Aluminum is high cost. Tooling is different. All chromed working surfaces. Shallow draw. Lots of air release holes. The process is slower and QC is the highest. I can see hood, doors and roof panel but question the rest. Maybe front fenders if the design isn't to complicated. GM is not a leader in this field, so I see some outside contractors doing a lot of the initial work here. This is absolutely nothing like drawing DQSK steel. Not even close. I would recommend to GM to NOT use people from a steel stamping facility to make any aluminum parts. Major mistake. Requires muti-speed transfer presses. FYI the thickest metal used to make any body part was the late 80s Camaro Firebird T top, convertible rear quarters. .040 steel
