Another excerpt from biographer Walter Isaacson’s book on Elon Musk shares new details about Tesla’s next-generation vehicle platform, including plans for a different build location than the automaker previously reported.
In the excerpt, which Axios published on Friday, Isaacson details Musk’s well-documented desire to build Tesla’s next-generation electric vehicle (EV) platform used for self-driving cars. Although Tesla announced plans earlier this year to build the next-gen EV at an upcoming Gigafactory in Mexico, Isaacson says that Musk changed the initial build location of the robotaxi platform to Gigafactory Austin as recently as May.
“Tesla engineering will need to be on the line to make it successful, and getting everyone to move to Mexico is never going to happen,” Musk told Isaacson.
While Giga Mexico is still expected to be built out for the new generation of Tesla’s EVs, the excerpt details Musk’s desire to have the automaker’s design engineers even closer to the assembly process.
This would allow engineers to provide feedback instantly, and rather than relocating these engineers to Giga Mexico, Musk reportedly decided to change the new platform’s initial production location to Tesla’s headquarters at Giga Texas.
Samuel García Sepúlveda, governor of the Mexican state Nuevo León, where Giga Mexico will be built, said earlier this year that the automaker would build a production line from the ground up to build Tesla’s $25,000 compact car outside of Monterrey. A move to debut the initial production of the upcoming EV at Giga Texas wouldn’t necessarily change this detail.
Beyond Giga Texas being Tesla’s headquarters, it’s also where Musk’s primary workspace is located, and it includes a high-speed assembly line for production that includes updated automation functionality.
Tesla next-gen car: Elon Musk confirms two new EVs that can hit 5M per year
According to Isaacson in another report from Axios, the upcoming robotaxi EV platform is expected to be inspired by the Cybertruck, built on the same architecture as the $25,000 car design. The EVs are expected to be similar, even using the same assembly line. However, one key difference between the two mass-market EVs is that the robotaxi may not necessarily include a steering wheel, while the passenger vehicle version would.
Isaacson also shares details from a design review session in February for the EVs, during which Tesla chief designer Franz von Holzhausen showed the $25,000 car design and the robotaxi design next to each other. Musk responded with enthusiasm — particularly due to their futuristic, Cybertruck-like design.
“When one of these comes around a corner, people will think they are seeing something from the future,” Musk said during the meeting.
Still, Isaacson notes that Musk’s excitement is far higher for the robotaxi project than for the $25,000 car, especially given how much the Tesla CEO expects to see transportation redefined with the self-driving vehicle platform. According to von Holzhausen, the Tesla team even had to convince Musk to use the same vehicle architecture for both the $25,000 vehicle and the robotaxi design.
“It’s really not that exciting of a product,” Musk previously said of the mass-market EV.

Tesla confirmed HW3 can’t do Unsupervised FSD but there’s more to the story
Tesla confirmed HW3 vehicles cannot run unsupervised FSD, replacing its free upgrade promise with a discounted trade-in.
Tesla has officially confirmed that early vehicles with its Autopilot Hardware 3 (HW3) will not be capable of unsupervised Full Self-Driving, while extending a path forward for legacy owners through a discounted trade-in program. The announcement came by way of Elon Musk in today’s Tesla Q1 2026 earnings call.

The history here matters. HW3 launched in April 2019, and Tesla sold Full Self-Driving packages to owners on the understanding that the hardware was sufficient for full autonomy. Some owners paid between $8,000 and $15,000 for FSD during that period. For years, as FSD’s AI models grew more demanding, HW3 vehicles fell progressively further behind, eventually landing on FSD v12.6 in January 2025 while AI4 vehicles moved to v13 and then v14. When Musk acknowledged in January 2025 that HW3 simply could not reach unsupervised operation, and alluded to a difficult hardware retrofit.
The near-term offering is more concrete. Tesla’s head of Autopilot Ashok Elluswamy confirmed on today’s call that a V14-lite will be coming to HW3 vehicles in late June, bringing all the V14 features currently running on AI4 hardware. That is a meaningful software update for owners who have been frozen at v12.6 for over a year, and it represents genuine effort to keep older hardware relevant. Unsupervised FSD for vehicles is now targeted for Q4 2026 at the earliest, with Musk describing it as a gradual, geography-limited rollout.
For HW3 owners, the over-the-air V14-lite update is welcomed, and the discounted trade-in path at least acknowledges an old obligation. What happens next with the trade-in pricing will define how this chapter ultimately gets written. If Tesla prices the hardware path fairly, acknowledges what early adopters are owed, and delivers V14-lite on the June timeline it committed to today, it has a real opportunity to convert one of the longest-running sore subjects among early adopters into a loyalty story.

Tesla isn’t joking about building Optimus at an industrial scale: Here we go
Tesla’s Optimus factory in Texas targets 10 million robots yearly, with 5.2 million square feet under construction.
Tesla’s Q1 2026 Update Letter, released today, confirms that first generation Optimus production lines are now well underway at its Fremont, California factory, with a pilot line targeting one million robots per year to start. Of bigger note is a shared aerial image of a large piece of land adjacent to Gigafactory Texas, that Tesla has prominently labeled “Optimus factory site preparation.”
Permit documents show Tesla is seeking to add over 5.2 million square feet of new building space to the Giga Texas North Campus by the end of 2026, at an estimated construction investment of $5 billion to $10 billion. The longer term production target for that facility is 10 million Optimus units per year. Giga Texas already sits on 2,500 acres with over 10 million square feet of existing factory floor, and the North Campus expansion is being built to support multiple projects, including the dedicated Optimus factory, the Terafab chip fabrication facility (a joint Tesla/SpaceX/xAI venture), a Cybercab test track, road infrastructure, and supporting facilities.

Texas makes strategic sense beyond the existing infrastructure. The state’s tax structure, lower labor costs relative to California, and the proximity to Tesla’s AI training cluster Cortex 1 and 2, both located at Giga Texas and now totaling over 230,000 H100 equivalent GPUs, means the Optimus software stack and the factory producing the hardware will share the same campus. Tesla’s Q1 report also confirmed completion of the AI5 chip tape out in April, the inference processor designed specifically to power Optimus units in the field.
As Teslarati reported, the Texas facility is intended to house Optimus V4 production at full scale. Musk told the World Economic Forum in January that Tesla plans to sell Optimus to the public by end of 2027 at a price between $20,000 and $30,000, stating, “I think everyone on earth is going to have one and want one.” He has previously pegged long term demand for general purpose humanoid robots at over 20 billion units globally, citing both consumer and industrial use cases.
Tesla (NASDAQ: TSLA) reported its earnings for the first quarter of 2026 on Wednesday afternoon. Here’s what the company reported compared to what Wall Street analysts expected.
The earnings results come after Tesla reported a miss on vehicle deliveries for the first quarter, delivering 358,023 vehicles and building 408,386 cars during the three-month span.
As Tesla transitions more toward AI and sees itself as less of a car company, expectations for deliveries will begin to become less of a central point in the consensus of how the quarter is perceived.
Nevertheless, Tesla is leaning on its strong foundation as a car company to carry forward its AI ambitions. The first quarter is a good ground layer for the rest of the year.
Tesla Q1 2026 Earnings Results
Tesla’s Earnings Results are as follows:
- Non-GAAP EPS – $0.41 Reported vs. $0.36 Expected
- Revenues – $22.387 billion vs. $22.35 billion Expected
- Free Cash Flow – $1.444 billion
- Profit – $4.72 billion
Tesla beat analyst expectations, so it will be interesting to see how the stock responds. IN the past, we’ve seen Tesla beat analyst expectations considerably, followed by a sharp drop in stock price.
On the same token, we’ve seen Tesla miss and the stock price go up the following trading session.
Tesla will hold its Q1 2026 Earnings Call in about 90 minutes at 5:30 p.m. on the East Coast. Remarks will be made by CEO Elon Musk and other executives, who will shed some light on the investor questions that we covered earlier this week.
