During Tesla’s Battery Day event, Elon Musk and Drew Baglino announced that its pilot Roadrunner cell production line would be capable of producing about 10 GWh worth of batteries per year. The facility’s output was almost spoken as an aside, with both executives simply stating its target as a given. A closer look at the Roadrunner line’s planned annual output shows that Tesla has created something that’s incredibly disruptive and innovative at the same time.  

As noted by Benchmark Mineral Intelligence, a market intelligence publisher for the lithium-ion battery to electric vehicle (EV) supply chain, the Roadrunner line’s 10 GWh output actually makes it the world’s 13th-largest battery production facility in the world. Granted, the facility is still in the process of being ramped, but once it achieves its full potential, it would be making a significant amount of batteries. Today, after all, Gigafactory Nevada’s output still stands below 40 GWh, and that’s with a monster battery factory that’s already considered as the largest in the world.

The disruption of Tesla’s next-generation battery and cell production system becomes even more evident when one considers just how compact the system is. The Roadrunner line is located in Tesla’s Kato Road facility, which is comprised of two buildings that cover 184,880 sq ft combined, as per the company’s filings to the City of Fremont. To build a 10 GWh battery production plant from such a space is something truly remarkable. 

It should also be considered that the 10 GWh Roadrunner system is a pilot production line, which means that it’s still bound to be improved over time. The Kato Road facility may hold its place as the world’s 13th-largest battery production plant when it hits its target output, but there will likely be very little that could stop Tesla from upgrading the facility even further, or at least as soon as improvements become available. Such is the culture of Tesla, after all. 

The Roadrunner line’s 10 GWh output is nothing to scoff at. Back in 2010, the entire battery production industry produced 20 GWh, as per data from the European Commission. This means that the pilot Roadrunner line has an output equal to half the world’s battery production output a decade ago. Interestingly enough, neither Elon Musk nor Drew Baglino emphasized these points during the Battery Day event. Any other carmaker would likely have highlighted such a point.

The innovations that were announced on Battery Day have the potential to change not only the electric vehicle sector but the transportation industry as a whole. With its new battery tech, Tesla will be able to produce batteries at the terawatt level from facilities that are smaller than the completed iteration of Gigafactory Nevada, which is expected to produce 150 GWh. This is key to the company’s long-term goal, which includes producing 20 million vehicles for the global auto market by 2030.

Ford CEO Farley says Tesla is not who to look at for EV expertise

Interestingly, Farley has been one of the most hellbent CEOs in terms of a legacy automaker standpoint to push the EV effort. It did not go according to plan, as Ford took a $19.5 billion charge and retreated from its EV push in late 2025.

Ford CEO Jim Farley said in a recent podcast interview that Tesla is not who Americans should look at to beat Chinese carmakers.

The comments have sparked quite a bit of outrage from Tesla fans on X, the social media platform owned by Elon Musk.

Farley said that Chinese automakers are better examples of how to beat competitors. He said (via the Rapid Response Podcast):

“If you’re an American and you want us to beat the Chinese in the car business, you’re all going to want to pay attention, not necessarily to Tesla. Nothing against Tesla—they’ve been doing great—but they really don’t have an updated vehicle. The best in the business for us, cost-wise and competition-wise, supply chain, manufacturing expertise, and the I.P. in the vehicle, was really BYD. In this next cycle of EV customers in the U.S., they want pickups and utilities and all these different body styles. But they want them at $30,000, not $50,000. Like the first inning, they want them affordably.”

Despite Farley’s synopsis, it is worth mentioning that Tesla had the best-selling passenger vehicle in the world last year, and in China in March, as the Model Y continued its global dominance over other vehicles.

Musk responded to Farley’s comments by stating:

“This is before Supervised FSD is approved in China. Limiting factor is production output in Shanghai.”

Interestingly, Farley has been one of the most hellbent CEOs in terms of a legacy automaker standpoint to push the EV effort. It did not go according to plan, as Ford took a $19.5 billion charge and retreated from its EV push in late 2025.

Ford cancels all-electric F-150 Lightning, announces $19.5 billion in charges

Instead, Ford is “doubling down on its affordable” EVs and said it would pivot from its previous plans.

Reaction from Tesla fans was pretty much how you would expect. Many said they have lost a lot of respect for Farley after his comments; others believe he is the last CEO anyone should be taking advice on EVs from.

Nevertheless, Farley’s plans are bold and brash; many consider Tesla the most ideal company to replicate EV efforts from. It will be interesting to see if Ford can rebound from this big adjustment, and hopefully, Farley’s plans to replicate efforts from BYD work out the way he hopes.

SpaceX wins its first MARS contract but it comes with a catch

NASA awarded SpaceX a $175 million Mars rover contract while the White House proposes cutting the mission.

NASA just signed a $175.7 million contract with SpaceX to launch a Mars rover that the White House is simultaneously trying to defund. The contract, awarded on April 16, 2026, tasks SpaceX’s Falcon Heavy with launching the European Space Agency’s (ESA) Rosalind Franklin rover from Kennedy Space Center in Florida, no earlier than late 2028. It would mark the first time SpaceX has ever sent a payload to Mars.

Under NASA’s Rosalind Franklin Support and Augmentation project, known as ROSA, the agency is providing braking engines for the rover’s descent stage, radioisotope heater units that use decaying plutonium to keep the rover warm on the Martian surface, additional electronics, and a mass spectrometer instrument, as noted by SpaceNews.

Those nuclear heating units are the reason an American rocket was required at all. U.S. export controls on radioisotope technology mean any payload carrying them must launch on a domestic vehicle, which narrowed the field to SpaceX and United Launch Alliance. Falcon Heavy’s pricing made it the practical choice.

SpaceX is quietly becoming the U.S. Military’s only reliable rocket

Falcon Heavy debuted in February 2018 and has 11 launches to its record. The rocket has not flown since October 2024, when it sent NASA’s Europa Clipper toward Jupiter. The three-core design, built from modified Falcon 9 first stages, gives it the lift capacity needed for deep space planetary missions that a single Falcon 9 cannot reach.

The Rosalind Franklin rover has been sitting in storage in Europe for years. It was originally due to launch in 2022 as a joint mission with Russia, but Russia’s invasion of Ukraine ended that partnership, leaving the rover built but stranded without a launch vehicle or landing hardware. NASA stepped back in through a 2024 agreement with ESA to rescue the mission. The rover is designed to drill up to two meters below the Martian surface in search of evidence of past life, a science objective no previous mission has attempted at that depth.

The contradiction at the center of this story is hard to ignore. The White House’s fiscal year 2027 budget proposal included no funding for ROSA and did not mention the mission at all in the detailed congressional justification document released April 3.

Musk has long argued that reaching Mars is not optional. “We don’t want to be one of those single planet species, we want to be a multi-planet species.” Whether this particular mission survives Washington’s budget fight, the Falcon Heavy contract means SpaceX is now formally on record as the rocket that could get humanity’s next Mars science mission off the ground.

The timing of this contract carries extra weight given that SpaceX filed confidentially with the SEC in early April and is targeting an IPO roadshow in the week of June 8. It would be the largest public offering in history.

Tesla Q1 Earnings: What Elon Musk and Co. will answer during the call

Published

Tesla (NASDAQ: TSLA) is set to hold its Earnings Call for the first quarter of 2026 on Wednesday, and there are a lot of interesting things that are swirling around in terms of speculation from investors.

With the company’s executives, including CEO Elon Musk, answering a handful of questions that investors submit through the Say platform, fans want to know a lot of things about a lot of things.

These five questions come from Retail Investors, who are normal, everyday shareholders:

  1. When will we have the Optimus v3 reveal? When will Optimus production start, since we ended the Model S and Model X production earlier than mid-year? What’s the expected Optimus production rate exiting this year? What are the initial targeted skills?
  2. What milestones are you targeting for unsupervised FSD and Robotaxi expansion beyond Austin this year, and how will that drive recurring revenue?
  3. How will Hardware 3 cars reach Unsupervised Full Self-Driving?
  4. When do you expect Unsupervised Full Self-Driving to reach customer cars?
  5. When will Robotaxi expand past its current limited rollout?

Additionally, these are currently the three questions that are slated to be answered by Institutional Firms, which also answer a handful of questions during the call:

  1. Now that FSD has been approved in the Netherlands and is expected to launch across Europe this summer, can you discuss your Robotaxi strategy for the region?
  2. What enabled you to finish the AI5 tapeout early and were there any changes to the original vision? Last week, Elon said AI5 will go into Optimus and the Supercomputer, but one month ago said it would go into the Robotaxi. Has AI5 been dropped from the vehicle roadmap?
  3. Given the recent NHTSA incident filings, can you update us on the Robotaxi safety data? If safety validation remains the primary bottleneck, why not deploy thousands of vehicles to accelerate the removal of the safety driver?

The questions range through every current Tesla project, including FSD expansion and Optimus. However, many of the answers we will get will likely be repetitive answers we’ve heard in the past.

This is especially pertinent when the questions about when Unsupervised FSD will reach customer cars: we know Musk will say that it will happen this year. Is Tesla capable of that? Maybe. But a more transparent answer that is more revealing of a true timeline would be appreciated.

Hardware 3 owners are anxiously awaiting the arrival of FSD v14 Lite, which was promised to them last year for a release sometime this year.

The Earnings Call is set to take place on Wednesday at market close.
