Summary

Significant reduction of the fuel consumption respectively CO₂ emission is the most relevant driver of the worldwide passenger car power train development. The electrification of the powertrain is a prerequisite to achieve future fuel comsumption targets, while the internal combustion engine will remain a key component of all high volume powertrain systems. The challenge for the engine development is further increase of efficiency at increasing cost pressure. The trend to turbocharging and direct injection for all engine configurations as well as unpredictable volume splits of combustion concepts and the demand for flexible localisation lead to the requirement of engine family architectures with common partsand machining concepts for future gasoline and diesel engine families.
