Tesla shares 48V architecture with other automakers to move the industry
One of the less obvious features of the Tesla Cybertruck is its vehicle voltage architecture. The Cybertruck is the first EV from the automaker to use a 48-Volt (48V) electrical system implementation throughout the entire vehicle, as compared to the 12V systems that are used in pretty much every other vehicle on the planet. Today, Tesla shared its 48V implementation documentation with other major automakers — including competitors like Ford.
Ford’s own CEO Jim Farley confirmed the news on X, formerly Twitter, last night.
Tesla CEO Elon Musk also chimed in.
The consequences of Tesla’s actions won’t be immediately obvious in any other carmaker’s products, as they will likely take a long time to manifest into any real changes for the industry — if they do at all. But let’s take a step back.
Why does 48V architecture matter?
48V architecture is a huge deal not because it enables any particular feature or capability for any one car, but because it will lead to a step change in how automakers wire, accessorize, and electrically engineer their vehicles.
The first mass-produced vehicles generally used 6V architecture to power things like headlamps, and the industry broadly began to adopt 12V electrics in the 1950s. By the late 1960s, almost every car on sale in the US used 12V electrics — power windows, interior lighting, cigarette lighters, brake lights, ignition spark, batteries, and more all unified around this common voltage standard. This change was a big deal, because it meant that the suppliers who built a lot of these electrically-driven components could easily adapt their products to work with any car. Parts became yet more standardized (plus, more affordable and reliable), and eventually 12V became the universal standard for vehicle electrics.
The problems with 12V architecture, though, have been looming (pun intended) for years. Because of the low voltage of this architecture, delivering sufficient power to all vehicle systems that need electricity became more and more complex. And as cars integrated more and more electrical components over the years, this led to ruinously complicated vehicle wiring layouts. (I want to be clear: I am vastly oversimplifying the nature of the challenges of 12V architecture, and it should be obvious by now I’m not an electrical engineer. I probably shouldn’t be allowed to be too close to a wall outlet, frankly.)
Switching to 48V architecture alleviates a huge number of challenges automakers are facing with 12V. The biggest one, though, is complexity: You need far less complex wiring harnesses to power all your vehicle systems, because each wire can supply far more power and voltage in a 48V system. 48V architecture also potentially improves overall electrical efficiency for reasons that I am not sufficiently qualified to explain beyond a kindergarten level, meaning your car’s accessory systems may require less power overall to operate (quite important for an EV).
12V roadblocks remain despite Tesla’s action
The challenge in adopting 48V architecture primarily lays in the vehicle supplier ecosystem, but that conclusion requires a bit of context setting.
If you cannot convert all of a vehicle’s systems to 48V architecture, the benefits of using such an architecture start to diminish pretty quickly in the form of introducing new complexities (i.e., a hybrid 48V / 12V vehicle architecture). As such, most automakers have clung to 12V because they know it and it works.
If an automaker decides to move to a 48V architecture, whatever car it builds must use 48V-ready accessories. But, suppliers aren’t incentivized to build such accessories without sufficient demand. While carmakers like Ford certainly have the power and scale to commission 48V parts independently, the per-unit cost of those components is likely to be substantially higher than their 12V equivalents — especially if they’re being produced in comparatively low volumes. And, many carmakers would be forced to make such a transition slowly over their entire vehicle lineup (it’s worth noting that ICE vehicles can use and would benefit greatly from 48V systems, too). And so, most carmakers stick with 12V. It’s a chicken-and-egg kind of issue.
Why did Tesla share its 48V architecture?
To be frank, Tesla isn’t sharing its 48V architecture from the Cybertruck for purely altruistic reasons. Once you understand the conundrum around vehicle suppliers in the 12V world and making a transition to 48V, things start to come into greater focus. Tesla knows that transitioning to 48V is going to be incredibly difficult for legacy OEMs, and while there is potentially upside for Tesla in such a change (more on that in a moment), this is something of a PR move.
By publishing its 48V architecture, Tesla is saying “OK, we’ll show you how we did this thing — a thing you say is really complicated and difficult and would take years to replicate. You can just copy us.” But Tesla knows full well that even a powerful and well-resourced company like Ford can’t spin up a 48V accessory supply chain overnight, and that such a change would incur very substantial non-recurring engineering work (NRE, as it’s known in some industries).
For Tesla, though, there are theoretical benefits in the event the wider industry switches to 48V vehicle systems. The biggest one is the supply chain. The more components in the global vehicle supply chain that are designed for 48V vehicle systems, the lower the cost of those components will become over time — through volume, competitive engineering, and increased reliability. The second is a bit more nebulous, but arguably just as important: Engineers and other skilled workers in the industry will coalesce their work and knowledge around 48V systems, reducing the amount of redundant work happening and increasing the number of workers in the hiring pool who can understand and innovate on Tesla’s systems (and who can bring their knowledge to Tesla, barring any intellectual property infringement, of course).
Electrek’s Take
It’s hard to see a downside to this move for anyone — for Tesla, the industry, or for the engineers designing the vehicle systems themselves. And it’s plain that the supplier ecosystem needs a kick in the pants to accelerate the transition to 48V, and that the benefits of such a transition are very substantial.
But it’s much harder to say how much of an impact Tesla’s decision to share its 48V design will actually have. Clearly, automakers are already incentivized to move to 48V, but doing so is challenging for a reason — it’s not just laziness. There are legitimate (if frustratingly financial and logistical) reasons that the 48V transition is moving along slowly.
It’s very possible that providing publicity around this relatively esoteric technical issue will be the greatest factor in instigating more aggressive work to implement 48V vehicle systems, as opposed to any technical know-how gleaned from Tesla’s documentation.
It should also be noted that Tesla has two distinct advantages in transitioning to 48V that legacy automakers do not. The first is being unusually vertically integrated in its approach to building vehicles — Tesla designs almost all of its own vehicle systems, even if they may be procured from third parties who actually manufacture them. The second is that Tesla doesn’t have many legacy vehicle designs to support or consider in deciding to transition electrical architectures. Put another way, Tesla’s focus on independent engineering and low legacy debt are huge reasons it can introduce a 48V vehicle while other auto OEMs continue to stick to 12V and likely will for years from now, even in their EVs. And simply telling other carmakers how it built a 48V system won’t change those realities overnight.

Believe it or not, you can lease an EV for under $200 a month. New deals on models like the 2025 Hyundai IONIQ 5 and Kia EV6 are hard to pass up this month.
Electric vehicles have been all over the news lately, with the Trump administration threatening to end federal incentives and introducing new tariffs that are expected to lead to higher prices.
On the positive side, new EV models are arriving, giving buyers more options and driving prices down. Many automakers reported record US electric car sales in the first three months of 2024.
GM remained the number two seller of EVs behind Tesla after sales doubled in Q1 2025. With the new Equinox, Blazer, and Silverado EVs rolling out, Chevy is now the fastest-growing EV brand in the US. Ford’s Mustang Mach-E is off to its best sales start since launching, with over 11,600 models sold in the first quarter.
With the 2025 models rolling out and about 15 new EVs arriving this year, many automakers are introducing steep discounts to move vehicles off the lot.
EVs for lease for under $200 a month in April
Although the decade-old Nissan LEAF remains one of the most affordable this April at just $149 per month, there are a few EVs under $200 right now that are worth taking a look at.
The new 2025 Hyundai IONIQ might be the best EV deal this month, with leases as low as $199. Hyundai is currently promoting a 24-month lease deal with $3,999 due at signing.
Hyundai upgraded the electric SUV with a bigger battery for more range (now up to 318 miles), a sleek new look inside and out, and it now comes with an NACS port so you can charge it at Tesla Superchargers.
The offer is for the IONIQ 5 SE RWD Standard Range, which has a driving range of up to 245 miles. For just $229 a month, you can snag the SE RWD model, which has a range of up to 318 miles and a more powerful (225 horsepower) electric motor. It’s also a 24-month lease with $3,999 due at signing.
To sweeten the deal, Hyundai is offering a free ChargePoint Home Flex Level 2 EV charger with the purchase or lease of any 2024 or 2025 IONIQ 5. If you already have one, you can opt for a $400 public charging credit.
After slashing lease prices this month, the 2025 Nissan Ariya is actually cheaper than the LEAF in some regions. In Southern California, the 2025 Nissan Ariya Evolve AWD is listed at just $129 per month. The AWD model has a range of up to 272 miles.
The deal is for 36 months, with $4,409 due at signing. In April, Nissan cut Ariya lease prices to around $239 in most other parts of the country.
Kia has a few EVs available to lease for under $200 a month in April. The 2025 Kia Niro EV Wind is listed at just $129 for 24 months, with $3,999 due at signing. Kia’s crossover SUV has EPA-estimated range of 253 miles.
The 2024 EV6 may be worth considering at just $179 for 24 months ($3,999 due at signing). In California, the EV6 Light Long Range RWD is only slightly more than the Niro Wind.
In most other parts of the country, you can still find the EV6 for under $200 a month. The Light Long Range RWD trim offers up to 310 miles of EPA-estimated range.

![The US’s first solar panels over canals pilot is now online [video]](https://i0.wp.com/electrek.co/wp-content/uploads/sites/3/2025/04/Project-Nexus-solar-canal.jpg?resize=1200,628&quality=82&strip=all&ssl=1)
Project Nexus, the first solar panel canopies over irrigation canals in the US, is now online in California, and there are plans to expand the project to other areas.
Project Nexus is a $20 million pilot in central California’s Turlock Irrigation District launched in October 2022. The project team is exploring solar over canal design, deployment, and co-benefits using canal infrastructure and the electrical grid.
India already has solar panels over canals, but Project Nexus is the first of its kind in the US.
The Turlock Irrigation District was the first irrigation district formed in California in 1887. It provides irrigation water to 4,700 growers who farm around 150,000 acres in the San Joaquin Valley.
Project Nexus will explore whether the solar panels reduce water evaporation as a result of midday shade and wind mitigation, create improvements to water quality through reduced vegetative growth, reduce canal maintenance as a result of reduced vegetative growth, and, of course, generate renewable electricity.
The California Department of Water Resources, utility company Turlock Irrigation District, Marin County, California-based water and energy project developer Solar AquaGrid, and The University of California, Merced, are partnering on the pilot. Project Nexus originated from a 2021 research project led by UC Merced alumna and project scientist Brandi McKuin.
Solar panels were installed at two sites over both wide- and narrow-span sections of Turlock Irrigation District canals in Stanislaus County, in various orientations. The sections range from 20 feet wide to 100 feet wide. University of California, Merced has positioned research equipment at both sites to collect baseline data so the researchers can decide where solar will work and where it won’t.
In February 2023, Project Nexus announced it would also deploy long-term iron flow battery storage in the form of two ESS 75kW turnkey “Energy Warehouse” batteries.
