Volvo Cars said it will only make and sell all-electric vehicles by 2030, as part of a broader transformation of the automaker that will include shifting sales online. “The key to sustainability is electrification, said Volvo Cars CEO Håkan Samuelsson during a presentation Tuesday. “Together with investments in charging infrastructure that is the right way to go and the course we have chosen at Volvo.” The announcement was tied to the launch of the C40 Recharge, a low slung crossover based on the company’s CMA vehicle platform.
