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 puts Giga Berlin in Plaid Mode with new massive investment

The facility, Tesla’s first in Europe, opened in 2022 and has become a cornerstone for Model Y production and, increasingly, in-house battery manufacturing. Recent announcements highlight a dual focus on scaling vehicle output and advancing vertical integration through 4680 battery cells.

Tesla is pushing forward with significant upgrades at its Gigafactory Berlin-Brandenburg in Grünheide, Germany, signaling renewed confidence in its European operations despite past market challenges.

The facility, Tesla’s first in Europe, opened in 2022 and has become a cornerstone for Model Y production and, increasingly, in-house battery manufacturing. Recent announcements highlight a dual focus on scaling vehicle output and advancing vertical integration through 4680 battery cells.

In April, plant manager André Thierig announced a 20 percent increase in Model Y production starting in July, following a record Q1 output of more than 61,000 vehicles. To support the ramp-up, Tesla plans to hire approximately 1,000 new employees beginning in May and convert 500 temporary workers to permanent positions.

The move is expected to lift weekly production significantly, addressing rebounding demand in Europe after a challenging 2025.

The expansion builds on earlier progress. In 2025, Tesla secured partial approvals to add roughly 2 million square feet of factory space, raising potential annual vehicle capacity from around 500,000 toward 800,000 units, with longer-term ambitions approaching one million vehicles per year. Logistical improvements, new infrastructure, and battery-related facilities are already underway on company-owned land.

Battery production is the latest major focus. On May 12, Thierig revealed an additional $250 million investment in the on-site cell factory. This more than doubles the planned 4680 battery cell capacity to 18 gigawatt-hours annually—up from the 8 GWh target set in December 2025—while creating over 1,500 new battery-related jobs.

Total cell investments at the site now exceed previous figures, bringing the factory closer to full vertical integration: cells, packs, and vehicles produced under one roof. Tesla describes this as unique in Europe and a step toward stronger supply chain resilience.

The plans come amid regulatory and community hurdles. Earlier expansion proposals faced protests over environmental concerns and water usage, leading to phased approvals beginning in 2024. Tesla has navigated these by emphasizing sustainable practices and economic benefits, including thousands of local jobs in Brandenburg.

With nearly 12,000 employees already on site and production steadily climbing, Gigafactory Berlin is poised for growth. The combined vehicle and battery expansions position the plant as a key hub for Tesla’s European ambitions, potentially making it one of the continent’s largest manufacturing complexes if local support continues.

As EV demand recovers, these investments underscore Tesla’s commitment to scaling efficiently in Germany while addressing regional supply chain needs.

Honda gives up on all-EV future: ‘Not realistic’

Mibe believes the demand for its gas vehicles is certainly strong enough and has changed “beyond expectations.” As many drivers went for EVs a few years back, hybrids are becoming more popular for consumers as they offer the best of both worlds.

Honda has given up on a previous plan to completely changeover to EVs by 2040, a new report states. The company’s CEO, Toshihiro Mibe, said that the idea is “not realistic.”

Mibe believes the demand for its gas vehicles is certainly strong enough and has changed “beyond expectations.” As many drivers went for EVs a few years back, hybrids are becoming more popular for consumers as they offer the best of both worlds.

Mibe said (via Motor1):

“Because of the uncertainty in the business environment and also the customer demand, is changing beyond our expectation and, therefore, we have judged that it’ll be difficult to achieve. That ratio [100-percent electric in 2040] is not realistic as of now. We have withdrawn this target.”

Instead of going all-electric, Honda still wants to oblige by its hopes to be net carbon neutral by 2050. It will do this by focusing on those popular hybrid powertrains, planning to launch 15 of them by March 2030.

Honda will invest 4.4 trillion yen, or almost $28 billion, to build hybrid powertrains built around four and six-cylinder gas engines.

There are so many companies abandoning their all-electric ambitions or even slowing their roll on building them so quickly. Ford, General Motors, Mercedes, and Nissan have all retreated from aggressive EV targets by either cancelling, delaying, or pausing the development of electric models.

Early-decade pledges from multiple brands proved overly ambitious as infrastructure lags, battery costs remain high in some markets, and many buyers prefer hybrids for their convenience and range. Toyota has long championed hybrids, while others have quietly extended internal-combustion timelines.

For Honda—historically known for reliable gasoline engines—this shift leverages its core strengths while buying time to refine electric technology. Whether the hybrid-heavy strategy will protect market share in an increasingly competitive landscape remains to be seen, but one thing is clear: the gas engine is far from dead at Honda, unfortunately.

Delta Airlines rejects Starlink, and the reason will probably shock you

In a pointed exchange on X, Elon Musk defended SpaceX’s uncompromising approach to Starlink’s in-flight internet service, explaining why Delta Air Lines walked away from a deal.

Delta Airlines Airbus photographed April 2024 Delta-owned. No expiration date, unrestricted use.

SpaceX frontman Elon Musk explained on Wednesday why commercial airline Delta got cold feet over offering Starlink for stable internet on its flights — and the reason will probably shock you.

In a pointed exchange on X, Elon Musk defended SpaceX’s uncompromising approach to Starlink’s in-flight internet service, explaining why Delta Air Lines walked away from a deal.

Delta rejected Starlink because it insisted on routing all connectivity through its branded “Delta Sync” portal rather than allowing a simple Starlink experience.

Instead, the airline partnered with Amazon’s Project Kuiper—rebranded as Amazon Leo—for high-speed Wi-Fi on up to 500 aircraft, with rollout targeted for 2028. At the time of the announcement, Kuiper had roughly 300 satellites in orbit, while Starlink operated more than 10,400.

The use of the “Delta Sync” portal would not work for SpaceX, as Musk went on to say that:

“SpaceX requires that there be no annoying ‘portal’ to use Starlink. Starlink WiFi must just work effortlessly every time, as though you were at home. Delta wanted to make it painful, difficult and expensive for their customers. Hard to see how that is a winning strategy.”

Musk doubled down in a follow-up post:

“Yes, SpaceX deliberately accepted lower revenue deals with airlines in exchange for making Starlink super easy to use and available to all passengers.”

SpaceX has structured its airline agreements to prioritize zero-friction access—no captive portals, no SkyMiles logins, no paywalls or ads blocking basic connectivity.

While this means forgoing higher-margin deals that would let carriers monetize the service more aggressively, it ensures Starlink feels like home broadband at 35,000 feet. Passengers on partner airlines such as United, Qatar Airways, and Air France have already praised the service for enabling seamless video calls, streaming, and work mid-flight without interruptions.

Delta’s choice reflects a different philosophy. By keeping Wi-Fi behind its Delta Sync ecosystem, the airline aims to drive loyalty program engagement and control the digital passenger journey. Yet, critics argue this short-term control comes at the expense of immediate competitiveness.

Airlines already installing Starlink are pulling ahead in customer satisfaction surveys, while Delta passengers face years of reliance on slower, legacy systems until Leo launches.

SpaceX’s decision to trade revenue for simplicity will pay off in the longer term, as Starlink is already positioning itself as the default high-speed option for carriers that value passenger satisfaction over incremental fees.

Musk’s focus on creating not only a great service but also a reasonable user experience highlights SpaceX’s prowess with Starlink as it continues to expand across new partners and regions.
