Method and device for controlling a motor vehicle with optimised consumption

The invention relates to a method for consumption-optimized control of a motor vehicle, in which it is checked according to the invention whether a predetermined optimal operating mode (B1) for controlling the motor vehicle is activated and a limit value (G) for average fuel consumption and/or a limit value (G1) for gas emission is specified, wherein, when the optimal operating mode (B1) is activated and a limit value (G) for average fuel consumption and/or a limit value (G1) for gas emission is determined, the motor vehicle is controlled such that at most the specified, in particular a minimal limit value (G) for average fuel consumption and/or a minimal limit value (G1) for gas emission is consumed.
