Just like all of Tesla’s other offerings, the Semi is a very quick vehicle. Prior to the truck’s unveiling, Elon Musk noted in a TED Talk that the Semi would be a “very spry” truck that could be driven around like sports car.

Musk’s comments were eventually highlighted by the Semi’s specs, such as its 0-60 mph time of 5 seconds flat when launching without a trailer, as well as actual sightings of the vehicle accelerating like a high-performance sedan. Earlier this year, for one, the Semi was spotted performing a seemingly impromptu tire-shredding acceleration run while cruising on an area between Tesla’s Fremont factory and its Palo Alto headquarters.

The Semi has since been sighted in multiple states across the US, and during the company’s Q2 2018 earnings call, Jerome Guillen, the former head of Tesla’s truck programs who is now serving as the company’s President of Automotive, pointed out that the vehicle had already been improved since it was initially unveiled. The exact nature of these improvements remains to be seen, but if a video of the Semi captured earlier this month is any indication, it appears that the electric long-hauler has gotten even more daunting and impressive when it performs a full-speed acceleration run.

The Tesla Semi was sighted in Salt Lake City earlier this month, and not long after that, the truck visited the company’s office in Draper, UT. The vehicle attracted the attention of members of the Tesla community, including r/TeslaMotors subreddit member u/m3gusta_, who was able to capture the vehicle on video as it accelerated forward while hauling a trailer. The video was brief, but it was enough to show what the Semi looks and sounds like when it is launching with what seemed like the vehicle’s full power. Needless to say, the Tesla Semi’s quickness, as well as the unmistakable, high-pitched, futuristic sound of the truck’s four Model 3-derived electric motors, were nothing short of unearthly.

The Semi’s performance, handling, and power were specifically pointed out by professional driver Emile Bouret, a close friend of Tesla chief designer Franz von Holzhausen, in an Instagram post earlier this month. Bouret, who is no stranger to the power and performance of Tesla’s electric cars due to his work since the original Tesla Roadster (he also conducted the test drives in the next-gen Roadster during the Semi’s unveiling last year), noted that the Semi’s “speed and agility” were at odds with a vehicle of its size. Bouret further dubbed the electric long-hauler as a truck that is cool and crazy in equal measure.

Over the past month, sightings of the Semi have increased, with the vehicle being spotted traveling across several states and visiting some of its reservation holders like J.B. Hunt, UPS, and Ruan Transportation Management Systems. Tesla’s engineers accompanying the vehicle as it conducted its real-world tests have also begun sharing information about the truck to the Tesla community. During a stop in CO, for example, Tesla engineers shared details on the Semi’s upcoming sleeper cabin, the prototype’s carbon fiber construction, and the truck’s existing 26-camera system.

When the vehicle was unveiled last year, CEO Elon Musk noted that the Tesla Semi is expected to begin production sometime in 2019. As noted by Eric Markowitz & Dan Crowley of Worm Capital in a note published after a tour of Gigafactory 1, Tesla is planning on “earnestly” producing the Semi by 2020.

Watch the Tesla Semi launch with a trailer in the video below. Do note that this video is best viewed with the sound turned up.

Tesla’s new Model S and X spotted, but they leave a lot to be desired

The Model S and Model X testing mules spotted by The Kilowatts have few minor visual changes.

Tesla has been hinting for a few months now that the flagship Model S and Model X would be getting some attention in 2025 as the vehicles continue to be sold in extremely low volumes.

Both models seem to be under the knife, especially as their newest versions were spotted in California earlier this week.

However, images of the vehicles seem to show that Tesla is not planning a major overhaul, which begs the question: why even do it in the first place?

Tesla makes a decision on the future of its flagship Model S and Model X

The Model S and Model X are grouped with the Cybertruck in Tesla’s quarterly delivery releases, and Q1 saw just 12,881 units of the three cars delivered. The Cybertruck likely made up the majority of this number, as some outlets reported around 6,400 deliveries of the all-electric pickup in Q1.

This is unconfirmed.

The Model S and Model X have stuck around for “sentimental reasons,” according to CEO Elon Musk, who said back in 2021:

“I mean, they’re very expensive, made in low volume. To be totally frank, we’re continuing to make them more for sentimental reasons than anything else. They’re really of minor importance to the future.”

However, the cars seem to be in need of a serious refresh. As Tesla changed up the exterior aesthetic on both the Model 3 and Model Y, recent images captured of the Model X by The Kilowatts seem to show this is not the strategy with the Model X or Model S:

As we can see, the overall aesthetic of the X, if this is what Tesla plans to release, has literally no changes from a purely visual standpoint. There is the addition of the front bumper camera, which was first implemented on the Cybercab unveiled in October 2024, and then on the new Model Y this year.

There are some new 20″ wheels, and the interior has been fitted with ambient lighting.

The Model S looked to be relatively the same, other than these few hardware changes, including a rear diffuser on this Plaid that was spotted:

While these changes are welcome and should be beneficial, they don’t seem like they will encourage major sales growth, which might be something Tesla is okay with.

Admitting the two cars are low volume and not contributors to the company’s long-term goals, Musk is likely willing to just upgrade things to make these more compatible and better functioning with the Full Self-Driving suite.

Earlier this year, VP of Vehicle Engineering Lars Moravy said the S and X were not going anywhere and would get “some love” before the end of 2025:

“Just give it a minute. We’ll get there. The upgrade a couple of years ago was bigger than most people thought in terms of architecture and structure of the car got a lot better, too. But, we’ll give it some love later this year and make sure it gets a little bit…you know, with the stuff we’ve been putting in 3 and Y. Obviously, with 3 and Y, the higher volume stuff, you’ve gotta focus there.”

It seems these strategies have held true — the S and X appear to be getting what the 3 and Y got with the ambient lighting and front bumper camera (at least on the Model Y).

Tesla set for ‘golden age of autonomous’ as Robotaxi nears, ‘dark chapter’ ends: Wedbush

Tesla is set to win big from the launch of the Robotaxi platform, Wedbush’s Dan Ives said.

Tesla (NASDAQ: TSLA) is set to kick off its own “golden age of autonomous growth” as its Robotaxi platform nears launch and a “dark chapter” for the company has evidently come to a close, according to Wedbush analyst Dan Ives.

Ives has jostled his price target on Tesla shares a few times already this year, usually switching things up as the market sways and the company’s near-term outlook changes. His price target on Tesla has gone from $550 to $315 to $350 back to $500 this year, with the newest adjustment coming from a note released early on Friday.

As CEO Elon Musk has essentially started to dwindle down his commitment to the Department of Government Efficiency (DOGE) altogether, Ives believes that Tesla’s “dark chapter” has come to a close:

“First lets address the elephant in the room…2025 started off as a dark chapter for Musk and Tesla as Elon’s role in the Trump Administration and DOGE created a life of its own which created brand damage and a black cloud over the story….but importantly those days are in the rear-view mirror as we are now seeing a recommitted Musk leading Tesla as CEO into this autonomous and robotics future ahead with his days in the White House now essentially over.”

Ives believes Tesla’s launch of Robotaxi should be the company’s way to unlock at least $1 trillion in value alone, especially as the Trump White House will fast-track the key initiatives the automaker needs to get things moving in the right direction:

“The $1 trillion of AI valuation will start to get unlocked in the Tesla story and we believe the march to a $2 trillion valuation for TSLA over the next 12 to 18 months has now begun in our view with FSD and autonomous penetration of Tesla’s installed base and the acceleration of Cybercab in the US representing the golden goose.”

There are some concerns moving forward, but none of which relate to the AI/autonomous play that Ives primarily focuses on within the Friday note. Instead, they are related to demand in both Europe and Asia, as Ives said, “there is still wood to chop to turn around Model Y growth” in both of those markets.

Nevertheless, the big focus for Ives is evidently the launch of Robotaxi and the potential of the entire autonomous division that Tesla plans to offer as a ride-sharing service in the coming months. Ives also believes a 50 percent or more penetration of Full Self-Driving could totally transform the financial model and margins of Tesla moving ahead.

Aware of the setbacks Tesla could encounter, Ives still believes that Tesla will establish itself as “the true autonomous winner over” and that investors will recognize the AI vision the company has been so bullish on.

Ives pushed his price target to $500. Tesla shares are down just under 1% at the time of publication. They are trading at $337.88 at 11:45 on the East Coast.

SpaceX Starship gets FAA nod for ninth test flight

The FAA has given the green light for Starship’s ninth test flight.

SpaceX has received FAA approval for the ninth test flight of the Starship rocket. The approval was delayed due to the federal agency finishing its comprehensive safety review of the eighth flight earlier this year.

The FAA said in a statement that it has determined that SpaceX has “satisfactorily addressed the causes of the mishap, and therefore, the Starship vehicle can return to flight.”

The eighth test flight occurred back on March 6. SpaceX completed a successful liftoff of Starship and the Super Heavy Booster, before the two entered stage separation a few minutes after launch.

Starship Flight 8: SpaceX nails Super Heavy booster catch but loses upper stage

The booster returned and was caught by the chopsticks on the launch pad, completing the second successful booster catch in the program’s history. However, SpaceX lost contact with Starship in the upper atmosphere.

The ship broke up and reentered the atmosphere over Florida and the Bahamas.

The debris situation caused the FAA to initiate a mishap investigation:

The FAA said it will verify that SpaceX implements all the corrective actions on Flight 9 that it discovered during the mishap investigation.

There is no current confirmed launch window, but the earliest it could take off from Starbase is Tuesday, May 27, at 6:30 p.m. local time.

To prevent any injuries and potentially limit any damage, the FAA has stayed in contact with various countries that could be impacted if another loss of vehicle occurs:

“The FAA is in close contact and collaboration with the United Kingdom, Turks & Caicos Islands, Bahamas, Mexico, and Cuba as the agency continues to monitor SpaceX’s compliance with all public safety and other regulatory requirements.”

The agency has also stated that the Aircraft Hazard Area (AHA) is approximately 1,600 nautical miles and extends eastward from the Starbase, Texas, launch site through the Straits of Florida, including the Bahamas and Turks & Caicos.

For flight 8, the AHA was just 885 nautical miles.
