How is the quality and layout?

The interior of the B-Class impresses when you jump behind the wheel. You don’t feel like you’re sitting on top of the seat looking down on everything and, thanks to a dashboard shared with the A-Class hatchback, it looks suitably upmarket and modern.

There are nice squashy plastics on the top of the dash and smart bits of piano black or aluminium-look trim; however, move your eyeline downwards and you’ll notice rather more inexpensive bits of cheap plastic, especially on the door bins. Even the climate control buttons feel cheap when you touch them, but the vents are attractive with a turbine design. A BMW 2 Series Active Tourer, feels better screwed together.

Mercedes B-Class driver's display
You can configure the driver’s display in all manner of ways via the right-hand steering wheel spoke.

At least you do get physical controls for the heating, drive modes, stereo’s volume and a button to bring up the parking assistance systems. Pretty much everything else is controlled by the touchscreen we’ll come onto below, and touch-sensitive controls on the steering wheel. These prove far fiddlier than conventional buttons and scroll wheels, and are easier to press by accident when you’re turning the steering.

Infotainment and tech

The twin 10.25-inch digital screens are easy to read with sharp graphics, but they are susceptible to glare. The driver’s display can show traditional dials with trip data, music choice, sat nav maps and other info in the middle, or a selection of other styles. These are arguably harder to read, while scrolling through the system’s menu is made harder by the touch-sensitive control on the steering wheel you have to use.

There are also touch-sensitive icons for the cruise control, stereo and for the main infotainment screen, making for a busy wheel that’s tricky to operate by touch alone. The main touchscreen is responsive with logical menus and most icons are large enough to press with ease. Android Auto and Apple CarPlay are included as standard, as is sat nav.

Mercedes B-Class infotainment
An infotainment update in 2023 ditched the central touchpad. You now control the screen via touch or the left steering wheel spoke.

The heating control buttons are set low on the dashboard, and the digits for the temperature are on the infotainment screen, meaning you can’t quickly look at what the temperature is set to. Not ideal. Plus the fan setting button is a bit of a stretch for the driver. Thankfully Mercedes’ voice control is very good and capable of many functions. Just don’t say ‘Mercedes’ in the car, that’s usually enough to set it off.


  • Front seats firm but supportive
  • Heated on all models, electrically adjustable on top-spec
  • Manual seat controls fiddly

Comfort should be one of the B-Class’s best areas, and to a degree Mercedes has succeeded. The seats in the front offer a good amount of adjustment and visibility is good, however some may find them too firm, and ones with manual controls can be fiddly to adjust to the perfect driving position.

However, extendable seat bases mean there’s more support for your legs, and if you spend extra on the electric seats there’s an extra degree of adjustability.
