc brakes with brake assist, front-seat side airbags and side curtain airbags. A rearview camera, parking sensors and TeleAid emergency telematics are optional.


The 2009 Mercedes GLK's most notable driving characteristic is the rock-solid feel of its chassis and unibody construction over every bump and road imperfection. The ride may be on the firm side for some (that some should buy a Lexus), but all others will appreciate the way the GLK350 confidently glides over the road. Through corners, the GLK remains securely planted despite its top-heavy nature, and its steering is well weighted and offers respectable feedback. We wouldn't describe the GLK as particularly fun compared to the X3 or EX35, but its dynamics are bound to please its likely clientele.

The V6's 268 hp is more than adequate -- the GLK's acceleration isn't breathtaking, but the dual exhausts give off a pleasant Germanic growl during aggressive driving. On the highway, the V6 is remarkably quiet, emitting an almost imperceptible purr. The seven-speed transmission is remarkably smooth -- even in sport mode -- but it can be a bit slow to downshift at times.


The GLK's cabin looks like its designers stuck exclusively to rulers -- there's barely a rounded edge to be found. While this produces a rather austere and stark environment (particularly in black), the interior is beautifully crafted, with top-notch materials and tight panel fitment. The standard MB Tex vinyl upholstery is convincingly leather-like -- uninitiated passengers will likely mistake it for the real thing. Headroom is ample all around, but rear legroom is tight. Getting in and out can be a squeeze, too.

Some cabin controls are overly complicated, and the climate controls are mounted a little low, but the overall combination of physical dash buttons, steering wheel controls and the optional multifunction COMAND knob are reasonably effective at corralling the GLK's various functions. Maximum cargo capacity is 54.7 cubic feet, which is less than most luxury competitors.

I Love My Car But...
GLK350 4dr SUV (3.5L 6cyl 7A)
I Love my Car. We are around 110000 miles now. Over all I love everything about my car except I always need to fix it. My car lock needed to be fixed, that was $1000 Seals around the doors are cracking. Chrome trim around cup holders are peeling. Buttons are wearing off. Middle console it scratching. Basically anything plastic will and has fallen apart. I know it sounds all horrible but my car in almost mint condition and all these things are things only I would notice since I detail my car daily but the fact is I have noticed. I've spent $3000 in maintenance this year. Over all I love my car it handles well, I feel special driving it. But if you don't have the extra cash I'd say pass.
Good little car
Good car. Very reliable. Bought with 8k mikes in 2011. Now have 90k. Never had anything other than oil changes done to it. I do NOT recommend the 20 inch wheels. They go through tires fast. Needs more storage. Don't like the angle of the backseat. Also don't like the curve of the backseat next to the door. Makes it hard for car seats to properly fit. It gets good mpg in flatter terrain. But in the small mountains of Arkansas, I'm getting about 9mpg. It's a great compact SUV, very capable. Having to get rid of it due to my child needing more legroom. Would buy again if they could upgrade storage and me the backseat larger.
Fell Apart
Jerry Proctor,04/21/2016
GLK350 4MATIC 4dr SUV AWD (3.5L 6cyl 7A)
Still a nice looking vehicle. Has the chrome 20" wheels updated headlights and door sill lights. But... @60,000 Miles, Repairs needed Differential leaks $4600.00 New Motor Mounts $2600.00 Trans axle Leak $1500.00 Seats are not real leather and have fallen apart. Uses a lot of gas and the tires are lasting about 30k.
2010 with 64k has been a Great Car
GLK350 4dr SUV (3.5L 6cyl 7A)
We bought a 2010 with 28k and 2-years on it. Everything has been great. The only issue we've had existed when we bought it -- a worn "arm" in the front-end steering. The cost was relatively low to repair -- I think $150. No other repairs or problems to report. I have used MB to performed the 50k and 60k service, which was pricey and probably not worth the cost, but work keeps me busy and don't have time or the interest to mess with it. My wife loves the car and I have to admit that I really enjoy zipping around in it, too. It has great acceleration and turns on a dime. Getting in/out of our side-enterence garage is a piece of cake!! We'll probably buy a low-miles 2015 in another few years.

More About This Model

The three-pointed Mercedes star is usually enough for people to buy whatever old thing it's glued to, regardless of whether it truly lives up to the brand's historic pedigree. Look no further than the dumpy C-Class hatchback of a few years ago or Europe's tiny A-Class that resembles a minivan sent through a trash compactor. To be honest, before we drove it, we thought the 2010 Mercedes GLK350 4Matic would be one of these cash-grab products preying on customer vanity and the popularity of compact SUVs. We were wrong.

True, the GLK will still appeal to brand snobs in search of a small luxury sport-utility, but it at least does it while being a meticulously engineered piece of 100 percent Mercedes-Benz excellence -- if it were any more German, it'd be named Gretel. The GLK may be the second-cheapest Benz you can buy in the United States, but it certainly doesn't seem that way. Closing the doors is like sealing yourself in Terry Benedict's Bellagio vault -- impenetrable to everything but George Clooney and 10 pals. Railroad tracks and deep potholes are casually brushed off without a millimeter of body flex. It feels as if you could roll over a grenade and suffer nothing but a muted thump. On second thought, forget Gretel; try Panzer.

The current Mercedes C-Class feels the same way, and it's no surprise that the GLK is based on the compact sport sedan. The steering and ride quality feel similar to the C, while both Benzes share the same 268-horsepower 3.5-liter V6 (the only engine available in the GLK). However, the platform's compact SUV version is 4 inches shorter in length, plus it receives the obvious ride and body height pump up. While the result may not be the sportiest compact SUV around, like the C350, the GLK350 represents an ideal balance between ride and handling that should please most luxury buyers.

We were prepared to dislike the 2010 Mercedes-Benz GLK350, but we handed over its keys duly impressed. While others provide more space and/or more equipment for the same amount of money (or less), none offer those unmatchable Mercedes traits of painstaking over-engineering and top-notch interior craftsmanship that is certainly worth some, if not all, the price premium. Not all Benzes have upheld these traditions, but the GLK has most certainly earned its three-pointed star.

Should I lease or buy a 2010 Mercedes-Benz GLK-Class?

Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
