The Mercedes-Benz GLA 220d 4MATIC, produced from January 2017 to May 2018, represents a mid-cycle refresh of the X156 GLA generation. Positioned as a premium compact SUV, the 220d variant offered a balance between fuel efficiency, performance, and all-wheel-drive capability. This model aimed to appeal to buyers seeking a versatile vehicle for both urban commuting and occasional longer journeys, within the burgeoning compact luxury crossover segment. It sat in the middle of the GLA range, offering more performance than the 180d and 200d models, but remaining more accessible than the higher-performance AMG variants.
Powertrain & Engine Architecture
At the heart of the GLA 220d 4MATIC lies the OM 651.930, a 2.143-liter inline-four cylinder diesel engine. This engine is a common rail direct injection diesel, utilizing piezo injectors for precise fuel delivery. The turbocharger, coupled with an intercooler, boosts power output to 177 horsepower at 3600-3800 rpm and 350 Nm (258 lb-ft) of torque between 1400-3400 rpm. The engine features a double overhead camshaft (DOHC) valvetrain with four valves per cylinder, optimizing breathing and efficiency. The 7G-DCT (7-speed dual-clutch transmission) was standard, offering quick and smooth gear changes. This transmission is known for its efficiency and responsiveness, contributing to the vehicle’s overall fuel economy. The dual-clutch design allows for pre-selection of the next gear, minimizing interruption in power delivery.
Driving Characteristics
The GLA 220d 4MATIC delivers a comfortable and refined driving experience. While not a sports car, the 177 hp engine provides adequate power for everyday driving and highway cruising. The 7G-DCT transmission contributes to brisk acceleration, with a 0-60 mph time of around 7.3 seconds. The torque-rich diesel engine provides strong pulling power from low revs, making it easy to navigate city traffic and overtake slower vehicles. The 4MATIC all-wheel-drive system enhances traction and stability, particularly in adverse weather conditions. Compared to the lower-powered GLA 200d, the 220d offers a noticeable performance improvement. However, it doesn’t match the responsiveness of the higher-output gasoline engines or the AMG variants. The gear ratios are tuned for a balance between fuel efficiency and performance, with taller gears for highway cruising and shorter gears for quicker acceleration.
Equipment & Trim Levels
The GLA 220d 4MATIC typically came well-equipped, reflecting its premium positioning. Standard features 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, with options for genuine leather upgrades. Common optional extras included a panoramic sunroof, navigation system, upgraded sound system, and driver assistance packages featuring features like lane keeping assist and blind spot monitoring. Trim levels varied by market, but generally offered increasing levels of luxury and technology. The Sport trim added styling enhancements, while the AMG Line package included more aggressive bodywork and sport-tuned suspension.
Chassis & Braking
The GLA 220d 4MATIC utilizes a McPherson strut front suspension and a multi-link rear suspension. This setup provides a good balance between ride comfort and handling. Stabilizer bars are fitted to both axles to reduce body roll during cornering. The braking system consists of ventilated discs at the front and solid discs at the rear. ABS (Anti-lock Braking System) and ESP (Electronic Stability Program) are standard, enhancing safety and control. The 4MATIC all-wheel-drive system employs a multi-plate clutch to distribute torque between the front and rear axles as needed, optimizing traction in various driving conditions.
Market Reception & Comparison
The GLA 220d 4MATIC was generally well-received by automotive critics. It was praised for its fuel efficiency, comfortable ride, and practical interior. The diesel engine was noted for its refinement and strong torque output. However, some reviewers found the styling to be somewhat conservative and the handling less engaging than some of its rivals. Compared to the gasoline-powered GLA 250, the 220d offered significantly better fuel economy, but slightly slower acceleration. The 220d also provided a more affordable entry point into the GLA range compared to the higher-performance AMG models. Reliability reports suggest that the OM 651 engine is generally robust, but regular maintenance is crucial to prevent issues with the diesel particulate filter (DPF) and fuel injection system.
Legacy
The GLA 220d 4MATIC remains a popular choice in the used car market, particularly for buyers seeking a fuel-efficient and practical compact SUV. The OM 651 diesel engine has proven to be relatively durable, although preventative maintenance, including regular oil changes and DPF regeneration, is essential. The 7G-DCT transmission is also generally reliable, but requires proper servicing to ensure smooth operation. The X156 GLA, including the 220d variant, helped establish Mercedes-Benz as a major player in the compact SUV segment, paving the way for the current-generation GLA (H247). Its blend of practicality, efficiency, and premium features continues to appeal to a wide range of buyers.
