Tesla’s Production Efficiency: The Next Moving Assembly Line

Henry Ford revolutionized the transportation industry when he introduced the moving assembly line into his factories. It wasn’t the introduction of a new car, but the increase in production efficiency that changed the industry dynamics. It seems unimaginable that vehicle production efficiency has barely improved in the last 100 years. Because of the stasis in production efficiency, ARK took note during Tesla’s TSLA second quarter earnings call when Elon Musk said that he expects a step-function improvement in Tesla’s production efficiency.1

When Ford introduced the moving assembly line, production efficiency increased by roughly an order of magnitude. As shown below, Ford’s innovation left the rest of industry in the dust, and is arguably the tipping point that led to tremendous consolidation in the auto industry. While the moving assembly line is innovative, with few barriers to entry the rest of the auto industry was able to adopt the technology.

By 1929, the auto industry had experienced a major shakeout and its productivity seemed to be hitting a ceiling. As shown below, vehicles produced per worker have increased very little since 1929. Vehicles produced per production employee have increased less than 0.4% compounded annually over the 85 years of data.2 While vehicles produced today are higher in quality, the process of transporting a person from point to point has not changed.

Tesla is not the first auto manufacturer to aim for an improvement in productivity. Toyota TM has its “New Global Architecture,”3 BMW BMW.DE its “Value-Added Production System,”4 and Faraday Future its “Variable Platform Architecture.”5 Yet, as we see it, most efficiency-driven programs today are focused on less customization and more modularity.

In contrast, we think Tesla’s approach could cause a step-function increase in productivity. Currently Tesla’s productivity is low relative to the competition, as shown below, but the comparison is not life-for-like. Based on our analysis, Tesla is more vertically integrated than the other manufacturers. Instead of simply assembling out-sourced parts in a plant, it is turning raw materials into cars, much like Ford did in its plants in 1914.

While automotive manufacturing has the highest industrial robot density of any industry,6 Tesla is unique in the industry as robotics has become part of its vertical integration. Traditional auto manufacturers in our opinion are constrained during production by the quality and timing of parts received from suppliers. A fully automated factory, building vehicles from scratch, can optimize the process based on first principles, Musk’s preferred method of operation.7

ARK believes that if Tesla realizes a step-function increase in productivity that it anticipates at its Fremont factory, its production could approach one million units, without an increase in the number of people it employs. Musk notes that employees will be “maintaining machines and upgrading the machines and dealing with anomalies. And the output per person will be extraordinarily high.” 8 We think robots will be key to the turbocharging of the productivity. As shown below, if Tesla realizes its goals, Fremont’s productivity would increase roughly ten-fold, topping the most productive auto manufacturing plans in place today by nearly three-fold.

  7. After the Gigafactory tour, Electrek noted that while the Fremont factory had mainly Kuka robots, the Gigafactory had mainly Fanuc robots. In this regard, it has been reported Fanuc has taken a small stake in an artificial intelligence company, Preferred Networks, and has demonstrated the ability to connect robots and have them teach each other how to accomplish a task. While other auto manufacturing plants have not changed for decades, Tesla has been populating its factories with robots that should be able to learn and improve over time.

I disagree that Ford’s efficiency increase was due to the moving assembly line. I believe what set Ford apart from others was that Ford abandoned stone age design – manufacturing with non-interchangeable parts. Ford discusses this in his book “My Life and Work.” “The parts of a specific model are not only interchangeable with all other cars of that model, but they are interchangeable with similar parts on all the cars we have turned out.” “My Life and Work”, Henry Ford in collaboration with Samuel Crowther, Doubleday, Page and Company, Garden City, New York, 1923 This method of production was… Read more »
