The 2013 Mercedes-Benz GLK350 often gets described as the wagon version of the C350 sport sedan, which isn’t far off given they share the same platform and a potent 3.5-liter V-6 engine. You might look at the photos and think, “Wait, that’s an SUV, right?”
Indeed, the 2013 Mercedes-Benz GLK350 is categorized as a compact luxury SUV, but its dimensions might surprise you. Despite its SUV styling, the GLK350 is actually quite similar in size to the C-Class sedan. Measuring 178.3 inches in overall length with a 108.5-inch wheelbase, its footprint is comparable to its sedan sibling. While it is about 5 inches wider and 10 inches taller than the C-Class, and weighs a bit more (at least 463 pounds, with our 4Matic all-wheel-drive test model likely heavier), the GLK350 cleverly balances SUV practicality with a manageable size.
This means the 2013 GLK350 can still navigate city streets and fit into parking spaces like a sedan, but it provides significantly more cargo capacity – ranging from 23.3 cubic feet to 54.7 cubic feet with the rear seats folded. Passengers also benefit from increased headroom and a more commanding, elevated driving position, a hallmark of the SUV experience.

Potent Performance and Efficient Engine
While the increased size and weight of the 2013 Mercedes-Benz GLK350 might slightly impact performance compared to the C350 sedan, it still delivers satisfying power. Under the hood lies the same 3.5-liter V-6 engine found in the C350. This naturally aspirated engine utilizes direct-injection technology to optimize both power output and fuel efficiency. It produces a healthy 302 horsepower and 273 pound-feet of torque, providing ample acceleration and confident highway cruising.
Power is delivered to the wheels through a smooth-shifting seven-speed automatic transmission. While a manual shift mode is absent – the steering column shifter is a traditional PRND setup and paddle shifters are not included – the transmission offers Sport and Economy modes. Sport mode holds gears longer, allowing the engine to rev higher and access more of its horsepower, while Economy mode prioritizes fuel efficiency by shifting to higher gears quickly and keeping engine revs low.
The 2013 Mercedes-Benz GLK350 also incorporates an Eco Start-Stop system to further enhance fuel economy. This system automatically shuts off the engine when the vehicle comes to a complete stop, such as at traffic lights, and restarts it seamlessly when you lift your foot from the brake pedal. In practice, the system is generally smooth and unobtrusive, with a quick restart that allows for prompt acceleration. However, in heavy stop-and-go traffic, some drivers might find the repeated engine restarts slightly noticeable, though a button on the dashboard allows for easy deactivation of the system.
Fuel economy for the 4Matic all-wheel-drive model is EPA-rated at 19 mpg city, 24 mpg highway, and 21 mpg combined. Rear-wheel-drive models achieve slightly better highway fuel economy. While these figures are respectable for a luxury SUV with a V6 engine, they aren’t class-leading. It’s also worth noting that Mercedes-Benz recommends premium gasoline for the GLK350, which can slightly increase running costs.

Comfortable Handling and Refined Ride
The 2013 Mercedes-Benz GLK350 delivers a driving experience that is both comfortable and composed, reflecting its C-Class platform origins. Around town, it handles with agility and responsiveness expected from a car-based crossover. The suspension is tuned to provide a smooth ride, effectively absorbing bumps and road imperfections, while still maintaining a connection to the road. The optional 20-inch wheels on our test vehicle contribute to a slightly firmer ride, but even with these larger wheels, the ride remains comfortable for daily driving.
The suspension strikes a good balance, offering responsive handling when maneuvering through city traffic and minimizing body roll during cornering. While not designed for aggressive off-roading, the GLK350’s firm suspension provides confidence and control in everyday driving situations.
The elevated seating position of the GLK350 provides excellent visibility, aiding in navigating tight spots and parking. The large windows and airy cabin contribute to good all-around visibility, although judging the vehicle’s corners during parking maneuvers might require some adjustment.
On the highway, the 2013 GLK350 truly shines as a comfortable cruiser. The suspension smooths out high-frequency road imperfections, providing a relaxed and enjoyable ride for long journeys. While larger road undulations can still be felt in the cabin, the overall highway ride quality is refined and well-suited for long-distance driving.
The 2013 Mercedes-Benz GLK350, equipped with optional 20-inch wheels and a firm suspension, prioritizes on-road driving dynamics over off-road capabilities.

Cabin Comfort and Technology Features
The interior of the 2013 Mercedes-Benz GLK350 offers a blend of luxury and functionality. Standard features include a 5.8-inch color display screen and the COMAND infotainment system, controlled via a central knob on the console. The base audio system includes a CD player, AM/FM radio, and Bluetooth hands-free calling.
However, to access modern audio and connectivity features, buyers will likely want to opt for the Premium package. This package adds iPod/iPhone integration, USB input for MP3 playback, Bluetooth audio streaming, and SiriusXM satellite radio. It also includes desirable features like a panoramic sunroof and a power liftgate.
Navigation is available as part of the Multimedia package, which also includes a hard-drive-based navigation system, enhanced voice control, and a rearview camera. While the navigation system is functional, some may find the interface and graphics dated compared to modern smartphone-based navigation apps.
Additional optional packages and stand-alone options allow for further customization. These include a leather package, Sport Appearance package with 20-inch wheels and roof rails, keyless entry and start, and a Harman Kardon Logic7 premium audio system. Driver assistance features are also available, including lane tracking (blind-spot monitoring and lane-keeping assist) and a more comprehensive Driver Assistance package with active lane keeping and adaptive cruise control.
The array of available options allows buyers to personalize their GLK350, but the a-la-carte pricing structure can quickly escalate the vehicle’s price. Features that are often standard on more mainstream vehicles, such as heated seats, are optional extras on the GLK350.

Connectivity and Mercedes-Benz Apps
Mercedes-Benz offered several levels of connectivity for the 2013 GLK350. The Mbrace package provided basic connected services like automatic collision detection, roadside assistance, and stolen vehicle recovery, along with a smartphone app for remote vehicle access. Mbrace Plus added concierge services, destination download, traffic and weather updates, and speed alerts.
However, the Mercedes-Benz Apps package, intended to bring smartphone-like functionality to the COMAND system, was less impressive. This package included a web browser, Google Local Search, Yelp, Facebook, news, and stocks apps. In practice, the system was slow and cumbersome to use, making it less practical than simply using a smartphone for these functions. While the idea of in-car apps was forward-thinking for its time, the execution in the 2013 GLK350 fell short of providing a seamless and user-friendly experience.
Conclusion: A Capable and Comfortable Compact Luxury SUV
The 2013 Mercedes-Benz GLK350 offers a compelling blend of luxury, practicality, and performance in a compact SUV package. Starting at a base price of around $39,090 for the 4Matic all-wheel-drive model, the GLK350 provides a refined driving experience, a comfortable interior, and a range of available technology and features. However, as tested prices can climb quickly with options, reaching upwards of $50,000 or even $60,000, it’s important for buyers to carefully consider their needs and budget when selecting options.
Overall, the 2013 Mercedes-Benz GLK350 remains a solid choice for those seeking a compact luxury SUV. It provides a comfortable and capable driving experience, a well-appointed cabin, and the prestige of the Mercedes-Benz brand. While the technology may feel somewhat dated compared to newer models, and the options can be pricey, the GLK350 still holds its own as a desirable and practical luxury SUV in the used car market.
The 2013 Mercedes-Benz GLK350, despite its relatively small size, delivers a luxurious and comfortable experience.
