The EU funded project “Powerful” supported the creation of new solutions to reduce fuel consumption and emission levels below current levels. The task of the related project, performed with a Golf 6 Variant TDIDI® BMT, is the achievement of 98 g CO2/km in NEDC under respect of EU6 minus 10% emission limits. This article describes the general activities undertaken regarding the overall technical approach, the efforts of developing the research engine, it´s integration into a special validator vehicle and the main results. Some technical features like LTC (Low Temperature Combustion) or heat storage system of engine and vehicle are described more detailed. Beside the NEDC also more dynamic cycles have been investigated including real world driving.
