Powertrain & Engine Architecture

The GLA 250 is powered by the M270.920 2.0-liter inline-four cylinder gasoline engine. This engine is a key component of Mercedes-Benz’s modular engine family, known for its compact design and efficiency. It utilizes direct fuel injection and a single turbocharger with an intercooler to deliver a balance of power and fuel economy. The engine produces 211 horsepower at 5500 rpm and 350 Nm (258 lb-ft) of torque between 1200 and 4000 rpm. The engine’s architecture features a DOHC (Dual Overhead Camshaft) valvetrain and a compression ratio of 9.8:1. The engine is transversely mounted in the front of the vehicle.

The engine is paired with a 7G-DCT (7-speed dual-clutch transmission). This transmission offers quick and smooth gear changes, contributing to both performance and efficiency. The 7G-DCT is known for its responsiveness and ability to adapt to various driving conditions. It features a wet multi-disc clutch pack and electronic control for precise gear selection.

Driving Characteristics

The GLA 250 7G-DCT offers a comfortable and refined driving experience. While not as overtly sporty as some of its competitors, it provides adequate acceleration and responsiveness for everyday driving. The 0-60 mph sprint takes approximately 6.3 seconds, and the car has a top speed of 146 mph. The 7G-DCT transmission contributes to seamless gear changes, minimizing disruptions in power delivery. The relatively high gear ratios in the 7G-DCT prioritize fuel efficiency, but can sometimes feel slightly less engaging than a traditional manual transmission. Compared to the more powerful GLA 45 AMG, the 250 offers a more relaxed and fuel-efficient driving experience. Compared to diesel variants, the 250 provides quicker acceleration but sacrifices some fuel economy.

Equipment & Trim Levels

The GLA 250 typically came standard with features such as automatic climate control, a multi-function steering wheel, power-adjustable front seats, and a touchscreen infotainment system. Interior upholstery was typically MB-Tex artificial leather, with optional genuine leather upgrades available. Common optional extras included a panoramic sunroof, navigation system, premium sound system, and various driver-assistance features like blind-spot monitoring and lane-keeping assist. Trim levels varied by market, but generally offered packages that bundled together popular options.

Chassis & Braking

The GLA 250 utilizes an independent McPherson strut suspension in the front and a multi-link suspension in the rear. This setup provides a good balance of ride comfort and handling. The front suspension incorporates a stabilizer bar to reduce body roll during cornering. Braking duties are handled by ventilated discs at the front and solid discs at the rear. ABS (Anti-lock Braking System) is standard, along with electronic brake-force distribution. The steering system is an electric power steering rack and pinion, offering precise and responsive steering feel.

Market Reception & Comparison

The GLA 250 was generally well-received by automotive critics. It was praised for its stylish design, comfortable interior, and efficient powertrain. However, some reviewers noted that the rear seat space was somewhat limited compared to other compact SUVs. In terms of fuel economy, the GLA 250 offered competitive figures, achieving around 39-41 mpg combined. Compared to the GLA 200 (a lower-powered variant), the 250 offered a noticeable performance upgrade. Compared to the GLA 220d diesel, the 250 traded some fuel efficiency for quicker acceleration and a different driving character.

Legacy

The Mercedes-Benz GLA 250 (X156, facelift 2017) has proven to be a relatively reliable vehicle in the used car market. The M270 engine, while not without its potential issues (such as carbon buildup on the intake valves), is generally considered durable when properly maintained. Regular oil changes and the use of quality fuel are crucial for long-term reliability. The 7G-DCT transmission is also generally reliable, but requires periodic servicing to ensure smooth operation. Today, the GLA 250 represents a good value proposition for buyers seeking a compact luxury SUV with a blend of style, performance, and features.
