The Mercedes-Benz B 160 CDI, produced between 2013 and 2014, was a front-wheel-drive compact hatchback forming part of the W246 series B-Class. Positioned as the entry-level diesel variant, it aimed to provide fuel efficiency and practicality within the broader B-Class range. This model utilized a 1.5-liter turbocharged diesel engine paired with a 7-speed dual-clutch transmission (DCT), offering a balance between affordability and modern technology. It was primarily marketed in Europe, where compact hatchbacks with diesel engines were highly popular due to fuel costs and emissions regulations.

Powertrain & Engine Architecture
The B 160 CDI was powered by the OM607.951 engine, a 1.5-liter inline-four cylinder diesel. This engine was part of Mercedes-Benz’s efforts to downsize and improve fuel economy. It featured a turbocharger with an intercooler to boost power output, and a common rail direct fuel injection system for precise fuel delivery. The engine produced 90 horsepower at 2750-4000 rpm and 240 Nm (177 lb-ft) of torque between 1700-2500 rpm. The 7-speed G-DCT dual-clutch transmission provided quick and smooth gear changes, contributing to both efficiency and a more engaging driving experience compared to a traditional automatic. The DCT’s programming prioritized fuel economy, with taller gear ratios in the higher gears.
Driving Characteristics
The B 160 CDI Automatic offered a comfortable and practical driving experience, but wasn’t designed for performance. Acceleration from 0-60 mph took around 13.3 seconds, and top speed was limited to 111.85 mph. The engine’s torque was readily available from low revs, making it suitable for everyday driving and overtaking maneuvers. However, the 90 hp output meant that the engine could feel strained when fully loaded or climbing steep hills. The DCT transmission generally shifted smoothly, but could occasionally exhibit some hesitation at lower speeds. Compared to the more powerful B 200 CDI or petrol-powered variants, the B 160 CDI prioritized fuel economy over outright performance.
Equipment & Trim Levels
The B 160 CDI typically came with a reasonable level of standard equipment. This included air conditioning, a multi-function steering wheel, electric windows, and a basic audio system. Safety features such as ABS, ESP (Electronic Stability Program), and multiple airbags were also standard. Interior upholstery was typically cloth, with options for leather upgrades. Optional extras included a panoramic sunroof, navigation system, parking sensors, and upgraded audio systems. The trim level was generally considered entry-level within the B-Class range, focusing on providing essential features at an affordable price point.
Chassis & Braking
The W246 B-Class featured a McPherson strut front suspension and a trailing arm rear suspension. This setup provided a good balance between ride comfort and handling. The B 160 CDI utilized ventilated disc brakes at the front and solid disc brakes at the rear. The braking system was adequate for the vehicle’s weight and performance, and was assisted by ABS and ESP. The electric power steering provided light and precise steering feel, making it easy to maneuver in urban environments.
Market Reception & Comparison
The B 160 CDI was generally well-received by critics as a practical and fuel-efficient option. However, some reviewers noted its lack of outright performance. Compared to the B 200 CDI, which offered significantly more power, the B 160 CDI was seen as a more sensible choice for drivers prioritizing economy. Fuel economy figures of 53.5-57.4 US mpg combined were a major selling point. Reliability was generally good, although like all diesel engines, the particulate filter could require occasional maintenance. The B 160 CDI offered a competitive alternative to other compact hatchbacks in Europe, such as the Volkswagen Golf and Ford Focus.
Legacy
The B 160 CDI, while not the most powerful or exciting variant of the W246 B-Class, remains a popular choice on the used car market due to its fuel efficiency and practicality. The OM607.951 engine is known for its durability, although regular maintenance is essential to ensure long-term reliability. The 7-speed G-DCT transmission has also proven to be relatively reliable, provided it has been serviced according to Mercedes-Benz’s recommendations. Today, these vehicles represent an affordable entry point into Mercedes-Benz ownership, offering a comfortable and economical driving experience.
