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

The 2.1L diesel is the most economical Mercedes Benz M Class to run, taking into account insurance, tax and fuel efficiency.

The Mercedes Benz M Class 2.1L diesel costs £200.00 a year to tax, as it sits in tax band G.

It does just over 47 MPG on average, which means it will cost £13.00* in diesel every 100 miles driven.

In terms of fuel efficiency, it sits between the Jaguar F Pace 2.0L diesel and the more thirsty Hyundai Santa Fe 2.2L diesel.

The lower the insurance group, the cheaper a car should be to insure. This model is rated insurance group 38, which is lower than the Hyundai Santa Fe 2.2L diesel, but higher than the Audi Q7 3.0L diesel. (If insurance cost is important to you then the Hyundai Santa Fe has the lowest insurance group.)

Mercedes Benz M Class: How big is the boot?

The Mercedes Benz M Class has an above average boot space (742 litres of luggage with the seats up).

This would allow one pushchair and 5 large bags. Alternatively you could load up with 6 large bags or 6 cabin bags instead.

Worth knowing, the Land Rover Discovery SUV is the best in class, allowing for one pushchair and 6 large bags with its 889 litres.

Is the Mercedes Benz M Class easy to park?

While not the absolute narrowest car (that is the Mitsubishi Shogun), this is in the top third for ease of parking in car parks. Given a typical supermarket space, it will fill just over three quarters of the space.

If you park on the street regularly, this is one of the cars to shortlist. At 4795m long it gives you reasonable 5mm space to move the car in and out of the bay.

Which Mercedes Benz M Class has the best performance?

The fastest Mercedes Benz M Class from 0-60, is the 4.0L diesel (if you’re a petrol head, it has 700 lbs/ft torque and 306 bhp). It hits 60 mph in 6.5 seconds.

The closest rival in its class is the Audi Q7 4.1L diesel, which will beat your Mercedes Benz M 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 M 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 M Class 4.0L diesel which has 700 lbs/ft torque. It should be able to tow a braked caravan or trailer that weighs up to 3500kg comfortably.

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