Tesla’s Full Self-Driving v12.5 rollout on HW3 failed, what happens next?
Tesla’s rollout of Full Self-Driving v12.5 has failed so far, and owners want to know what happens next?
In 2016, Elon Musk announced that all future Tesla vehicles would come equipped with the necessary hardware for self-driving capabilities, even specifying “level 5 self-driving,” which implies the ability to operate autonomously under any conditions. However, shortly after, Musk acknowledged that Tesla might require more onboard computing power than initially thought, leading to the introduction of Hardware 3 (HW3).
Musk assured that HW3 would enable full self-driving (FSD) capabilities, promising retrofits for earlier models that had purchased the FSD package. Following this, Tesla introduced Hardware 4 (HW4), a more advanced onboard computer system, but did not offer retrofits for older models with HW3, maintaining that HW3 was sufficient for achieving self-driving through software updates.
Initially, Musk claimed that FSD improvements would first be optimized for HW3, suggesting that HW4 might lag behind by at least six months. However, Tesla reversed this approach with the release of FSD version 12.5, which was first deployed to HW4 vehicles. Musk explained that optimizing the software for the less powerful HW3 would take additional time, hinting at the limitations of HW3 in handling the latest software advancements towards unsupervised self-driving, a capability Tesla promised to HW3 owners since 2016.
This rewrite aims to streamline the narrative, focusing on the evolution of Tesla’s self-driving hardware and software, and the strategic shifts in deployment and optimization of FSD capabilities between HW3 and HW4.
Musk said that it would take ten days to adapt v12.5 to HW3.
In late August, about two weeks after Musk’s “10 days” had passed, we reported that Tesla started to push v12.5 to HW3 vehicles.
Not only was the update to HW3 late, but Tesla also confirmed that it was running a smaller model than on HW4.
On top of all that, now three weeks later, Tesla has yet to push v12.5 to the vast majority of FSD vehicles with HW3. Tesla appears to only have pushed v12.5.1.5 to some Tesla HW3 owners and it is now moving HW4 cars to v12.5.2.
Social media and Tesla forums are full of Tesla HW3 owners asking why they haven’t released a new update since v12.3.6 earlier this year despite Musk’s comments.
In its “AI roadmap” released last week, Tesla now claims that HW3 will get the same release as HW4 starting with v12.5.2 this month.
However, v12.5.2 is already in the consumer fleet for HW4 cars and v12.5.3 is already being tested in the beta fleet.
Electrek’s Take
This article is mainly to correct our article from last month that claimed Tesla was pushing v12.5 to HW3 since it turned out to be a very limited release.
Earlier this year, Elon said that Tesla was not compute-constrained for training FSD anymore. He also claimed that the training compute combined with v12’s full end-to-end neural nets would enable much faster software improvements.
And yet, the vast majority of HW3 owners have only received v12.3.6 this year.
That, combined with the fact that Tesla’s AI roadmap makes no mention of unsupervised self-driving whatsoever, and Tesla seemingly stopped promising it on new cars, has completely killed my hopes of Tesla delivering on its self-driving promises on HW3 cars and it has greatly limited by hopes of the same for HW4 cars.
I wouldn’t be shocked if Tesla fully shifts its self-driving strategy to the dedicated robotaxi, but I have no idea how they plan to make HW3 and possibly HW4 owners whole.
Germany’s largest offshore wind farm under construction, EnBW’s He Dreiht, just hit a big milestone: The first enormous turbine is now up in the North Sea.
He Dreiht – which means “it spins” in Low German – is using Vestas’s massive 15 megawatt (MW) turbines, the first project in the world to install them. Just one spin of one of the rotors can generate enough electricity to power four households for an entire day.
When it’s finished, He Dreiht will have 64 mega turbines cranking out 960 megawatts (MW) of clean power – enough to supply around 1.1 million homes. And it’s being built without any government subsidies.
EnBW, one of Germany’s major energy companies, has been working in offshore wind for more than 15 years, but He Dreiht is their biggest project yet. “It will play a key role in helping us to significantly grow our renewable energy output from 6.6 GW to over 10 GW by 2030,” said Michael Class, who heads up EnBW’s generation portfolio development.
The project is a win for Vestas, too. “With the installation of the first V236-15.0 MW, we have reached an important milestone for both the He Dreiht project and our offshore ramp-up, which helps Germany build a more secure, affordable, and sustainable energy system,” said Nils de Baar, president of Vestas Northern & Central Europe.
He Dreiht is located about 85 kilometers (53 miles) northwest of Borkum and 110 kilometers (68 miles) west of Helgoland. At peak times, more than 500 workers will be out at sea building the farm, using a fleet of more than 60 ships. EnBW’s offshore team in Hamburg is running the show.
The installation process is a major operation. The 64 foundations were already set in the seabed last year. Parts for the turbines are loaded onto the installation vessel Wind Orca in Esbjerg, Denmark, and shipped out in a 12-hour journey to the construction site. From there, the turbines are lifted into place. Meanwhile, crews are also working on internal wind farm cabling.
A partner consortium made up of Allianz Capital Partners, AIP, and Norges Bank Investment Management owns 49.9% of the shares in He Dreiht.

Tesla has released a quick update about its Tesla Semi factory in Nevada. It says that it is on track for volume production of the electric semi truck in 2026.
The Tesla Semi was first scheduled to go into production in 2019, but it has faced numerous delays.
Now, it appears that there is finally some momentum to bring it to volume production.
For the last two years, Tesla has been working to build a new factory next to Gigafactory Nevada, where it builds the battery packs and drive units for most of its electric vehicles built in North America.
Today, Tesla released a “progress update on the factory, confirming that it finished building and it’s now working on deploying the production lines:
Tesla had previously mentioned aiming for volume production by 2025, but it is now only talking about starting production toward the end of the year and ramping up next year.
The automaker reiterated its planned production capacity of 50,000 units.
We recently reported that an early Tesla Semi customer, Ryder, stated that the electric truck program is experiencing more delays and a price increase described as “dramatic.”
They now expect to take deliveries of their first trucks later in 2026 and said that the price has increased “dramatically,” leading them to scale back their pilot program from 42 to 18 Tesla Semi trucks.
When originally unveiling the Tesla Semi in 2017, the automaker mentioned prices of $150,000 for a 300-mile range truck and $180,000 for the 500-mile version. Tesla also took orders for a “Founder’s Series Semi” at $200,000.
However, Tesla didn’t update the prices when launching the “production version” of the truck in late 2022. Price increases have been speculated, but the company has never confirmed them.

Vietnamese solar panel maker Boviet Solar just opened the doors to its first US factory — a huge new PV module plant in Greenville, North Carolina.
The company dropped $294 million into the state-of-the-art facility, which will pump out Boviet’s Gamma Series monofacial and Vega Series bifacial solar panels. They’re using advanced PERC and N-Type solar cell tech, which basically means these panels are built to deliver higher efficiency and better performance across residential, commercial, industrial, and utility-scale projects.
The Greenville factory’s first phase is now online with an annual PV module output capacity of 2 gigawatts (GW). For Phase 2, which is scheduled to come online in the second half of 2026, Boviet will invest another $100 million to add 600,000 square feet and ramp up to another 2 GW. It will make high-efficiency solar cells.
Once both phases are complete, Boviet’s campus will cover more than 1 million square feet of manufacturing and R&D space. It’s one of the biggest clean energy manufacturing projects North Carolina has ever seen.
The jobs impact is significant, too. The first phase will create 460 skilled local jobs. Phase 2 is expected to add another 908, bringing the total to over 1,300 direct jobs, plus nearly 2,000 more indirect jobs across the region. That’s good news for Pitt County’s economy, real estate market, and workforce training programs.
“This facility is not just creating jobs, but creating opportunity, innovation, and a stronger foundation for eastern North Carolina,” said Senator Kandie Smith. Governor Josh Stein added that Boviet Solar’s move shows how North Carolina is leading the way in clean energy growth.
