The process of assembling automobiles hasn’t changed much since the concept was pioneered by Ford Motor Co. more than a century ago. But, engineers at Tesla Inc. have developed a new process that they claim will reduce EV production costs by 50 percent, while reducing factory space by 40 percent.

The “unboxed” system was outlined during the automaker’s recent Investor Day event at its new factory in Austin, TX. Tesla believes that its more efficient production method will lead to a paradigm shift in the way that vehicles are mass-produced. It focuses on eliminating linear assembly lines and producing more subassemblies out of large castings.
