Powertrain & Engine Architecture
The heart of the B 250 4MATIC is the M 260 series 2.0-liter inline-four cylinder gasoline engine. This engine utilizes direct fuel injection and is coupled with a single twin-scroll turbocharger and intercooler to enhance power and efficiency. The engine produces 224 horsepower at 5500 rpm and 350 Nm (258 lb-ft) of torque. The “Mild Hybrid” designation refers to a 48-volt electrical system that incorporates a belt-driven starter-generator. This system allows for functions like extended start-stop operation, regenerative braking (recapturing energy during deceleration), and a small power boost during acceleration. The 48V system doesn’t allow for fully electric driving, but it does contribute to improved fuel economy and reduced emissions. The engine is paired with Mercedes-Benz’s 8G-DCT (8-speed dual-clutch transmission), known for its quick and smooth shifts. The 8G-DCT is a wet dual-clutch transmission, offering improved cooling and durability compared to dry-clutch systems.
Driving Characteristics
The B 250 4MATIC offers a noticeably more spirited driving experience than lower-powered B-Class variants. The 224 hp engine and 8G-DCT transmission provide brisk acceleration, with a 0-60 mph time of around 6.2 seconds. The 4MATIC all-wheel-drive system provides enhanced traction, particularly in inclement weather conditions. The dual-clutch transmission contributes to responsive gear changes, and the mild hybrid system provides a subtle but noticeable boost during acceleration. Compared to a manual transmission equipped B-Class, the 8G-DCT prioritizes ease of use and convenience over outright driver engagement. The gear ratios are tuned for a balance of performance and fuel efficiency, with taller gears for highway cruising and shorter gears for quicker acceleration.
Equipment & Trim Levels
The B 250 4MATIC typically comes well-equipped as standard. Features generally include Mercedes-Benz’s MBUX infotainment system with a touchscreen display, Apple CarPlay and Android Auto integration, a digital instrument cluster, automatic climate control, and a suite of driver-assistance systems such as adaptive cruise control, lane-keeping assist, and automatic emergency braking. Interior upholstery is typically a combination of Artico (synthetic leather) and fabric, with options for full leather upholstery. Optional extras include a panoramic sunroof, premium sound system, head-up display, and various styling packages. The trim level sits above the B 200 and B 220 models, offering more power and standard features, but below the more performance-oriented AMG Line variants.
Chassis & Braking
The W247 B-Class utilizes a MacPherson strut front suspension and a multi-link rear suspension. The suspension is tuned for a comfortable ride, while still providing adequate handling. The 4MATIC all-wheel-drive system employs a multi-plate clutch to distribute torque between the front and rear axles as needed. Braking duties are handled by ventilated discs at the front and solid discs at the rear. The B 250 4MATIC is equipped with ABS (Anti-lock Braking System), Electronic Stability Program (ESP), and other safety features. Steering is via a power-assisted rack and pinion system.
Market Reception & Comparison
The B 250 4MATIC was generally well-received by automotive critics. Reviewers praised its blend of performance, practicality, and fuel efficiency. The MBUX infotainment system was also a highlight, lauded for its ease of use and advanced features. Compared to the lower-powered B 200 and B 220 models, the B 250 4MATIC offered a significant performance upgrade, making it a more appealing option for drivers who prioritize acceleration and responsiveness. Fuel economy, while respectable, was slightly lower than the less powerful variants due to the increased output. Reliability reports have been generally positive, with the M 260 engine proving to be a robust and dependable unit.
Legacy
The B 250 4MATIC, as part of the W247 facelift, represents a refinement of the B-Class formula. The integration of mild hybrid technology demonstrates Mercedes-Benz’s commitment to improving fuel efficiency and reducing emissions. On the used car market, these models are sought after for their combination of features, performance, and relative reliability. The 8G-DCT transmission, while requiring periodic maintenance, has proven to be a durable unit when properly serviced. The B 250 4MATIC continues to offer a compelling option for buyers seeking a premium compact MPV with a balance of practicality and driving enjoyment.
