Mercedes GLC hybrid range, MPG, CO2 & charging
The GLC hybrid is available in petrol or diesel form; both promise around 30 miles of electric range
| Fuel economy | CO2 emissions | Electric range | Wallbox charge time |
|---|---|---|---|
| 123-157mpg | 47-52g/km | 26-29 miles | 1hr 30mins (10-100%, 7.4kW) |
There are other Mercedes models available as either diesel or petrol plug-in hybrids – for example, the C-Class and E-Class saloons. However, a diesel-electric SUV is still a rare thing and none of the car’s main rivals from BMW, Audi and Volvo offer this option.
Diesel works best for fuel economy on longer trips, as these engines are efficient at a constant speed on the motorway. The petrol version should be nearly as economical if you mainly use electric power, but it’s not as good for long-distance excursions.
Mercedes GLC hybrid SUV range, MPG & CO2 emissions
As you might expect, the diesel-electric GLC 300 de is the more efficient of the two versions, with claimed fuel economy topping out at 157mpg (versus 123mpg for the petrol) and CO2 emissions as low as 47g/km (versus 52g/km for the petrol).
That last figure is important, as it means the GLC 300 de is in a lower company-car Benefit-in-Kind (BiK) tax band than the GLC 300 e (12% versus 13% during the 2021/22 tax year). That could be the clincher for many, although certain versions of the petrol are actually in the same bracket as the diesels due to slight changes in specification. The electric range for both versions is under 30 miles – 26-27 for the diesel version and 29 for the petrol.
Charge time
Mercedes says the GLC 300 hybrid's on-board charger allows for a top-up from a standard home wallbox in 90 minutes for both models. Charging from a domestic socket using a three-pin plug will be much slower – about five hours. That’s still easy for overnight charging, though.
