An electric drive system (700) for a vehicle comprises a combustion engine (710) for providing a primary energy source for the vehicle; an energy storage unit (760) operably coupled to the combustion engine (710) for providing additional power for the vehicle; and an engine management system for monitoring an operational mode of the combustion engine (710). The engine management system is also operably coupled to the energy storage unit (760) and arranged to provide the additional power from the energy storage unit (760) for the vehicle intermittently, to substantially avoid emissions in a non-stoichiometric operational region of the combustion engine (710). In this manner, an electric drive system is described that optimises a combustion engine solely to produce emissions within acceptable limits. |
