Estimates, not measurements: the WLTP figure scaled by the same temperature and road factors for every car (for example 65% for cold motorway driving, 115% for mild city driving). Your range depends on speed, wheels, load and heating. For a planned stop, use the charging simulator.
Calculated from sustained 10-80% DC fast charging speed, cold-weather aerodynamic drag, and official WLTP range (455 km283 mi).
The official combined WLTP range for the Mercedes-Benz GLC 300 4MATIC is 455 km (283 miles).
In cold winter conditions (-5°C / 23°F) at highway cruising speeds (120-130 km/h), expect a realistic highway range of approximately 328 km (204 miles) due to cold battery chemistry, cabin heating, and higher aerodynamic drag.
Charging the 85 kWh battery from 0% to 100% takes approximately 7 hours using a standard 11 kW 3-phase AC wallbox. On a single-phase 7.4 kW home charger, a full charge takes around 10.3 hours (typically overnight).
The Mercedes-Benz GLC 300 4MATIC supports peak DC fast charging rates of up to 320 kW. Recharging from 10% to 80% State of Charge (SoC) requires approximately 15 minutes at a compatible ultra-rapid charging station.
At an average European residential electricity tariff of €0.24/kWh, a complete 0-100% home charge costs approximately €20.40. At high-power public DC charging networks (~€0.65/kWh), a full recharge costs approximately €55.25.
