Ford’s 1.25-million-pound F-150 EV demo was easier than it looked, explains engineer
Last week, Ford made headlines when it released a video of its upcoming F-150 electric pickup truck pulling what could only be described as an unreal amount of weight. In the demonstration, the upcoming vehicle pulled ten double-decker rail cars, both empty and loaded with 42 gas-burning F-150s. The weight of the rail cars with the pickups in them was a whopping 1.25 million pounds, but the F-150 EV was able to pull everything without any issue.
The demonstration was incredibly impressive, instantly eclipsing the feats of strength from other notable vehicles like the Tesla Model X, which pulled a Boeing 787 Dreamliner, and the Toyota Tundra, which towed a Space Shuttle. According to auto enthusiast and mechanical engineer Jason Fenske of YouTube’s Engineering Explained channel, though, Ford’s demonstration is actually far easier than it looked.
Fenske notes that both the 787 Dreamliner and Space Shuttle pulled by the Model X and Tundra rode on rubber tires. On the other hand, the rail cars pulled by the electric Ford F-150 rested on steel wheels riding on steel railroad tracks. This, the engineer explains, makes a notable difference, particularly with regards to the coefficient of rolling resistance (the ratio of the force required to pull a rotational mass).
“Steel does not deform much at all, which is why railroads use steel wheels on steel tracks. This adds up to an extremely low coefficient of rolling resistance—about 0.0015. To pull a 10,000-pound train across a level surface, you only need a 15-pound force. For a truck to move a 1.25-million-pound train, it only requires about 1,875 pounds of force,” Fenske wrote.
The engineer adds that generally, the maximum force a 4WD truck can generate will be equivalent to its weight, mostly due to the grip of its tires. Since the electric Ford F-150 prototype used in the demonstration was most certainly over 1,875 pounds, it would really have no issues pulling the 1.25-million-pound load. Had the F-150 EV attempted such a feat with a load equipped with pneumatic tires on pavement, the demonstration would most definitely have resulted in a much different outcome.
Fenske’s points were outlined in an article on Road & Track, which delved more into the math behind Ford’s demonstration. A Ford spokesperson has responded to Fenske’s arguments, pointing out that the engineer’s calculations did not evaluate acceleration. The engineer wrote that he is currently waiting for Ford to provide more information about the demo, in order to calculate exactly how much power the demonstration took.
While the F-150 EV’s feat of strength could be explained by the automaker’s choice of cargo, the demonstration remains pretty impressive nonetheless. It does, if any, raise interest in the upcoming vehicle. Unfortunately, Ford Chief Product Development Officer Hau Thai-Tang noted during an interview with Yahoo Finance’s The First Trade that the all-electric version of the F-150 is still “a couple of years out,” though a hybrid version will be released in 2020.

SpaceX’s newest logo confirms everything about what it’s become
SpaceX officially absorbed xAI under the SpaceXAI brand, completing the largest private merger in history.
SpaceX made its corporate transformation official in May 2026 when Elon Musk posted on X that xAI would cease to exist as a standalone company. “xAI will be dissolved as a separate company, so it will just be SpaceXAI, the AI products from SpaceX,” he wrote.
A new SpaceXAI logo was announced today, visually embedding the xAI letters inside the SpaceX identity, which can be seen as a deliberate design choice that signals the merger is not a partnership but a full absorption and XAi a core function of the same company. The same way Starlink is not a separate brand but a SpaceX product. The announcement closed the loop on a process that began February 2, 2026, when SpaceX acquired xAI in the largest private merger in history, valued at $1.25 trillion. SpaceX at $1 trillion and xAI at $250 billion.

The reason SpaceX bought xAI was stated plainly by Musk at the time of the deal: to build orbital data centers. SpaceX had simultaneously filed with the FCC to launch up to one million satellites designed to function as AI compute nodes in low Earth orbit, escaping what Musk described as the energy constraints limiting AI development on Earth.
xAI provided the AI software stack, with Grok, the X platform, and the Colossus supercomputer infrastructure in Memphis with over 220,000 NVIDIA GPUs, while SpaceX provided the rockets, Starlink, and the capital base to fund it. The two companies needed each other. xAI was burning $2.5 billion in losses on $250 million in revenue. SpaceX was generating an estimated $8 billion in profit on $15 billion in revenue and needed an AI narrative to command the valuation it was targeting for its IPO.
What SpaceX has done, regardless of how the orbital AI vision ultimately plays out, is walk into a public market as something no company has been before: a rocket manufacturer, satellite internet provider, AI software company, social media platform, and supercomputer operator under one ticker. Whether that combination is worth $2 trillion depends entirely on which of those businesses you believe in most.
Tesla brought its innovative Cybercab robotaxi to the National Federation of the Blind (NFB) Annual Convention in Austin, Texas, on July 3 at the JW Marriott Austin.
The hands-on demonstration highlighted the vehicle’s thoughtful design for blind and visually impaired users, underscoring Tesla’s commitment to inclusive autonomous mobility. Attendees, many using white canes or accompanied by service dogs, experienced the steering-wheel-free Cybercab firsthand.

The showcase emphasized practical features tailored to the needs of the blind community. Braille lettering appears on physical controls, including door releases and emergency buttons, allowing users to navigate interfaces independently through touch. Generous interior space accommodates service animals and assistive devices such as canes, guide dogs, or mobility aids without compromising comfort.
Wheelchair-height seating facilitates easier transfers for users with additional mobility challenges. Photos from the event captured blind attendees approaching the vehicle confidently, service dogs relaxing inside, and hands exploring Braille-equipped handles.
Tesla Robotaxi’s official account detailed these elements, noting the Cybercab’s focus on accessibility, especially noting the Braille lettering and additional space for service animals.
How Tesla Will Transform Mobility for the Blind
Autonomous vehicles like the Cybercab promise revolutionary independence for the roughly 2.2 million visually impaired Americans. Traditional barriers—reliance on sighted drivers, costly paratransit, or limited public transit—often restrict spontaneous travel. Tesla Full Self-Driving aims to eliminate the need for a human operator, enabling on-demand, door-to-door rides via simple app hailing with voice guidance.
Users gain freedom to work, socialize, shop, or attend events anytime without scheduling hassles or safety concerns. This reduces isolation, boosts employment opportunities, and enhances quality of life, turning mobility from a dependency into true personal autonomy.
The NFB demonstration not only gathered valuable feedback but also generated excitement about a future where technology levels the playing field. By prioritizing inclusive design, Tesla advances a vision of transportation that serves everyone, potentially reshaping daily life for blind individuals and setting a standard for the autonomous industry.
As Cybercab deployment scales, these accessibility innovations could mark a significant step toward equitable mobility.

Tesla challenges startups to score a gig inside its most advanced European factory
Tesla is challenging startups to bring their best battery tech directly to Gigafactory Berlin.
Tesla has issued an open challenge to startups across Europe, inviting them to bring their best battery technology directly to the floor of Gigafactory Berlin. The program, called the JUNI x Tesla Battery Cell Giga Challenge, opened applications this month with a deadline of July 24, 2026, and is targeting startups with solutions that can make battery cell manufacturing faster, cheaper, safer, and more scalable at an industrial level.
The timing of the challenge is directly tied to Tesla’s most aggressive European battery investment yet. On May 12, 2026, Giga Berlin plant manager André Thierig announced a $250 million investment to scale the factory’s annual 4680 cell production capacity from 8 GWh to 18 GWh, more than doubling the previous target set just months earlier in December 2025. Thierig confirmed the expansion on X, saying the investment “will enable 18 GWh of annual 4680 cell production and create more than 1,500 new jobs.” Combined with a previously announced battery investment at the Grunheide site now approaches $1.2 billion.

The challenge is looking specifically for startups with proven solutions across five categories: materials, equipment, operations, automation, and artificial intelligence. Applications are screened directly by Tesla’s cell manufacturing team in Grunheide, and the strongest submissions move through technical discussions, a pitch day in front of Tesla stakeholders, and potentially a paid pilot project with the cell team. Tesla is not looking for ideas at concept stage. The program requires applicants to demonstrate working prototypes, test data, or prior pilots before being considered.
The historical context matters here. Elon Musk first announced plans for what he called the world’s largest battery cell production facility alongside the Giga Berlin car factory back in 2020, targeting up to 250 GWh of annual capacity. Those plans were shelved in 2022 when Tesla shifted its battery investment focus to the United States to take advantage of Inflation Reduction Act incentives. The revival of cell production at Giga Berlin, now backed by over $1 billion in committed capital, represents a return to an ambition that was set aside for three years. As Teslarati has reported, the 4680 format is central to Tesla’s long-term cost reduction strategy across vehicles, energy storage, including the Tesla Semi and Cybercab.
By opening the challenge to outside startups, Tesla is acknowledging that reaching 18 GWh at Grunheide will require technology it does not currently have in-house, and it is willing to pay for the right solutions. For a startup in the battery supply chain, a paid pilot with Tesla’s European cell team is as close to a direct commercial path as the industry offers.
