Compared to its main rivals, the B-Class feels a step ahead. The interior is modern, well-finished and looks genuinely upmarket. Small MPVs may not be especially interesting, but the interior of the Mercedes makes this feel that little bit special.

It takes many elements from the A-Class including the neat circular air vents and the wide screen that sits across the top of the dash. The materials used all have a quality feel from the soft-touch materials to the piano black trim and the metal buttons (one of our favourite features).

It's not all style over substance though as the B-Class fills its brief as a compact MPV perfectly. It feels very spacious inside, more so than you'd expect from a car this size. It's certainly not as cramped as a BMW 2 Series Active Tourer.

Even very tall drivers will find a comfortable driving position thanks to lots of adjustment in the seat and steering column - more so than the old model - along with a high roof. The seats are quite flat yet surprisingly supportive and the fronts have an extendable under-thigh cushion.

There's equally good space in the back, much more so than the A-Class, which is ideal if you have toddlers in car seats or younger children with rear facing car seats. Here the flat seats are very helpful with the base of the child seat able to sit flush with the seat cushion.

You'd struggle to get three people in the back in comfort, the middle seat is narrow and firm while there's also a tunnel in the floor, meaning not much room for your feet.

On the plus side, the boot is usefully large and the low load lip and wide opening makes getting things like pushchairs in a doddle. From mid-2019, selected models will feature rear seats which can be moved by 14cm to vary the boot capacity between 455 and 705 litres. There's plenty of storage up front with big door pockets and a large central cubby between the front seats. 

We really like the B-Class dash, especially when you get the large glass panel with two 10-inch displays - one for the instrument cluster and the other for infotainment. It's beautifully sharp and bright. What we don't like is that it's part of the Premium Package which costs more than £2250. If you don't go for this you end up with a black plastic panel with two smaller screens. 

However, all models do come with the Mercedes-Benz MBUX system, a kind of built-in version of Amazon's Alexa. You can command it by saying ‘Hey Mercedes’ and asking it turn the air con down or the heated seats on for example. Although you could just press a button...
