Tesla Semi’s temporary ‘Megacharger’ system glimpsed in Madonna Inn sighting
More than a year since unveiling the vehicle, Tesla continues to conduct real-world tests of the Semi across the United States. In its recent sighting, the Semi was spotted while it was charging at the iconic and quirky Madonna Inn, located at San Luis Obispo, CA. This time around, the sighting provided what could very well be the first glimpse at Tesla’s temporary “Megacharger” solution for the Semi test mule.
When Elon Musk unveiled the Tesla Semi, he noted that the vehicle would be supported by a network of “Megachargers,” which are capable of replenishing 400 miles of range in as little as 30 minutes of charging. Unlike the Supercharger Network, which has a power output of roughly 120 kW, speculations are high that Tesla’s Megacharger will see around ten times the power levels. During the vehicle’s unveiling, an image was taken of the long-hauler’s charging port, revealing an 8-pin configuration that’s noticeably larger than the Supercharger ports found on the Model S, X, and 3.
Tesla’s Megacharger Network is yet to be built, though some reservation holders of the long-hauler are already installing dedicated charging stations for the Semi in some of their key facilities. Considering that the Semi test mule is currently conducting real-world tests across the United States, though, Tesla has been utilizing a temporary charging solution for the vehicle using its existing Supercharger Network. That said, the electric car maker has been notably secretive about the Semi prototype’s temporary “Megacharger” system. That is, until recently.

During the vehicle’s recent sighting at Madonna Inn, a part of the Semi’s charger was photographed and shared online by auto enthusiast jerryswhip on Instagram. A member of the r/TeslaMotors subreddit who was present at the Semi’s sighting, u/Jace11, further noted that the long-hauler was connected to a hub that was, in turn, linked to three Supercharger stations. This hub seems to be visible in one of the images taken of the vehicle, as a contraption with a red light could be seen in the area beside the Semi’s charging port.
Following its charging session at the Madonna Inn Supercharger, the Semi headed back into the highway towards San Francisco. Footage taken by Tesla enthusiast Steven M. Conroy showcased the Semi’s impressive speed once more, while capturing the vehicle’s unique, unearthly sound as it accelerated on the freeway. At several points in the video, the now-iconic futuristic whine of the vehicle’s four Model 3-derived electric motors was clearly audible.

Being a vehicle designed to compete in the trucking industry, the Semi has the potential to be the most disruptive offering from Tesla. The vehicle, after all, has several features that make it a viable alternative to diesel-powered semi-trailers, from its four Model 3-derived electric motors, its comparable Class 8 hauling capacity, to its superior speed. In true Tesla fashion, the company continues to develop and improve the Semi, with President of Automotive Jerome Guillen stating that the all-electric truck has been given notable improvements since it was unveiled last year. Some of the Semi’s improvements have been teased by Elon Musk earlier this year as well, with the CEO stating that the long-range variant of the vehicle would have closer to 600 miles of range per charge.
The Tesla Semi has attracted a notable amount of support from several high-profile companies, including PepsiCo, JB Hunt, UPS, and FedEx, to name a few. Even foreign companies such as ASKO in Norway and Bee’ah in the Middle East have also placed orders for the electric long-hauler. Tesla is yet to announce where the Semi would be manufactured, though the company is expected to start producing the vehicle sometime in 2019.

Tesla Board Chair discusses what is being done to protect CEO Elon Musk

Tesla Board Chair Robyn Denholm met with Bloomberg this morning to discuss a variety of topics, but perhaps one of the most interesting was her comments on what is being done to protect company CEO Elon Musk.
After the assassination of right-wing political commentator Charlie Kirk this week, there have been concerns about Musk’s safety, as well as that of other high-profile business leaders and political figures.
Earlier this week, Musk said himself that his security detail would be increased significantly following Kirk’s death, a move that many investors and fans of the company had requested because of political violence.
Elon Musk assures Tesla investors he will enhance his security detail
“Definitely need to enhance security,” Musk said. Tesla spent $3.3 million on Musk’s security in 2024 and January and February 2025. For reference, Meta spent over $27 million on Mark Zuckerberg’s security last year, which is higher than any other tech CEO.
During Denholm’s appearance on Bloomberg TV earlier today, she stated that the company has been focused on Musk’s security detail for “many years,” especially considering he is one of the richest people on Earth and holds an incredible amount of influence.
“It is something that we take very seriously; he takes it very seriously as well. So, again, from a board perspective, it is something we’ve discussed at length,” Denholm said.

Denholm added that she believes “there is not anyone in a boardroom that is not touched by what has happened with Charlie Kirk.”
Although Musk’s political involvement has toned down significantly in the past, he still has enemies, especially based on groups that oppose him and the company specifically. Based on this week’s events, it feels that increased security is a necessary expense Tesla must account for.

Tesla bear turns bullish for two reasons as stock continues boost
“I think from a trading perspective, it looks very interesting,” Nathan said, citing numerous signs of strength, such as holding its 200-day moving average and holding against its resistance level.

A Tesla bear is changing his tune, turning bullish for two reasons as the company’s stock has continued to get a boost over the past month.
Dan Nathan, a notorious skeptic of Tesla shares, said he is changing his tune, at least in the short term, on the company’s stock because of “technicals and sentiment,” believing the company is on track for a strong Q3, but also an investment story that will slowly veer away from its automotive business.
“I think from a trading perspective, it looks very interesting,” Nathan said, citing numerous signs of strength, such as holding its 200-day moving average and holding against its resistance level.
He also said he believes a rally for the stock could continue as it heads into the end of the quarter, especially as the $7,500 electric vehicle tax credit is coming to an end at the end of the month.
With that being said, he believes the consensus for Q3 deliveries is “probably low,” as he believes Wall Street is likely underestimating what Tesla will bring to the table on October 1 or 2 when it reports numbers for the quarter.

Tesla shares are already up over five percent today, with gains exceeding nine percent over the past five trading days, and more than fourteen percent in the past month.
While some analysts are looking at the performance of other Mag 7 stocks, movement on rates from the Federal Reserve, and other broader market factors as reasoning for Tesla’s strong performance, it appears some movement could be related to the company’s recent developments instead.
Over the past week, Tesla has made some strides in its Robotaxi program, including a new license to test the platform in the State of Nevada, which we reported on.
Tesla lands regulatory green light for Robotaxi testing in new state
Additionally, the company is riding the tails of the end of the EV tax credit, as inventory, both new and used, is running extremely low, generally speaking. Many markets do not have any vehicles to purchase as of right now, making delivery by September 30 extremely difficult.
However, there has been some adjustments to the guidelines by the IRS, which can be read here:
Tesla is trading at around $389 at 10:56 a.m. on the East Coast.

Tesla lands regulatory green light for Robotaxi testing in new state
This will be the third state in total where Tesla is operating Robotaxi, following Austin and California.

Tesla has landed a regulatory green light to test its Robotaxi platform in a new state, less than three months after the ride-hailing service launched in Texas.
Tesla first launched its driverless Robotaxi suite in Austin, Texas, back on June 22. Initially offering rides to a small group of people, Tesla kept things limited, but this was not to be the mentality for very long.
It continued to expand the rider population, the service area, and the vehicle fleet in Austin.
The company also launched rides in the Bay Area, but it does use a person in the driver’s seat to maintain safety. In Austin, the “Safety Monitor” is present in the passenger’s seat during local rides, and in the driver’s seat for routes that involve highway driving.
Tesla is currently testing the Robotaxi platform in other states. We reported that it was testing in Tempe, Arizona, as validation vehicles are traveling around the city in preparation for Robotaxi.
Tesla looks to make a big splash with Robotaxi in a new market
Tesla is also hoping to launch in Florida and New York, as job postings have shown the company’s intention to operate there.
However, it appears it will launch in Nevada before those states, as the company submitted its application to obtain a Testing Registry certification on September 3. It was processed by the state’s Department of Motor Vehicles Office of Business Licensing on September 10.
NEWS: Tesla has officially received approval from the Nevada DMV to start testing autonomous vehicles (robotaxis) on public roads.

It will then need to self-certify for operations, essentially meaning they will need to comply with various state requirements.
This will be the third state in total where Tesla is operating Robotaxi, following Austin and California.
CEO Elon Musk has stated that he believes Robotaxi will be available to at least half of the U.S. population by the end of the year. Geographically, Tesla will need to make incredible strides over the final four months of the year to achieve this.
