Tesla’s new self-driving (HW4) computer leaks: Here’s a teardown
Tesla’s new self-driving computer, Hardware 4.0 (HW4), has leaked as the automaker appears to be already building some cars with the upgraded system.
Here’s a first teardown.
We have known that Tesla has been preparing an upgrade to its Autopilot/self-driving hardware for a bit now.
Most notably, Tesla filed with the FCC to add a new radar on its vehicles and said that it planned to start marketing it in January. A new radar would mean that Tesla plans to update its sensor suite for Autopilot and self-driving.
We have also heard that the automaker is changing its cameras, according to a filing with Chinese regulators.
Finally, Tesla is expected to produce a new self-driving computer to merge all those new sensors into a more powerful computing platform.
All these hardware changes have been stressful for Tesla owners since the automaker has been promising that all its vehicles built since 2016 have all the hardware necessary to achieve self-driving through software updates.
It turned out not to be true as Tesla needed a more powerful computer (HW3), but it did supply the retrofit to existing owners for free.
Now CEO Elon Musk confirmed that Tesla will not provide retrofit to HW4, but he said that the automaker still plans to deliver on its self-driving promises with HW3 and that HW4 will only push the performance higher.
Tesla Autopilot/Self-Driving Hardware 4.0
The teardown comes courtesy of Green The Only, a well-known Tesla hacker and tinkerer who has consistently revealed a lot of new information about Tesla vehicles by hacking the automaker’s software and tearing down its hardware.
In this case, he managed to get his hands on a new HW4 computer from a new Model X vehicle. We won’t go into details about how.
There are some indications that Tesla is implementing the new hardware suite in the Model X first with the automaker having just put up for sale its display and test drive fleet, which Tesla generally does later in a quarter. It could mean that Tesla is liquidating its Model X units in preparation for the new hardware.
Green started the teardown by confirming what Musk recently said: Don’t expect a retrofit.
Tesla’s self-driving computer is combined with its infotainment computer, which has also been updated with this HW4 upgrade.
Green said about the change:
Infotainment was reworked compared to current units. The GPU is now on the same board, so no more GPU daughterboard. This makes the whole unit thinner, otherwise no changes there – same 256G NVMe and 16G RAM, same AMD CPU and GPU.
As for Tesla’s actual HW4 computer, Green sees less improvement than what was hoped:
He did note that there are some improvements in security. Musk mentioned hackability of self-driving vehicles was a top concern at Tesla.
On the downside, the hacker’s own measurement shows that the new board has a higher power consumption than HW3 when idle.
Green noted that Tesla has also made improvements to the redundancy of the system, which is obviously important in a self-driving vehicle:
Redundancy is the name of the game this time? The board is mostly symmetric, with identical power connections on each side. There are even two network links to infotainment. Yet… if you unpower the A side, that kills the network switch and the link is lost. Still the improvements are there.
Now for what people have all been waiting for – the sensors.
Obviously, this is the computer and not the sensors, but the connectors can give us more information about the new sensors in HW4.
Now Tesla has been moving to a vision-based (cameras) approach and it has made a big deal of removing its radar and ultrasonic sensors.
There’s good news with HW4. Tesla appears to be including more cameras. There are currently 8 cameras in Tesla’s hardware suite, but now the new computer has connectors for 12 cameras, although one connector is marked as “spare.”
So we are talking about likely 11 cameras. Now as for the camera placement, it looks like all the current cameras remain other than a two camera setup in the windshield rather than the current three-front-facing camera setup.
While the information is hard to decrypt, Green sees indications that Tesla might have added cameras in the bumpers:
What’s SVC you might wonder? According to Tesla EPC, SVC is a bumper cover. So I’d guess these are bumper cameras. There’s a huge blindspot upfront on legacy cars up front (welcome to the legacy camp, Plaid owners!), so front bumper camera and two in the (rear?) bumper corners for cross traffic alerts (esp. with pillar moved forward)?
Green also found a connection for a new GPS module with a triband antenna:
The hacker noted about the new GPS unit:
The unit itself is big and unmarked, so who makes it is unknown, I would not be surprised if it’s somewhat custom Tesla thing. They carry a bootloader for it in firmware.
Finally, Green also found evidence of Tesla’s integrating a radar back into its sensor suite:
Musk told Electrek in June of last year after Tesla stopped using its radar:
The probability of safety will be higher with pure vision than vision+radar, not lower. Vision has become so good that radar actually reduces signal/noise.
However, the CEO also added that Tesla might still use radar if it had a “very high-resolution radar”:
A very high resolution radar would be better than pure vision, but such a radar does not exist. I mean vision with high res radar would be better than pure vision.
We saw some indications of Tesla working on that. We previously reported on Tesla looking to add a new “4D” imaging radar with twice the range of its previous radar.
That high-resolution radar was codenamed “phoenix,” so it might be the very radar that makes it to the new hardware suite.
It’s not clear when Tesla plans to make the new HW4 official, but the timing of the March 1 Investor Day makes it a likely contender for an official announcement.

The Anthbot Genie 3000 brings automated mowing tech to your backyard without the need for old-fashioned perimeter wires. It has GPS-grade precision and AI-powered vision, and I got to check out how well it works. With a mix of impressive strengths and a few growing pains, it’s a compelling entrant in the smart‑lawn space worth a closer look.
Setup and specs
There are a few models in the lineup, ranging from $699 to $1,399. I was testing the larger battery version since my parents have some land, and the extra battery makes quicker work of larger plots.
Unboxing the Genie, you’ll find the mower, charging base, RTK GPS station with pole (the mushroom-looking thing), power cables, spare blades, tools, and a quick‑start guide. Unlike some electronics I’ve set up, the quick start guide was actually really well laid out and useful.
The three models in the Genie line:
- 600 – up to ~600 m² (0.22 acres)
- 1000 – up to ~2,000 m² (0.49 acres)
- 3000 – up to ~3,600 m² (0.89 acres)
The 3000 bumps up the battery to 10 Ah, but they all share the same core specs: a 20 cm (7.9 “) cutting width, adjustable electric deck height (30–70 mm or 1.25 to 2.75 inches), IPX6 waterproofing, and the ability to handle steep slopes, though my Florida testing didn’t exactly put the hill-climbing claims to the test.
Navigation and mapping
This is where the Genie shines. The combo of full‑band RTK GPS plus four AI‑driven cameras enables wire‑free navigation. That means no boundary cables, freeing the mower from the biggest problem with old-fashioned alternatives. Instead, GPS-based boundaries set the limits and your mower is free to do its thing without worrying about a boundary wire breaking one day and your mower making a run for the county line.
Mowing occurs in mostly clean, straight lines, avoiding the chaotic randomness older robot mowers often exhibited. It did seem to have a few areas where it missed on the first run, though it actually went back and got them (mostly), and that got better on subsequent mowing sessions.
Obstacle avoidance is solid. Within its 300° camera field, it claims to detect upwards of 1,000 common objects, sidestepping everything from garden hoses to pets. For me, the occasional potted plant or other obstruction in the yard was pretty easy for the robot to spot.
There are even headlights that seemed quite bright at night (and the very quiet electric mowing meant that it doesn’t disturb anyone when mowing at night).
App and smart features
The Genie app is used for setup and lets you define many different mowing zones, draw no‑go zones, tweak cutting height, schedule operations, and monitor battery and progress live, even when you’re away. During setup, I did find that I had to move the mower closer to my router for it to successfully update its firmware, but afterwards it was fine just stealing some signal that leaked out the walls of the house. I guess for the bigger download, it wanted the stronger signal closer to the router.
There are also anti‑theft features, including device‑binding to your Wi‑Fi and account, and a PIN lock so that someone else can’t just take and use your robot. That may be a concern if you live in an area with lots of neighbors, but out in the boonies, I don’t think anyone is looking for robo-mowers.
Performance and real-world use
The first thing that impressed me about the Genie is how quiet it is. They say it runs at about 58–66 dB, whisper-quiet under normal conditions. You can literally hear the individual grass blades being cut – something I’ve never heard before in all my gasoline-powered mowing years.
The battery seems to last for around 450 to 500 m2 of mowing, or around 3-4 hours, depending on how thick the grass is in that section. Then it returns home to recharge and starts up again where it left off. The mowing width might seem hilariously narrow, just 7.9 inches. But since you’re not actually the one mowing, it doesn’t really matter. My robotic vacuum also has a very narrow vacuum width, but I’m not the one walking around vacuuming, so what do I care? The passes all seem straight and good-looking, so you still get the nice lawn stripes look, though they’re a bit narrower.
The robot performs quite well, and it fulfills my goal which was to make it easier on my 70-year-old parents. It’s not perfect at edging, but if my dad can do 3 minutes of cleaning up along the fence line once in a while instead of an hour of lawn mowing, that’s a major improvement for him.
I don’t know how long these little razor-style blades will last, though they’re pretty cheap and easy to swap out. And I do wish the company made the cable longer between the RTK mushroom and the mower’s base station, so you can get the RTK out a bit further if you need it, but I found a spot that seemed to work for optimal signal for me.
I would say that the Genie 3000 is great for anyone who wants an easy setup process and wire-free operation. There’s no boundary wire to install or to check for breaks. It just works (as long as you have a clear view to the sky for the satellites). But if you’re trying to mow several acres, this little guy probably isn’t the one for you. Anything up to around 3/4 of an acre is where it will shine.
Now I just need to find something that can handle several acres in the pasture behind the backyard…

A new review of US Energy Information Administration (EIA) data by the SUN DAY Campaign reveals that solar delivered almost 9% of US electricity in the first half of 2025. Wind and solar combined produced just over one-fifth of the country’s electricity, while renewables as a whole hit nearly 28%.
Solar’s record-breaking growth
EIA’s latest monthly Electric Power Monthly report (with data through June 30, 2025) confirms that solar kept its streak as the fastest-growing major source of US electricity. In June 2025 alone, solar soared. Utility-scale solar power plants cranked out 30.1% more electricity than in June 2024, while rooftop and other small-scale solar systems grew by 10.5%. Combined, solar generation jumped 25% year-over-year and made up 10.2% of US electricity that month.
Looking at the first six months of 2025, utility-scale solar expanded by 37.6%, and small-scale systems rose 10.7%. Together, they grew nearly one-third (29.7%) compared to the same period in 2024. That meant solar provided 8.7% of all US electricity in January-June, up from 6.9% the year before.
That’s a milestone: Solar is now producing almost 45% more electricity than hydropower (6.0%), and it’s generating more than hydropower, biomass, and geothermal combined.
Wind is still a front-runner
Wind turbines supplied 11.6% of US electricity in the first half of 2025 — a 2.4% boost compared to the same time in 2024. Wind’s output was almost double hydropower’s contribution.
Wind + solar are beating coal and nuclear
Together, wind and solar accounted for 20.3% of total US electricity in the first half of 2025, up from 18.6% last year. That’s a bigger share than coal or nuclear. In fact, wind and solar generated 25% more electricity than coal and 15.6% more than nuclear over the same period.
Renewables overall are surging
All renewable sources combined – wind, solar, hydropower, biomass, and geothermal – generated 27.7% of US electricity from January through June 2025, up from 26.1% a year ago. Their output grew three times faster than total US electricity generation overall (9.2% vs. 3.0%). Renewables are now second only to natural gas, whose generation actually dropped 3.7% in the first half of the year.
Ken Bossong, executive director of the SUN DAY Campaign, added that this growth happened before the passage of the Trump/Republican “megabill,” which could slow future renewable expansion. “Nonetheless, EIA notes that US developers expect half of new electric generating capacity to come from solar in 2025 and another 13% from wind.”

The new and improved Hyundai IONIQ 5, or the hot-selling Chevy Equinox EV? Which electric SUV makes the smarter lease? Here’s the rundown.
Over 607,000 electric vehicles were sold in the US in the first half of 2025, thanks to some big discounts. Many automakers are currently offering generous savings, as Trump’s “One Big Beautiful Bill” is set to end federal EV incentives at the end of September.
According to Cox Automotive’s latest EV Market Monitor report, EV incentives reached a record of nearly $8,500 in June, or about 15% off the average transaction price (ATP).
That’s more than double the incentives offered on gas-powered vehicles. Seven electric vehicles had an ATP below $40,000, including the Chevy Equinox EV. The Equinox EV was the top-selling EV in the price range.
Starting at just $34,995, GM calls it “America’s most affordable 315+ range EV.” The electric Equinox has already propelled Chevy to become the number two EV brand in the US behind Tesla.
Through the first half of the year, the Chevy Equinox EV accounted for nearly a third of GM’s electric vehicle sales. And it could have sold even more. A dealer in California reached out to Electrek, claiming they had to wait over a month to receive Equinox EV models. It’s now on track to be among the top three selling EVs in the US.
Which EV to lease: Chevy Equinox EV or Hyundai IONIQ 5
With leases starting at just $289 per month, it’s no wonder the electric SUV is flying off the lot. The offer is for 24 months with $3,909 due at signing.
Alternatively, you can opt for 0% APR financing for 60 months, which Chevy is offering on all 2025 electric vehicle models.
