GM to build Chevrolet Silverado electric pickups at Factory Zero in Detroit

General Motors Co said on Tuesday its first electric vehicle assembly plant at Detroit-Hamtramck, Michigan, will make a Silverado electric pickup truck under Chevrolet brand.

The U.S. automaker did not say when its production will begin. GM had recently unveiled GMC Hummer electric sport utility vehicle, which will also be built at the plant, also known as Factory Zero. The company's plan is part of increased projected spending of between $9 billion and $10 billion this year, including more than $7 billion for electric as well as autonomous vehicles.
