>The manufacturing process and design was entirely different though. I used to work in automotive assembly, specifically in body panel stamping as a controls engineer (ie programming the robots). The big presses were set to accept both aluminum and steel. For example, the robots could use magnets for the steel or suction for the aluminum to move the parts, but the basic manufacturing used the same assembly lines. It was common to run both in the same shift.
