How much does the Mercedes Benz B Class cost to run?

The 1.5L diesel is the most economical Mercedes Benz B Class to run, taking into account insurance, tax and fuel efficiency.

The Mercedes Benz B Class 1.5L diesel is free to tax, as it sits in tax band A.

It does not far off 79 MPG on average, which means it will cost £8.00* in diesel every 100 miles driven.

In terms of fuel efficiency, it sits between the Peugeot 308 1.6L diesel and the more thirsty Ford Focus 1.6L diesel.

The lower the insurance group, the cheaper a car should be to insure. This model is rated insurance group 15, which is lower than the Citroen C4 1.6L diesel, but higher than the Ford Focus 1.5L diesel. (If insurance cost is important to you then the Honda Civic has the lowest insurance group.)

Mercedes Benz B Class: How big is the boot?

The Mercedes Benz B Class hatchback has a bigger boot than the MPV (it can hold 544 litres of luggage with the seats up).

This allows the hatchback to take one pushchair and 3 large bags or 4 large bags. While the MPV takes just 4 large bags.

Worth knowing, the Peugeot 308 estate is the best in class, allowing for one pushchair and 5 large bags with its 810 litres.

Is the Mercedes Benz B Class easy to park?

The Mercedes Benz B Class is very middle of the road - it fills three quarters of a space. There are lots of wider cars, but just as many that are narrower and feel easier to park. For example, the Skoda Rapid.

If you don’t park in the street that much, then the B Class is fine. It will go in to an average street slot, giving you a gap of 414mm to swing in and out. But if you street park a lot you may want to look at the Suzuki Baleno.

Which Mercedes Benz B Class has the best performance?

The fastest Mercedes Benz B Class from 0-60, is the 2.0L diesel (if you’re a petrol head, it has 400 lbs/ft torque and 190 bhp). It hits 60 mph in 7.2 seconds.

The closest rival in its class is the Audi A3 1.8L petrol, which will beat your Mercedes Benz B Class to 60 by 0.1 seconds. That’s a big gap in Formula 1, but not something you would notice in your commute to work.

What size caravan or trailer, can the Mercedes Benz B Class tow?

If you are towing you want good torque to pull away easily despite the extra weight, and the car needs to be at least 15% heavier than the caravan to keep you stable at speed.

The model that can tow the biggest caravan or heaviest trailer is the Mercedes Benz B Class 2.0L diesel which has 400 lbs/ft torque. It should be able to tow a braked caravan or trailer that weighs up to 1600kg comfortably.

You must check your car handbook – maximum towing weights vary considerably with different engine and gearbox combinations.
