SAN FRANCISCO -- Elon Musk has six days to make good on his pledge that Tesla Inc. will be pumping out 5,000 Model 3 sedans a week by the end of the month. If he succeeds, it may be thanks to the curious structure outside the company's factory. It's a tent the size of two football fields that Musk calls "pretty sweet" and that manufacturing experts deride as, basically, nuts.
"Words fail me. It's insanity," said Sanford C. Bernstein & Co.'s Max Warburton, who benchmarked auto assembly plants around the world before becoming a financial analyst.
Inside the tent in Fremont, Calif., is an assembly line Musk hastily pulled together for the Model 3. That's the electric car that is supposed to vault Tesla from niche player for the wealthy to high-volume automaker, bringing a more affordable electric vehicle to the masses.
Tesla has had a heck of a time making the leap. Musk's expectation two years ago was that 100,000 to 200,000 Model 3s would be produced in the second half of 2017. Just 9,766 rolled out in the first quarter -- a weekly output rate of roughly 750.
Hence, apparently, the tent. Musk announced it on Twitter on June 16, saying the company had put together an "entire new general assembly line" in three weeks with spare parts; the building permit was issued on June 13, though the company could have started working on aspects of the project before that.
Whether this new line is fully operational is unclear. Company officials declined to comment. The Tesla-obsessed users of Twitter and other Internet forums have posted photos and videos and comments either praising or ridiculing the parking lot big top. Apparently in response to the intense interest, the tent has recently been surrounded by very large trucks, which obstruct the view.
When Tesla releases second-quarter production and delivery figures in early July, the hundreds of thousands of customers who've been waiting since March 2016 for their Model 3s, having put down $1,000 deposits, will get a better sense of how much longer they'll be in the queue. "The question is, how much rope Musk will get from customers who have had to wait years for delivery?" said Jeff Liker, a University of Michigan engineering professor who has written books on Toyota Motor Corp.'s vaunted production system.
What gives manufacturing experts pause about Tesla's tent is that it was pitched to shelter an assembly line cobbled together with scraps lying around the brick-and-mortar plant. It smacks of a Hail Mary move after months of stopping and starting production to make on-the-fly fixes to automated equipment, which Musk himself has said was a mistake.
"The existing line isn't functional, it can't build cars as planned and there isn't room to get people into work stations to replace the non-functioning robots," Warburton wrote in an email. "So here we have it -- build cars manually in the parking lot."
An admission in April that he erred by putting too many robots in Tesla's plants was a humbling moment for Musk. The CEO had boasted that his company would build an "alien dreadnought," sci-fi bro code for a factory so advanced and robotic, it would be incomprehensible to primitive earthlings.
During a February earnings call, Musk told analysts that Tesla had an automated-parts conveyance system that was "probably the most sophisticated in the world." But by spring, it had been ripped out of the factory.
"We had this crazy, complex network of conveyor belts," Musk told "CBS This Morning" in April. "And it was not working, so we got rid of that whole thing."
