Fuel economy is a key aspect to reduce operating costs and improve efficiency of freight traffic, thus increasing truck competitiveness. Under the coordination of AVL List GmbH, the main objective of the IMPERIUM project is to achieve fuel consumption reduction of up to 20% (diesel and urea) whilst keeping the vehicle within the legal limits for pollutant emissions. The IMPERIUM consortium, consisting of the major European actors, represents those responsible for manufacturing 45% of the heavy duty vehicles manufactured in the EU and is able to provide a 100% European value chain for the development of future powertrain control strategies for trucks.
