Volkswagen Group of America on Tuesday announced a U.S. subsidiary that will manage $2 billion in investments in zero emission vehicle infrastructure and awareness programs over a decade as part of a court settlement over its excess diesel emissions. The world's largest automaker by sales said the unit plans to install more than 500 charging stations nationwide, including more than 300 stations in 15 metro areas, and to develop a high-speed, cross-country network consisting of more than 200 stations. VW will also launch a "Green City" initiative in a yet-to-be-identified California city to pilot future concepts, including potentially a ZEV-based shuttle service, an EV-based car-sharing program, or a ZEV transit program.
