Ford Motor Company (NYSE:F) 's chief executive has estimated that manufacturing electric vehicles (EVs) will require 40% fewer workers than building gasoline-powered cars and trucks. As a result, the car maker will need to produce more parts in-house so "everyone has a role" in the transition, Jim Farley said. He warned of "thunderclouds" in the next phase of the EV transition, with Ford having a goal of achieving half of global sales from EVs by 2030. "It takes 40% less labour to make an electric car, so ... we need to insource so everyone has a part to play in that growth," Farley said at a conference in Detroit focused on improving racial diversity in the auto industry. "We need to embrace a whole new supply chain, in batteries, motors and electronics, and diversity needs to play an even bigger role in that," Farley commented.
