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

Pros	Cons
Roomy and practical cabin	There are cheaper MPVs with even more space, if you can live 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 a third-generation five-seat MPV, offering a blend of high-tech driver aids, the spectacular MBUX infotainment system, and comfortable motoring. Significantly larger and wider than the A-Class, it provides excellent rear-seat legroom and headroom. Non-hybrid models boast a respectable 455 litres of boot space, expandable to a whopping 705 litres with sliding rear seats, which also split and fold 40/20/40. The interior features a posh, high-quality feel, dominated by the pin-sharp twin-screen MBUX display.

While not designed for an exciting drive, the B-Class prioritises comfort with a smooth, bump-absorbing ride and a quiet cabin, making it ideal for relaxing journeys. Engine options range from efficient diesels and petrols to a highly tax-efficient B250e plug-in hybrid with a 42-mile electric range. Running costs vary, with the PHEV being cheapest for low mileage and diesels for higher mileage. Entry-level Sport models are well-equipped, but Sport Executive adds valuable features like Apple CarPlay, Android Auto, and parking sensors.

Best for: Drivers seeking an upmarket, practical, and comfortable family car with advanced technology, those who prefer understatement over ostentation, and company car drivers interested in the tax-efficient plug-in hybrid.

Not ideal for: Buyers prioritising an exciting driving experience, those on a very tight budget who need the absolute cheapest MPV, or those who prefer a more visually dynamic exterior design.


Comparison vs Key Rivals



The Verdict

You should buy the B-Class if: You seek an upmarket, practical, and comfortable family car with advanced technology, prefer understatement, or are a company car driver looking for a tax-efficient plug-in hybrid.

Consider alternatives if: You prioritise an exciting driving experience, are on a very tight budget for an MPV, or prefer a more dynamic exterior design.

Competitive Position: The Mercedes-Benz B-Class holds a unique position as a premium MPV, offering a luxurious interior, advanced MBUX infotainment, and a highly comfortable ride. While more affordable MPVs exist with potentially more seats or space, they lack the cachet and interior refinement of the B-Class. Its range of efficient engines, including a compelling plug-in hybrid, makes it a sensible choice for various drivers, particularly those seeking a practical family car that stands apart from the SUV crowd without sacrificing quality or technology.
