Tesla’s C.E.O. has a long history of promising products that materialize later than he said they would or not at all, but his timeline for the Cybertruck is more definite than the one he gave to investors in January, when he said that delivery in 2023 was “most likely.”
Delays in producing the Cybertruck have allowed rivals to come to market sooner with pickups, one of the most popular types of vehicle in the United States. Ford is expected to begin delivering the Lightning, a battery-powered version of its F-150, this summer. Rivian’s electric pickup went on sale late last year to rave reviews, but the company has had trouble ramping up production, a common problem for new car companies.
Tesla invited about 15,000 people to the Cyber Rodeo, which Mr. Musk, with his customary hyperbole, billed as the “biggest party on earth.” The factory is as large as three Pentagons, he said.
Local schools closed early so that parents could avoid traffic jams caused by those flocking to the event, the television station KXAN reported. The actor Harrison Ford was among the guests. Tesla parked red, white and blue cars in formation to look like the Texas state flag.
The factory is part of a global expansion by Tesla that includes a newly opened plant near Berlin. Along with an existing factory in Shanghai, the new assembly lines could help the company repeat its growth in 2021, when it nearly doubled sales to almost one million vehicles, far outpacing other major carmakers.
