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 the third-generation of Mercedes' five-seat MPV, launched in late 2018. It features high-tech driver aids, the impressive MBUX infotainment system, and initially offered RDE2-compliant diesel engines. Despite the rise of SUVs, the B-Class excels in practicality, being longer and wider than the A-Class, offering generous rear-seat legroom and headroom. Its boot provides 455 litres of space, expanding to 705 litres with sliding rear seats, which also feature a 40/20/40 split. The interior delivers a premium ambience with soft-touch materials and twin-screen displays.

From the driver's seat, the B-Class prioritises comfort with a smooth, bump-absorbing ride and a quiet cabin, making it ideal for relaxed driving. A wide range of engines has been offered, including efficient diesels, petrols, and a tax-efficient B250e plug-in hybrid with a 42-mile electric range. While newer models have a pared-down engine range, the used market offers more choice. Running costs vary, with the PHEV being cheapest for low mileage users and diesels for higher mileage. Insurance groups range from 19-31 depending on the variant.

Best for: Drivers seeking an upmarket, practical, and comfortable family car with understated appeal, or those looking for a tax-efficient plug-in hybrid option.

Not ideal for: Buyers prioritising an exciting, sporty drive, or those who need a larger MPV with an extra row of seats.

Competitive Position: The Mercedes-Benz B-Class (2019-present) occupies a unique space as an upmarket, practical, and comfortable five-seat MPV. While not as large as some seven-seat rivals or as dynamically engaging as sportier hatchbacks, it offers a premium interior, advanced technology, and excellent cabin space. Its flexible boot and tax-efficient plug-in hybrid option make it a compelling choice for families prioritising sophistication, comfort, and practicality over ostentation or outright performance in the increasingly SUV-dominated market.
