Mercedes-Benz B-Class Review 2022

Mercedes-Benz B-Class At A Glance


+Very comfortable and relaxed to travel in. Lots of interior space in a reasonably compact package. Has new excellent MBUX system. High quality interior design and finish.

-Styling will not appeal to everyone. Automatic in petrols can be hesitant at low speeds.

New prices start from £36,845

In a world where SUVs have become the family car of choice for most people, it seems the days of the MPV are numbered. But if that's the case, no one has told Mercedes-Benz. Because the B-Class is now in its third generation and Mercedes is aiming it at a younger market.

In terms of the looks, it's not going to win any style contests, but what the B-Class does have is one of the best interiors around. Against the competition like the BMW 2 Series Active Tourer and Volkswagen Golf SV, the B-Class has a much fresher and more appealing cabin.

There's plenty of standard kit, including navigation, smartphone integration and the new Mercedes MBUX system. This is a voice controlled infotainment assistant which responds to commands when you say 'Hey Mercedes'. Kind of like Alexa but on the move.

With a similar style to the excellent A-Class, it's not just the design that impresses but also the feel of the materials used and the quality of the finish. There's plenty of space too and it feels more roomy inside than you'd expect of a compact MPV.

The B-Class certainly creates a relaxing and serene environment to travel in, with comfortable seats, little wind noise and excellent ride quality. It's arguably more comfortable than the competition from BMW and Volkswagen.

Yet it still handles well with lots of grip and is surprisingly keen in corners with not much in the way of lean.  

The boot is usefully large too and more than big enough to cope with what a family can throw at it everyday. The wide boot opening and low lip mean getting awkward things like pushchairs in the back is easy.

The cheapest model is the B 180 petrol, powered by a 1.3-litre engine (yes, Mercedes-Benz badging has reached peak meaningless). This four-cylinder unit may seem far too small for a car this size, but with 136PS it actually provides more than enough power to give the B-Class a good turn of pace when needed. Only a hesitant automatic lets it down but luckily there's a manual available.

There are also diesels, including the B 200 d which has a claimed average economy of more than 50mpg. This is a quiet and refined engine, that also responds eagerly to throttle inputs.

Currently there's no hybrid or PHEV models but expect that to change in the not too distant future.

What is AdBlue and what does it do?
"I currently have a 2014 Mercedes-Benz C-Class diesel and I am waiting delivery of a new B-Class 180d. I prefer Mercedes diesels to Renault petrol engines. Because I only do around 8,000 miles per year what action do I need to take keep the engine in tip-top condition? What is AdBlue and what does it do? Lastly, my current C-Class averages about 50mpg, whereas a petrol model does about 40mpg to 45mpg, so is the diesel better for the environment because it goes further on the same amount of fuel?"
A modern diesel likes regular motorway runs to keep its DPF filter in tip top condition. Our sister website published a guide on DPFs that is worth reading: Find out about AdBlue here: Petrols are considered to be better for the environment because they produce less harmful gases.

Is there any reason to buy a Mercedes B-Class to replace my Vauxhall Meriva apart from badge prestige?
"I'm looking to replace a Meriva A and am looking at a Meriva B, which seems the best value to buy used. A Dacia Logan, which is slightly more expensive used, is cheaper to run. A Mercedes-Benz B-Class is more expensive to buy and run - but is there any reason to pay more for the Mercedes apart from badge prestige?"
The B-Class will have a much more premium interior and is better to drive than the Logan and Meriva. It depends whether you want value for money or something a bit more luxurious.

What's the best car for an elderly driver who needs a wheelchair?
"I have a relative who is about 70 years old and she is looking to change her car and would like some advice. She often takes her mother out who is not very mobile and obviously of mature years, therefore they take a conventional wheelchair with them. She requires a vehicle with a low loading point at the rear to put wheelchair in. The wheelchair folds together so can be laid flat, but is heavy to lift for a female, also needs quite wide passenger door for mother to get in and out. She doesn't want a van or a 4x4 (generally too high to enter) but would entertain hatchback or more probably an estate. Preferably new but might entertain used up to say £30,000. "
We recently drove the new Mercedes-Benz B-Class and think it might suit your relative well. It's got a comfortable, high-up seating position, a big boot with a low lip and a very upmarket interior. Alternatively, a more conventional estate like the Skoda Octavia might work well.
