I've been speculating recently on this forum that Lucid has received a guarantee from the Saudi PIF for continued funding. In my view, the four-fold expansion of manufacturing capacity in Case Grande and Rawlinson's recent stepping out of the closet to declare publicly that Lucid is going to compete directly with Tesla Models 3 and Y could only be explained in light of such a guarantee.
The Saudis have a goal to be making 500,000 EVs a year by 2030. This would not be possible unless the engineering and design efforts were already well along . . . and this is where Lucid comes into view with the Saudi decision in 2018 to get it off the ground by financing their first factory.
