The Mercedes B-Class is a tall, spacious family car that’s easy to drive and a good alternative to many modern SUVs. You’ll have to pay extra for lots of key features, though

Why not test drive the Mercedes B-Class yourself at a dealer near you?

If you like the idea of a car with a high seating position and a flashy interior but don’t want an SUV, then the Mercedes B-Class will be right up your street. Its smooth design is a refreshing alternative to the usual crop of off-road styled SUVs and it even looks pretty sporty in AMG-Line trim with lowered suspension.

The Mercedes B-Class has a taller body than most small hatchbacks, but its neat curvy styling makes sure it still looks pretty sleek – it’s certainly not something you’d be embarrassed to park on your driveway in a neighbourhood full of posh compact SUVs.

It’s a similar story in the Mercedes B-Class’ cabin, where a set of neat metal air vents and dual infotainment displays – that come as standard by the way – make it feel a bit more sci-fi blockbuster than the B-movie interior you’ll find in the BMW 2 Series Active Tourer. Especially if you pay extra to have the standard 7.0-inch screens replaced by a pair of huge 10-inch items.

Also adding to the Mercedes’ futuristic-feeling cabin is 64-colour mood lighting – perfect for bathing its cabin in a particularly lurid shade of orange – and some great big slabs of brushed metal-effect plastic on the dashboard.

It doesn’t look that exciting on the outside, but that interior puts the B-Class head-and-shoulders above its competition

It’s not just a pretty face, though – the Mercedes B-Class’ cabin is very easy to live with. There’s absolutely loads of room for you to stretch out in the front if you’re tall – even if the seats are a little flat and unsupportive – and there’s still space left over in the back for a couple of six-footers to get comfy.

The boot’s a decent size too, and you’ll soon be able to get the Mercedes B-Class with some clever sliding rear seats that’ll let you trade some passenger knee room for a bit of extra boot space.

Also helping make the B-Class easy to live with is the standard automatic gearbox that’ll take heavy traffic in its stride. It’s also reasonably comfortable to drive around town and dead easy to see out of. Sure, it isn’t as nimble as the BMW 2 Series Active Tourer but it’s more relaxing to drive and the diesel engine in B200 d models is a real gem – it’s quiet, punchy and still pretty cheap to run so there isn’t any need to pay extra for the more powerful B220 d model.

A couple of options are worth considering, though. These include some advanced driver assistance systems that’ll change lanes for you automatically and even adjust the cruise control settings to slow you down as you approach junctions and tight corners.

Of course, these options don’t come cheap. You can always save yourself some money by comparing offers on our Mercedes B-Class deals page, though. If you want more in-depth info, read our following interior, practicality, driving and specifications review sections.
