The Mercedes-Benz X-Class X 250d 4MATIC Automatic, produced from November 2017 to May 2020, represented a unique entry into the mid-size pickup truck segment for the German automaker. This variant, powered by a 2.3-liter turbocharged diesel engine producing 190 horsepower, occupied a central position within the X-Class lineup, offering a balance between performance, fuel efficiency, and capability. It was positioned above the base X 220d model and below the more powerful X 350d, targeting buyers seeking a versatile vehicle for both work and leisure. The X-Class as a whole was based on the Nissan Navara D23 platform, representing a collaboration between Mercedes-Benz and the Renault-Nissan Alliance.
Powertrain & Engine Architecture
The heart of the X 250d is the OM 699.3, a 2.3-liter inline-four cylinder diesel engine. This engine is part of Mercedes-Benz’s modular engine family, known for its robust construction and efficiency. The OM 699.3 utilizes a commonrail direct fuel injection system, delivering fuel at extremely high pressure for optimized combustion. This system, coupled with a variable geometry turbocharger and intercooler, allows for a broad torque curve and responsive power delivery. The engine boasts a compression ratio of 15.4:1 and features four valves per cylinder, contributing to its efficiency and power output. Bore and stroke dimensions are 85mm x 101.3mm respectively, resulting in a displacement of 2298 cm³ (140.23 cubic inches).
The X 250d was exclusively offered with a 7-speed automatic transmission (7G-TRONIC PLUS). This transmission is known for its smooth shifting characteristics and ability to adapt to various driving conditions. The automatic transmission features selectable drive modes, including Comfort, Sport, Manual, and Off-Road, allowing the driver to tailor the vehicle’s response to the terrain and driving style. The transmission’s gear ratios are optimized for both on-road cruising and off-road crawling, providing a balance of fuel efficiency and capability.
Engine Specifications
Key engine specifications include a maximum power output of 190 hp at 3750 rpm and a peak torque of 450 Nm (331.9 lb-ft) available between 1500 and 2500 rpm. This torque output provides ample pulling power for towing and hauling, making the X 250d a capable workhorse. The engine also incorporates a diesel particulate filter (DPF) to meet stringent Euro 6 emission standards.
Driving Characteristics
The X 250d 4MATIC Automatic delivers a refined driving experience for a pickup truck. While not as overtly powerful as the X 350d, the 190 hp engine provides sufficient power for everyday driving and most typical hauling tasks. Acceleration from 0 to 100 km/h (0-62 mph) takes approximately 11.8 seconds, and 0-60 mph is achieved in around 11.2 seconds. The 7-speed automatic transmission contributes to smooth and seamless gear changes, enhancing comfort during both city driving and highway cruising. The 4MATIC all-wheel-drive system provides excellent traction in various conditions, making the X 250d capable off-road. The longitudinal engine layout and rear-wheel-drive bias contribute to a balanced and predictable handling characteristic.
Compared to the base X 220d, the X 250d offers a noticeable improvement in performance, particularly when carrying a load or towing a trailer. The higher horsepower and torque figures translate to quicker acceleration and more confident overtaking. However, it doesn’t match the outright performance of the X 350d, which boasts a significantly more powerful V6 engine.
Equipment & Trim Levels
The X 250d 4MATIC Automatic was available in several trim levels, including Pure, Progressive, and Power. The base Pure trim offered a functional and utilitarian interior, with durable materials and essential features. The Progressive trim added more comfort and convenience features, such as upgraded upholstery, infotainment system, and exterior styling elements. The top-of-the-line Power trim included premium leather upholstery, advanced driver-assistance systems, and a more luxurious overall experience.
Standard equipment on most X 250d models included air conditioning, power windows and locks, a basic audio system, and a multi-function steering wheel. Optional extras included a larger touchscreen infotainment system with navigation, heated seats, a sunroof, and various off-road packages. Interior upholstery options ranged from durable cloth to high-quality leather, depending on the trim level.
Chassis & Braking
The X-Class chassis is based on the Nissan Navara platform, featuring a robust ladder frame construction. The suspension system consists of independent double wishbones at the front and a multi-link rear suspension. This setup provides a comfortable ride quality and good handling characteristics, even when carrying a load. The X 250d is equipped with ventilated disc brakes on all four wheels, providing ample stopping power. Anti-lock braking system (ABS) is standard, enhancing safety during emergency braking situations. The electric power steering system offers precise and responsive steering feel. Ride height (ground clearance) is 202mm (7.95 inches), providing good off-road capability.
Market Reception & Comparison
The Mercedes-Benz X-Class received mixed reviews upon its launch. Critics praised its refined interior, comfortable ride, and capable all-wheel-drive system. However, some criticized its relatively high price compared to competitors like the Ford Ranger and Toyota Hilux, as well as its limited payload capacity. The X 250d was generally considered a good compromise between performance and fuel economy, offering a more refined driving experience than the base X 220d without the higher cost of the X 350d. Fuel economy figures are rated at 7.9 l/100 km (29.8 US mpg) combined, with 9.6 l/100 km (24.5 US mpg) in urban conditions and 6.9 l/100 km (34.1 US mpg) on the extra-urban cycle. CO2 emissions are rated at 207 g/km.
