4.0 out of 5

The Mercedes B-Class is more spacious and airy than ever, with a pretty generous boot and flexible seating arrangements. There are ISOFIX points in the rear only, suitable for two child seats.

Mercedes B-Class interior space & storage

The B-Class feels spacious in both the front and back – three children can sit side side-by-side in the rear without feeling cramped, and it's easy for everyone to get in and out. Headroom has been increased compared to the old model, even though the new car isn't as tall.

Front-seat occupants have a generous amount of room to stretch out. Rear legroom is also impressive, and can be increased further at the expense of boot space.

The door bins are large and there are two large cubbies in the centre console for odds and ends. The glovebox isn't as large as we'd like, though.

Boot space

The boot is a practical shape – it has a wide opening with a small lip. It offers 488 litres of space – slightly more than the Ford C-MAX.

Fold down the rear seats and that space swells to 1,545 litres, which should be enough for most families, but isn’t quite as much as the C-MAX's 1,723 litres. The rear seats in all models have a 60:40 split-folding arrangement.

The entry-level SE model includes the Easy Vario Plus Package. This includes a sliding rear bench seat, which can be used to increase either rear legroom or boot space as needed.

The package also brings a height-adjustable boot floor and a folding armrest with two cup-holders. The boot floor doesn't alter the boot space hugely, but it is useful for hiding valuables away.


The B-Class offers a maximum towing weight of 1,200-1,500kg, depending on engine power.
