Tesla Semi performance data suggests the hype is real

Published

on

Data from GEOTAB and the North American Council for Freight Efficiency (NACFE) shows the true capability of the Tesla Semi. From the information gathered, the Tesla Semi seems to be living up to the hype.

Data from the Run for Less event hints at the capabilities of the Tesla Semi. Tesla’s Class-8 truck was put through the ringer at the event, operating on its maximum payload capacity and traveling up to 500 miles round trip.

Dave Mullaney from Rocky Mountain Institute shared some information from Tesla Semi runs. During Run for Less, GEOTAB and the NACFE collected data from three PepsiCo Tesla Semi trucks. Mullaney shared the results of each Tesla Semi’s performance from the first day.

Tesla Semi 1:

  • 335 miles on a single charge over 8 hours. [The] day ended with 17.5% SOC left, good for a little bit of a buffer.
  • [The] Truck was doing highway operations – driving 65% of the time with speed predominantly at 62 mph.

Tesla Semi 2:

  • 227 miles over about 6 hours. [The] day ended with 27% SOC.
  • Spent about half its time idle but mostly [at] highway speeds when driving

Note: This truck may have been loaded more heavily as it showed a somewhat shorter range than Truck 1.

Tesla Semi 3:

  • 377 miles with SOC bottoming out at 1.6% – no buffer there!
  • [A]lmost exclusively highway driving at 62 mph.

Based on the data he analyzed, Mullaney concluded that Tesla’s range estimates for the Semi were on point. He noted that there was still a lot about the Tesla Semi’s capabilities that is unknown. More tests would provide a better idea of the Tesla Semi’s capabilities.

“Takeaway is that the 350-mile truck is for real, but unknowns remain. Load weight wasn’t published, and weather was warm with low winds. If you want to push these things much beyond 350 in real-world operations, you will need opportunity charging to feel safe doing so. In future days, hopefully, the data will show interesting charging events so we can infer how much time that will take,” Mullaney stated in a LinkedIn post.

Tesla has applied to conduct local Full Self-Driving (Supervised) testing in the city of Jönköping, Sweden.

As per local outlet Jönköpings-Posten, Tesla has contacted the municipality with a request to begin FSD (Supervised) tests in the city. The company has already received approval to test its Full Self-Driving (Supervised) software in several Swedish municipalities, as well as on the national road network.

Sofia Bennerstål, Tesla’s Head of Public Policy for Northern Europe, confirmed that an application has been submitted for FSD’s potential tests in Jönköping.

“I can confirm that we have submitted an application, but I cannot say much more about it,” Bennerstål told the news outlet. She also stated that Tesla is “satisfied with the tests” in the region so far.

The planned tests in Jönköping would involve a limited number of Tesla-owned vehicles. Trained Tesla safety drivers would remain behind the wheel and be prepared to intervene if necessary.

Tesla previously began testing in Nacka municipality after receiving local approval. At the time, the company stated that cooperation between authorities, municipalities, and industry enables technological progress and helps integrate future transport systems into real-world traffic conditions, as noted in an Allt Om Elbil report.

If approved, Jönköping would become the latest Swedish municipality to allow local Full Self-Driving (Supervised) testing.

Tesla’s Swedish testing program is part of the company’s efforts to validate its supervised autonomous driving software in everyday traffic environments. Municipal approvals allow Tesla to gather data in urban settings that include roundabouts, complex intersections, and mixed traffic conditions.

Sweden has become an increasingly active testing ground for Tesla’s driver-assistance software in Europe, with regulatory coordination between local authorities and national agencies enabling structured pilot programs.

Microsoft has announced a new collaboration with Starlink as part of its expanding digital access strategy, following the company’s claim that it has extended internet connectivity coverage to more than 299 million people worldwide.

The update was shared ahead of Mobile World Congress, where Microsoft detailed how it surpassed its original goal of bringing internet access to 250 million people by the end of 2025.

In a blog post, Microsoft confirmed that it is now working with Starlink to expand connectivity in rural and hard-to-reach regions.

“Through our collaboration with Starlink, Microsoft is combining low-Earth orbit satellite connectivity with community-based deployment models and local ecosystem partnerships,” the company wrote.

The partnership is designed to complement Microsoft’s existing work with local internet providers and infrastructure companies across Africa, Latin America, and India, among other areas. Microsoft noted that traditional infrastructure alone cannot meet demand in some regions, making low-Earth orbit satellite connectivity an important addition.

Kenya was cited as an early example. Working with Starlink and local provider Mawingu Networks, Microsoft is supporting connectivity for 450 community hubs in rural and underserved areas. These hubs include farmer cooperatives, aggregation centers, and digital access facilities intended to support agricultural productivity and AI-enabled services.

Microsoft stated that 2.2 billion people globally remain offline, and that connectivity gaps risk widening as AI adoption accelerates.

Starlink’s expanding constellation, now numbering more than 9,700 satellites in orbit, provides near-global coverage, making it one of the few systems capable of delivering broadband to remote regions without relying on terrestrial infrastructure.

Starlink is expected to grow even more in the coming years as well, especially as SpaceX transitions its fleet to Starship, which is capable of carrying significantly larger payloads compared to its current workhorse, the Falcon 9.

Tesla expands US LFP battery supply with LG Energy Solution deal: report

The report was initially published by TheElec, citing industry sources.

LG Energy Solution (LGES) will manufacture lithium iron phosphate (LFP) energy storage system (ESS) batteries for Tesla at its Lansing, Michigan facility. 

The report was initially published by TheElec, citing industry sources.

LG Energy Solution’s Lansing plant, formerly known as Ultium Cells 3, was previously operated as a joint venture with General Motors. LGES acquired GM’s stake in May 2025 and now fully owns the site. With a production capacity of 50 GWh per year, it is one of the company’s largest facilities in North America.

LG Energy Solution is converting part of the Lansing factory to produce LFP batteries for energy storage systems. Equipment orders for the new lines have already been placed, and mass production is reportedly expected to begin in the second half of next year.

Last July, LG Energy Solution disclosed a 5.94 trillion won battery supply agreement running from August 2027 to July 2030. While the company did not name the customer, industry sources pointed to Tesla as the buyer.

Tesla has primarily used CATL’s prismatic batteries for its Megapack systems. The move to source prismatic LFP cells from LG Energy Solution’s U.S. plant could then be seen as part of Tesla’s efforts to bolster its North American supply base for its energy storage business.

For the Lansing conversion, LG Energy Solution reportedly plans to use electrode equipment originally ordered under its Ultium Cells venture with General Motors. Suppliers reportedly include CIS and Hirano Tecseed for electrode systems, TSI for mixing equipment, CK Solution for heat exhaust systems, A-Pro for formation equipment, and Shinjin Mtech for assembly kits.

Tesla currently manufactures energy storage products at facilities in California and Shanghai, though another Megafactory that produces the Megapack is also expected to be built in Texas. As per recent reports, the Texas Megafactory recently advanced with a major property sale.
