Tesla Semi gets ‘peppy and quiet’ hydrogen fuel cell competitor from Kenworth-Toyota
With support from the California Air Resources Board, Japanese auto giant Toyota and truck maker are collaborating to develop and build a limited run of hydrogen fuel trucks. The vehicles, which are Kenworth T680 trucks modified with Toyota’s hydrogen fuel cell powertrains, are expected to drive on routes around Los Angeles and further inland to San Bernardino. The actual specs of the vehicles have not been announced by either company, but the range of the hydrogen fuel cell T680 trucks are said to be 300 miles in “normal drayage operating conditions.”
Toyota and Paccar, the parent company behind Kenworth, took the wraps off the first hydrogen fuel cell long-hauler at this month’s Consumer Electronics Show in Las Vegas. The vehicle, which is classified as a Class 8 truck, stands to be a possible competitor for upcoming all-electric trucks like the Tesla Semi in the future. In a statement to CNBC, Brian Lindgren, Kenworth’s director of research and development, noted that utilizing hydrogen as a source of propulsion makes more sense for Class 8 vehicles than batteries, which power vehicles like Tesla’s all-electric long-hauler.
“We believe that carrying energy in the form of hydrogen for heavy-duty Class 8 trucks makes more sense than carrying it in batteries because the trucks can be refilled faster and offer longer range,” he said.
Lindgren’s point about faster refilling times for hydrogen fuel cell vehicles is quite justified, considering that a passenger car such as a Toyota Mirai could refill its tank with around 300 miles of range in roughly five minutes. That’s significantly faster than Tesla’s Superchargers, which are capable of charging roughly 200 miles of range in 30 minutes. Larger vehicles such as the hydrogen-electric Kenworth T680 trucks would likely take longer to refill than a passenger car such as the Mirai, but there’s a good chance that the long-hauler could still refill its tank faster than the Tesla Semi could charge its batteries, even if it is plugged into the upcoming Megacharger Network.
Toyota-Paccar’s Kenworth T680 hybrid fuel cell trucks caught the attention of some CES attendees due to the vehicle’s silent operation, which is nearly comparable to an all-electric truck. Lindgren, for his part, noted that drivers who have operated the truck actually appreciated the silence of the vehicle. “Drivers like these trucks because they are peppy and quiet,” he said.
Andy Lund, the Toyota chief engineer on the project, further stated that the hydrogen-electric trucks would have the same payload capacity as a diesel rig. Unlike its fossil fuel-powered counterparts, the hydrogen fuel cell Kenworth T680 long-haulers would only require a four-speed transmission, which is far simpler than the 18-gear transmissions usually fitted on Class 8 diesel trucks.
If there is one thing that would probably go against Toyota and Paccar’s hydrogen trucks, though, it would be their fuel efficiency. Kenworth’s director of research and development noted that the prototype trucks currently consume hydrogen at roughly the same rate as present diesel trucks, at around 5-7 mpg. The only advantage of the vehicles, of course, is that the trucks would only produce water vapor from their exhausts. This is a substantial advantage, considering that the trucking industry accounts for about 23% of carbon emissions from transportation in 2016, according to the Environmental Protection Agency.
That said, this would be something that Tesla could capitalize on. During the electric long-hauler’s unveiling, Musk noted that the Semi would cost operators $1.26 per mile to run, less than the standard $1.51 per mile that diesel-powered vehicles cost. Musk’s estimate has been met by skepticism by veterans of the trucking industry, but if the Tesla Semi’s operating costs stay true to the CEO’s estimate, then the vehicle would most certainly give itself a notable advantage over diesel and hydrogen-powered rivals when it starts operating on America’s roads.
Hydrogen fuel cells remain a polarizing solution for sustainable transportation. Elon Musk, for one, has openly discussed his dislike for hydrogen-electric transportation. In a statement to Autocar in 2014, for one, Musk went so far as to describe hydrogen fuel cell systems as “mind-bogglingly stupid.”
“They’re mind-bogglingly stupid. You can’t even have a sensible debate. Consider the whole fuel cell system against a Model S. It’s far worse in volume and mass terms, and far, far, worse in cost. And I haven’t even talked about hydrogen being so hard to handle. Success is simply not possible. Manufacturers do it [FCEVs] because they’re under pressure to show they’re doing something ‘constructive’ about sustainability. They feel it’s better to be working on a solution a generation away rather than something just around the corner. Hydrogen is always labeled the fuel of the future – and always will be,” Musk said.
Elon Musk initially announced that the Tesla Semi would start production sometime in 2019. That said, later statements from Tesla’s head of investor relations Martin Viecha suggested that the electric car maker would “earnestly” start producing the Semi by 2020.

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.
Inside Tesla’s secretive $10 Billion “Project Crystal Sun” filing
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.

Tesla is building its own maps to fix Navigation issues
Tesla revealed plans to develop its own maps internally to fix Navigation issues and give owners more control over their routing.
On the company’s Q3 2026 Earnings Call, a question was asked about FSD Navigation issues, particularly speed limit recognition, parking, and routing. These are issues that surface from version to version and seem to be seriously challenging for Tesla’s AI team to resolve.
Tesla’s Head of AI, Ashok Elluswamy, said in response to the question:
“You’re totally right that we shouldn’t be depending on external people’s maps. So we are building our own maps, but not like the same way as OneMoreMap. We are building an entirely new architecture with essentially AI-based mapping and navigation.”
He continued:
“It’s going to be super awesome. It’s going to be integrated with voice. You can talk to it, ask for different routes. It’s going to learn your personalized preferences, plus the fleet preferences. The collective intelligence of all the cars is going to flow into making the maps and navigation super cool.”
Elluswamy said this issue should be confronted, and the mapping should be available for people by the time the v15 release starts deploying to customers.
“And over the next several months,” he added, “it’s just going to take over all of the navigation functions, parking, destination handling. And it will know you better than you know yourself in some regard for the driving task, and then handle it fully.”
Tesla Summon got insanely good in FSD v14.3.2 — Navigation? Not so much
Navigation is perhaps the most notable complaint with FSD, and although it has gotten better, it is still flawed. Much of the time, FSD will take people on routes that are not preferred by the driver, but Tesla tried to combat this with a routing feature in the Summer 2026 Update.
Tesla currently relies on Google for map data, but it is sort of counterintuitive to believe the company would rely on a third party for this. These improvements will be welcome, as routing and navigation have been such a pain point for so many owners for so long.
