Mercedes-Benz B-Class (2019-present) Pros and Cons

Pros	Cons
Roomy and practical cabin	Cheaper MPVs offer more space with a humble badge
Tax-efficient plug-in hybrid	Not very exciting to drive
Comfortable ride	Plain-looking exterior

Quick Summary

The Mercedes-Benz B-Class (2019-present) is an upmarket, five-seat MPV that prioritises comfort and practicality over driving excitement. The third-generation model launched to positive reviews, featuring the impressive MBUX infotainment system with pin-sharp twin-screen displays, comprehensive driver aids, and a roomy interior with excellent rear-seat legroom. Boot space is respectable at 455 litres, expanding to 705 litres with rear seats slid forward. The cabin features soft-touch materials and a premium ambience, though some lower-door plastics are less plush. The ride is smooth and absorbing, making it ideal for relaxed, fuss-free progress, whilst the cabin remains quiet at motorway speeds.

Engine options include efficient diesels (B180d, B200d, B220d) achieving 53-55mpg, petrol variants (B180, B200, B250) returning 40-46mpg, and the standout B250e plug-in hybrid with 42 miles of electric range and an official combined figure of 235.4mpg. The 2022 facelift simplified the range to B200 and B200d only for new purchases. Running costs vary by engine choice, with diesel models offering the best economy for higher mileage drivers, whilst the PHEV suits those with lower daily mileage and home charging. Insurance groups range from 19-31 depending on specification. Sport Executive trim offers excellent value with comprehensive equipment, making it the recommended specification.

Best for: Buyers seeking an upmarket, practical family car with premium interior finish, those prioritising comfort over driving dynamics, and company car drivers considering the tax-efficient plug-in hybrid.

Not ideal for: Drivers wanting maximum space at the lowest price, those seeking an exciting driving experience, or buyers preferring distinctive exterior styling.


Comparison vs Key Rivals



The Verdict

You should buy the B-Class if: You seek an upmarket, practical family car with premium interior finish, prioritise comfort over driving dynamics, or are a company car driver considering the tax-efficient plug-in hybrid.

Consider alternatives if: You want maximum space at the lowest price, seek an exciting driving experience, or prefer distinctive exterior styling.

Competitive Position: The Mercedes-Benz B-Class (2019-present) stands out in the MPV segment as a premium, comfort-focused alternative to more utilitarian rivals. Whilst the Volkswagen Golf Mk7 and Ford C-Max achieve higher user ratings, and the BMW 2 Series offers better value deals, the B-Class delivers superior interior quality and the unique appeal of the Mercedes badge. It's more expensive than spacious alternatives like the Citroën Grand C4 Space Tourer or Ford S-Max, but compensates with exceptional cabin ambience and the option of a highly efficient plug-in hybrid. For buyers valuing understatement, premium materials, and practical comfort over maximum space or driving thrills, the B-Class remains a compelling choice.
