Lucid Group is upping its game at its Casa Grande EV auto plant. The company is set to spend $1 billion on Phase II of its Advanced Manufacturing Plant. Lucid will be making its Gravity SUV at the plant and with the extra space hopes to increase its production to 90,000 vehicles a year.

It marks one of the most significant and largest investments in vehicle manufacturing in the state, alongside other automotive startup companies such as Nikola Corp. and ElectroMechanica, who recently announced they were merging with Tevva.

The company has previously said that at full build-out, its campus could total 15 million square feet across 2,000 acres — or the size of an original equipment manufacturer hub that could also house suppliers and 6,000 employees.
