When the time came to replace my aging 2003 Mitsubishi Outlander, I knew I wanted something similar but more modern and refined. My search led me to the popular “compact SUV/crossover” category, which boasts a wide array of vehicles. After extensive research across various model years, I narrowed my choices down to two, one of which I had previously reviewed. The ultimate choice, and the focus of this review, became the 2014 Mercedes-Benz GLK 250.
The Mercedes-Benz GLK 250 immediately impresses with its luxurious feel and meticulous construction. The interior is exceptionally comfortable and well-organized, reflecting the high standards expected from Mercedes-Benz. Even though many of its features are now commonplace in newer vehicles, coming from an older car, they felt refreshingly modern and sophisticated.
Visibility in the GLK 250 is commendable, particularly for an SUV. It feels comparable to my previous Outlander, offering a clear view of the surroundings. While a rearview camera is included, reversing is manageable even without relying on it, minimizing blind spots and enhancing safety.
In terms of size, the GLK 250 is surprisingly similar to my old Outlander. Despite appearing larger, it shares nearly identical length and height dimensions, with only a minor one-inch difference in width. This similarity was a practical advantage, as it fit perfectly into my garage space without any adjustments.
Technologically, the GLK 250 features a user-friendly media system. The inclusion of easily accessible physical buttons for switching modes is a notable positive, a feature not universally present in all modern cars. The integrated navigation system is functional and reliable, although not exceptionally advanced.
However, the defining feature that led me to choose the GLK 250 is its engine. The GLK class offers two engine variants: the 350 with a 3.5-liter V6 gasoline engine, and the 250, equipped with a diesel engine. Specifically, the GLK 250 houses a 2.1-liter twin-turbo inline-4 diesel, producing 200 horsepower and a substantial 369 lb-ft of torque.

This diesel engine is the heart of the GLK 250’s appeal. Having test-driven both the 250 and 350 models, I found the power delivery of the GLK 250’s diesel to be more refined and manageable. The GLK 350’s gasoline engine, while powerful, exhibited a somewhat sensitive throttle response, making power modulation tricky, especially at lower speeds.
In contrast, the GLK 250 diesel delivers power smoothly and effortlessly. Characteristic of diesel engines, a significant portion of its torque is available at lower RPMs, mirroring the power band of my previous Outlander. This low-end torque is beneficial for everyday driving and contributes to a more relaxed driving experience.
The robust torque of the diesel also enhances the GLK 250’s towing capability. With a maximum trailer weight of 3,500 lbs, it surpasses the towing capacity of my old Outlander, adding to its utility.
Despite having a modest 200 horsepower for its weight class (approximately 4,246 lbs), the Mercedes Suv Glk 250 demonstrates impressive acceleration. There is a slight initial lag off the line, typical of turbocharged engines, but the smaller turbocharger spools up quickly, providing consistent and even power delivery thereafter. While not a sports car, the GLK 250 accelerates steadily and confidently, feeling perhaps even quicker than its specifications might suggest.
On highways, the GLK 250 maintains ample power reserves. A simple press of the accelerator results in immediate and smooth acceleration, effortlessly reaching and maintaining higher speeds.
Power is transmitted through a 7-speed automatic transmission that is remarkably smooth. Gear changes are almost imperceptible during normal driving. The transmission shifts swiftly and responsively, readily adapting to driver input and road conditions. A notable feature is its ability to downshift automatically when descending hills, aiding in speed control – a sophisticated function rarely found in other automatic gearboxes.
Equipped with Mercedes-Benz’s 4MATIC all-wheel-drive system, the GLK 250 ensures excellent traction in various driving conditions, including slippery surfaces. This AWD system inspires confidence and enhances safety, especially in inclement weather.
The engine incorporates variable valve control, contributing to its efficiency and smooth power delivery. The power delivery is linear and predictable once the turbocharger is engaged, without any abrupt power surges.
Remarkably, the GLK 250 achieves commendable fuel economy figures for an AWD SUV with a substantial profile, offering 24 mpg in the city and 33 mpg on the highway. Real-world driving often yields even better results. Combined with a 17.4-gallon fuel tank, the GLK 250 boasts an exceptional cruising range, making it ideal for long journeys.
The Mercedes SUV GLK 250 excels in long-distance comfort. The suspension effectively absorbs road imperfections without feeling overly soft or detached, striking a balance between comfort and handling. It provides a comfortable ride on rough surfaces while maintaining sufficient firmness for confident cornering, even for a heavier SUV.
Having driven several diesel vehicles, including the Audi A4 wagon and Fiat 500L, I appreciate the unique characteristics of diesel engines. Their power delivery is concentrated at lower RPMs, requiring less high-revving compared to gasoline engines. The addition of turbochargers further enhances torque, resulting in a responsive and powerful driving experience, especially suitable for SUVs requiring low-end grunt. It’s unfortunate that diesel SUVs are not more prevalent, particularly in the US, as they offer an excellent blend of power and efficiency for this vehicle type.
The GLK 250 does have minor drawbacks. Rear seat legroom is somewhat limited. While the GLK 250 shares overall length with my Outlander, the larger engine bay slightly compromises rear passenger space. Front seat and cargo space remain comparable to the Outlander. While not severely cramped, rear legroom is not generous, particularly when front seats are positioned far back. For those frequently carrying rear passengers, this could be a significant consideration.
Additionally, the rear wheel arches intrude slightly into the rear door openings, making ingress and egress a bit less convenient, especially for rear passengers. While not overly problematic, it is noticeable, and passengers with mobility issues might find rear access challenging.
Another minor peculiarity is the relocation of the transmission lever to the steering column in later GLK models. Although not a traditional column shifter, it takes time to adapt to its position. Initially, I occasionally reached for a nonexistent center console shifter before remembering its new location on the steering column stalk.
Overall, the Mercedes SUV GLK 250 is an outstanding compact luxury SUV. Its diesel engine delivers a thrilling driving experience, blending performance with fuel efficiency. Comfortable and versatile, it offers a compelling combination of luxury and utility. For those seeking a stylish and comfortable small-to-medium SUV, the GLK 250 is definitely worth considering.
