Abstract
The invention relates to a method and a device for operating a motor vehicle with an internal combustion engine in a coasting operating mode in which the motor vehicle rolls essentially in a propulsionless fashion and essentially without a perceptible engine drag torque on an essentially level road if there is no propulsion request or braking request from a driver of the motor vehicle. According to the invention, the coasting operating mode is not brought about by automatically opening the drivetrain but rather is simulated with the clutch closed in that so much air/fuel mixture is fed to the internal combustion engine that the engine drag torque is largely but not completely compensated.
