Mercedes-Benz GLC updates and facelifts

Blue Mercedes-Benz GLC from the side

Available in a variety of diesel, petrol or hybrid engines, a used Mercedes-Benz GLC offers drivers a spacious, powerful and comfortable driving experience. Rival premium SUVs include the BMW X3, Jaguar F-Pace and Audi Q5, which the GLC competes comfortably with.

In 2016, the 43 trim was added to the line-up, giving the GLC a sportier look and performance. The GLC received a facelift in 2020, offering drivers the choice of two new efficient hybrid engines. Mercedes-Benz also tweaked the interior design, including more technology and increasing the boot size by 70 litres.

A used Mercedes-Benz GLC is also available in many different trims, offering unique features and body kits to enhance the look of the model.

Practicality and style of the car

As a large luxury SUV, the Mercedes-Benz GLC offers plenty of boot space. With a capacity of 550 litres, expanding to 724 litres by folding down the rear seats, this opens up a large flat space to transport bulky items. The boot also has a low lip and flat floor, which makes it easy to load and unload luggage.

The boot space does vary depending on which trim and generation of Mercedes-Benz GLC you opt for. A Mercedes-Benz GLC with a hybrid engine has a reduced boot space due to the battery being located in the boot.

The GLC confidently tows small trailers for transporting larger items. With a petrol engine, the GLC has a maximum braked weight of 2,000kg. This increases with a diesel engine to 2,500kg. Both engines also have an unbraked weight capacity of 750kg.

Running costs

As a luxury SUV, a used Mercedes-Benz GLC falls into insurance groups 40 to 50, with road tax being between £560-£570. This matches other luxury SUVs on the market. However, you can expect good returns on mpg from the range of engines available, which will help keep running costs down.
