At the very end of September, CEO Elon Musk personally delivered the first handful of Tesla Model X electric crossover utility vehicles to their buyers in an event at its assembly plant.

Since then, Tesla's plant in Fremont, California, has been building increasing numbers of the Model X alongside the existing Model S sedan.

The factory is likely now in the process of ramping up production of the Model X, which had been delayed multiple times by development issues.

And if you were wondering what the Tesla assembly line looks like during the process of building a Model X, this video from The Car Guide offers a quick glimpse.

The video shows aluminum sheets being stamped into body components and robots maneuvering parts into place to be welded.

Then a completed body is lifted skyward, and sent to the paint shop on a conveyor system built into the factory's "attic."

The Model X line features 458 robots--three times as many as the Model S line, according to The Car Guide.

Tesla says the plant is currently running at the rate of 1,000 electric cars per week, but it has the capacity to build more.

What is now Tesla's factory was once New United Motor Manufacturing,Inc. (NUMMI), a collaboration between General Motors and Toyota.

At peak production, it built about 500,000 cars per year--mostly compacts like the Geo Prizm and Pontiac Vibe.

After launching Model S production in 2012, Tesla briefly halted production in 2014 to add capacity for greater production volumes across more model lines.

The retooling included additional automation and other efficiency-related improvements.

So Tesla has the capacity to produce significantly more cars than it does now, although for the time being the Model S will likely account for the bulk of production.

While Tesla CEO Elon Musk previously said the Model X production ramp will be much quicker than that of the Model S, he also said it wouldn't begin in earnest until early in 2016.

The six Model X crossovers delivered at a flashy public event at the Fremont factory were probably expedited so that Tesla could claim it had delivered the car during the third quarter, as promised.

Two of the those first vehicles went to Musk and Tesla boardmember Steve Jurvetson.

It wasn't until last month that Tesla began letting Model X depositors specify all Model X variants; it had previously opened final specifications only for the initial run of special P90D Signature Series models.

Tesla claims it will deliver "50,000 to 55,000" vehicles in 2015, slightly down from a previous estimate of simply 55,000. Its final 2015 delivery total will be reported early next month.
