Mercedes GLC SUV - MPG, running costs & CO2
The Mercedes GLC is actually quite economical given its size
Mercedes GLC MPG & CO2
The 220 d version of the 2.0-litre diesel engine can return up to 45.6mpg, reducing slightly in top trims with optional wheels fitted. CO2 emissions of 175g/km mean it sits in the highest BiK band, which won’t appeal to company-car drivers. The more powerful GLC 300d is a shade less economical, at up to 42.8mpg, with emissions of 184g/km. By comparison, the BMW X3 xDrive 30d offers more pace and returns 46.3mpg with 159g/km.
Petrol engines are offered too. A GLC 300 model promises up to 33.6mpg, while the AMG 43 and 63 models above are even thirstier. They certainly prioritise speed over running costs; you can expect 26 and 22mpg respectively. All petrols are in the top BiK band.
A plug-in hybrid GLC 300 de version is now available, pairing the 2.0-litre diesel engine with a 13.5kWh battery. It offers 27 miles of electric range and up to 156.9mpg if you regularly recharge the battery, while business users will be drawn to its 12-13% BiK rate. It’s also exempt from the London Congestion Charge until October 2021. In 2021 it was joined by the GLC 300 e, with a petrol 2.0-litre engine and an electric range of 26-31 miles. It can officially manage up to 128.4mpg with emissions of 62g/km and it takes around 2.5 hours to charge the battery using a 7kW home wallbox.
After the first year's CO2-based road tax (generally included in the on-the-road price), Mercedes GLCs cost £150 a year to tax, or £10 less if it's a hybrid. Every GLC now has a list price (including options) of more than £40,000, making it liable for an additional surcharge of £325 a year in years two to six, bringing the annual bill to £475 during that period.
Insurance groups for the facelifted Mercedes GLC are quite high, with diesel versions starting in groups 32 and the GLC 300 de in groups 44-45 out of 50. Oddly, this is just as high as the AMG versions in groups 41-44.
Mercedes provides a three-year/unlimited-mileage warranty on all of its new models, which is the same as BMW offers on the X3. Pan-European Mercedes Roadside Assistance is also included, that can last up to 30 years if you keep the car maintained within the dealership network.
Mercedes offers fixed-price servicing plans that cover all scheduled maintenance. You can pay all in one go up front or spread the cost over monthly instalments, which should be about £35 for a diesel GLC.
