Tesla Inc's new vehicle-assembly system, which created instant buzz when it was unveiled in March, ignited a debate among auto manufacturing experts on whether CEO Elon Musk's so-called unboxed process is radical, revisionist or derivative - or all of the above.
When the new process was revealed at Tesla's March 1 Investor Day, executives said it would make the company's next-generation vehicles"significantly simpler and more affordable."
