The Automotive Manufacturers Association (ACEA) has agreed to target a fleet average fuel consumption of 140 g/km CO2 throughout Europe for the year 2008. A current, typical OEM average vehicle fleet produces approximately 185 g/km CO2 (compiled from published data). Therefore, the introduction of popular vehicles with significantly less fuel consumption than is currently achieved will be required. The Ricardo Integrated Research Programme (IRP), in collaboration with Valeo, is integrating these systems into a 'C' class vehicle. This offers Ricardo the ability to demonstrate the powertrain capabilities, validate modelling tools and to develop innovative solutions required for such systems. More importantly, this is an opportunity to assess the cost / benefit ratio for such technologies in order to give realistic advice for future OEMs and Tier 1 suppliers product planning. Achieving improved fuel consumption and emissions legislation beyond Euro IV will involve increasing use of new powertrain technologies if customer requirements for performance, cost and reliability are to be retained. Ricardo is investigating these technologies in collaboration with Valeo via the physical application of mild hybrid systems to a highly down sized HSDI diesel engine within the popular 'C' class vehicle sector. This research programme aims to demonstrate less than 4 litres per 100 km fuel consumption, half of the current Euro IV emissions levels and strong vehicle perforrnance whilst assessing the cost / benefit ratio of each new technology. This can only be achieved through the integration of both the hardware and the control of such powertrain systems. Within this paper the practical approach Ricardo has taken is outlined together with the results attained so far.
