- 4. 4Qualcomm Technologies, Inc. The Future is Electric and Wireless We will be electrifying all Mercedes-Benz model series. Daimler AG, Member of the Board of Management, Thomas Weber We strive to electrify two-thirds of global automobile unit sales in 2030. Honda President & CEO, Takahiro Hachigo By 2025, the BMW Group expects electrified vehicles to account for between 15-25% of sales. BMW brand By 2025, we want to sell a million electric cars per year and to be the world market leader in e-mobility. Volkswagen brand ...global offerings of electrified vehicles will exceed gasoline-powered vehicles within the next 15 years. Ford President and CEO, Mark Fields …Volvo Cars has stated that it plans to have sold a total of one million electrified cars by 2025. When we said it, we meant it. Volvo CEO, Håkan Samuelsson The trend to go electric is already irreversible. But where is the next growth area? There’s no doubt that it will be in consumer vehicles, most of them plug-in hybrid models. BYD Chairman and President, Wang Chuanfu
