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.

The Boring Company said its Vegas Loop system transported roughly 82,000 passengers during the recent CONEXPO-CON/AGG construction trade show in Las Vegas. The event was held at the Las Vegas Convention Center (LVCC) from March 3-7, 2026. 

The Loop’s feat was highlighted by The Boring Company in a post on its official account on social media platform X.

CONEXPO-CON/AGG 2026

CONEXPO-CON/AGG is one of the largest construction trade shows in North America. This year’s event was quite impressive, attracting more than 140,000 construction professionals from 128 countries across the world.

Considering the number of this year’s attendees, the LVCC Loop seemed to have proven itself to be a very useful transportation solution. A video posted by The Boring Company on its official X account featured attendees expressing their enthusiasm for the underground transport system, with some stating that they would like to see similar tunnels across Las Vegas.

The LVCC Loop is only part of the greater Vegas Loop network, which is actively under construction.

New Vegas Loop extensions

One of the newest additions is a station at the Fontainebleau Las Vegas resort on the Strip. The station is located on level V-1 of the resort’s south valet area, according to a report from the Las Vegas Review-Journal. From the Fontainebleau, passengers can travel free of charge to stations serving the Las Vegas Convention Center, as well as to Loop stations at Encore and Westgate.

The system is also expanding beyond the Strip corridor. In December, The Boring Company began offering Vegas Loop rides to and from Harry Reid International Airport. These trips include a limited above-ground segment after receiving approval from the Nevada Transportation Authority to allow surface street travel tied to Loop operations.

The Boring Company President Steve Davis previously told the Review-Journal that the University Center Loop segment, which is currently under construction, is expected to open in the first quarter of 2026. The extension would allow Loop vehicles to travel beneath Paradise Road between the convention center and the airport, with a planned station just north of Tropicana Avenue.

Tesla preps to build its most massive Supercharger yet: 400+ V4 stalls

The project will be an expansion of the current Eddie World Supercharger in Yermo, California, and will take place in several stages.

Tesla is preparing to build its most massive Supercharger yet, as it recently submitted plans for an over 400-stall Supercharging station in California, which would dwarf its massive 168-stall location in Lost Hills, California.

The project will be an expansion of the current Eddie World Supercharger in Yermo, California, and will take place in several stages.

The expansion, adjacent to the existing Eddie World Supercharger, which is currently comprised of 22 older V2 and V3 stalls limited to 150 kW, unfolds across six phases.

Construction on Phase 1 begins later this year with 72 V4 stalls. Subsequent stages will progressively add hundreds more, culminating in over 400 next-generation chargers. Site plans label expansive parking arrays across Phases 1–5 along Calico Boulevard, with Phase 6 design still to be determined.

The project was first flagged by MarcoRP, a notable Tesla Supercharger watcher.

Strategically located midway on I-15 between Los Angeles and Las Vegas, the station targets heavy EV traffic on this high-demand corridor.

The surrounding 20-mile stretch already hosts over 200 high-power stalls (including 40 at 250 kW, 120 at 325 kW, and more), plus 96 in nearby Baker—yet bottlenecks persist during peak travel.

In scale, it eclipses all existing Tesla Superchargers. The current record holder, the solar- and Megapack-powered “Project Oasis” in Lost Hills, California, offers 164 stalls. Barstow’s former leader had 120. Eddie World 2 will be more than double that size, cementing Tesla’s dominance in ultra-high-capacity charging.

Tesla finishes its biggest Supercharger ever with 168 stalls

Development blends charging with convenience. Architectural drawings show integrated retail: a 10,100 square foot Cracker Barrel, a 4,300 square foot McDonald’s, a 3,800 square foot convenience store, additional restaurants, drive-thrus, outdoor dining, and lease space.

EV-centric features include pull-through bays for Cybertrucks and trailers, ensuring accessibility for larger vehicles and future Semi trucks.

This phased approach minimizes disruption while scaling capacity. It supports Tesla’s broader vision amid rising EV adoption, Robotaxi corridors, and long-haul needs. Once complete, Eddie World 2 won’t just charge vehicles; it will redefine highway stops, turning a dusty desert exit into a futuristic EV oasis.

Tesla makes latest move to remove Model S and Model X from its lineup

Tesla’s latest decisive step toward phasing out its flagship sedan and SUV was quietly removing the Model S and Model X from its U.S. referral program earlier this week.

Tesla has made its latest move that indicates the Model S and Model X are being removed from the company’s lineup, an action that was confirmed by the company earlier this quarter, that the two flagship vehicles would no longer be produced.

Tesla has ultimately started phasing out the Model S and Model X in several ways, as it recently indicated it had sold out of a paint color for the two vehicles.

Now, the company is making even more moves that show its plans for the two vehicles are being eliminated slowly but surely.

Tesla’s latest decisive step toward phasing out its flagship sedan and SUV was quietly removing the Model S and Model X from its U.S. referral program earlier this week.

The change eliminates the $1,000 referral discount previously available to new buyers of these vehicles. Existing Tesla owners purchasing a new Model S or Model X will now only receive a halved loyalty discount of $500, down from $1,000.

The updates extend beyond the two flagship vehicles. New Cybertruck buyers using a referral code on Premium AWD or Cyberbeast configurations will no longer get $1,000 off. Instead, both referrer and buyer receive three months of Full Self-Driving (Supervised).

The loyalty discount for Cybertruck purchases, excluding the new Dual Motor AWD trim level, has also been cut to $500.

These adjustments apply only in the United States, and reflect Tesla’s broader strategy to optimize margins while boosting adoption of its autonomous driving software.

The timing is no coincidence. Tesla confirmed earlier this year that Model S and Model X production will end in the second quarter of 2026, roughly June, as the company reallocates factory capacity toward its Optimus humanoid robot and next-generation vehicles.

With annual sales of the low-volume flagships already declining (just 53,900 units in 2025), incentives are no longer needed to drive demand. Production is winding down, and Tesla expects strong remaining interest without subsidies.

Industry observers see this as the clearest sign yet of an “end-of-life” phase for the vehicles that once defined Tesla’s luxury segment. Community reactions on X range from nostalgia, “Rest in power S and X”, to frustration among long-time owners who feel perks are eroding just as the models approach discontinuation.

Some buyers are rushing orders to lock in final discounts before they vanish entirely.

For Tesla, the move prioritizes efficiency: fewer discounts on outgoing models, a stronger push for FSD subscriptions, and a focus on high-margin Cybertruck trims amid surging orders.

Loyalists still have a narrow window to purchase a refreshed Plaid or Long Range model with remaining incentives, but the message is clear: Tesla’s lineup is evolving, and the era of the original flagships is drawing to a close.
