The Mercedes-Benz GLA 220d, specifically the facelift model produced from January 2017 to May 2018 (designated X156), represented a compelling entry point into the compact luxury SUV segment. Positioned as a mid-range offering within the GLA lineup, it bridged the gap between the lower-powered GLA 200d and the more performance-oriented GLA 250. This variant combined a 2.1-liter turbocharged diesel engine with the 7G-DCT dual-clutch transmission, offering a balance of fuel efficiency, respectable performance, and Mercedes-Benz refinement. The GLA, as a whole, was Mercedes-Benz’s attempt to capture a younger demographic with a more accessible and stylish SUV, leveraging the robust mechanicals of the A-Class (W176) and B-Class (W246) platforms.

INTRODUCTION
The Mercedes-Benz GLA 220d (X156 facelift) debuted in January 2017 as part of a mid-cycle refresh for the first-generation GLA. Built on the MFA (Modular Front-wheel drive Architecture) platform – shared with the A-Class and B-Class – the GLA aimed to bring the Mercedes-Benz experience to a more compact and accessible package. The 220d variant, powered by the OM651.930 engine and paired with the 7G-DCT transmission, was positioned as a sweet spot in the range, offering a good balance of performance, economy, and refinement. Production of this specific configuration continued until May 2018, when the X156 was superseded by the second-generation GLA (H247).
Powertrain & Engine Architecture
At the heart of the GLA 220d lies the OM651.930 2.1-liter inline-four cylinder diesel engine. This engine, a mainstay in many Mercedes-Benz models, is known for its durability and efficiency. It features a common-rail direct injection system, delivering fuel at extremely high pressure for optimized combustion. A turbocharger with an intercooler further enhances power output. The engine produces 177 horsepower at 3600-3800 rpm and 350 Nm (258 lb-ft) of torque between 1400 and 3400 rpm. The 7G-DCT (7-speed Dual Clutch Transmission) is a crucial component of this powertrain. This transmission offers quick and smooth gear changes, contributing to both performance and fuel economy. It operates with two separate clutches, one for odd-numbered gears and one for even-numbered gears, allowing for pre-selection of the next gear for seamless shifts. The transmission also includes a manual shift mode for driver control.
Driving Characteristics
The GLA 220d 7G-DCT delivers a comfortable and refined driving experience. While not overtly sporty, the engine provides sufficient power for everyday driving and highway cruising. The 7.7-second 0-100 km/h (0-62 mph) acceleration time is respectable for a compact diesel SUV. The 7G-DCT transmission contributes to smooth acceleration and responsive gear changes. Compared to the lower-powered GLA 200d, the 220d offers noticeably more punch, particularly when overtaking. However, it doesn’t match the performance of the GLA 250, which boasts a more powerful gasoline engine. The gear ratios in the 7G-DCT are well-chosen for both fuel efficiency and drivability, providing a good balance between low-end torque and high-speed cruising ability. The front-wheel-drive configuration provides adequate traction in most conditions, although it can exhibit some torque steer under hard acceleration.
Equipment & Trim Levels
The GLA 220d typically came well-equipped, reflecting its position as a mid-range model. Standard features often included automatic climate control, a multimedia system with a central display screen, Bluetooth connectivity, and a suite of safety features such as ABS, ESP, and multiple airbags. Interior upholstery was typically Artico leatherette (synthetic leather), with options for genuine leather upgrades. Common optional extras included a panoramic sunroof, navigation system, upgraded sound system, parking assist, and various driver assistance packages. Trim levels varied slightly depending on the market, but generally offered progressive enhancements in terms of interior materials, exterior styling, and technology features.
Chassis & Braking
The GLA 220d utilizes a McPherson strut front suspension and a multi-link rear suspension. This setup provides a good balance of ride comfort and handling. The suspension is tuned to prioritize comfort, but still offers reasonable body control in corners. Braking duties are handled by ventilated discs at the front and solid discs at the rear. ABS (Anti-lock Braking System) and ESP (Electronic Stability Program) are standard features, enhancing safety and stability. The steering is electrically assisted, providing a light and precise feel. The GLA 220d’s weight of approximately 1465 kg (3229.77 lbs) is relatively low for its class, contributing to its agility and fuel efficiency.
Market Reception & Comparison
The GLA 220d was generally well-received by automotive critics. It was praised for its fuel efficiency, comfortable ride, and refined interior. The 7G-DCT transmission was also a highlight, offering smooth and responsive gear changes. Compared to the GLA 200d, the 220d offered a significant performance upgrade without a substantial increase in fuel consumption. Against the GLA 250, the 220d offered better fuel economy and lower running costs, but at the expense of outright performance. The GLA 220d competed with other compact luxury SUVs such as the Audi Q3, BMW X1, and Volvo XC40.
Legacy
The Mercedes-Benz GLA 220d (X156 facelift) has proven to be a reliable and durable vehicle. The OM651.930 engine is known for its longevity, and the 7G-DCT transmission, while complex, has generally proven to be robust when properly maintained. In the used car market, the GLA 220d remains a popular choice, offering a good balance of luxury, practicality, and fuel efficiency. However, potential buyers should be aware of the importance of regular maintenance, particularly regarding the diesel particulate filter (DPF) and the dual-clutch transmission. Overall, the GLA 220d represents a well-rounded and capable compact SUV that continues to offer a compelling ownership experience.
