The Mercedes B-Class is a small MPV that’s based on the current Mercedes A-Class hatchback. Taller, wider and longer, the B-Class aims to blend the quality, refinement and hi-tech interior of the A-Class with greater space and practicality.

The B-Class closely competes against models such as the BMW 2 Series Active Tourer, which is arguably the Mercedes' closest rival. Other models in this relatively small class are the Volkswagen Golf SV and Toyota Prius+. However, unlike the BMW 2 Series Gran Tourer, the Mercedes offers no seven-seat alternative - unless you look at the Mercedes GLB SUV.

Best MPVs to buy

Viewed head on, the B-Class looks every inch a taller A-Class – a description that actually nails exactly how it shapes up as a package. Swing a wide-opening door open and you're greeted by an interior that shares the same classy style and attractive detailing as the A-Class hatchback that won it much praise when it was launched in 2019.

Some of that praise was directed at the MBUX infotainment system, soon to become a feature across the entire Mercedes range, and it’s as easy to use as it is good to look at. All the must-have connectivity options are available, either as standard equipment or via the options list.

The range of diesel engines includes the 114bhp B 180 d, 148bhp B 200 d and the 188bhp B 220 d diesels, along with three petrol models particularly suited to buyers who cover a low to medium annual mileage.

Of the petrol engine variants, the 161bhp B 200 impressed us with its perky performance, with the standard seven-speed dual-clutch automatic gearbox proving smooth if occasionally hesitant on the move. A manual gearbox option is expected later on, as is Mercedes' 4MATIC four-wheel drive system.

The most powerful petrol engine isn’t the most efficient, barely struggling to top 40mpg under the WLTP economy measurement regime, but the Mercedes' 2.0-litre diesel engine – used by the B 200 d and B 220 d - is certified to Real Driving Emissions 2 (RDE2) standards, which means a lower Benefit-in-Kind (BiK) rate than some rival cars.

If you fear that the extra practicality the B-Class offers over the A-Class will come at the expense of driving pleasure, you needn't worry. From behind the wheel, the B-Class feels just like a taller hatchback, and one with a clearer view of the road ahead. Although the suspension design is dependent on which model you buy, the B 200 we drove disguised its bulk very well, with plenty of grip and little tendency to lean in corners, even if steering feel is in short supply. In AMG Line trim, the ride is also slightly stiffer, especially at lower speeds in town, where the BMW feels a bit more composed.

Rather more generous is the interior space on offer in the B-Class, which combines with the high-set seating and four wide-opening doors to exist as one of the car’s main selling points. The boot is big, too, and a van-like load bay is available if you fold the rear seats down. However – none of these qualities are hugely unusual or elusive; there are family estate cars out there which will beat the B-Class for boot space and practicality.

Before long, Mercedes will release a version of the B-Class with sliding rear seats that can be positioned to prioritise space for passengers or packages, lending the MPV a welcome dose of versatility. As it is, the interior of the B-Class lacks some of the innovation of several of its MPV and SUV rivals. Furthermore, not only does the BMW 2 Series Active Tourer offer seats for up to seven, there’s also a plug-in hybrid engine option.

However, think of the B-Class as the taller, more spacious A-Class it really is, and it makes more sense. It's not a true MPV but for those who want an interior that's spacious and easy to use in a car with a premium badge, the B-Class makes a classy choice.
