Tesla has applied for a patent on a new “ultra-hard” steel alloy that it plans to use with the Cybertruck electric pickup truck.
One of the Cybertruck’s biggest differentiating features is the fact that Tesla plans to build it with a body and “exoskeleton” made of “ultra-hard” stainless steel:
Cybertruck is built with an exterior shell made for ultimate durability and passenger protection. Starting with a nearly impenetrable exoskeleton, every component is designed for superior strength and endurance, from Ultra-Hard 30X Cold-Rolled stainless-steel structural skin to Tesla armor glass.
The automaker said that it planned to develop its own alloy for it, and now it has applied for a patent to secure the intellectual property behind it.
In the patent application called “Ultra-Hard Cold-Worked Steel Alloy,” Tesla noted that it could be used in a vehicle with an exoskeleton:
In some embodiments, at least one exterior panel and/or body of the vehicle comprises the steel alloy. In some embodiments, the vehicle architecture is designed such that the exterior panels of the vehicle also contribute to the vehicle’s structural performance, wherein such exterior paneling of a vehicle may be referred to as an “exoskeleton.” In some embodiments, the exterior panel is or is formed from a monolithic metal sheet of the steel alloy. In some embodiments, the corrosion resistance of the monolithic metal sheet allows for the exterior panel of the vehicle to be utilized without application of an anticorrosion coating or corrosion protective agent (e.g. paint). In some embodiments, an exterior surface of the exterior panel does not comprise paint.
This leads us to believe it is indeed the alloy that Tesla plans to use for the Cybertruck.
In the patent application, Tesla shared some technical specs of the steel alloy:
In one aspect, a steel alloy composition is described. The composition includes Fe, a hardness is at least about 400 HV, and an Epit-Eocp corrosion resistance of at least about 500 mV in a 3 wt% sodium chloride aqueous solution.
In some embodiments, the hardness is about 420 HV to about 500 HV. In some embodiments, the Epit-Eocp corrosion resistance is about 520 mV to about 800 mV. In some embodiments, the Epit-Eocp corrosion resistance is about 520 mV to about 600 mV. In some embodiments, the composition has a yield strength of at least about 1100 MPa. In some embodiments, the composition has a ductility of at least about 60° bend angle at 1.8mm thickness. In some embodiments, martensite formation begins at about 260 K to about 340 K. In some embodiments, martensite formation begins at about 260 K to about 320 K. In some embodiments, the composition has at least about 12 vol% martensite. In some embodiments, the composition has a yield strength of at least about 1100 MPa.
The automaker claims that it outperforms other alloys:
It’s still not clear who is going to manufacture this alloy for Tesla, but there have been rumors that Steel Dynamics, which is operating a new giant plant in Texas not too far from where Tesla plans to manufacture the Cybertruck, could be a potential partner.
Tesla plans to start production of the Cybertruck at Gigafactory Texas in Austin this summer and ramp up to volume production next year.

Lectric’s April sale offers largest bundle ever on XPress 750 Commuter e-bikes at $1,399 (Up to $654 in FREE add-ons)
After the exciting April Fool’s Day flash sale, Lectric has switched gears to its longer-lasting April Showers Sale that is offering up to $654 in free gear along with e-bike purchases. Of course, the XP 3.0 e-bikes are prominently featured once again, this time with $500 bundles, and we’re seeing the other models retain the price cuts from previous sales, but I wanted to take the time to shine a spotlight on the XPress 750 Commuter e-bike for $1,399 shipped that is getting $557 in free gear. This bundle would normally run you $1,956 in all, with this being the largest package to accompany the e-bike that we have seen to date. Along with your purchase, you’ll be getting a rear cargo rack, a suspension seat post, fenders to go over both wheels, an Elite headlight, adjustable rear mirrors, an accordion-style folding bike lock, a wide saddle, a phone mount, and a 1.5L top tube bag.
Coming with the option for a high-step or step-through frame, the XPress 750 e-bike is a solid choice for commuters who are looking for significant travel support, with my own regularly getting me across Brooklyn, never once having me concerned about running out of battery. It’s been given a 750W rear hub motor (that peaks at 1,310W), a removable 48V 14Ah battery, and comes supported by five levels of PAS that themselves are supported by a torque sensor – all to provide you with up to 60 miles of travel at 20 MPH speeds, which can go to 28 MPH should you live in a state that allows it. Of course, for those wanting to ride on pure electricity, there is a throttle here, though keep in mind it will lessen your mileage.

Ford’s vehicles are about to get a whole lot cheaper. With its new “From America, For America” campaign, launched Thursday, Ford is rolling out steep discounts, including employee pricing for all, and a free home charger for EV buyers.
The new campaign promotes Ford’s “American-made” vehicles with some pretty sweet deals. Ford is offering employee pricing on most 2024 and 2025 model vehicles.
All Ford and Lincoln models except the F-150 Raptors, 2025 Super Duty pickups, and Expedition are included. The Lincoln Navigator and Ford’s fleet vehicles are also excluded.
Ford is also extending its “Power Promise” promo, which offers EV shoppers a free Level 2 home charger (plus standard installation), 24/7 live electric vehicle support, roadside assistance, and an 8-year, 100,000-battery warranty.

The program was initially launched in October, but Ford extended it through the end of March after seeing an uptick in EV sales.
Ford’s Power Promise now runs through June 30 and is available for any new EV purchase or lease, including the Mustang Mach-E and F-150 Lightning pickup.

According to Rob Kaffl, Ford’s director of US sales, the company is able to offer steep discounts because it has the inventory. Kaffl told The Detroit Free Press, “We’re in a very competitive position in our stock.”
With “a lot of uncertainty in the market right now” amid Trump’s new tariffs taking effect, Kaffl said Ford’s new “From America, For America” will provide some security.

How significant are the discounts? Well, it will depend on the vehicle’s cost. A Ford dealer (who asked to remain anonymous) said an F-150 XLT hybrid with an MSARP of $65,000 would cost $55,000 under the employee pricing plan. The price of an Escape ST SUV, with an MSRP of $36,300, would be cut to $33,000.
Ford introduced the 2025 F-150 Lightning last week, with a new “Dark Elements” package and improved charging features. It still starts at $62,995.
The 2025 Ford Mustang Mach-E starts at $36,495 and is available in RWD (260-mile range) or eAWD (240-mile range). Upgrading to the extended battery will cost an extra $5,500 (eAWD only).
Electrek’s Take
The new promo comes after Ford reported on Tuesday that US sales fell by 1.3% in the first quarter. Despite limited inventory, the Mustang Mach-E is off to a record start in 2025, with over 11,600 units sold, outpacing the Chevy Equinox EV and Honda Prologue.
GM reported US sales growth of nearly 17% in the first three months of 2025. After EV sales doubled to 31,887, GM remained the number two seller of EVs in the US behind Tesla, topping Ford’s 22,550.
Although Ford has the largest manufacturing footprint in the US of any legacy automaker, CEO Jim Farley says it’s still not immune to the tariffs.
Ford imports about 21% of the vehicles it sells in the US. GM imports around 46%. Both are looking to get ahead of any potential impacts.

Trump’s new tariffs on China have just kneecapped Tesla’s only growing business: energy storage, which uses battery cells from China.
Tesla released its delivery results for Q1 2025 yesterday, which were quite disastrous. At 336,000 electric vehicle deliveries, they were 40,000 units below the consensus and about 20,000 units below what even the most pessimistic analysts expected.
But there was one silver lining: Tesla reported having deployed 10 GWh of energy storage – a new record for a first quarter.
While Tesla’s electric vehicle business entered a downturn in 2024, which is now accelerating in 2025, Tesla’s energy business, which primarily consists of selling Megapacks and Powerwalls, has been consistently growing.

The bulk of this growth can be attributed to Tesla’s production ramp at its Lathrop Megafactory, where it produces the Megapack, and in the launch and production ramp of the Powerwall 3 with LFP battery cells.
Tesla now uses LFP battery cells from China to build these energy storage systems in California and Nevada.
This will significantly increase the prices of Tesla’s Powerwall and Megapack products, which should reduce the market.
The Biden administration had already announced an increase to 25% tariffs on Chinese battery cells meant for energy storage, coming in 2026.
Tesla was already bracing for the new tariff, but the Trump administration has dramatically accelerated the timeline and increased the tariffs. The administration has confirmed that the tariffs are stacking up on top of each other, which would mean 54% for goods coming from China.
The company is believed to almost exclusively use LFP battery cells from China’s CATL in its stationary energy storage products.
Tesla has also recently started production at a new Megafactory in Shanghai to produce the Megapack. The battery systems coming out of that plant are expected to be shipped to markets outside of the US and should enable Tesla to stay competitive outside the US.
Although, as we previously reported, Tesla is starting to face intense competition from its own battery suppliers for these products, CATL and BYD, which have both recently unveiled products to compete with the Megapack.
Tesla has also recently announced plans to build a second Megafactory in the US to build more Megapacks, but it’s not clear how those plans are going to be affected by the new tariffs.
Electrek’s Take
Since last year, stationary energy storage has been Tesla’s only growing business unit, and I was already worried about it because of increased competition. BYD and CATL already have a hold on LFP cells going into the Megapack, and now they are making their own Megapack products with their own cells.
Now, Tesla has to worry about tariffs significantly increasing the price of its Megapacks and Powerwalls in its biggest market: the US.
There’s a chance that Tesla has accumulated some inventory in anticipation of the tariffs, but unless they are removed, which is not impossible considering how volatile the administration has been about implementing its promised tariffs, it will result in massive Megapack and Powerwall price increases.
