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.

Isuzu is giving Red Bull electrified wings – the iconic drinks company is officially the first to put the production version of its new-for-2025 Isuzu NRR-EV medium duty electric box truck to work in North America.
Deployed by Red Bull North America, these first-ever customer Isuzu NRR-EV medium duty trucks are busy delivering cans of Red Bull products throughout Southern California with zero tailpipe emissions, marking the first time the best-selling low-cab/cabover box truck brand in the US can make such a claim.
“Today marks a major milestone for the industry and for us. Watching the NRR-EV evolve from a concept to a viable operating product is a big deal,” explains Shaun Skinner, President of Isuzu Commercial Truck of America. “Our teams and our clients have put so much time and effort into making this happen, and it speaks to our teamwork and dedication to more sustainable transportation solutions. It is no longer just a plan, we have zero-emission trucks serving our customers’ needs!”
The NRR-EV is available with a number of different battery configurations, ranging from three 20 kWh battery packs (60 kWh total) up to nine 20 kWh battery packs, with five and seven pack options in between. The nine-pack version is good for up to 235 miles of range with a 19,500 lb. GVWR. The batteries, regardless of configuration, send power to a 150 kW (200 hp) electric motor with 380 lb-ft. of torque available at 0 rpm.
For “Red Bull” duty, the Isuzu trucks ship with a 100 kWh total battery capacity, and are fitted a lightweight, all-aluminum 6-bay beverage body, the vehicle’s design maintains its cargo capacity. The NRR-EV’s 19,500 lb. GVWR (Class 5) chassis, combined with the lightweight body and “big enough” battery spec provides Red Bull’s delivery drivers a hefty, 9,000 lb. payload.
Isuzu began assembling NRR-EV trucks at its Charlotte, Michigan assembly plant in August 2024. Customer deliveries are set to begin nationally in Q1 of 2025.
Electrek’s Take
Isuzu’s N-series trucks are everywhere – and for good reason. They’re dependable, they’re affordable, and they have a nationwide network of GM dealers supporting them. I am a huge fan of these trucks, and can’t wait to sample the electric version from behind the wheel.

Hyundai is gearing up to launch its first all-electric minivan. Production is set to begin next year, and the EV minivan is expected to play a key role in its global expansion. Here’s what to expect.
Hyundai will launch its first EV minivan in 2025
The Staria is Hyundai’s successor to the Starex, its multi-purpose vehicle (MPV), launched in 2021. Like its replacement, the Staria is offered in a minivan, minibus, van, pickup, and several other configurations like limousines and ambulances.
Although the Staria was launched with only diesel and gas-powered powertrain options, Hyundai added its first hybrid model in February.
Hyundai will introduce the Staria Electric, its first electric minivan, next year. In March, Hyundai unveiled its new ST1 electric business van, which is based on the Staria. However, the minivan will get its own EV model in 2025. The ST1 is Hyundai’s first commercial EV. It’s available in refrigerated van and basic chassis cab options.
Hyundai is already building gas-powered and hybrid Staria models at its Ulsan plant in Korea, but it is preparing to begin producing the EV version.
According to the Korean media outlet Newsis, sources close to the matter on Friday said Hyundai will begin converting a production line (Line 1) at its Ulsan Plant 4 for Staria Electric around January 25, 2024.
The expansion is part of Hyundai’s broader plan to introduce 21 electric vehicles by 2030, accounting for over 2 million in sales.
A report from The Korean Economic Daily in June claimed Hyundai would expand Staria EV production into Europe starting in the first half of 2026. European-made models will be sold domestically and overseas, like in Australia and Thailand. Hyundai aims to sell 15,000 to 20,000 of the EV model annually.
The Staria Electric will be powered by Hyundai’s fourth-generation 84 kWh EV batteries and will have over 10% more capacity than the ST1.
Hyundai sold 37,769 Starias through the first 11 months of 2024. Last year, Hyundai Staria sales reached 39,780, including domestic and export sales. By the end of the year, Staria sales are expected to exceed 40,000 for the first time.
Hyundai’s sister company also has big plans to expand its commercial business with a new lineup of EVs based on its PBV (Platform Beyond Vehicle). Its first electric van, the PV5, was spotted earlier this year as a potential Volkswagen ID.Buzz challenger.

Just a year after it hit the 1 million electric mile mark, Schneider National ($SNDR) and its unmistakable orange semi trucks have thrown down the gauntlet – adding more than 5 million miles to its BEV tally and crossing the 6 million electric mile mark!
The company says this latest all-electric milestone means Schneider has cut more than 20 million pounds of harmful carbon emissions. A total it says is equivalent to removing more than 2,100 gas-powered passenger cars from the road.
“Reaching 6 million zero-emission miles is a testament to our steadfast dedication to sustainability and innovation,” said Schneider President and CEO, Mark Rourke. “Leading the way in adopting electric vehicle technology not only benefits the environment but also serves as an example of the broad service capabilities and flexibility we can offer to customers.”
Schneider operates one of the largest fleets of Freightliner eCascadia electric semi trucks in the country, with fully 92 of the BEVs deployed (so far). The trucks have been operating in and around the ports of Southern California, where they have significantly reduced emissions and contributed to cleaner air quality while reliably transporting freight and saving SNDR money.
“Schneider is a great example of the kind of forward-thinking entrepreneurship our industry needs,” says David Carson, Senior Vice President, Sales and Marketing at DTNA. “They’ve achieved over 6 million zero emission miles, which is a reminder for us all to keep working on overcoming challenges together on the path to zero emissions. At DTNA, we’re committed to the shift to zero emissions, alongside pioneers like Schneider, who are showing us what’s possible.”
Fifty of Schneider’ 92 eCascadias were funded by JETSI – a California-wide initiative working to reduce greenhouse gas emissions. Of the remaining 42 five are jointly funded by the EPA’s FY18 Targeted Airshed Grant, seven are funded by the Volkswagen Environmental Mitigation Trust, and 30 are funded by California’s HVIP incentive program.
Electrek’s Take
Schneider is among the many global fleets that are proving the reliability and efficacy of battery-electric semi trucks every day, racking up millions of miles faster than many of the nay-sayers thought would be possible. The only real question facing the world of electric trucking now is whether the legacy brands like Freightliner and Volvo have established an insurmountable lead over Tesla.
