Abstract
A method of controlling a motor vehicle having a turbocharged engine is disclosed in which deactivation of cylinders of the engine is controlled to prevent the rotational speed of a turbocharger of the engine falling below a predefined limit TA, TB. Following commencement of a coast down of the motor vehicle all cylinders of the engine are first deactivated so as to maximise energy recuperation from the motor vehicle by a belt integrated starter generator driveably connected to the engine. However, if the speed of the turbocharger reaches one of the speed limits TA, TB at least one cylinder of the engine is reactivated to keep the turbocharger spinning.
