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.

Elon Musk launches TERAFAB: The $25B Tesla-SpaceXAI chip factory that will rewire the AI industry
Tesla, SpaceX, and xAI unveiled TERAFAB, a $25B chip factory targeting one terawatt of AI compute annually.
Elon Musk took the stage over the weekend at the defunct Seaholm Power Plant in Austin, Texas, to officially unveil TERAFAB, a $20-25 billion joint venture between Tesla, SpaceX, and xAI that he described as “the most epic chip building exercise in history by far.” The announcement marks the most ambitious infrastructure bet Musk has made since Gigafactory 1 in Sparks, Nevada, and it fuses three of his companies into a single, vertically integrated AI hardware machine for the first time.
TERAFAB is designed to consolidate every stage of semiconductor production under one roof, including chip design, lithography, fabrication, memory production, advanced packaging, and testing. At full capacity, the facility would scale to roughly 70% of the global output from the current world’s largest semiconductor foundry from Taiwan Semiconductor Manufacturing Company (TSMC).
Elon Musk’s stated goal is one terawatt of computing power annually, split between Tesla’s AI5 inference chips for vehicles and Optimus robots, and D3 chips built specifically for SpaceXAI’s orbital satellite constellation.
Tesla Terafab set for launch: Inside the $20B AI chip factory that will reshape the auto industry
The logic behind the merger of these three entities is rooted in a supply chain crisis Musk has been signaling for over a year. At Tesla’s Q4 2025 earnings call, he warned investors that external chip capacity from TSMC, Samsung, and Micron would hit a ceiling within three to four years. “We’re very grateful to our existing supply chain, to Samsung, TSMC, Micron and others,” Musk acknowledged at the Terafab event, “but there’s a maximum rate at which they’re comfortable expanding.” Building in-house was, in his framing, not a strategic option, but a necessity.
The space angle is where the announcement becomes genuinely unprecedented. Musk said 80% of Terafab’s compute output would be directed toward space-based orbital AI satellites, arguing that solar irradiance in space is roughly 5x greater than at Earth’s surface, and that heat rejection in vacuum makes thermal scaling viable. This directly feeds the SpaceXAI vision, which is betting that within two to three years, running AI workloads in orbit will be cheaper than doing so on the ground. The satellites, powered by constant solar energy, would effectively turn low Earth orbit into the world’s largest data center.
Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI
Historically, this announcement threads together every major Musk initiative of the past two years: the xAI-SpaceX merger, Tesla’s $2.9 billion solar equipment talks with Chinese suppliers, the 100 GW domestic solar manufacturing push, the Optimus humanoid robot program, and Starship’s development. TERAFAB is the capstone that ties them into a single coherent architecture — chips made on Earth, launched by SpaceX, powered by Tesla solar, run by xAI, and ultimately extended to the Moon.
“I want us to live long enough to see the mass driver on the moon, because that’s going to be incredibly epic,”Musk said during the presentation.

Rolls-Royce makes shocking move on its EV future
When Rolls-Royce unveiled its first all-electric model, the Spectre, in 2022, former CEO Torsten Müller-Ötvös declared the brand would cease production of internal combustion engine vehicles by the end of the decade.
Rolls-Royce made a shocking move on its EV future after planning to go all-electric by the end of the decade. Now, the company is tempering its expectations for electric vehicles, and its CEO is aiming to lean on its legacy of high-powered combustion engines to lead it into the future.
In a significant reversal, Rolls-Royce Motor Cars has scrapped its ambitious plan to become an all-electric manufacturer by 2030. The luxury British marque announced the decision amid sustained customer demand for traditional combustion engines and shifting regulatory landscapes.
When Rolls-Royce unveiled its first all-electric model, the Spectre, in 2022, former CEO Torsten Müller-Ötvös declared the brand would cease production of internal combustion engine vehicles by the end of the decade.
The move aligned with the industry’s broader push toward electrification, promising silent, effortless power befitting the “Rolls-Royce of cars.”
However, new CEO Chris Brownridge, who assumed the role in late 2023, has reversed course. “We can respond to our client demand … we build what is ordered,” Brownridge stated.
The company will continue offering its iconic V12 engines, which remain a cornerstone of its heritage and appeal to discerning buyers who appreciate the distinctive sound and character. He noted the original pledge was “right at the time,” but “the legislation has changed.”
While not abandoning electric vehicles entirely, the Spectre remains in production, with an electric Cullinan option forthcoming; the decision marks the end of a strict all-EV timeline. Relaxed emissions regulations and slowing EV demand, evidenced by a 47 percent drop in Spectre sales to 1,002 units in 2025, forced the reconsideration.
It was a sign that perhaps Rolls-Royce owners were not inclined to believe that the company’s all-EV future was the right move.
Rolls-Royce joins a growing roster of automakers reevaluating aggressive electrification targets.
Fellow luxury brand Bentley has pushed its full electrification from 2030 to 2035, while continuing to offer hybrids and ICE models. Mercedes-Benz walked back its 2030 all-EV goal, now aiming for about 50% electrified sales while keeping combustion engines into the 2030s. Porsche has abandoned its 80% EV sales target by 2030, delaying models and extending hybrids.
Mainstream giants are following suit. Honda canceled its U.S. EV plans, including the 0-Series and Acura RSX, facing a $15.7 billion hit as it doubles down on hybrids. Ford and General Motors have incurred tens of billions in writedowns, canceling models and pivoting to hybrids amid an industry total exceeding $70 billion in charges.
This trend reflects a pragmatic shift driven by infrastructure gaps, consumer preferences, and policy changes. In the ultra-luxury segment, where emotional connection reigns, automakers are prioritizing flexibility over rigid deadlines, ensuring brands like Rolls-Royce evolve without alienating their core clientele.

This optimistic timeline for tape-out—the stage where chip design is finalized before manufacturing—signals Tesla’s push to rapidly advance its silicon capabilities.
The announcement builds on progress with the predecessor AI5. Earlier in January, Musk announced that the AI5 design was “in good shape” and “almost done,” describing it as an “existential” project for the company that demanded his personal attention on weekends.
He characterized AI5 as roughly equivalent to Nvidia’s Hopper class performance in a single system-on-chip (SoC) and Blackwell-level as a dual configuration, but at significantly lower cost and power usage.
Elon Musk is setting high expectations for Tesla AI5 and AI6 chips
Musk highlighted that AI5 “will punch far above its weight” thanks to Tesla’s co-designed AI software and hardware stack, making maximal use of every circuit. While capable of data center training tasks, it is primarily optimized for edge computing in Optimus robots and Robotaxi vehicles.
For AI6, Musk envisions substantial gains. “In the same half reticle and same process node, we think a single AI6 chip has the potential to match a dual SoC AI5,” he explained.
The company is targeting ambitious nine-month development cycles for future chips, allowing rapid iteration to AI7, AI8, and beyond. AI5/AI6 engineering remains Musk’s top time allocation at Tesla, with the CEO calling AI5 “good” and AI6 “great.”
Samsung is expected to manufacture the AI6 chips, following deals worth billions, while AI5 will leverage TSMC and Samsung production. These chips will form the backbone of Tesla’s Full Self-Driving system, enabling safer and more capable autonomy, alongside powering dexterous movements in Optimus bots and efficient inference in expanding data centers.

Musk has also restarted work on the Dojo 3 supercomputer project now that AI5 is progressing. Long-term plans include in-house manufacturing via the Terafab facility.
By accelerating chip development with AI tools, Tesla aims to reduce dependence on third-party GPUs and deliver high-performance, energy-efficient solutions tailored to its ecosystem. Success with AI6 could mark a major milestone in Tesla’s journey toward full autonomy and robotics leadership, though timelines remain subject to manufacturing realities.
