Tesla Semi, all-electric trucks get scathing criticism from auto tech expert
The Tesla Semi might be receiving a lot of interest from companies and the electric vehicle community as a whole, but an automotive technology expert from Germany is not that impressed. In a statement, Chair of Automotive Engineering at the Technical University of Munich Markus Lienkamp criticized all-electric trucks like the Tesla Semi, stating that such vehicles are pretty much pointless in the economic and ecological sense.
“The battery for a Tesla Semi must have a capacity of about 1000 kWh, per 100 kilometers about 130 kilowatt-hours. This is technically not easily feasible and it’s also pointless both economically and ecologically,” he said.
Lienkamp’s scathing criticism comes on the heels of a study from Transport and Environment, a consortium of European environmental organizations that conducted a study comparing the energy consumption and environmental costs of conventional diesel trucks and their all-electric counterparts. Two diesel trucks were used for the study: one with an average consumption of 33 liters per 100 kilometers (around 7 mpg) and a more aerodynamic truck with a consumption of 22 liters per 100 km (10.69 mpg).
The results of Transport and Environment’s study found that diesel trucks consume between 2.2-3.3 kilowatt-hours per kilometer, far above the consumption of an average electric truck, which requires 1.44 kWh per km. Electric vehicles that are designed from the ground up for maximum efficiency such as the Tesla Semi require just 1.15 kWh per km. The study’s authors concluded that overall, using all-electric trucks reduces energy consumption by a factor of 1.5-2.9.
All-electric trucks surpass diesel trucks in terms of efficiency as well. The study revealed that a diesel truck engine has an efficiency of 20-45% on long-haul routes and a measly 10% in city traffic. In comparison, electric trucks have a 90% efficiency for long routes and 75% in urban traffic. Lienkamp is not convinced, arguing that the source of the electricity used by vehicles like the Tesla Semi affects efficiency.
“The efficiency of the electricity mix used for the truck battery is important. If the energy comes from a gas-fired power plant, for example, the overall efficiency quickly drops back to 40%. If, on the other hand, 80% to 90% of the electricity comes from renewable sources, as planned in the EU for 2040, long-distance trucks would be attractive from an ecological point of view,” he said.
The authors of the study maintained that electric trucks are cheaper to repair and maintain simply because they have fewer moving parts. Even brakes will rarely need replacing, thanks to systems like regenerative braking. While these are compelling advantages, Lienkamp stated that “for distances of 500 kilometers and beyond, battery-powered trucks simply won’t make any economic sense until 2030,” adding “with electric vehicles, the cost of trying to reduce CO2 levels is simply too high.”
It should be noted that the Tesla Semi, at least in its upcoming iteration, is not designed to enter the long-haul market that is dominated by trucks that can go over 1,000 miles in one full tank. Rather, the Tesla Semi is designed to compete in short-range routes that range from 300-500 miles. From this perspective, it becomes difficult to argue against the Tesla Semi.
The Tesla Semi is a Class 8 truck, and with its four Model 3-derived electric motors, the all-electric long-hauler is capable of sprinting from 0-60 mph in just 5 seconds without a trailer. With a full load, the Semi can reach highway speeds in 20 seconds, far quicker than conventional diesel trucks. The Tesla Semi is currently undergoing real-world tests, in preparation for its production, which is expected to start either this year or sometime in 2020.

SpaceX to launch Starlink V2 satellites on Starship starting 2027
The update was shared by SpaceX President Gwynne Shotwell and Starlink Vice President Mike Nicolls.
SpaceX is looking to start launching its next-generation Starlink V2 satellites in mid-2027 using Starship.
The update was shared by SpaceX President Gwynne Shotwell and Starlink Vice President Mike Nicolls during remarks at Mobile World Congress (MWC) in Barcelona, Spain.
“With Starship, we’ll be able to deploy the constellation very quickly,” Nicolls stated. “Our goal is to deploy a constellation capable of providing global and contiguous coverage within six months, and that’s roughly 1,200 satellites.”
Nicolls added that once Starship is operational, it will be capable of launching approximately 50 of the larger, more powerful Starlink satellites at a time, as noted in a Bloomberg News report.
The initial deployment of roughly 1,200 next-generation satellites is intended to establish global and contiguous coverage. After that phase, SpaceX plans to continue expanding the system to reach “truly global coverage, including the polar regions,” Nicolls said.
Currently, all Starlink satellites are launched on SpaceX’s Falcon 9 rocket. The next-generation fleet will rely on Starship, which remains in development following a series of test flights in 2025. SpaceX is targeting its next Starship test flight, featuring an upgraded version of the rocket, as soon as this month.
Starlink is currently the largest satellite network in orbit, with nearly 10,000 satellites deployed. Bloomberg Intelligence estimates the business could generate approximately $9 billion in revenue for SpaceX in 2026.
Nicolls also confirmed that SpaceX is rebranding its direct-to-cell service as Starlink Mobile.
The service currently operates with 650 satellites capable of connecting directly to smartphones and has approximately 10 million monthly active users. SpaceX expects that figure to exceed 25 million monthly active users by the end of 2026.

Elon Musk’s xAI and X to pay off $17.5B debt in full: report
The update was shared initially in a report from Bloomberg News, which cited people reportedly familiar with the matter.
Elon Musk’s social platform X and artificial intelligence startup xAI are reportedly preparing to repay approximately $17.5 billion in outstanding debt in full.
The update was shared initially in a report from Bloomberg News, which cited people reportedly familiar with the matter.
Morgan Stanley, which arranged the debt financing for both companies, has reportedly informed existing lenders that X and xAI plan to pay back the full amount of the $17.5 billion debt. Bloomberg’s sources did not disclose where the capital for the repayment would be coming from.
X, formerly known as Twitter, assumed roughly $12.5 billion in debt during Musk’s acquisition of the company. xAI separately borrowed about $5 billion through bonds and loans last June. The two firms merged last year under xAI Holdings.
Bloomberg noted that portions of the debt are relatively recent and may carry early repayment penalties. xAI’s $3 billion in high-yield bonds are expected to be redeemed at 117 cents on the dollar, reflecting a premium since the debt was expected to stay outstanding for at least two years.
X has been servicing tens of millions of dollars in monthly debt payments, while xAI has reportedly been burning approximately $1 billion in cash per month as it invests heavily in data centers, chips, and AI talent. That being said, xAI also concluded a funding round in January, where it raised $20 billion of new equity.
The repayment plans come as Musk consolidates several of his businesses. SpaceX recently acquired xAI, making it a subsidiary as the company explores plans for space-based data centers. The combined entity has been valued at approximately $1.25 trillion.
Bloomberg previously reported that SpaceX is targeting a confidential IPO filing as soon as this month, potentially positioning the private space firm for a public listing later this year. Representatives for Morgan Stanley declined to comment, and X and xAI did not immediately respond to requests for comment.

Tesla Giga Berlin head calls out Handelsblatt’s claimed 2025 production figures
Andre Thierig, Senior Director of Manufacturing at Giga Berlin, published a detailed post on LinkedIn challenging several points made in the publication’s coverage of the Grünheide facility.
Tesla Gigafactory Berlin’s plant manager has publicly pushed back against recent reporting by German business publication Handelsblatt, which cited reportedly erroneous data about the factory’s production figures and financial performance.
Andre Thierig, Senior Director of Manufacturing at Giga Berlin, published a detailed post on LinkedIn challenging several points made in the publication’s coverage of the Grünheide facility.
In his LinkedIn post, Thierig called out Handelsblatt’s claim that 149,000 Model Y vehicles were produced at Giga Berlin in 2025. He noted that “the article is simply filled from front to back with false information and claims!
“I have to set the record straight here! In the last article about Tesla in Grünheide, the Handelsblatt speaks e.g. of 149,000 Model Ys built in 2025. WRONG!
“In 2025, we again produced over 200,000 vehicles. And this despite the fact that we stopped production in Q1 for the changeover to the new Model Y and then ramped it up again to 5,000 units per week over several weeks,” Thierig wrote.
He added that production increased each quarter in 2025 compared to the prior quarter and stated that more than 700,000 Model Y units have been produced at Grünheide since manufacturing began in 2022. For the first quarter of 2026, he stated that the factory is planning another production increase compared to the fourth quarter of 2025.
Thierig also questioned Handelsblatt’s reported 0.74% profit margin, writing that how the publication calculated the figure “remains reserved for their secret ‘calculation skills.’”
Beyond production data, Thierig highlighted Tesla’s broader footprint in Germany, stating that the company has invested more than €5 billion in Grünheide since 2020 and created nearly 11,000 permanent, above-tariff jobs. He added that Tesla is currently investing nearly €100 million into battery cell production at the site, which is expected to generate several hundred additional positions.
In a follow-up comment, Thierig noted that he did communicate with the publication’s editor-in-chief in an effort to “start fresh,” but he was informed that Handelsblatt’s current approach works just fine.
“Last year, I spoke to a representative of the Handelsblatt editor-in-chief and suggested that we “start anew” again. Handelsblatt turned down this offer on the grounds that their current approach works well for them,” Thierig noted.
Sönke Iwersen, Head of Investigative Research at Handelsblatt, responded to Thierig’s post, stating that the newspaper’s figures were based on Tesla’s own annual financial statements for the Grünheide entity.
He cited reported 2024 revenue of €7.68 billion, operating profit of €156.8 million, and net income after taxes of €55.6 million. Iwersen also referenced prior public comments from Elon Musk about Cybertruck demand, noting the gap between reported pre-orders and subsequent annual sales figures.
He also stated that the works council election eligibility figures Giga Berlin had dropped to 10,703 employees today from 12,415 two years ago.
“As far as production figures are concerned, these are figures from the data service provider Inovev. This is also stated in the article. Please compare this with Elon Musk’s information on demand for the Cybertruck. According to Musk, there were one million pre-orders. In the first year, 39,000 units were sold, in the second year 20,000. How can this be explained? With a million pre-orders?
“You yourself have repeatedly pointed out in recent months that no jobs would be cut in Grünheide because Tesla is different from the competition. Now a new works council is being elected in Grünheide. 10,703 people are eligible to vote. Two years ago, 12,415 people were eligible to vote. So there were exactly 1712 fewer from 2024 to 2026,” Iwersen wrote.
