… in China only 1 % of cars have a diesel engine and there is a preference for more spacious vehicles which naturally are heavier. The answer to this challenge can only be a holistic approach. We have to think in terms of all possible technical solutions, including sophisticated vehicle and powertrain measures as well as alternative drive systems.

… On the subject of plug-in hybrid as a focus of the Volkswagen Group for developing new-energy vehicles in China, I think we should be aware that plug-in hybrid power is the best solution in the short and medium term. Perhaps the development of all-electric vehicles can be realized in the long run. Discussions are ongoing in this respect also with Chinese experts. We need to find solutions to facilitate the development of highly efficient batteries. And at component level we need to consider how to further improve energy conservation in both conventionally powered and electric models.

There is also an accompanying need to establish an electric vehicle fast charging standard in China, Dr. Heizmann said, noting that while plug-in hybrids can be charged overnight at ordinary household sockets, battery-electric vehicles will benefit from a fast-charging infrastructure.

Currently, for example, you cannot drive an all-electric vehicle from Beijing to Shanghai and rely on charging along the way. This is because the infrastructure has not been completed yet – and even once it is, the standard may not be universal. To this end, we need dependable, stable technologies. This way, in the future we can channel our development investments in the right direction and contribute towards advancing plug-in hybrid technologies.

Although the biggest challenge confronting Volkswagen with respect to electric vehicles is cost, Dr Heizmann wrote, the Group expects future electric vehicles to achieve the same price levels as conventional models.
