Just recently, Tesla CEO Elon Musk announced that the Tesla Semi has been able to complete a 500-mile trip while weighing in at 81,000 pounds. The announcement was received with much excitement from the electric vehicle community, though questions still remained about the unladen weight of the Semi without its trailer and cargo.
As noted in a post from JD Power, the unladen weight of a conventional semi truck without a trailer can vary between 10,000 and 25,000 pounds. Considering that a typical 53-foot trailer weighs about 10,000 pounds, conventional semi trucks usually have a total unladen weight of about 35,000 pounds when hooked up to an empty trailer.
Following Musk’s announcement on Twitter, images of the Tesla Semi seemingly taken near the vehicle’s production facility in Nevada emerged online. One of these images showed a production Tesla Semi pulling a trailer loaded with 11 Jersey barriers. Tesla enthusiasts have speculated that the Semi loaded with the Jersey barriers was likely the vehicle that accomplished the 500-mile feat.
As noted by Paul Lackey, an engineer at the electric drive company EVDrive and the person behind Twitter’s “Nikola Insider” whistleblower account, Jersey barriers typically weigh about 4,000 pounds each. If these estimates are accurate, it would suggest that the Semi was pulling a load of about 44,000 pounds during its 500-mile trip. If one were to consider the weight of the empty 53-foot trailer and Musk’s 81,000-pound total weight comment, it would suggest that the Tesla Semi weighs about 27,000 pounds on its own.
If these estimates are somewhat accurate and the Semi does weigh around 27,000 pounds by itself, it would unsurprisingly be heavier than its ICE-powered counterparts, but not by much. Compared to a diesel-powered tractor trailer that weighs about 20,000 pounds, the Semi would end up carrying about 7,000 pounds less cargo. The Semi, however, has better performance and less maintenance than its conventional rivals in the trucking market.
The Tesla Semi’s weight has been a point of criticism for the vehicle, with skeptics such as Microsoft co-founder Bill Gates previously noting that all-electric Class 8 trucks are not practical because they would be far too heavy. But while Class 8 all-electric trucks like the Semi are indeed equipped with very heavy batteries, they also do not have massive, heavy diesel engines and large transmissions. The absence of these components, as well as Tesla’s constant innovation with its electric motors and batteries, appears to have made the Semi’s weight quite competitive in the trucking market.

Tesla gets new information request from NHTSA on Robotaxi rollout
Tesla has been contacted by the NHTSA regarding plans for the Robotaxi rollout and how it will handle poor weather.

Tesla has been contacted by the National Highway Traffic Safety Administration (NHTSA) regarding its planned rollout of a Robotaxi platform in Austin, Texas.
The agency sent a letter to Tesla Field Quality Director Eddit Gates, seeking more information on exactly how the company plans to operate the fleet in poor weather conditions. The NHTSA wants to know how Tesla’s technology and operational use cases will “assess the ability of Tesla’s system to react appropriately to reduced roadway visibility conditions.”
Additionally, the NHTSA said it would like additional information on Tesla’s development of technologies for use in ‘robotaxi’ vehicles to understand how Tesla plans to evaluate its vehicles and driving automation technologies for public roads.
Tesla has already started operating a supervised version of the Robotaxi platform for employees in both Austin and San Francisco. This limited rollout has completed thousands of rides already, but differs from the version it plans to roll out in the coming weeks in Austin, as it currently has a driver sitting in the driver’s seat.
Tesla says it has launched ride-hailing Robotaxi teaser to employees only
They are there to supervise the vehicle and ensure safety early on in the program.
The letter that was sent to Tesla on May 8 is part of a greater investigation that was opened by the NHTSA on October 17, titled “FSD Collisions in Reduced Roadway Visibility Conditions.”
The agency said the purpose of the “Preliminary Evaluation of FSD” was to assess:
- The ability of FSD’s engineering controls to detect and respond appropriately to reduced roadway visibility conditions;
- Whether any other similar FSD crashes have occurred in reduced roadway visibility conditions and, if so, the contributing circumstances for those crashes; and
- Any updates or modifications from Tesla to the FSD system that may affect the performance of FSD in reduced roadway visibility conditions. In particular, this review will assess the timing, purpose, and capabilities of any such updates, as well as Tesla’s assessment of their safety impact.
Tesla is required to respond to the NHTSA’s request by June 19.

Potential affordable Tesla “Model 2/Model Q” test car spotted anew in Giga Texas
The recent footage featured an apparent test car that looks very similar to a vehicle that was spotted in the Fremont Factory last month.

Tesla has been very secretive about the “more affordable models” that it intends to start producing in the first half of 2025, but the company does seem to be quite busy testing something interesting in the Giga Texas complex. This was, at least, as per recent aerial footage from a longtime Giga Texas watcher.
The recent footage featured an apparent test car that looks very similar to a vehicle that was spotted in the Fremont Factory last month.
New Giga Texas Sighting
In a post on X, longtime Giga Texas watcher and drone operator Joe Tegtmeyer noted that he recently spotted a rather unique test car in the factory complex. The vehicle was under a car cover, but it was evidently missing its body panels and roof. Interestingly enough, it seemed to be shaped like a Model Y (it even had Model Y wheels), though it looked a bit more compact than another Model Y that was parked next to it.
Interestingly enough, a rather similar test car was spotted at another Tesla plant, the Fremont Factory in California, last month. Tesla watcher Met God in Wilderness, who has been posting aerial videos of the Fremont Factory for years, shared some footage from a drone flyover in mid-April. One of the vehicles captured in the flyover was an apparent test car that was parked next to fully-built Model Y and Model S vehicles. The test car in this sighting also looked like a compact crossover, and it was also missing its roof and body panels.
Tesla’s Affordable Cars
In the Q1 2025 Update Letter, Tesla noted that “plans for new vehicles, including more affordable models, remain on track for start of production in the first half of 2025.” In the Q1 earnings call, Tesla VP of Vehicle Engineering Lars Moravy stated that Tesla’s affordable cars would resemble the company’s existing vehicles, though they will be more affordable.
These comments suggested that Tesla’s affordable cars, which have been informally dubbed by the EV community as the “Model 2 or Model Q,” will look a lot like its two mass market vehicles, the Model 3 sedan and the Model Y crossover. “Models that come out in the next months will be built on our lines and will resemble, in form and shape, the cars we currently make. And the key is that they’ll be affordable, and you’ll be able to buy one,” Moray stated.

Elon Musk invited to attend investment summit in Saudi Arabia: report
Musk’s reported invitation comes on the sidelines of United States President Donald Trump’s visit to the Middle East.

A planning note reported viewed by Reuters has indicated that Tesla CEO Elon Musk has been invited to a Saudi-U.S. investment forum in Riyadh, the capital of Saudi Arabia. The event is expected to be held on Tuesday.
Musk’s reported invitation comes on the sidelines of United States President Donald Trump’s visit to the Middle East.
Musk’s Invitation
As per Reuters, the upcoming investment forum is expected to be attended by some of the most distinguished people in the investment world. These include the CEOs of high-profile companies such as Blackrock, Citigroup, IBM, Boeing, Delta Airlines, American Airlines, and United Airlines, among others, the publication noted.
Considering the other attendees of the event, Elon Musk would likely fit right thanks to his leadership of companies like Tesla, SpaceX, and xAI, as well as his close ties with the Trump administration through his work at the Department of Government Efficiency (DOGE).
Musk and Saudi Arabia
Elon Musk’s relationship with Riyadh have notably improved since the start of Trump’s second term as United States president. Highlighting this improvement was Tesla’s launch in Saudi, which was held in April. Tesla’s launch was a notable event based on videos posted of the occasion, with the company showcasing some of its most exciting products, including Optimus, the Cybertruck, and the Cybercab, its self-driving robotaxi.
Tesla’s launch in Saudi Arabia, as well as his reported invitation to the upcoming investment forum, suggests that the CEO’s feud with Yasir Al Rumayyan, head of the $925 billion Public Investment Fund, has ended. The PIF Head was among the people involved in Elon Musk’s infamous “funding secured” tweet in 2018, which resulted in hefty fines and his removal as Tesla’s Board Chair. The PIF also sold its Tesla holdings and invested in another EV company, Lucid Group Inc.
