The Tesla Semi will shake the trucking industry to its roots
Elon Musk’s new Master Plan calls for an expansion of its vehicles into other categories, including buses and heavy duty trucks, both of which will unveiled in about a year. Undoubtedly, carbon emissions worldwide would fall precipitously if the general automobile consumer transitioned to a tailpipe-free electric Tesla, but that’s not what Elon Musk is after. His goal is a full frontal assault on carbon emissions of all kinds including a Tesla Semi. His objective is for nothing less than a world that no longer uses fossil fuels to power its transportation system, even on a commercial scale.
Looking back at the Volkswagen diesel scandal and why it was significant, beyond morality, diesel engines especially heavy-duty diesel trucks spew emissions on another level. To make the problem worse, passenger cars normally have a useful life of around 200,000 miles. Diesel powered tractors can be on the road for a decade or more, spewing out toxins for millions of miles before they are replaced. The pollution control systems on older trucks are rudimentary at best.
In Southern California, the pollution from drayage trucks that haul shipping containers from ports to inland distribution centers is so bad, it has sparked a number of plans to replace them with electric versions. One solution proposed by Siemens calls for equipping trucks with pantographs so they can draw electricity from overhead wires along their routes.
Former Tesla executive Ian Wright sold his stock in Tesla Motors when Elon Musk came on board. Wright wanted to attack the challenges of truck pollution rather than build some silly sports car. He has since created his own company called Wrightspeed that focuses on cleaning up the emissions from heavy duty garbage trucks. He has invented a new form of hybrid powertrain that uses a small gas turbine to recharge the batteries. The turbine is so clean, it doesn’t even need a catalytic converter to meet California’s stringent emissions rules.
The problem with electric trucks today is that the batteries need to be so large and heavy they would take up much of the space available for hauling freight. Not only that, they would be prohibitively expensive. The Wrightspeed system is a compromise that attempts to strike a balance between cost and range. It has attracted international attention and the company has recently signed a contract to re-power a fleet of diesel buses in New Zealand.
The allure of electric trucks has created an opportunity for hucksters and charlatans. Earlier this year, a Florida company calling itself Oakridge Global Energy Solutions said it had developed a battery for Freedom Trucking of Minneapolis that would haul an 80,000 lb. load 400 miles. That claim turned out to be vaporware.
Another entrant into the heavy truck sweepstakes is a company calling itself Nikola Motors — a rather obvious attempt to somehow conflate what it is doing with the work of Tesla Motors. It says its Nikola One tractor will have 2,000 horsepower. 3,700 lb-ft of torque, a 325 kWh battery, 6 wheel drive with torque vectoring and 1,200 miles of range. It relies on an onboard natural gas turbine to keep the battery charged while driving.
The design concept for the Nikola One is visually appealing and the company says it has 7,000 pre-orders for the truck worth a total of $2.3 billion. Of course, it currently has no factory, no battery factory, and little corporate infrastructure other than its website.
We can assume the Tesla Semi will not have a range extender engine of any type. How Tesla will make an electric tractor that can haul heavy loads long distances that is cost competitive remains unclear. But if Elon says that’s what Tesla will do, we can be pretty sure it will — eventually.
JB Straubel says he and Elon talked about electric airplanes long before they decided to build automobiles. And ocean going cargo vessels are some of the worst polluters on the face of the planet. Musk probably has a plan for them, too. Look for those ideas to be part of Master Plan Numero Tres.
Tesla is set to inaugurate its dedicated Semi factory in Sparks, Nevada, this evening, but drone footage has already started to show who is expected on the handover stage.
Zanegler, a drone operator who regularly documents Tesla Semi operations in Nevada, filmed a row of new-generation Semi units parked outside of the plant with customer branding applied. The liveries visible in the video include companies like PepsiCo, U.S. Foods, Einride, DHL, WattEV, and others that have committed to utilizing Tesla’s Class 8 electric truck in their fleets.

Several of those company names already sit within Tesla’s public ordering book, including PepsiCo, which has been the program’s primary anchor customer since the first Semi deliveries in December 2022. PepsiCo now runs dozens of Tesla Semi units in daily service, with drivers completing regional routes.
Einride placed a 500-unit order in August, which was, at the time, the largest single Semi commitment. First deployments of their Semi units are planned for this month and will eventually span across California, Texas, New Jersey, Illinois, and Georgia. Meanwhile, IMC Logistics announced a 50-truck California order this week.
Tesla Semi lands the biggest electric truck deal in U.S. history
Other names, like LTS, OK Produce, and HMD, have not been widely confirmed as firm buyers, but their presence on the lot is perhaps the clearest signal that Tesla intends to expand on that list this evening at the event.
Tesla first unveiled the Semi back in 2017 with a 2019 production target.
Limited pilot builds reached PepsiCo in late 2022, and high-volume production began at the new 1.7-million-square-foot plant that sits logically positioned next to Tesla’s Gigafactory Nevada. Tesla Semi program director Dan Priestley has said that Tesla expects to build “many thousands” of Semi units this year, but as with every Tesla release, there have been set expectations of an S-curve ramp.
Outside estimates still put 2026 deliveries in the 5,000-to-15,000 range, but it will ultimately depend on Tesla’s readiness to put those units out, as well as how smoothly production is moving internally.
Tesla’s Semi Rollout event is set to start tonight at the Sparks factory, and it will be livestreamed on X starting at 6 p.m. PDT / 9 p.m. ET.
The Tesla App is now giving owners a better indication of what to expect when visiting a Supercharger site, as it is now sharing Site Maps in the app itself, making the feature no longer exclusively available in the car.
Tesla owners can now preview a Supercharger’s layout and live stall status from their phone thanks to the App’s new software version, v4.61.0. Zooming into a supported Supercharger on the charging map now switches the familiar street view into a site-specific map that shows stall positions, occupied bays, out-of-service posts, and a live count of open Superchargers.
It will even show you which specific Tesla model is charging at each occupied stall.

This is the same view drivers first saw inside the car with the 2025 Holiday Update, which started as a pilot for Tesla in California and Texas. Those early maps showed layout, nearby amenities, and the status of each operational stall. The feature has spread to most Superchargers in the U.S., but now Tesla wants the feature available through the Smartphone App, which is now rolling out to owners.
The in-vehicle screen maps remain a richer 3D canvas and originally required AMD Ryzen infotainment hardware, which left many Intel-based Model 3 and Model Y owners without the view. The app version removes that hardware barrier, so any owner can now get a preview of their upcoming Supercharger stop on their phone.
Anyone with the updated version of the app can open a Site Map on their phone. The feature has provided some additional peace of mind to anxious travelers and those who might be looking for a place that is less congested for faster charging speeds. It is a meaningful addition to many owners, especially for trips to unfamiliar locations.
You can now pick a Supercharger location that might be more aligned with what you are looking for or need: you can pick a site based on what stalls are open, where ADA stalls sit, how you will pull in, and more, instead of circling a crowded lot after arriving. Owners of older cars now have access to the feature without having to purchase a new vehicle altogether.
Site Mpas will not reserve a stall, nor will it change how Fast Charging works. Tesla does something simpler and more useful by giving owners a dedicated preview of the Supercharger they’re about to charge, turning an unknown parking lot into a place that may seem more familiar thanks to the preview.

Tesla Optimus Gen 3 shows off a cleaner, factory-ready design in new app discovery
Renders hidden inside Tesla’s Android app show Optimus Gen 3’s design before any official reveal.

Tesla may have accidentally given a first look at its newest Optimus Gen 3 humanoid robot when photos were found in the Tesla smartphone app.
Design files tucked inside a recent Android version of the Tesla app appear to show the third generation humanoid robot next to the older Gen 2.5 prototype. The assets were extracted from the app package by Tesla community member @wholemars, who posted the renders on X late Tuesday night before deleting them. The Tesla Newswire reshared the side by side comparison on Wednesday, and the images have circulated widely since.
Tesla Optimus Gen 2.5 vs Gen 3 comparison via @WholeMars on X
The files are labeled “gen3” and were built as models for Tesla app’s own interface, as validated directly by Grok to be official.
The comparison shows a robot that looks built for a factory line rather than a lab bench. Gen 2.5’s exposed mechanical linkages and gold plating on the knees and shins are gone. In their place, Gen 3 uses matte black fairings on the lower legs, paired with a more contoured champagne gold body. Flexible covers now seal the joint where the torso meets the upper thighs, keeping bearings and moving parts sealed from debris and unnecessary contact.
The body panels fit more tightly, and the hands, which Tesla has said carry 22 degrees of freedom, look far more refined than those on earlier units.
This most recent leak fills a gap Tesla has left open for most of the year. Elon Musk said on March 31 that Optimus 3 was walking around but needed “some finishing touches” before it could be shown, a delay Teslarati covered when Tesla missed its first quarter reveal target. Musk later said Tesla would hold the design back until closer to production, partly to keep competitors from copying it. No reveal date has been announced.
The app itself has been preparing for Optimus for months. In July, code in the Tesla app pointed to a dedicated robot phone key, a consent screen for collecting video and spatial data while Optimus works inside a home, and an alert system for low battery and mechanical faults. Finished 3D models of Gen 3 suggest the interface owners will eventually use is moving past placeholder code toward something Tesla intends to ship.
Manufacturing is moving in parallel. Tesla tore out the original Model S and Model X lines at Fremont this summer to make room for Optimus production, with a planned capacity of one million robots a year. At Giga Texas, the steel frame of a dedicated Optimus factory is nearing completion ahead of a targeted 2027 start, with Musk pointing to an eventual output of 10 million units annually.
