Method for determining an expected consumption value of a motor vehicle for a predetermined driving situation, involving the steps of: a) Detecting respective actual consumption values upon each occurrence of the predetermined driving situation, by means of the motor vehicle's sensors, and storing these values, by means of the motor vehicle's memory unit, wherein the predetermined driving situation is characterised on the basis of a travelling speed and/or a type of road travelled and/or a gradient of the road travelled and/or a traffic situation, wherein these values characterising the driving situation are determined using the sensors, b) Checking, by means of the motor vehicle's control device, on the basis of the stored consumption values, whether there is a statistically significant data basis for the predetermined driving situation, for estimating consumption, while determining, on the basis of a number of stored consumption values, whether the stored actual consumption values satisfy a predetermined significance criterion, b1) if this is the case, determining, by means of the motor vehicle's control device, the expected consumption value, on the basis of the stored consumption values, and determining the range of the motor vehicle, by means of the motor vehicle's control device, using the expected consumption value, b2) if this is not the case, determining, by means of the motor vehicle's control device, an estimated value for the expected consumption and determining the range of the motor vehicle, by means of the motor vehicle's control device, using the estimated value, wherein the estimated value is determined on the basis of measured consumption values for at least one other motor vehicle of the same type and with the same engine for the predetermined driving situation, which are obtained by means of the motor vehicle's wireless communication with a computing device, or wherein the estimated value is determined on the basis of the motor vehicle's stored consumption values, which are transmitted wirelessly at predetermined intervals to the computing device, for another driving situation, which is comparable with the predetermined driving situation, in terms of consumption, wherein the other driving situation is selected from all driving situations on the basis of a cluster analysis such that at least one distribution measure of the stored consumption values of the other driving situation corresponds with the respective distribution measure of the stored consumption values for the predetermined driving situation within the framework of a predetermined proximity measure. a) Detecting respective actual consumption values upon each occurrence of the predetermined driving situation, by means of the motor vehicle's sensors, and storing these values, by means of the motor vehicle's memory unit, wherein the predetermined driving situation is characterised on the basis of a travelling speed and/or a type of road travelled and/or a gradient of the road travelled and/or a traffic situation, wherein these values characterising the driving situation are determined using the sensors, b) Checking, by means of the motor vehicle's control device, on the basis of the stored consumption values, whether there is a statistically significant data basis for the predetermined driving situation, for estimating consumption, while determining, on the basis of a number of stored consumption values, whether the stored actual consumption values satisfy a predetermined significance criterion, b1) if this is the case, determining, by means of the motor vehicle's control device, the expected consumption value, on the basis of the stored consumption values, and determining the range of the motor vehicle, by means of the motor vehicle's control device, using the expected consumption value, b2) if this is not the case, determining, by means of the motor vehicle's control device, an estimated value for the expected consumption and determining the range of the motor vehicle, by means of the motor vehicle's control device, using the estimated value, b1) if this is the case, determining, by means of the motor vehicle's control device, the expected consumption value, on the basis of the stored consumption values, and determining the range of the motor vehicle, by means of the motor vehicle's control device, using the expected consumption value, b2) if this is not the case, determining, by means of the motor vehicle's control device, an estimated value for the expected consumption and determining the range of the motor vehicle, by means of the motor vehicle's control device, using the estimated value,
