Summary

In recent years, the main driver for powertrain innovations was primarily the reduction of fuel consumption and the associated more stringent CO2 emission requirements. Depending on different vehicle market segments and engine categories, fuel consumption and CO2 emission targets varies. In addition to engine improvements, various electrification and alternative transmission concepts are discussed thoroughly. Meanwhile, mass production solutions have successfully entered into the market. This paper provides an overview of the state-of-the-art technologies in the engine, transmission and electrification fields and helps to establish the synergy among them. Through simulation-based evaluations, potential paths to achieve the target fuel consumption and driveability performance are defined...
