While Tesla’s preoccupation with product secrecy is nowhere near as obsessive as Apple’s, the company over the past few years has become a bit more guarded about the happenings at its Fremont factory.

Over the past few months, however, Tesla has seemingly become a bit more willing to pull back the curtain of secrecy ever so slightly. This past February, for instance, Tesla allowed – for the first time in 5 years – a news crew to visit the factory where it manufactures the Model S and the Model X. Naturally, the crew managed to capture never before seen footage of Tesla’s Model X production line.

More recently, Tesla allowed what appears to be a German site that predominantly tests iPhone and iPad accessories into its Fremont factory where they managed to film never before seen footage of the Model X manufacturing process. Featuring compelling footage of the Model X assembly line, bolstered of course by Tesla’s army of futuristic and advanced robots, the video provides a fascinating look into the advanced processes that comprise Tesla’s intricate production process.

But perhaps the coolest part of the video is when we’re given a quick peek at how Tesla manages to attach battery packs to cars on the production line. As the video below demonstrates, Tesla relies upon automated guided vehicles to transport the batteries across the factory floor. From there, the battery is pushed up to the floor of the waiting car.

For anyone with even a passing interest in Tesla, the video is chock-full of interesting information. Note that the video is in German, so make sure that closed captioning is toggled on.
