Tesla Semi original prototype surprises onlookers with stealthy silence while pulling trailer

The Tesla Semi has the potential to change the perception of large long-haulers, and a good part of this would be due to its low operating noise. Conventional diesel and gasoline-powered semis tend to be loud due to their large, roaring engines, making them quite disruptive for residents living close to their routes. The Semi, with its four Model 3-derived electric motors, boasts relatively minimal noise, as could be seen in sightings of the vehicle in the wild. 

This was something that some Tesla fans experienced while they were driving on what seems to be a freeway. As shared by Tesla owner @tesla_master on Twitter, what appears to be the company’s original silver Semi prototype was sighted pulling a trailer on the road. While the sighting itself is very brief and rife with typical social media antics, the video’s uploader did emphasize that the Semi was incredibly silent, to the point where the massive all-electric truck actually surprised them.

Sightings of the Tesla Semi in the wild would show that the Class 8 truck is not as silent as its smaller stablemates like the Model 3 and the Model Y, with the vehicle exhibiting an audible whine from its electric motors and tires when it accelerates. This sound, however, is far less disruptive than the roar and rumble of diesel and gasoline-powered semis that are currently being used today. 

Noise from traditional semi trucks has been a source of complaints across the United States over the years. In New Castle, Delaware, residents ended up clashing with the Delaware Department of Transportation over trucks that were reported to be loud, smelly, and noisy in 2018. In 2011, residents from High Bridge, New Jersey, complained explicitly about the noise caused by downshifting semi trucks. High Bridge officials then noted that the noises caused by the trucks were so disruptive that the vehicles could be heard around the town.

These are issues that would be addressed, at least in part, by vehicles like the Tesla Semi, especially considering that the all-electric Class 8 truck does not require downshifting. This makes the Tesla Semi relatively quiet to operate, a characteristic that residents in the vehicle’s routes would most likely appreciate.

Tesla has released an epic year-in-review video for 2025, recapping some of its major achievements from refreshed models to autonomy breakthroughs and production ramps. 

The cinematic montage, posted by the official Tesla account on X, celebrated the company’s progress in EVs, energy, and Robotaxi development while looking ahead to an even bigger 2026.

Tesla’s 2025 highlights recap

Tesla has had a busy 2025, as highlighted in the recap video. The video opened with Elon Musk explaining the company’s pursuit of sustainable abundance. A number of milestones were then highlighted, such as the rollout of FSD v14, Optimus’ numerous demos, the opening of the Tesla Diner in Hollywood, LA, the completion of the world’s first autonomous car delivery, and the launch of the Robotaxi network in Austin and the San Francisco Bay Area.

Tesla also highlighted several of its accomplishments over the year. As per the company, the Model Y was the year’s best-selling vehicle globally again, and Teslas became more affordable than ever thanks to the Model 3 and Model Y Standard. Other key models were also rolled out, such as the refreshed Model S and X, as well as the new Model Y, the new Model Y Performance, and the six-seat, extended wheelbase Model Y L. 

The Megablock was also unveiled during the year, and the Supercharger Network grew by 18%. Over 1 million Powerwalls were also installed during the year, and the Cybertruck became the first EV truck to get both an IIHS Top Safety Pick+ award and an NHTSA 5-Star safety rating.

Cybercab production confirmed

Interestingly enough, Tesla also confirmed in its 2025 recap video that the production of the Cybercab has started. This bodes well for the vehicle, as it could result in the vehicle really being mass-produced in the first half of 2026. Elon Musk confirmed during the 2025 Annual Shareholder Meeting that Cybercab production should earnestly start around April 2026

Musk has also noted that the Cybercab will be Tesla’s highest-volume vehicle yet, with the company aiming for an annual production rate of about 2 million units. “If you’ve seen the design of the Cybercab line, it doesn’t look like a normal car manufacturing line,” Musk said earlier this year. “It looks like a really high-speed consumer electronics line. In fact, the line will move so fast that actually people can’t even get close to it.”

Even before entering production, Tesla’s Cybercab is already transforming the appearance of Austin’s streets, with multiple prototypes spotted testing in downtown areas recently. 

Videos and photos showed the sleek, two-seat autonomous vehicles navigating traffic. Interestingly enough, the vehicles were equipped with temporary steering wheels and human safety drivers.

Recent Cybercab sightings

Over the weekend, enthusiasts captured footage of two Cybercabs driving together in central Austin, their futuristic silhouettes standing out amid regular traffic. While the vehicles featured temporary steering wheels and side mirrors for now, they retained their futuristic, production-intent exterior design.

Industry watcher Sawyer Merritt shared one of the vehicles’ videos, noting the increasing frequency of the autonomous two-seater’s sightings.

Previewing the autonomous future

Sightings of the Cybercab have been ramping in several key areas across the United States in recent weeks. Sightings include units at Apple’s Visitor Center in California, the Fremont factory test track, and in Austin’s streets.

The increased activity suggests that Tesla is in overdrive, validating the autonomous two-seater ahead of its planned volume production. Elon Musk confirmed at the 2025 Shareholder Meeting that manufacturing begins around April 2026 with ambitious targets, and during an All-Hands meeting earlier this year, Musk hinted that ultimately, Tesla’s factories should be able to produce one Cybercab every 10 seconds.

Tesla has achieved a new milestone, rolling out its nine millionth vehicle worldwide from Giga Shanghai. 

The achievement, announced by Tesla Asia on X, celebrated not just the Shanghai team’s output but the company’s cumulative production across all its factories worldwide. The milestone came as 2025 drew to a close, and it inspired praise from some of the company’s key executives.

Tesla’s 9 million vehicle milestone

The commemorative photo from Tesla Asia featured the Giga Shanghai team assembled on the factory floor, surrounding the milestone Model Y unit, which looked pristine in white. The image was captioned: “Our 9 millionth vehicle globally has just rolled off the production line at Giga Shanghai. Thanks to our owners and supporters around the world.” 

Senior Vice President of Automotive Tom Zhu praised Tesla’s factory teams for the remarkable milestone. He also shared his gratitude to Tesla owners for their support. “Congrats to all Tesla factories for this amazing milestone! Thanks to our owners for your continued support!” Zhu wrote in a post on X.

Giga Shanghai’s legacy

Tesla’s nine million vehicle milestone is especially impressive considering that just 207 days ago, the company announced that it had built its eight millionth car globally. The eight millionth Tesla, a red Model Y, was built in Giga Berlin. The fact that Tesla was able to build a million cars in less than seven months is quite an accomplishment.

Giga Shanghai, Tesla’s largest factory by volume, has been instrumental to the company’s overall operations, having reached four million cumulative vehicles earlier in 2025. The plant produces Model 3 and Model Y for both domestic Chinese and export markets, making it the company’s primary vehicle export hub.
