Tesla, Inc. is a globally leading electric vehicle and clean energy company, headquartered in Austin, Texas, USA. The brand was founded by Martin Eberhard and Mark Tarpenning in July 2003 and named after inventor Nikola Tesla. In 2004, Elon Musk led the Series A financing round and joined the company, subsequently becoming Tesla's core leader and establishing the brand mission "to accelerate the world's transition to sustainable energy." Tesla is one of the earliest companies to achieve mass production and commercialization of battery electric passenger vehicles and is a core force driving the automotive electrification trend.
Tesla's business covers electric vehicle design and manufacturing, autonomous driving technology R&D, artificial intelligence, energy storage systems, solar power generation, and multiple other fields. As of early 2026, Tesla has built and operationalized six Gigafactories globally, with three more factories under construction. In 2025, Tesla experienced one of the most severe tests in its brand history: cumulative global vehicle deliveries reached 1.6361 million units, a year-on-year decrease of 8.6%, marking the second consecutive year of decline; total revenue was $94.827 billion, a year-on-year decrease of 2.93%, representing the first annual revenue decline; net attributable profit was $3.794 billion, plummeting 46.79% year-on-year. Tesla was also surpassed in 2025 by China's BYD, which sold 2.26 million pure electric vehicles, losing the title of global best-selling pure electric vehicle brand that it had held for many years.
Tesla's founding did not start with Musk. In 2003, after the original Roadster went through twists and turns, Tesla launched a pure electric sports car based on a modified Lotus Elise in 2008, achieving "0-100 km/h acceleration in 3.7 seconds." In 2010, Tesla took over General Motors and Toyota's old factories at the California Fremont Factory for renovation, introducing highly anticipated electric vehicle production technologies. In 2012, the Model S was launched, becoming the first electric vehicle with performance truly comparable to traditional luxury sports cars, establishing Tesla's milestone status in the high-end pure electric market.
Mass Market Path and Shanghai Gigafactory: To implement its corporate mission of "promoting sustainable transportation," Tesla released the Model 3 for the mass market in 2016. In 2017, the Model Y and Semi truck were released, with the Model Y becoming Tesla's fastest global sales volume leader. At the end of 2017, the Fremont Factory's production ramp-up lagged significantly, and Musk slept in the factory to solve the issues, causing temporary production panic, but Tesla ultimately passed the test. In 2019, the Shanghai Gigafactory was built and operationalized within just one year, becoming Tesla's first overseas manufacturing factory and greatly reducing the production cost and selling price of the Model 3 and Model Y. The production launch of the Shanghai factory was an important turning point for Tesla from near bankruptcy to continuous profitability. Subsequently, the Texas Austin and Berlin Gigafactories were put into production, and Tesla essentially completed its global factory layout.
FSD and Shift to an AI Enterprise: Musk vigorously promoted the pure vision autonomous driving route from 2019, abandoning the LiDAR technology scheme. Tesla fully self-developed the Dojo supercomputer to process massive autonomous driving data and gradually pushed the complete FSD Beta version to approximately 2 million users globally. In June 2025, Tesla launched the Robotaxi unmanned taxi service in Austin, marking the entry of FSD unsupervised mode into the commercial stage. In January 2026, Musk stated at the earnings conference that Tesla would transform from an electric vehicle company into a "physical world artificial intelligence and humanoid robot" company. In 2025, the Model Y and Tesla facelifted versions continuously won the status of best-selling models globally, but this also marked that Tesla had not introduced any new large-scale volume models in the past five years.
Tesla's product line is streamlined but clearly positioned, with core models remaining only four for a long time: the Model S, Model X, Model 3, and Model Y. The year 2025 was a year of major adjustment in Tesla's product structure: it announced the cessation of Model S and Model X production at the end of Q2 2026, and the Fremont Factory will be renovated into an Optimus humanoid robot factory, with an annual production capacity target of 1 million units.
The Model 3 and Model Y are Tesla's main sales pillars. In 2025, the Model 3 and Model Y series underwent comprehensive redesigns. The Model Y is Tesla's single model with the highest global sales, holding the annual sales champion title in markets such as Norway and Australia. The Model Y Long Range Rear-Wheel Drive version and 7-seater L version completed production ramp-up at the end of 2025.
The Cybertruck is Tesla's electric pickup, which began deliveries in Q4 2023. This highly futuristic stainless steel electric pickup was Tesla's star model aimed at disrupting the pickup market, but sales slumped quickly after its launch. In 2025, Cybertruck cumulative delivery volume was only about 17,012 units, far short of Musk's previously predicted 2025 annual production target of 250,000 units. Compared to the estimated 50,000 units in 2024, the decline is even more startling; some statistics show that Cybertruck sales in the US in 2025 were only 20,237 units, a drop of over 48% compared to 2024. The Cybertruck was squeezed out of the mainstream US electric pickup competition, with the Ford F-150 Lightning's quarterly sales exceeding those of the Cybertruck during the same period.
The Semi Truck is Tesla's Class 8 electric heavy truck, initially delivered for verification to a few major customers such as Pepsi and Walmart. Delivery volume in Q1 2025 was less than 500 units, and actual large-scale capacity expansion is still being postponed.
Supercars and Future Models: The new Roadster supercar has been on the planning list for years and has been delayed repeatedly. In addition, rumors about the $25,000 budget entry-level model, codenamed "Model 2" or "Model Q," have existed for many years. The industry has predicted multiple times—2024 listing, 2025 mass production, 2027 delivery—but Tesla has not yet officially confirmed the specific listing time and mass production details for this model. Musk had already downgraded the R&D priority of economy models in early 2026, with core resources shifting comprehensively to the Cybercab autonomous taxi project.
Energy Storage: Tesla's energy division produces Powerwall home energy storage batteries, Powerpack commercial energy storage systems, and Megapack large-scale commercial electrochemical energy storage systems, holding a very high growth share in the global energy storage market. In 2025, the Shanghai Energy Storage Gigafactory achieved a Megapack planned annual production capacity of 10,000 units, with energy storage scale near 40 GWh.
In 2025, Tesla found itself caught between weak sales and shrinking profits. Global deliveries totaled 1.6361 million units, down 8.6% year-on-year — the steepest annual decline in the company's history. All four quarters saw falling delivery volumes compared to the previous year, with the fourth quarter reaching only 418,000 units, a drop of roughly 15.6%. Revenue fell for the first time ever, coming in at $94.827 billion, a 3% decrease. Automotive revenue slid 10% to $69.526 billion, while net attributable profit plunged 46% to $3.794 billion.
In terms of powertrain mix, the Model 3 and Model Y together accounted for over 95% of Tesla's total deliveries in 2025. Newer models like the Cybertruck and Semi did little to fill the gap left by the core lineup. One bright spot was the energy storage business: the Shanghai Lingang facility produced about 26 GWh of storage capacity in 2025, representing 55.7% of Tesla's global total. While the energy segment's gross margin improved significantly, its scale was far too small to offset the automotive business downturn.
China: Tesla's wholesale sales in China (including both local deliveries and exports) came to 851,700 units in 2025, down 7% from the previous year. Stripping out exports, retail sales in China stood at roughly 625,000 units, a 4.8% decline. For the first 11 months of 2025, sales were 531,900 units, down 7.37% year-on-year. This was the first annual sales drop since Tesla entered the Chinese market. The Shanghai Gigafactory contributed nearly half of Tesla's global production capacity, fulfilling its role as an export hub thanks to its highly efficient production lines (a car rolls off the line every 30 seconds). However, local demand has been increasingly diverted by rivals such as BYD and Xiaomi. In the mid-to-high-end segment, Tesla lost ground to models like the Li Auto L series and NIO ET5T, while the lack of an entry-level model left it exposed in the lower end of the market.
North America: With the U.S. federal EV tax credit set to expire on September 30, 2025, many American consumers rushed to buy before the deadline. This caused Tesla's third-quarter delivery volume to bounce temporarily, shifting the sales driver from price to subsidy expirations. However, the combined effect of tariffs and trade policies in late 2025 severely hurt Tesla's U.S. sales. A study by the U.S. National Bureau of Economic Research argued that Musk's partisan stance may have cost Tesla between 1 million and 1.26 million in potential U.S. sales.
Europe: In 2025, Tesla's sales in Europe fell sharply for five months in a row, and its market share dropped from 1.8% to 1.2%. In key markets like Germany and France, sales slumped by more than a third year-on-year, and in the UK, monthly volumes nearly halved at one point. Although the Model Y remained the top-selling EV in Europe, its lead narrowed considerably amid price wars and geopolitical pressures.
Tesla's technology route underwent a profound directional adjustment from fully electric cars to full AI integration from 2025 to 2026, but the implementation pace of its three major technical pillars—4680 large cylindrical batteries, CTC integrated chassis, and FSD unsupervised autonomous driving system—has become extremely clear.
4680 Large Cylindrical Battery and Full Dry Electrode Mass Production. The 4680 battery is Tesla's self-developed, self-produced core battery technology, adopting a large cylindrical structure with a diameter of 46 mm and height of 80 mm, integrating the full dry electrode process and eliminating the solvent evaporation and drying stages of wet coating. In early 2026, the Texas Austin Gigafactory achieved scaled mass production of the 4680 dry electrode process, with battery mass production yield rate breaking through 92%. The 4680 battery's single cell energy density reached 280-300 Wh/kg, and the new Model Y equipped with 4680 batteries showed significant improvements in energy consumption control and driving range. The Shanghai Gigafactory's 50 GWh 4680 battery production line entered the equipment debugging stage, expected to achieve mass production line-off in Q2 2026.
CTC Chassis Integration Technology. Tesla eliminated the traditional independent battery pack design, arranging and embedding 4680 cells directly into the chassis using epoxy resin potting, making the battery part of the body structure and achieving structural integration with the chassis. CTC technology increased the vehicle's torsional stiffness by 40%, reduced weight by about 10%, and reduced both the number of parts and assembly complexity. Combined with the integrated die-casting process flow with a high proportion, CTC technology further reduced the overall vehicle manufacturing cost by 5-8%.
FSD (Full Self-Driving) and Unsupervised Autonomous Driving. In June 2025, Tesla launched its Robotaxi service pilot in Austin, Texas, with the first batch of 35 modified Model Ys without steering wheels or pedals. In February 2026, FSD regulatory approval made key progress in Europe, with the Netherlands and other countries expected to be among the first to approve. In April 2026, the Cybercab dedicated Robo-taxi model without steering wheels or pedals officially went off the line at the Texas Gigafactory. Tesla's FSD relies on the Dojo supercomputing cluster to process massive driving data, with large models perfecting the pure vision (LiDAR removed) low-cost solution. The Dojo 3 supercomputing project was restarted for R&D in 2026.
Optimus Humanoid Robots. Tesla publicly unveiled its humanoid robot plan for the first time at the 2021 AI Day, and by late 2025 the Optimus project had entered the early practical application stage. Musk also announced that the Fremont Factory would be renovated to produce Optimus humanoid robots, targeting the future industrial and home assistance markets.
Tesla's global production network takes building factories on three continents as its core strategy—forming a local production layout covering major demand areas in the United States, China, and Germany.
The Shanghai Gigafactory is Tesla's most important manufacturing and export hub. This factory contributes nearly half of Tesla's total global capacity, with a supply chain localization rate exceeding 95%. In October 2025, Shanghai factory exports exceeded 35,000 units, creating a 29-month high. As of December 2025, the China factory's 4 millionth vehicle rolled off the line. On December 30, 2025, Tesla's 9 millionth vehicle globally rolled off the line in Shanghai. In February 2025, the Tesla Shanghai Energy Storage Gigafactory officially started production, with a planned annual production of 10,000 units of Megapack large-scale commercial electrochemical energy storage systems, representing an energy storage scale of about 40 GWh. This is Tesla's first energy storage Gigafactory project outside the US.
The Texas Austin Gigafactory is the location of Tesla's headquarters and the absolute core for 4680 battery mass production, and is also responsible for the scaled production of the Cybertruck and Cybercab. The California Fremont Factory is Tesla's longest-running factory, with the Model S and Model X about to cease production for conversion to humanoid robots. The US Nevada Gigafactory is still building its LFP lithium iron phosphate battery production line, expected to be put into production in 2026. The Germany Berlin Gigafactory is responsible for supplying the EU core market with the Model Y. The Mexico Gigafactory plans an investment of $10 billion, covering nearly 4,200 acres, with a planned annual production of 1 million vehicles; it is Tesla's most significant asset for capacity expansion over the next few years.
The year 2026 is Tesla's strategic turning point. On one hand, Tesla's sales data in major automotive markets globally continues to face pressure; on the other hand, Musk has shifted the company's core narrative from "selling more new cars" to "using fewer sales to reach a more realistic AI and Robotaxi capital story."
Robotaxi Annual Entry of Millions of Vehicles. In April 2026, the Cybercab moved from concept to mass production line-off, with an annual production target of 2 million vehicles. Tesla plans to gradually roll out Robotaxi commercial operations in multiple locations, including Austin, Los Angeles, and New York, in the US, while simultaneously pushing and activating the FSD unsupervised version for existing owners.
AI Strategy Comprehensive Repositioning. Musk clearly stated at the 2026 earnings call that "Tesla should be regarded as an AI physical world technology company," converting the Fremont Factory into a humanoid robot factory to achieve an annual production capacity target of 1 million units. Musk significantly delayed the priority of economy entry-level new cars. The company's current stage profit focus is to integrate the 4680+CTC+FSD three technologies into the Cybercab priced below $30,000, further eliminating a large amount of physical hardware such as steering wheels.
Conservative Delivery Target. In March 2026, brokerage and market expectations downgraded Tesla's full-year delivery volume from earlier forecasts to 1.689 million units, with single-digit growth year-on-year. Tesla officially no longer provides precise annual delivery guidance but instead has released comprehensive revenue composition forecasts of "automotive business stabilizing, energy storage business doubling, and productive AI revenue growing significantly."
