Powertrain & Engine Architecture
The GLA 220 CDI was powered by the OM651.930, a 2.1-liter inline-four diesel engine. This engine was a mainstay in the Mercedes-Benz lineup, known for its robust construction and fuel efficiency. It featured a common rail direct injection system, delivering fuel at extremely high pressures for optimized combustion. The engine also incorporated a turbocharger with an intercooler, boosting power output and improving throttle response. The valvetrain employed a double overhead camshaft (DOHC) design with four valves per cylinder, enhancing volumetric efficiency. The engine produced 170 horsepower at 3400-4000 rpm and 350 Nm (258 lb-ft) of torque between 1400-3400 rpm. This torque curve provided strong low-end and mid-range acceleration, making it well-suited for everyday driving. The engine was paired with a 7G-DCT (7-speed dual-clutch transmission). This transmission offered quick and smooth gear changes, contributing to both performance and fuel economy. The dual-clutch design allowed for pre-selection of the next gear, minimizing interruption in power delivery.
Driving Characteristics
The GLA 220 CDI with the 7G-DCT offered a comfortable and refined driving experience. While not a performance-oriented variant, the engine’s torque output provided adequate acceleration for most situations. The 0-60 mph time of around 7.9 seconds was respectable for a compact diesel SUV. The 7G-DCT transmission contributed to seamless gear changes, enhancing the overall driving feel. Compared to the higher-output GLA 250 (gasoline), the 220 CDI prioritized fuel efficiency over outright speed. The manual transmission versions of the 220 CDI offered slightly more driver engagement, but the 7G-DCT provided greater convenience, particularly in urban environments. The gear ratios were tuned for fuel economy, with taller gearing in higher gears to reduce engine speed at cruising speeds. The front-wheel-drive configuration provided predictable handling, although it lacked the all-weather capability of the available 4MATIC all-wheel-drive system.
Equipment & Trim Levels
The GLA 220 CDI typically came standard with features such as automatic climate control, a multi-function steering wheel, and a basic infotainment system with a central display screen. Upholstery was generally cloth, although leather options were available. Optional extras included a panoramic sunroof, navigation system, upgraded audio system, and various driver assistance features like parking sensors and lane keeping assist. Trim levels varied depending on the market, but generally offered packages that bundled together popular options. The interior design was modern and functional, reflecting Mercedes-Benz’s design language at the time. The dashboard layout was clean and intuitive, with logically placed controls.
Chassis & Braking
The GLA 220 CDI utilized an independent McPherson strut suspension at the front and a multi-link suspension at the rear. This setup provided a good balance between ride comfort and handling. A stabilizer bar was included at both ends to reduce body roll during cornering. The braking system consisted of ventilated discs at the front and solid discs at the rear. Anti-lock braking system (ABS) was standard, along with electronic brakeforce distribution (EBD). The suspension was tuned to prioritize comfort, but it still offered decent handling characteristics for a compact SUV. The steering was electrically assisted, providing light and precise steering feel.
Market Reception & Comparison
The GLA 220 CDI was well-received in Europe, where diesel engines were popular due to their fuel efficiency and lower running costs. Critics praised the car’s comfortable ride, refined interior, and economical engine. However, some noted that the performance was not as exciting as some of its gasoline-powered rivals. Compared to the GLA 200 d (a lower-powered diesel variant), the 220 CDI offered a noticeable performance upgrade. Against the GLA 250, the 220 CDI traded some performance for significantly better fuel economy. The 220 CDI’s fuel economy figures of 4.4-4.6 l/100 km (53.5-51.1 US mpg) were a major selling point, making it an attractive option for drivers who covered long distances.
Legacy
The OM651 engine family, including the OM651.930 found in the GLA 220 CDI, has proven to be remarkably durable and reliable. With proper maintenance, these engines can accumulate high mileage without major issues. The 7G-DCT transmission is also generally considered reliable, although regular fluid changes are essential. In the used car market, the GLA 220 CDI remains a popular choice for those seeking a fuel-efficient and well-equipped compact SUV. Its combination of practicality, comfort, and reliability has ensured its continued appeal. 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 220 CDI represents a solid and dependable option within the compact SUV segment.
