Tesla Semi payload estimates suggest critics underestimated battery tech advancements
The Tesla Semi truck’s payload will be comparable to a Class 8 diesel truck, according to the company’s 2020 Impact report. The Semi’s payload estimates address one persistent critique about Tesla’s Class 8 truck.
Early critics of the Semi believed the truck was impossible to produce given the weight capacity limitations of heavy-duty trucks. Although total weight load capacities may differ, on average, the limit for Class 8 trucks is 80,000 pounds. The 80,000-pound capacity includes the weight of the truck and its payload.
With all-electric heavy-duty trucks, manufacturers would have to account for the weight of battery packs. The heavier the battery, the less payload an electric Class 8 truck would be able to carry.
In 2017, many analysts and other experts concluded that the Semi would need a 600 kWh to 1,000 kWh battery pack to produce the truck’s 300 and 500-mile range variants. For perspective, Tesla’s 100 kWh battery packs typically weigh 1,300 pounds. So a 600 kWh pack would weigh almost 8,000 pounds.
However, Tesla has made notable advancements in battery technology since the Semi’s unveiling, including the introduction of the 4680 battery cells. According to Tesla’s estimates, 4680 cells are lighter but have a higher energy density, which could reduce the weight of the electric Semi.
Besides better battery technology, the trucking industry has also shifted since 2017. The United States and the European Union are now mulling over regulations in a world with electric vehicles, including all-electric trucks.
In its 2020 Impact Report, Tesla noted that the US and the EU approved higher weight allowances for heavy-duty electric trucks. In the EU, electric Class 8 trucks are allowed to be ~4,400 (2 tons) pounds heavier than diesel equivalents, while in the US, they were given an allowance of 2,000 pounds (0.9 tons).
The Tesla Semi’s production has been pushed back a few times since its 2017 unveiling. Elon Musk has stated that battery cell production is one of the bottlenecks causing delays in Semi production. A year after the pandemic, supply chain constraints, like the semiconductor shortage, contributed to the challenges in Semi production.
“The pace of the respective production ramps will be influenced by the successful introduction of many new product and manufacturing technologies, ongoing supply-chain related challenges and regional permitting. To better focus on these factories, and due to the limited availability of battery cells and global supply chain challenges, we have shifted the launch of the Semi truck program to 2022,” noted Tesla in its Q2 2021 Update Letter.

SpaceX is partnering with chipmakers to enable Starlink satellite-to-cell service
President Gwynne Shotwell outlined the effort during a space industry conference in Paris.

SpaceX is working with microchip manufacturers to integrate satellite-connectivity hardware into smartphones, advancing its plan for direct-to-device services through Starlink.
The move follows the company’s $17 billion acquisition of wireless spectrum from EchoStar Corp., a deal that positions SpaceX to operate more independently of traditional telecom carriers.
President Gwynne Shotwell outlined the effort during a space industry conference in Paris this week, as noted in a Bloomberg News report.
Starlink direct-to-device
Starlink currently serves millions of customers in over 100 countries, primarily through ground-based dishes. The company, however, is now expanding into satellite-to-cell service, which should enable unmodified phones to connect directly with orbiting satellites. While SpaceX has a partnership with T-Mobile US, the EchoStar spectrum purchase gives it more control to negotiate with global carriers on its own terms.
“We’re working with chip manufacturers to get the proper chips in phones,” the SpaceX President stated. “We will now be initiating discussions with telcos in a different way now. Now it’s our spectrum, but we want to work with them, almost providing capacity and wholesaling capacity to their customers.”
The company plans to launch satellites capable of supporting its direct-to-device business within two years, with early mobile phone testing expected by late 2026.
Starship program continues test flights
Shotwell also addressed SpaceX’s Starship program, which recently completed its 10th test flight in August. She said the mission met all objectives, providing a critical morale boost to teams after a challenging development year.
“My Starship team needed that win,” Shotwell noted. “Development programs always are kind of a 24/7 operation, and I was really pleased for them.”
SpaceX is planning to fly one more iteration of the current Starship prototype, known as V2, before transitioning to the next-generation V3 vehicle. That version, expected to debut late this year or early 2026, is designed to be more capable and support eventual crewed missions to the Moon and Mars.
“The V3, which we want to fly hopefully late this year, but maybe early next year, is really the vehicle that could take humans to the moon and Mars,” Shotwell stated.

Elon Musk says xAI has a chance to reach AGI with Grok 5
The comment came after Grok 4 posted strong results on the ARC-AGI benchmark.

Elon Musk suggested this week that his artificial intelligence startup xAI has the potential to reach artificial general intelligence (AGI) with the next version of its large language model, Grok 5.
The comment came after Grok 4 posted strong results on the ARC-AGI benchmark, which tests reasoning and problem-solving ability.
Musk sees Grok 5 as AGI candidate
In a post on X, user @amXFreeze shared the latest results of the ARC-AGI leaderboard, which showed Grok 4 outpacing rival systems such as OpenAI’s ChatGPT in problem-solving and open program synthesis tasks.
Musk reacted to the performance by stating that “I now think xAI has a chance of reaching AGI with Grok 5. Never thought that before.”
Artificial General Intelligence (AGI) refers to an AI system that is capable of matching or surpassing human-level intelligence across tasks such as thinking, reasoning, and other domains by a notable margin, as noted in a report from Benzinga. AI companies today are actively pursuing AGI.
xAI’s speed
While xAI was only established in March 2023, the startup has grown aggressively. Since its founding, it has rapidly risen in the AI segment and its Grok large language model has become a mainstream option for everyday users, especially on social media platform X. The company is still growing aggressively, and it is currently expanding its Colossus supercomputer cluster in Memphis.
During xAI’s Engineering Open House event in San Francisco in its early days, Elon Musk highlighted that speed would be the company’s primary competitive edge. To highlight this, Musk stated that “No SR-71 Blackbird was ever shot down and it only had one strategy: to accelerate.” So far, xAI is definitely playing this role very well.

Tesla lands new partnership with Uber as Semi takes center stage
Tesla and Uber will work together, using the company’s all-electric Semi, to make sustainable Class 8 electric trucks more affordable with three main strategies: Subsidized Pricing, Predictable Growth, and Optimization of Utilization.

The Tesla Semi has led to a new partnership between the company and Uber, as the two are launching a program that aims to revolutionize logistics by making sustainable commercial vehicles more accessible.
Uber announced on Tuesday that it was planning to launch the Dedicated EV Fleet Accelerator Program in a new partnership with Tesla. Uber’s Freight division is mainly responsible for the new program, which it calls a “first-of-its-kind buyer’s program designed to make electric freight more affordable and accessible by addressing key adoption barriers.”
Tesla and Uber will work together, using the company’s all-electric Semi, to make sustainable Class 8 electric trucks more affordable with three main strategies: Subsidized Pricing, Predictable Growth, and Optimization of Utilization.
- Subsidized Price: Fleets purchasing Tesla Semis through this program will receive a subsidy on the purchase price.
- Predictable Growth: Fleets will integrate their Tesla Semis into Uber Freight’s dedicated solutions for shippers for a pre-determined period. This creates an opportunity for carriers to forecast revenue with confidence, while shippers gain consistent access to reliable, zero-emission capacity.
- Optimize Utilization: Uber Freight taps into its extensive freight network to match carriers with consistent, high-quality freight from our strong shipper base—helping ensure the addition of these Tesla Semis stay fully utilized and carriers see dedicated, real, measurable returns from the start
Tesla will work directly with interested companies to iron out technical details about the Semi, as well as its cost of ownership based on the tailored needs of their business. Fleets can expect savings on the first day, Uber says, as they will avoid diesel fuel costs and reduced maintenance, a widely known advantage of EVs.
Uber announced that it had partnered with select carriers to pilot the Dedicated EV Fleet Accelerator Program prior to its launch:
“During the 2-month pilot program, the Tesla Semis showcased both reliability and efficiency for Uber Freight’s shipper network. Over 394 hours of drive time, carriers covered 12,377 miles. With an average net energy consumption of just 1.72 kWh per mile and only 60 hours of total charge time, these results highlight the operational viability of Tesla Semis on demanding freight lanes. “
In its press release launching the program, Uber effectively highlights how the use of the Semi can impact a company’s margins and profitability through fuel savings, reduced maintenance costs, and lower total cost of ownership.
This is something that turns so many people away from gas cars and toward EVs, so it’s no surprise that Uber wanted to emphasize this point on a larger scale with a company that utilizes a fleet of vehicles.
Tesla Semi shows strong results in ArcBest’s real-world freight trial
Tesla has been experimenting with a select group of companies, as well. It partnered with PepsiCo. several years ago, in an effort to launch a pilot program for the Semi. It had excellent results, showing higher efficiency, lower costs, and an exceptional ability to handle long runs.
Drivers have had a lot of positive things to say:
The Semi will enter mass production next year, but we anticipate that some companies will commit to Uber’s new platform well before then.
