At Backchannel, Teslaâ(TM)s former VP of production, Greg Reichow, pulls back the curtain on the factoryâ(TM)s âoesecretâ second floor, where many of Teslaâ(TM)s battery, power electronics, and drive-train systems are built. âoeIt was home to some of the most advanced manufacturing and automation systems in the company,â Reichow writes. Baffling to some, Reichow explains the importance of Teslaâ(TM)s vertical integration. Had the electric vehicle company simply spent too much time inhaling the âoewe know betterâ fumes of Silicon Valley? No, says Reichow. The former VP breaks down why taking on the madness of building their own car components was so worth while.
