Tesla Model 3 single-piece casting will come, but not anytime soon, Elon Musk says
Tesla will “likely” switch the Model 3 sedan to a single-piece casting design in the future, CEO Elon Musk said in an interview with Sandy Munro. However, the design will not be on its way anytime soon, as Musk said the Berlin and Texas Gigafactories need to have production efforts well underway to sustain demand fulfillment.
The Model 3’s current design is not a single piece casting and is comprised of 70 different metal parts welded together to create the vehicle’s underbody. Tesla improved upon this design in its Model Y crossover by using a massive, single-piece casting to eliminate 69 total parts. The single-piece design is effective for manufacturing purposes and increases structural rigidity in the event of an accident.
As the Model Y and Model 3 dominate Tesla’s current sales and delivery figures, Munro mentioned to Musk that he was disappointed that his new Model 3 teardown did not reveal a single piece casting similar to the Model Y design. However, Musk indicated Tesla’s mass-market sedan would eventually use the single-piece casting, it would just take its next two production facilities to be in operation for it to happen.
Musk told Munro:
“At some point, we probably will switch to a single-piece casting, but I think we need to get the Texas factory and the Berlin factory going. We do have an issue. It is hard to change the wheels on the bus when it is going 80 MPH down the highway. So, Model 3 is…well, was most of our volume. Model Y will exceed Model 3, but we just need an opportunity to redo the factory without blowing the cash flow of the company.”
In its Q1 2020 Update Letter, Tesla showed the two designs. The Model Y casting (right) was two pieces at this point in time. Thanks to the introduction of Tesla’s Giga Press from IDRA, the automaker has eliminated the two-piece design in favor of a massive one-piece casting. The elimination of so many parts was a huge advantage for Munro, who detailed the casting advantages in several teardown episodes last year.
Tesla Model Y owner Tony Pham then showed the one-piece casting design on his vehicle while having a third-party accessory installed into his all-electric crossover. Pham’s Model Y was delivered in late 2020, proving that Tesla has been utilizing the one-piece design for several months.

Tesla’s single-piece design is widely thought by automotive engineers, including Munro, to be the most advantageous way to build a car. In Munro’s opinion, other automakers have ignored a single-piece design’s advantages due to their stubbornness to keep things the same. “Thousands of engineers, big-time executives, walk by [the idea]. They don’t do it,” Munro said.
One of Tesla’s manufacturing process’s main advantages is that it continues to refine its techniques and never admits that its current processes are the best way to handle things. Tesla is always looking to improve the situation of its manufacturing and production lines, always seeking different techniques and new ways to build its vehicles. The issue now is that Tesla’s vehicles are becoming so popular that its limited production lines cannot be halted to update some production techniques, especially to mass-market vehicles that have been produced for several years. Musk’s analogy of the bus going 80 MPH down the highway is extremely accurate, especially as Tesla is coming off of its largest production and delivery year in company history. Halting Model 3 production lines for an update to the vehicle’s casting design would be detrimental at the current time.
While it is likely that Model 3 single-piece castings could happen down the road, it is not something to expect soon. With Musk indicating that Giga Berlin and Giga Texas need to be in operation for this to occur, these facilities will likely need to have Model 3 production numbers high enough to offset the closure of lines at Giga Shanghai and Fremont. With Berlin focusing on Model Y production initially, it is likely that Model 3 lines will not be ramped for at least a year, so the single-piece Model 3 casting may not be seen until at least 2023.

Tesla’s Q1 delivery figures show Elon Musk was right
On the surface, the numbers reflect a mature EV market facing competition, softening demand, and the loss of certain incentives. Yet they also quietly validate a prediction Elon Musk has repeated for years: Tesla’s traditional auto business is becoming far less central to the company’s future.
Tesla reported its Q1 delivery figures on Thursday, and the figures — solid but unspectacular — show that CEO Elon Musk was right about what the company’s most important production and division would be.
We are seeing that shift occur in real time.
Tesla delivered 358,023 vehicles in the first quarter of 2026, according to the company’s official report released April 2.
The figure represents modest year-over-year growth of roughly 6 percent from Q1 2025’s 336,681 deliveries but a sharp sequential drop from Q4 2025’s 418,227. Production reached 408,386 vehicles, while energy storage deployments hit 8.8 GWh.
On the surface, the numbers reflect a mature EV market facing competition, softening demand, and the loss of certain incentives. Yet they also quietly validate a prediction Elon Musk has repeated for years: Tesla’s traditional auto business is becoming far less central to the company’s future.
Musk has long argued that vehicles alone will not define Tesla’s value.
Optimus Will Be Tesla’s Big Thing
In September 2025, Musk stated bluntly on X that “~80% of Tesla’s value will be Optimus,” the company’s humanoid robot.
He has described Optimus as potentially “more significant than the vehicle business over time.” Those comments were not abstract futurism. In January 2026, during the Q4 2025 earnings call, Musk announced the end of Model S and X production, framing it as an “honorable discharge,” he called it.
Those are the biggest factors.
~80% of Tesla’s value will be Optimus.
— Elon Musk (@elonmusk) September 1, 2025
The Fremont factory space, once dedicated to those flagship sedans, is being converted into an Optimus manufacturing line, with a long-term target of one million robots per year from that single facility alone.
The Q1 2026 numbers arrive at precisely the moment this strategic pivot is accelerating. Model 3 and Y deliveries totaled 341,893 units, while “other models” (including Cybertruck, Semi, and the final wave of S/X) added 16,130.
Growth is no longer explosive because Tesla is no longer chasing volume at all costs. Instead, the company is reallocating capital and factory floor space toward autonomy, energy storage, and robotics, businesses Musk believes will command far higher margins and enterprise value than incremental car sales.
Delivery Hits and Misses are Becoming Less Important
Wall Street’s pre-release consensus had pegged deliveries near 365,000. Coming in below that estimate might have rattled investors focused solely on automotive metrics. Yet Musk’s thesis has never been about maximizing quarterly vehicle shipments.
Tesla, he has insisted, “has never been valued strictly as a car company.”
The modest Q1 auto performance, paired with the deliberate wind-down of legacy programs and the ramp of Optimus, underscores that point. While EV demand stabilizes, Tesla is building the infrastructure for Robotaxis and humanoid robots that could dwarf today’s car business.
The future is here, and it is happening. It’s funny to think about how quickly Tesla was able to disrupt the traditional automotive business and force many car companies to show their hand. But just as fast as Tesla disrupted that, it is now moving to disrupt its own operation.
Cars, once the only recognizable and widely-known division of Tesla, is now becoming a background effort, slowly being overtaken by the company’s ambitions to dominate AI, autonomy, and robotics for years to come.
Critics may still view the shift as risky or premature. But the Q1 figures, solid but unspectacular in the auto segment, illustrate exactly what Musk has been signaling: the era when Tesla’s valuation rose and fell with every Model Y delivery is ending.
The company’s long-term bet is on AI-driven products that turn vehicles into high-margin robotaxis and factories into robot foundries. Thursday’s delivery report did not just meet the market’s tempered expectations; it proved Elon Musk was right all along.
The car business, once everything, is quietly becoming an important piece of a much larger puzzle.

Tesla reports Q1 deliveries, missing expectations slightly
The figure, however, fell short of Wall Street’s consensus estimate of 365,645 units, reflecting ongoing headwinds in the global EV market.
Tesla reported deliveries for the first quarter of 2026 today, missing expectations set by Wall Street analysts slightly as the company aims to have a massive year in terms of sales, along with other projects.
Tesla delivered 358,023 vehicles in the first quarter of 2026, marking a 6.3 percent increase from 336,681 vehicles in Q1 2025.
The figure, however, fell short of Wall Street’s consensus estimate of 365,645 units, reflecting ongoing headwinds in the global EV market. Production reached approximately 362,000 vehicles, with Model 3 and Model Y accounting for the vast majority. The results come as Tesla navigates softening demand, intensifying competition in China and Europe, and the expiration of key U.S. federal tax incentives.

Energy storage deployments provided a bright spot, hitting a record 8.8 GWh in Q1. This underscores the accelerating momentum in Tesla’s energy segment, which has become a critical growth driver even as automotive volumes stabilize.
Year-over-year, the energy business continues to outpace vehicle sales, with analysts noting strong backlog demand for Megapack systems amid rising grid-scale needs for renewables and AI data centers.
Looking ahead, analysts project full-year 2026 vehicle deliveries in the range of 1.69 million units—a modest 3-5% rise from roughly 1.64 million in 2025.
Growth is expected to accelerate in the second half as production ramps and new incentives emerge in select markets. However, risks remain: persistent high interest rates, price competition from legacy automakers and Chinese EV makers, and potential margin pressure could cap upside.
Tesla has not issued official full-year guidance, but executives have signaled confidence in sequential quarterly improvements driven by cost reductions and refreshed lineups.
By the end of 2026, Tesla plans several major product launches to reignite momentum. The refreshed Model Y, including a new 7-seater variant already rolling out in select markets, is expected to boost family-oriented sales with updated styling, efficiency gains, and interior enhancements.
Autonomous ambitions remain central to Tesla’s mission, and that’s where the vast majority of the attention has been put. Volume production of the Cybercab (Robotaxi) is targeted to begin ramping in 2026, potentially unlocking new revenue streams through unsupervised Full Self-Driving (FSD) deployment.
A next-generation affordable EV platform, possibly under $30,000, is also in advanced planning stages for 2026 or 2027 introduction. On the energy front, the Megapack 3 and larger Megablock systems will drive further deployment scale.
While Q1 highlights transitional challenges in autos, Tesla’s diversified roadmap, spanning refreshed consumer vehicles, commercial trucks, Robotaxis, and explosive energy growth, positions the company for a stronger second half and beyond. Investors will watch Q2 closely for signs of sustained recovery, especially with new vehicles potentially on the horizon.

NASA sends humans to the Moon for the first time since 1972 – Here’s what’s next
NASA’s Artemis II launched four astronauts toward the Moon on the first crewed lunar mission since 1972.

NASA launched four astronauts toward the Moon on April 1, 2026, marking the first crewed lunar mission since Apollo 17 in December 1972. The Artemis II mission lifted off from Kennedy Space Center aboard the Space Launch System rocket at 6:35 p.m. EDT, sending commander Reid Wiseman, pilot Victor Glover, mission specialist Christina Koch, and Canadian astronaut Jeremy Hansen on a 10-day journey around the far side of the Moon and back.
The mission does not include a lunar landing. It is a test flight designed to validate the Orion spacecraft’s life support systems, navigation, and communications in deep space with a crew aboard for the first time. If the crew reaches the planned distance of 252,000 miles from Earth, they will set a new record for the farthest any human has ever traveled, surpassing even the Apollo 13 distance record.
As Teslarati reported, SpaceX holds a central role in what comes next. The Starship Human Landing System is under contract to carry astronauts to the lunar surface for Artemis IV, now targeting 2028, after NASA restructured its mission sequence due to delays in Starship’s orbital refueling demonstration. Before any Moon landing happens, SpaceX must prove it can transfer propellant between two Starships in orbit, something no rocket program has done at this scale.
The last time humans left Earth’s orbit was 53 years ago. Gene Cernan and Harrison Schmitt of Apollo 17 were the final people to walk on the Moon, a record that stands to this day. Elon Musk has long argued that returning is not optional. “It’s been now almost half a century since humans were last on the Moon,” Musk said. “That’s too long, we need to get back there and have a permanent base on the Moon.”
The Artemis program involves 60 countries signed onto the Artemis Accords, and this mission sets several firsts beyond distance. Glover becomes the first person of color to travel beyond low Earth orbit, Koch the first woman, and Hansen the first non-American astronaut to reach the Moon’s vicinity. According to NASA’s live mission updates, the spacecraft’s solar arrays deployed successfully after liftoff and the crew completed a proximity operations demonstration within the first hours of flight.
Artemis II is step one. The Moon landing and the permanent lunar base come later. But after more than five decades, humans are heading back.
