The Mercedes-Benz B-Class is a compact SUV that is really spacious and practical. There’s much to like about people carriers – and the B-Class is a great option. If you are considering a used new one, you will find everything you need to know here, including a full account of the current model line-up.
There are also plenty of used Mercedes-Benz B-Class models available to buy. While you’re here, why not check out the selection of cars we have in stock?
MPVs are all about space and practicality, and the B-Class scores very well on those fronts. It’s quite a tall car, so even people well over six feet should be able to get comfortable in the front and back. Children are unlikely to have any complaints about space in the back either; two rear-facing child seats are easily installed on the Isofix mounts. Big windows let in plenty of light and give a good view out, so it’s a nice car to travel in.
There are other MPVs this size that offer a bigger boot, but you still get considerably more load capacity than in most medium-sized hatchbacks – you won’t have to worry about packing light for a family holiday. The back seats fold down if you need even more space.
The B-Class’s compact size means it’s easy to drive around town and is also a fine long-distance cruiser, especially as an automatic gearbox is fitted as standard. It comes with some impressive technology, too. There are four trim levels, plus two petrol and two diesel engines to choose from. Any of the combinations will get you a well-equipped, fuel-efficient car.
Running costs are low, especially if you go for the diesel engine, which can manage well over 50mpg. Mercedes-Benz cars are usually very reliable and solidly put together, so the B-Class should be largely trouble-free to own.
The B-Class’s main rivals are the BMW 2 Series Active Tourer and Volkswagen Touran. They all have similar passenger and boot space, so the choice may come down to which one you prefer the look and feel of. If you like the B-Class most, you’re unlikely to be disappointed.

Mercedes-Benz model badges make no mention of engine size any more. The B180 isn’t a 1.8-litre motor: it’s actually a 1.3-litre turbo. The B200 is a higher-powered 1.3-litre, while the B180d is a 1.5-litre diesel. The B250, B200d and B220d are 2.0-litre engines.
Don’t worry. The turbocharged motors have surprising power, and the B180 offers perfectly reasonably pace. We’d happily drive one, and even find the regular Sport trim more than acceptable. AMG Line spec looks sportier, but that’s arguably irrelevant for an MPV. Meanwhile, if you want more kit you can get the Executive upgrade pack on Sport, and Executive, Premium or Premium Plus packs on AMG Line (it’s less confusing than it sounds).
As of 2022, the B-Class engine range was slimmed down - this is increasingly becoming the case due to ongoing supply issues and brands 'rightsizing' ranges. Only the B200 and B200d engines were now available - thankfully they're probably the best all-rounders anyway.
The range of engines available in the B-Class was reduced in 2022, down to one petrol and one diesel. In both cases, Mercedes chose to continue with the more powerful options, which sold in greater numbers anyway. Both engines offer similar performance and produce similar CO2 emissions, but the diesel posts higher fuel economy figures. It could be the better option if you cover a lot of miles.
The B-Class is available with a number of trim levels that act as a starting point. Different packages of extra features could be added when the car was bought new. The Sport and AMG Line trims come very well equipped anyway, but the extra features you get with the packages could be genuinely useful to you. The current B-Class has been on sale since 2019.
The Mercedes-Benz B-Class’s exterior dimensions are:
The Mercedes-Benz B-Class’s boot capacity is:
As an alternative fuel vehicle, the Mercedes B250e plug-in hybrid qualifies for a discount on its road tax, so it pays £170 per year for 12 months of duty. All the others in the B-Class range will cost you the standard, at the time of writing, £180 per year.
The B-Class is rated in insurance groups 22 to 26, roughly in the middle of the 1-50 scale. It might cost more to insure than some other mid-size MPVs, but not by a huge amount.
