Tesla Semi, all-electric trucks get scathing criticism from auto tech expert

Published

on

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.

X experienced an outage on Monday morning, with tens of thousands of users reporting that the platform failed to load across both desktop and mobile. The disruption began around 8:02 a.m. ET, as per Downdetector data, and quickly escalated in the U.S. and U.K.

Monday’s outage follows a similar issue that befell the social media platform in mid-January.

Shortly after 8 a.m. ET, Downdetector showed a sharp rise in incident reports. At one point, U.S. complaints exceeded 40,000, while U.K. reports climbed past 6,000. Earlier in the outage, filings had already crossed 11,000 in the U.S. and 3,300 in the U.K., as noted in a TechRadar report. X users in other locations, such as the Philippines and Costa Rica, also reported similar issues.

Users attempting to access X were met with a “something went wrong” message. Feeds did not refresh, posts failed to appear, and both the social media platform’s app and web versions appeared affected by the issue. The outage struck during peak weekday usage, amplifying its visibility across regions worldwide.

X has not issued an official explanation for the latest outage or confirmed what caused the service disruption. The scale of complaints drew comparisons to the platform’s major outage in November 2025, which resulted in users being met with “Internal server error / Error code 500” messages, as well as Cloudflare-related error notices.

The incident also comes just weeks after X experienced a similar downtime in mid-January. That outage seemed more notable, however, with more than 100,000 users reporting issues with the social media platform on Downdetector.

Newly released bidding documents have shed light on how Elon Musk’s Boring Company plans to connect Universal Orlando Resort’s north campus to Universal Epic Universe. 

The materials outline staffing, construction timelines, tunnel configuration, and operational details that were not previously public about the planned Loop system.

The Shingle Creek Transit & Utility Community Development District voted Feb. 11 to begin contract negotiations with The Boring Company after ranking it the top bidder for the Universal Orlando transport project. Now, evaluation documents obtained by local news media reveal how the company intends to execute the project, according to Attraction Insight.

The proposal describes a twin-tunnel configuration, with one tunnel in each direction. It also noted that permitting, design, and construction could take roughly a year and a half once approvals are secured. The company indicated it could deploy multiple tunnel boring machines and install temporary support infrastructure, including muck storage pits and stormwater systems, during construction.

Bid documents list eight internal specialists assigned to the project, including tunnel engineers, structural engineers, and tunnel boring machine experts. Six subcontractors would handle fire protection, communications, soil treatment, and concrete work.

The company stated it “has the necessary internally produced tunneling equipment and personnel immediately available to complete this project for the district as quickly as permits and approvals can be obtained.”

Operationally, the system would mirror the company’s Las Vegas Loop model, using Tesla vehicles to provide point-to-point transport rather than fixed-route buses. The proposal frames the concept as “on-demand, express transportation,” with vehicles dispatched as needed and capacity adjustable in real time.

Stations could be built underground or above ground with ramp access into tunnels. The documents also referenced potential future integration of a configurable Robovan for passengers and cargo, though capacity projections for the Orlando tunnels have not yet been disclosed.

The proposal states that the Loop can integrate “easily into environmentally sensitive areas,” but it does not provide detailed mitigation plans for Central Florida’s high water table and limestone geology, which is susceptible to sinkholes. The company has stated that it intends to hire an Orlando-based geotechnical firm to evaluate soil conditions.

German authorities have opened an investigation into an IG Metall union representative following allegations that a confidential works council meeting at Tesla’s Gigafactory Berlin was secretly recorded. The probe follows a criminal complaint filed by Tesla management last week.

As per a report from rbb24, police seized a laptop belonging to an IG Metall member at Tesla Giga Berlin on Tuesday afternoon. Prosecutors in Frankfurt (Oder) confirmed that an investigation is underway into a possible unauthorized audio recording of an internal works council meeting.

Under German law, recording a non-public meeting without consent may constitute a criminal offense.

Tesla stated that Gigafactory Berlin employees alerted management after allegedly discovering that an external union representative, who was attending the event as a guest, had recorded the session. Plant manager André Thierig stated in a post on X that the representative was “caught in action,” prompting the company to contact police and file a criminal complaint.

The seized device is now part of the investigation, and authorities will determine whether any unlawful recording had indeed occurred.

IG Metall has denied the accusation. In comments to German media, representatives rejected Tesla’s claim and described the electric vehicle maker’s allegation as an election campaign tactic ahead of upcoming works council elections.

The election at Tesla’s Grünheide plant is scheduled for March 2–4, 2026, with about 11,000 employees being eligible to vote. Regular works council elections in Germany are held every four years between March and May.

The incident comes amid tensions between Tesla and organized labor in Germany. While works councils operate independently from unions, IG Metall has been active at the plant and has previously criticized Tesla’s labor practices. Authorities, for their part, have not yet announced whether charges will be filed, though the investigation remains ongoing.
