Migration from MHEV towards higher integrated solutions andHEV on lower voltage to achieve future CO2 and Emission Regulatory. (EU/CN)

Discussion on City Access Zones and especially the precise definition is seen as a decisive factor for BEV and/or PHEV.

Dedicated Hybrid Transmissions get more into the focus due to higher volumes.

BEV Cell prices are seen move further down (today: 145 USD/kWh GM Volt Gen2) and to further increase the energy density.
