How much does the Mercedes Benz GLC cost to run?

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

The Mercedes Benz GLC 2.1L diesel costs £145.00 a year to tax, as it sits in tax band E.

It does not far off 57 MPG on average, which means it will cost £11.00* in diesel every 100 miles driven.

In terms of fuel efficiency, it sits between the Suzuki Vitara 1.6L diesel and the more thirsty Mazda CX-5 2.2L diesel.

The lower the insurance group, the cheaper a car should be to insure. This model is rated insurance group 29, which is lower than the Land Rover Freelander 2.2L diesel, but higher than the Honda CR-V 2.2L diesel. (If insurance cost is important to you then the Suzuki Vitara has the lowest insurance group.)

Mercedes Benz GLC: How big is the boot?

The Mercedes Benz GLC SUV has a bigger boot than the coupe (it can hold 550 litres of luggage with the seats up).

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

Worth knowing, the Land Rover Discovery Sport SUV is the best in class, allowing for one pushchair and 7 large bags with its 981 litres.

Is the Mercedes Benz GLC easy to park?

This is one of the widest cars in the class, which makes it feel like a bit of a squeeze in the multi-stories. If that stresses you a bit, try the much narrower Suzuki Jimny.

When it comes to parking on the street, the GLC is one of the hardest. It has a turning circle of 12m, and a length of 4685m, giving you a relatively small 115mm gap to turn the car in and out.

If you don’t have a drive, you should look at the best in class for parallel parking instead, the Suzuki Jimny.

Which Mercedes Benz GLC has the best performance?

The fastest Mercedes Benz GLC from 0-60, is the 3.0L diesel (if you’re a petrol head, it has 620 lbs/ft torque and 258 bhp). It hits 60 mph in 6.2 seconds.

The closest rival in its class is the BMW X3 3.0L diesel, which will beat your Mercedes Benz GLC to 60 by 0.3 seconds. That doesn’t sound much, but in 0-60 terms it’s actually a big gap.

What size caravan or trailer, can the Mercedes Benz GLC 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 GLC 3.0L diesel which has 620 lbs/ft torque. It should be able to tow a braked caravan or trailer that weighs up to 2500kg comfortably.

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