Summary

Based on the requirement for ongoing CO2 emission reduction, the concept of gasoline engine downsizing is progressing also into the C-car and even B-car segment. The additional combination with downspeeding yields further CO2 emission reductions. As a consequence, engine size and displacement are considerably reduced, resulting in disadvantages for vehicle handling by customers in the areas of vehicle launch, gear shifting requirement, transient acceleration and gradeability. A successful downsizing concept therefore requires an integrated powertrain approach in order to reach solutions for the described deficiencies at affordable cost.
