Tesla Lead Engineer urges Rivian to optimize R2 for existing Supercharger Network
The Rivian R2 has received much acclaim from the electric vehicle community, and this is highlighted by CEO RJ Scaringe’s announcement stating that the company had received over 68,000 reservations for the upcoming all-electric crossover SUV. But while the Rivian R2 has earned praise for its price, specs, and looks, one aspect of the vehicle has raised eyebrows — its charge port location.
As could be seen in the Rivian R2 prototype that was shown off onstage, as well as the R3 and R3X prototypes that were unveiled after, the electric vehicle maker has opted to equip its upcoming vehicles with a charge port located on the rear passenger side. This, as noted by EV owners, would result in the R2 taking up two spots at Tesla’s V3 and V2 Superchargers.
EV advocate Chris Hilbert, who attended the R2 event, claimed in a post on X that Rivian was able to provide him an answer behind the R2’s charge port location. As per Hilbert, “Rivian is counting on the charging infrastructure to adapt over the next two years. Tesla should not dictate the port location. They are expecting (the) charge port location to not matter by 2026. They are also expecting the future to be curbside charging,” Hilbert wrote, though he also noted that Rivian employees were receptive when he told them that the R2’s charge port location was the vehicle’s only flaw.
I stopped back at the theater to talk to many @Rivian employees tonight. I told them this is the only flaw of the vehicle and they were wrong on charge port location. They did listen to the feedback. They have 2 years to fix it. https://t.co/d9mTqhBFWs— Chris Hilbert (@Hilbe) March 8, 2024
The Rivian R2’s charge port location has since become a well-discussed topic in social media. On Friday morning, Tesla Cybertruck Lead Engineer Wes Morrill weighed in on the matter, encouraging Rivian to move the charge port of the R2 to the rear driver’s side instead. While the Tesla Lead Engineer admitted that Tesla’s V4 Superchargers have longer cables that could accommodate electric vehicle charge port doors in any location, Tesla’s existing network of V3 and V2 Superchargers — which number over 50,000 — are optimized for vehicles whose charge port doors are located in the rear driver’s side.
“RJ Scaringe and Nick Kalayjian, cool product. Great looking prototypes. I know how these things go. There is still time to move the charge port location. It will take some re-engineering but the tools are not kicked off yet. This location will forever doom all Rivian owners to be the jerk taking two spots at a Tesla charger. Don’t do that to your customers.

“I know the Rivian Network has been installed to support the front left/rear right, but there are <500 Adventure Network fast charge handles vs more than 50,000 Supercharger handles. You’ve done the right thing for customers moving to NACS. Take it the last mile and put it in a location that works seamlessly with existing infrastructure. Can be the front right if you are trying to optimize for street parking. Looking forward to charging harmoniously with a great-looking EV,” Morrill wrote in a post on X.
Rivian has highlighted that it puts consumers’ feedback front and center when it designs its vehicles. Considering the substantial requests from EV community members calling for Rivian to move the location of the R2’s charge port door, it would truly be surprising if the electric vehicle maker stands firm and still releases the upcoming all-electric crossover SUV with its original charge port location.

SpaceX is preparing for the 13th integrated flight test of its Starship system, with a targeted launch as early as Thursday, July 16. The 90-minute launch window opens at 5:45 p.m. CT from Starbase in South Texas.
This comes roughly seven weeks after Flight 12 on May 22, underscoring the company’s accelerating pace in its rapid development campaign. The mission will use the latest Starship and Super Heavy V3 vehicles equipped with Raptor 3 engines. Booster 20 will attempt a controlled boostback burn, followed by a splashdown in the Gulf of Mexico, while Ship 40 will follow a suborbital trajectory.

Key objectives for Flight 13 will include demonstrating reliable stage separation, engine performance under various conditions, and controlled reentry.
A major milestone for Flight 13 is the first deployment of 20 next-generation Starlink V3 satellites. These satellites feature advanced laser links for inter-satellite communication, deployable solar arrays, and onboard cameras, six of which will capture imagery of Starship’s heat shield during flight.
Several heat shield tiles on Ship 40 will be painted white to serve as imaging targets, while additional experiments test upgraded tiles on aft flaps, modified attachments on the aft skirt, and load-sensing tiles to measure stresses. The upper stage will also attempt a single Raptor engine relight in space before a targeted splashdown in the Indian Ocean.
These tests build directly on lessons from Flight 12, which introduced the V3 configuration but encountered issues including a booster flip anomaly during boostback and an engine-out event on the ship. Hardware and software modifications on Booster 20 and Ship 40 aim to improve engine relight reliability, startup sequencing, and overall robustness.

The short interval between Flights 12 and 13 highlights SpaceX’s iterative approach. Elon Musk has repeatedly emphasized that Starship launches will become “incredibly common” in the coming years.
The company envisions scaling to rates as high as one launch per hour within 4-5 years, potentially enabling thousands of flights annually. Such cadence is essential for Starship’s goals: establishing orbital refueling for lunar and Mars missions, deploying massive satellite constellations, and making life multiplanetary.
With each flight, Starship edges closer to full reusability and operational maturity. Success on July 16 would mark another step toward routine access to space and the ambitious vision of humanity becoming a spacefaring civilization.
Tesla shared a striking video showcasing the decommissioning of the original Model S and Model X assembly line at its Fremont Factory in Northern California. Completed in just 46 days, the teardown involved heavy machinery dismantling concrete pits, removing robotic arms and conveyors, and clearing the space for new production.
The post, captioned “End of an era,” captured both the end of a historic chapter and Tesla’s aggressive pivot toward its next major initiative, Optimus.

The decision to retire the Model S and Model X originated during Tesla’s Q4 2025 Earnings Call in late January 2026. CEO Elon Musk announced that production of the company’s flagship sedan and SUV would wind down by the end of Q2 2026, describing it as bringing the programs to an “honorable discharge.”
Custom orders ceased around early April 2026, with the final vehicles rolling off the line in early May. A special signature delivery ceremony on May 20 marked the emotional close for these vehicles, which had defined Tesla’s early success and luxury EV segment since the Model S launch in 2012.
The primary reason for tearing down the lines was to repurpose the valuable factory floor space for high-volume production of Tesla’s Optimus humanoid robot. Musk had indicated on Earnings Calls that the Fremont S/X line would be replaced by a dedicated Optimus manufacturing line targeting a capacity of one million units per year.
This move aligns with Tesla’s broader strategic shift from traditional vehicle manufacturing toward robotics and artificial intelligence, leveraging the company’s expertise in autonomy, AI training, and high-volume production.
Optimus, Tesla’s general-purpose humanoid robot, is designed to perform repetitive or dangerous tasks in factories, warehouses, and eventually homes. Powered by Tesla’s AI and Neural Networks, it aims to be a versatile, affordable platform. Production of Optimus Gen 3 is already underway in limited form at Fremont, with full-scale output on the converted line expected to begin in late July or August.
Tesla is targeting rapid scaling, with internal ambitions pointing toward tens or even hundreds of thousands of units annually by the end of 2026.
Longer-term, Tesla is constructing a much larger second-generation Optimus facility at Giga Texas, with potential capacity reaching millions of units per year. The company views Optimus as a transformative product that could eventually surpass its automotive business in scale and value, enabling widespread deployment of useful robots across industries. CEO Elon Musk has even predicted it would be the most popular product of all-time.
As one era closes at Fremont, another is rapidly taking shape.
Elon Musk posted a candid admission on his social media platform X on June 9, declaring that he had been “clearly wrong” about Anthropic. The statement marked a notable reversal from his earlier skepticism toward the AI company.
In September, Musk had written, “Winning was never in the set of possible outcomes for Anthropic,” reflecting his view at the time that the startup had lacked the foundation or even the trajectory to succeed in what is an incredibly intense race for advanced artificial intelligence.
Musk’s latest post came amid discussion of Anthropic’s reliance on external compute resources. He praised the company’s progress, stating that Anthropic is “obviously currently the leader in AI” and that “no company has released a model as good as Mythos/Fable,” with expectations of a strong follow-up in Mythos 2.
The tone shifted dramatically from dismissal to acknowledgement of superior performance.
I was clearly wrong about Anthropic. They are obviously currently the leader in AI. No company has released a model as good as Mythos/Fable and they will undoubtedly have Mythos 2 ready soon.
And I would never cut them off in a way that hurt them badly, even as a competitor.…
— Elon Musk (@elonmusk) July 9, 2026
The context of Musk’s comments added significance. Anthropic has been operating under a recent compute deal with SpaceXAI, Musk’s AI infrastructure-focused venture. The pair entered a short-term GPU lease agreement initiated in May, providing Anthropic access to critical computing power for training and deploying its frontier models.

Some observers had speculated that Musk could leverage this dependency to disadvantage a rival. Musk directly addressed the possibility, writing, “I would never cut them off in a way that hurt them badly, even as a competitor. That’s not my style.”
To support his commitment to ethical competition, Musk referenced concrete examples from his other companies. Tesla famously open-sourced its entire portfolio of electric vehicle patents in 2014. The move was designed to accelerate the global adoption of sustainable transportation technology rather than protect proprietary advantages.
Tesla also made its Supercharger network available to competing electric vehicle manufacturers, transforming what could have remained an exclusive charging ecosystem into a shared infrastructure that benefits the broader industry and reduces barriers for EV adoption.
Musk further pointed to SpaceX’s practices, noting that the company launches satellites for competing commercial systems “with no increase in price or use of unfair terms.” He extended the principle to his social platform, observing that “even my worst enemies attack me on this platform,” underscoring preference for open discourse over retaliation.
These examples have illustrated Musk’s long-standing philosophy that long-term technological progress is best served by open competition and infrastructure sharing rather than leveraging market power to stifle rivals. In the fast-evolving AI sector, where compute resources and model capabilities determine leadership, Musk’s stance suggests a willingness to compete on innovation and performance alone.
Musk’s admission arrives as SpaceXAI itself advances its own frontier models while maintaining business relationships across the ecosystem. By publicly correcting his earlier assessment and reaffirming principles of fair play, Musk highlights a model of competition that prioritizes advancement of the field over short-term tactical advantages.
