vehicles sold contain
electrified powertrain.
Current EU & China
stimulus programs
focused on xEV.
China continues to
be major market
driver for xEVs.
EU drives complete
fleet electrification
leading in HEV/PHEV.
Tesla stays strong;
US Big-3 increase
xEV focus.

“As part of the first wave of Volkswagen’s battery electric vehicle initiative we’ll deliver up to 75 full-
electrical vehicle models to market by 20291,” said Dr. Holger Manz, Head of Development for
Vehicle Energy Supply and High Voltage Systems, Volkswagen AG. “Incorporating a functionally
safe battery management system that can scale across many car models makes it easier to
achieve the full power potential of a battery, optimized range and the extension of the battery’s
lifetime.”
