Tesla’s Model 3 and the death of plug-in hybrids: ‘Full electric is a much more elegant solution’
Tesla took a big bet when it decided to launch the Model 3. Being a vehicle designed for the mass market, the sheer scale of the sedan’s production was something that Tesla has not dealt with before. It took more time than expected and a trip through “production hell,” but the Model 3 has now been ramped, with Elon Musk noting that producing 5,000 of the vehicles per week is currently no big deal for Tesla.
The market’s reception to the Model 3 has been encouraging. The vehicle has been performing well in the United States, ranking among America’s best-selling passenger cars. In September alone, the Model 3 became the 4th best-selling car in the US based on sales volume. Based on revenue, the Model 3 was even more impressive, ranking first among passenger cars sold in the country. Tesla does not seem to be planning on pulling back from its Model 3 push either, as the electric carmaker has started rolling out exhibits of the vehicle to Europe and Asia this month.
Amidst the evident success of the Model 3 and Elon Musk’s high-stakes bet on the electric sedan, another class of vehicles has begun to show notable signs of a decline — the plug-in hybrids. Plug-in hybrid electric vehicles (PHEV) are equipped with both an electric motor and an internal combustion engine. Popular cars in this class include the Chevy Volt, with its all-electric range of up to 53 miles, and a total range of 420 miles with a full battery and a full tank of gas.
PHEVs have mostly served as the “gateway” vehicles for customers looking to make the jump to electric transportation. Being equipped with a gasoline engine, owners need not worry about any of the initial drawbacks of pure EVs, such as limited range. Plug-in Hybrid and Electric Vehicle Research Center director Gil Tal noted to Bloomberg that in a way, PHEVs are like the “training wheels” of the electric car movement. That said, Tal noted that as practical, capable EVs like the Model 3 emerge, consumers might simply skip PHEVs and adopt all-electric cars instead.
“A full electric (car) is a much more elegant solution. It’s very simple to build and very low maintenance. It’s just a much more simple story. Plug-in hybrids are just the training wheels in the industry’s preparation for electric cars,” Tal said.
The death of plug-in hybrid electric vehicles became more real recently, with GM announcing that it was closing several of its plants across the United States and Canada. Among these plants was GM’s oldest factory at Detroit-Hamtramck, which produces the Volt. In a later statement, GM confirmed that it would be discontinuing the production of the Volt, with the company focusing on developing all-electric cars like the Bolt EV instead.

In a way, the apparent death of the PHEV seemed to have been predicted by Elon Musk eight years ago. In a statement to the media during the opening ceremony of the Fremont factory, Musk likened PHEVs to amphibians during the process of evolution. And just like amphibians, Musk noted that the number of PHEVs would likely decrease as the market moves into the full-electric era.
“(PHEVs are) similar to an amphibian. In the transition from the oceans to land, initially, there were a lot of amphibians. Now there’s not that many amphibians. So the only reason you’d ever need that gasoline engine is if the battery pack does not have enough range, if the recharge times are really slow, and all those things will get solved. So there’s a medium-term role for a plug-in hybrid, but in our view, not a long-term role. I think there’s a role for plug-in hybrids today and there’s a role for electrics, but I think long-term, it all goes electric.”
The seemingly impending death of the plug-in hybrid is not just the result of electric cars like Tesla’s Model S, 3, and X. Earlier this year, a Forbes report earlier this year noted that the efforts (or lack thereof) of manufacturers such as GM are partly to blame for the decline of PHEVs. Inasmuch as the Volt was warmly received by owners and well-reviewed by critics, for example, the vehicle remained a rare sight among GM’s dealerships across the United States. GM’s TV advertising campaigns have not featured the Volt, or its all-electric sibling, the Bolt EV, either.
That said, GM appears to be taking its EV initiative seriously this time around. Earlier this month, for one, VP of global strategy Mike Ableson boldly declared during a press conference that GM is looking to “lead the industry in EVs sometime in the next decade or so.” The next years will determine if these words will be true.

Tesla reveals Optimus Academy, where robots teach themselves
Tesla has begun building production quality Optimus robots in Fremont and revealed its training plan.
Tesla has started building Optimus on the high volume line it set up inside its Fremont factory, and the company says the robots coming off it are the first that meet the bar for a real product. “The bots coming off this line are the first production-quality bots that we have manufactured,” Tesla wrote in its third quarter shareholder letter, adding that it has “proven that the current manufacturing process for Optimus is suitable for a commercial product.”
The line sits in space that built the Model S and Model X until this spring. Tesla cleared the old vehicle line in 46 days, as Teslarati reported in July, to make room for robot production sized for one million units a year. On Wednesday’s earnings call, Elon Musk said most of the equipment for that capacity is already in Fremont, with output set to climb toward roughly 20,000 robots a week as the line ramps.
Musk described the ramp as a classic S curve. “The growth of Optimus is an S curve, but the initial curve is a shallow slope,” he said. The team is now refining the robot’s AI, electromechanical design, reliability and service life, and Musk expects that work to be finished by the end of next year, when Tesla plans to start delivering Optimus to outside companies for dangerous, repetitive and around the clock jobs.
The most interesting part of the call was how Tesla plans to teach the robots. Its cars send real driving data back to the AI team from millions of vehicles, but Optimus has no fleet like that yet. “A big difference with Optimus versus the cars is we don’t have this vast fleet of cars from which we can gather training data,” Musk said. Tesla’s answer is an Optimus Academy, where 10,000 to 20,000 robots will practice a wide range of tasks and feed what they learn into the next version of the model. Every unit off the Fremont line becomes a source of that training data.
Smarter hardware is on the way too. Tesla plans to put its AI5 chip into Optimus next year, and Musk said a new Optimus video should arrive within one or two months showing the robot completing tasks driven by AI rather than preprogrammed motions. He took aim at rival humanoid demos that only run scripted routines, saying those would not hold up in the real world.
The supply chain is lining up behind the program. In September, Tesla certified Tuopu, Joyson and Sanhua as mass production partners for Optimus components. A far larger Optimus factory is also rising at Giga Texas, where drone footage from Joe Tegtmeyer showed the steel frame nearing completion, and Musk has pegged that plant’s long term target at 10 million robots a year.
Tesla executives also said Optimus production costs are trending toward the expected manufacturing cost of Cybercab, a sign the robot is being engineered for volume from the start. The hands remain the toughest piece of the design, a point Musk also made at the X Takeover event earlier this month, as Teslarati covered at the time, and that is where much of the current engineering effort is focused.

The Starship moon landing number NASA and Elon Musk can’t agree on
Musk disputes NASA estimate of 22 Starship launches for Moon landing, predicting 6 to 8.
Elon Musk is disputing a new NASA safety panel estimate of how many Starship launches it will take to put astronauts on the Moon, saying the real number will be less than half the panel’s figure.
On Thursday, NASA’s Aerospace Safety Advisory Panel held its quarterly public meeting. Panel member Charlie Precourt, a former NASA astronaut, flagged the fueling process for SpaceX’s lunar lander as a major risk for Artemis IV, the mission planned to land a crew on the Moon in 2028. “We need to keep our eyes on numerous required fuelings for the lander,” Precourt said, according to Ars Technica. “I think the last estimate is around 22 flights.”
Ars Technica’s Eric Berger posted the comment on X, and Musk replied. “That’s way too high,” Musk wrote. “Actual number will be more like 6 to 8.”
The disagreement comes down to a basic problem with sending a ship as large as Starship to the Moon. Starship burns nearly all of its propellant just reaching Earth orbit, so it cannot continue on to the Moon without stopping for a refill. SpaceX’s answer is a gas station in space. First, a Starship that works as a storage tank, called a depot, is launched into orbit. Then a series of tanker Starships launch one at a time, dock with the depot and pump their leftover propellant into it. Once the depot is full, the lunar lander version of Starship launches, docks, fills up and heads for the Moon.
Every tanker trip is its own full rocket launch, which is why the count matters. More launches mean more time, more cost and more chances for something to go wrong before astronauts ever leave Earth. Berger estimated that even if SpaceX reaches twice weekly Starship launches by the end of 2027, filling a depot at the panel’s number would still take roughly three months.
How many tankers are needed depends mostly on how much propellant each one can carry to orbit and how much is lost along the way. Starship’s fuel and oxygen are stored at extremely cold temperatures, and some of it slowly boils off while waiting in orbit. More is lost in each transfer. NASA appears to be working from what Starship can lift today, while Musk’s range assumes a more capable rocket.
Musk has pushed back on higher counts before. In 2021, after a government document suggested 16 launches, he called that “extremely unlikely” and said eight tankers would be the most required.
Much of the answer depends on hardware SpaceX has not finished flying. As Teslarati noted earlier this year, the company plans to carry out the refueling process with its upgraded V3 Starship, and Precourt described Artemis IV as carrying “a large number of firsts.” He also praised NASA Administrator Jared Isaacman’s team for working to clear obstacles for both SpaceX and Blue Origin, whose Blue Moon lander does not rely on orbital refueling for its first mission.

Tesla’s secretive “Project Crystal Sun” gets a big green light in Texas
Fort Bend County approved four incentive agreements Thursday for Tesla’s proposed $10.1 billion solar factory.
Fort Bend County commissioners on Thursday approved a package of tax incentives for Tesla’s proposed $10.1 billion solar cell factory near Needville, Texas, giving the company one of the last local approvals it needs before it decides where to build. All four Tesla agreements passed 4 to 0.
The votes covered a property tax abatement inside Reinvestment Zone No. 34, a Chapter 381 economic development agreement, a foreign trade zone non-objection paired with payments in lieu of certain taxes, and a separate payment in lieu of taxes “true up” agreement, according to agenda notes from the Fort Bend Commissioners Court meeting.
The project, known internally as “Project Crystal Sun,” would make solar cells and finished modules on roughly 3,000 acres near FM 762 and FM 1994, south of the Brazos River. As Teslarati reported when the filing first surfaced in August, Tesla’s application under the state’s JETI Act splits the investment into $1.5 billion in real property and $8.6 billion in equipment, with 9,712 permanent jobs projected by 2033 and commercial operations targeted for the first quarter of 2029. The plant would handle the full chain from ingot and wafer production through cell testing.

Thursday’s approval does not lock in the site. Tesla has told the Texas Comptroller it is still weighing other locations, and site selection adviser David Dennison told Lamar Consolidated ISD trustees in September that the race had narrowed to Fort Bend and one out of state rival with a “very compelling package,” according to the Houston Chronicle. Tesla hopes to decide before the end of 2026, and the incentives still need sign off from the Comptroller and the Governor’s office.
Local officials have now done nearly everything within their control. Commissioners created the reinvestment zone in an August 24 special meeting, with Interim County Judge Daniel Wong formally withdrawing himself over his engineering firm’s past work with Tesla. Lamar CISD trustees voted 7 to 0 on September 15 to advance a JETI agreement that would tax Tesla’s qualifying property at 50 percent of its value for maintenance and operations from 2029 through 2038.
The plant lines up with a target Elon Musk set on Tesla’s Q4 2025 earnings call in January, when he said the company would “work toward getting 100 GW a year of solar cell production, integrating across the entire supply chain from raw materials all the way to finished solar panels.” In March, Tesla was reported to be negotiating a $2.9 billion purchase of Chinese solar manufacturing equipment bound for Texas. The Houston area already hosts Tesla’s Megafactory in Brookshire, where Megapack 3 production has started. Tesla said on its Q3 call that Megapack supply for 2027 is nearly sold out, and Musk wrote on X Thursday that the company is “increasing production of Megapacks as much as possible,” as demand from data centers climbs.
