When the time came to replace my trusty old 2003 Mitsubishi Outlander, I knew I wanted something similar but newer and perhaps a touch more refined. This led me to the compact SUV/crossover category, a segment brimming with options. After extensive research across various models and years, I narrowed my choices down to two, one of which I’ve reviewed previously. The other, and ultimately the vehicle I chose, was a 2014 Mercedes-Benz GLK 250.

It’s almost a given that the GLK 250 exudes quality in every aspect. The interior is a genuinely comfortable and well-crafted space, with everything thoughtfully arranged. My particular model boasts the premium touches you’d expect from a Mercedes-Benz. While some of these features are becoming increasingly common in newer vehicles, they felt refreshingly modern compared to my previous car’s bare-bones setup.
Visibility in the GLK 250 is commendable, especially for an SUV of this type. It’s certainly no worse than my old Outlander. While it includes a rearview camera, maneuvering in reverse is straightforward even without relying on it, avoiding the blind-spot guesswork that plagues some vehicles.
Surprisingly, the GLK 250’s dimensions are almost identical to my Outlander, despite appearing larger. It shares the same length, nearly the same height, and is only an inch wider, meaning it fits perfectly in my garage – a significant convenience.
In terms of technology, the GLK 250 features a user-friendly media system with conveniently placed physical buttons for mode switching, a feature I particularly appreciate and one that’s surprisingly absent in some modern cars. The integrated navigation system is functional and gets the job done, though it’s not particularly advanced.
However, the real highlight and the primary reason I chose the GLK 250 is its engine. The GLK class comes in two main variants: the 350 and the 250. The 350 is equipped with a 3.5-liter V6 gasoline engine, while the 250 boasts a diesel engine – specifically, a 2.1-liter twin-turbo inline-4. This diesel powerplant delivers 200 horsepower and an impressive 369 lb-ft of torque.
This remarkable torque figure is what truly sold me on the GLK 250.
I test drove both the 350 and the 250 before making my decision. While the 350’s engine offered ample power, I found its delivery somewhat challenging to manage. The throttle response in the 350 felt inconsistent, initially seeming unresponsive before suddenly unleashing a surge of power that was difficult to modulate, especially at lower speeds.
In contrast, the 250’s diesel engine delivers power smoothly and effortlessly. Crucially, most of this power is accessible at lower RPMs, a characteristic of diesel engines and similar to the power band of my old Outlander.
This abundance of low-end torque also enhances towing capability. The GLK 250 boasts a maximum trailer weight of 3,500 lbs, significantly exceeding the towing capacity of my Outlander.
Despite its relatively modest horsepower for a vehicle weighing around 4,246 lbs, the GLK 250 accelerates with surprising eagerness. There’s a slight initial hesitation off the line, but the smaller of the two turbos spools up rapidly, providing consistent and even power delivery thereafter. It might not be the fastest vehicle in its class, but it certainly feels quicker than the numbers suggest, offering a steady and relentless acceleration.
Even at highway speeds, power is readily available. A simple press of the accelerator results in immediate forward motion, and you’ll quickly find yourself exceeding your intended speed.
This power is managed by a 7-speed automatic transmission that I can only describe as “buttery smooth.” In typical driving conditions, gear changes are almost imperceptible. The transmission shifts quickly and responsively, readily moving up and down the gears as needed. A clever feature is its ability to downshift automatically to assist with speed control on downhill slopes – a function I’ve never encountered in any other automatic gearbox.
Of course, the GLK 250 also features Mercedes-Benz’s 4MATIC all-wheel-drive system. This ensures that all that diesel power is effectively translated to the road, even in slippery conditions.
The engine incorporates variable valve control, but the power delivery remains consistently smooth and controlled, without any sudden surges. Once the turbo is engaged, the power delivery is remarkably linear.
Considering its substantial AWD system and somewhat boxy aerodynamic profile, the GLK 250 achieves impressive fuel economy figures of 24 mpg city and 33 mpg highway. In real-world driving, it often performs even better. Combined with a 17.4-gallon fuel tank, the GLK 250 offers an exceptional cruising range, perfect for long journeys.
Adding to its long-distance appeal, the GLK 250 is exceptionally comfortable for extended periods behind the wheel. The suspension effectively absorbs bumps and road imperfections without feeling overly soft or disconnected, as can be the case with overly compliant suspension systems. It strikes a balance, providing sufficient softness for rough roads while remaining firm enough to inspire confidence when tackling corners in this substantial SUV.
Regarding the diesel engine itself, having driven several diesel vehicles previously, including an Audi A4 wagon and a Fiat 500L, there’s a distinct driving characteristic to adapt to. Diesel engines typically deliver their power low in the rev range, negating the need for high-revving performance. The addition of turbos further alters the experience if you’re primarily accustomed to naturally aspirated engines. However, the undeniable benefit is abundant torque. While these diesel vehicles might not be outright speed demons, they are undeniably quick and responsive in everyday driving situations.
In an SUV application, I believe a diesel engine is an ideal match – providing the necessary power to move a heavier vehicle while maintaining fuel efficiency. It’s a shame they aren’t more prevalent, particularly in the US market.
The GLK 250 does have a few minor drawbacks, none of which were deal-breakers for me, but they are worth considering and might be more significant for others.
The primary drawback is rear seat legroom, which is somewhat limited. As mentioned earlier, the GLK 250 is the same length as my Outlander, but the GLK’s larger engine bay necessitates compromises elsewhere. In this case, the rear seats bear the brunt, with reduced legroom. The front seats and cargo area remain virtually identical in size to my old Outlander. While not excessively cramped, rear legroom isn’t generous, especially if front occupants require their seats far back. For me, rarely having rear passengers, this wasn’t a major issue, but it could be a significant downside for those who regularly transport more than two people.
Adding to the rear passenger experience, the rear wheel arches intrude into the rear door openings more than ideal, making ingress and egress slightly awkward at times. It’s not overly challenging, but noticeable. Passengers with mobility limitations might find accessing the rear seats of the GLK less than ideal.
Another minor quirk of the GLK is that later model years relocated the transmission lever to the steering wheel column. While not resembling the cumbersome column shifters of older vehicles, it requires an adjustment period. More than once, I instinctively reached for a center console shifter before remembering it’s now a small stalk on the steering column.
Overall, I believe the Mercedes-Benz GLK 250 is a truly excellent SUV. The diesel engine injects fun into the driving experience, and despite its comfort-oriented nature, it retains a strong sense of practicality. If you’re seeking a smaller SUV that blends style, comfort, and a torquey diesel engine, the GLK 250 is definitely worth a serious look.
