GM renames its Detroit-Hamtramck plant Factory Zero

The $2.2 billion investment to retool and upgrade the facility comes just days before it is set to unveil the HUMMER EV, a fully electric truck.

GM said that the Hummer EV pickup will start production at the facility in late 2021, keeping closely to the fall 2021 timeline given by CEO Mary Barra previous year. GM officials confirmed in a follow-up Q&A with the press that the GMC Hummer SUT pickup would precede the GMC Hummer SUV by a a short time, as part of a normal production ramp-up.

Check back with Autoblog when the Hummer is revealed next Tuesday, Oct. 20. During construction, excess concrete from pours in the plant has been used to pave roads, and stormwater runoff is being recycled to charge the factory suppression system and circulate in cooling towers.

General Motors further boasts a wildlife habitat spanning over 16.5 acres within the site, "home to species like monarchs, foxes, and turkeys." .

GM says it's committed to powering all its southeast MI plants with sustainable energy by 2023, the rest of its USA facilities by 2030, and overseas plants by 2040. Factory ZERO is planned to switch to 100-percent renewably energy by 2023, and two of the sources for clean energy are the 30-kilowatt solar carport and a 516-kilowatt photovoltaic solar array.
