A method is disclosed for determining a driving range for a motor vehicle. Initially, extra-vehicle data are received, whereby the extra-vehicle data include at least one weather parameter value. A vehicle-dependent parameter value, which depends on the extra-vehicle data, is determined. The driving range for the motor vehicle, which depends on the vehicle-dependent parameter value, is determined. Also disclosed is a motor vehicle that is configured to receive extra-vehicle data, including at least one weather parameter value. The motor vehicle is configured to determine a vehicle-dependent parameter value from the extra-vehicle data. The motor vehicle is configured to determine a driving range from the vehicle-dependent parameter value. In the method and motor vehicle embodiments, the extra-vehicle data are obtained from at least one additional motor vehicle.
