ABSTRACT - Environmental concern demands that emissions and fuel consumption of cars have to improve considerably before 2010. New technologies for gasoline engines, downsizing with high boosting, direct injection and fully variable valve train systems are being developed. For diesel engines, improved components including piezobased injectors, particle filters and DeNOX technologies are expected. Automated manual transmissions will contribute to this target. In parallel introduction of hybrids as integrated starter-generator with braking energy recovery is expected and compressed natural gas as alternative fuel is promoted. This paper reports the progress made in the recent years and gives a comparative assessment on the different technologies with a prediction of introduction dates and volumes into the market.
