The Mercedes-Benz B-Class (W246 facelift) B 250, produced from 2014 to 2018, represented a significant step forward in the compact luxury hatchback segment. This variant, equipped with a 2.0-liter turbocharged engine producing 211 horsepower and a 7-speed dual-clutch transmission (DCT), occupied the upper-mid-range position within the W246 facelift lineup, slotting above the B 200 and B 220 models but below potential AMG-tuned versions (which were not widely offered for this generation). The W246 B-Class, and particularly the B 250, aimed to blend practicality, comfort, and a degree of performance appealing to buyers seeking a more premium alternative to traditional compact hatchbacks.

Powertrain & Engine Architecture
The heart of the B 250 is the M 270.920 2.0-liter inline-four cylinder engine. This engine is a key member of Mercedes-Benz’s modular engine family, characterized by its all-aluminum construction, direct fuel injection, and a single turbocharger with an intercooler. The direct injection system, operating at pressures up to 200 bar, ensures precise fuel delivery for optimal combustion and efficiency. The engine utilizes a timing chain for durability and reduced maintenance compared to timing belts. The 7-speed G-DCT (Getriebe Doppelkupplungsgetriebe) dual-clutch transmission is a crucial component, offering rapid and smooth gear changes. This transmission features two separate clutches, one for even-numbered gears and one for odd-numbered gears, allowing for pre-selection of the next gear and minimizing interruption in power delivery.
Driving Characteristics
The B 250’s powertrain delivers a noticeably more engaging driving experience than the lower-powered variants. The 211 horsepower and 350 Nm (258 lb-ft) of torque provide brisk acceleration, with a 0-60 mph time of around 6.5 seconds. The DCT transmission contributes to this responsiveness, offering quick shifts and a generally sporty feel. While not a dedicated performance model, the B 250 provides ample power for everyday driving and highway overtaking. The G-DCT transmission’s gear ratios are tuned for a balance between acceleration and fuel efficiency. Compared to the manual transmission options available on other B-Class models, the DCT offers convenience and quicker shifts, but some enthusiasts might find it less involving. The B 250’s power delivery is relatively linear, with the turbocharger providing a noticeable boost in mid-range torque.
Equipment & Trim Levels
The B 250 typically came standard with features such as automatic climate control, a multi-function steering wheel, power windows and locks, and an infotainment system with a central display screen. Upholstery was generally a combination of fabric and synthetic leather, with optional upgrades to full leather available. Common optional extras included a panoramic sunroof, navigation system, premium sound system, and various driver-assistance features like parking assist and collision prevention. Trim levels within the B 250 could vary depending on the market, but generally offered packages that bundled together popular options for convenience. The interior design prioritized functionality and a modern aesthetic, with a focus on user-friendly controls and a comfortable cabin environment.
Chassis & Braking
The W246 B-Class utilizes an independent suspension setup at all four corners, with McPherson struts at the front and a multi-link arrangement at the rear. This configuration provides a good balance between ride comfort and handling. The B 250, being a higher-spec variant, often featured slightly stiffer suspension tuning compared to the base models. Braking duties are handled by ventilated discs at the front and solid discs at the rear. Anti-lock braking system (ABS) and electronic stability control (ESP) are standard safety features. The steering system employs a rack-and-pinion setup with electric power assistance. The B 250’s chassis is designed to provide a stable and predictable driving experience, prioritizing comfort and safety over outright sportiness.
Market Reception & Comparison
The B 250 was generally well-received by automotive critics, who praised its refined engine, responsive transmission, and comfortable ride. It was often seen as a more compelling alternative to traditional compact hatchbacks, offering a more premium experience. Compared to the B 200 and B 220 models, the B 250 offered a significant performance upgrade, making it a more enjoyable car to drive. However, its fuel economy was slightly lower than the lower-powered variants. Reliability reports suggest that the M 270 engine and G-DCT transmission are generally reliable, but preventative maintenance, such as regular oil changes and transmission fluid services, is crucial.
Legacy
The W246 B-Class B 250 has established itself as a solid and dependable used car option. The M 270 engine, while requiring regular maintenance, has proven to be relatively durable. The G-DCT transmission, if properly maintained, can provide years of smooth and reliable operation. Today, the B 250 offers a good value proposition for buyers seeking a practical, comfortable, and reasonably well-equipped compact hatchback with a touch of luxury. Its blend of performance, efficiency, and features continues to make it an attractive option in the used car market.
