INTRODUCTION
The Mercedes-Benz GLA 220d 4MATIC (X156 facelift) arrived as part of a mid-cycle refresh for the first-generation GLA, launched in 2014. Built on the MFA (Modular Front-drive Architecture) platform – also known as the 1HX0/A3 platform shared with other compact Mercedes-Benz and Renault models – the GLA aimed to bring the brand’s luxury and technology to a more accessible, crossover-shaped package. The 220d variant, powered by a 2.1-liter turbocharged diesel engine, was a key offering in many European markets, where diesel fuel was prevalent and fuel economy was a high priority. The facelift brought styling updates, improved interior materials, and enhanced technology features, solidifying the GLA’s position as a competitive player in the burgeoning compact SUV segment.
Powertrain & Engine Architecture
At the heart of the GLA 220d 4MATIC lies the OM651.930 2.1-liter inline-four cylinder diesel engine. This engine, a mainstay in the Mercedes-Benz lineup for years, is known for its durability and efficiency. It utilizes a second-generation common rail direct injection system, delivering fuel at extremely high pressures for optimized combustion. The engine also features a variable geometry turbocharger (VGT) with an intercooler, enhancing both power and torque across a broad rev range. The 170 horsepower peak is achieved between 3400 and 4000 rpm, while the substantial 350 Nm (258 lb-ft) of torque is available from a low 1400 rpm, providing strong pulling power. The engine is paired with the 7G-DCT (7-speed dual-clutch transmission), a sophisticated gearbox that offers quick and smooth shifts. This transmission allows for both fully automatic operation and manual gear selection via steering wheel-mounted paddles.
Driving Characteristics
The GLA 220d 4MATIC delivers a composed and refined driving experience. While not overtly sporty, the 170 hp engine and 7-speed transmission provide adequate performance for everyday driving and highway cruising. Acceleration from 0 to 60 mph takes around 7.3 seconds. The 7G-DCT transmission contributes to a smooth and responsive feel, with quick gear changes enhancing the overall driving experience. The 4MATIC all-wheel-drive system provides enhanced traction and stability, particularly in adverse weather conditions. Compared to the more powerful GLA 250 models, the 220d prioritizes fuel efficiency and relaxed cruising over outright performance. The gear ratios are tuned for efficiency, with taller gearing in higher gears to reduce engine speed at highway speeds. Compared to manual transmission versions, the 7G-DCT offers greater convenience and ease of use, especially in urban traffic.
Equipment & Trim Levels
The GLA 220d 4MATIC typically came well-equipped, reflecting its premium positioning. Standard features often included automatic climate control, a multi-function steering wheel, power-adjustable front seats, and a high-resolution infotainment system with a central display screen. Safety features such as ABS, ESP, and multiple airbags were also standard. Interior upholstery was typically Artico leatherette (synthetic leather), with options for genuine leather upgrades. Optional extras included a panoramic sunroof, navigation system, premium sound system, and various driver assistance systems like blind-spot monitoring and lane-keeping assist. Trim levels varied slightly depending on the market, but generally offered packages that bundled popular options together.
Chassis & Braking
The GLA 220d 4MATIC utilizes a McPherson strut front suspension and a multi-link rear suspension, providing a comfortable and controlled ride. The suspension is tuned to balance ride comfort with handling agility. Stabilizer bars are fitted to both the front and rear axles to reduce body roll during cornering. The braking system consists of ventilated discs at the front and solid discs at the rear, providing adequate stopping power. ABS (Anti-lock Braking System) and ESP (Electronic Stability Program) are standard features, enhancing safety and stability. The 4MATIC all-wheel-drive system distributes torque between the front and rear axles as needed, optimizing traction and handling.
Market Reception & Comparison
The GLA 220d 4MATIC was generally well-received by automotive critics, who praised its fuel efficiency, comfortable ride, and refined interior. However, some reviewers noted that the engine could feel slightly underpowered when fully loaded or tackling steep hills. Compared to other trims in the GLA lineup, the 220d offered a more economical option for buyers who prioritized fuel efficiency over outright performance. Its fuel economy figures of around 39.9-38.6 US mpg combined were significantly better than those of the gasoline-powered GLA 250. In terms of reliability, the OM651 diesel engine has a generally good reputation, although regular maintenance is crucial to ensure longevity.
Legacy
The GLA 220d 4MATIC, while no longer in production, remains a popular choice in the used car market. Its combination of fuel efficiency, practicality, and Mercedes-Benz luxury continues to appeal to buyers seeking a premium compact SUV. The OM651 diesel engine, when properly maintained, is known for its durability and longevity. However, potential buyers should be aware of the potential for diesel particulate filter (DPF) issues, particularly if the vehicle has been primarily used for short trips. Overall, the GLA 220d 4MATIC represents a well-rounded and capable vehicle that offers a compelling blend of performance, efficiency, and luxury.
