Ford says it has now cast more than 5,000 giant aluminum pieces for the Fathom, its upcoming midsize electric pickup. The Ford Fathom unicastings are the clearest sign yet that Ford is copying the manufacturing trick Tesla started with its Giga Press, and the details Ford shared on Oct. 28 are more interesting than the headline number.
What’s confirmed
The update comes from Vladimir Bogachuk on Ford’s own From the Road blog. According to Ford, it has produced more than 5,000 large aluminum unicastings at its Shelbyville Technical Center. They are being used for process testing and prototype assembly at Louisville Assembly Plant, ahead of the Fathom’s 2027 launch.
Each Fathom gets a pair of unicastings, one for the front structure and one for the rear. Ford says that replaces 146 structural parts with just two, which cuts weight and improves overall energy efficiency.
The castings also change how Ford builds the truck. Under its new Universal Production System, the assembly line is split into three branches that build sections in parallel before they come together at the end. Ford says it is also working to shorten the casting cycle time and has engineered the parts for “modular repairability.”
As for the process, Ford describes melting aluminum ingots at about 1,300°F, injecting the metal into a front or rear mold, and then quenching, trimming and machining each part. Every batch goes through checks before it ships to Louisville, including industrial X-ray scans for pores and voids, dimensional measurements in a climate-controlled room, optical surface scans and tensile testing in a materials lab.
What’s rumored or reported
The price is where you need to be careful. Electrek’s coverage calls the Fathom a $28,350 midsize electric pickup. We are relaying that figure from Electrek, not from Ford’s casting post, and final pricing is something to check against Ford’s own site as launch gets closer. Our earlier look at Fathom dealer markup fears shows why the sticker price may not be the whole story.
Electrek also makes the Tesla comparison, and it is worth reading closely. Tesla introduced the Giga Press at Fremont in 2020, casting the Model Y’s rear underbody in one piece in place of 70 parts. Ford’s 146-to-2 figure sounds bigger, but the layout is front and rear, which is basically what Tesla launched with. Electrek’s read is that Ford is catching up rather than leapfrogging.
Electrek also reports that Tesla once planned to cast nearly the whole underbody in one piece, but Reuters reported in 2024 that it backed away from that, and Tesla has reportedly since dropped the front casting on some Model Y production. That is secondhand, and we have not seen Tesla confirm it.
The repair question nobody has answered
The big knock on huge castings is repair cost. A damaged one-piece structure can turn a moderate crash into a total loss. Electrek notes that a Lucid executive, Cory Steuben, has said insurance concerns were behind Lucid skipping gigacasting altogether.
Ford’s “modular repairability” line is its answer, but the company has not said what that means in practice. We don’t know yet whether a collision shop can replace part of a casting, what insurers will charge to cover a Fathom, or how repair bills will compare with a conventional stamped-steel truck. Those are the numbers shoppers will care about, and none have been published.
Why it matters for buyers
Fewer parts usually means a simpler line and, in theory, lower build costs, which is exactly what a sub-$30,000 electric truck needs. But as Electrek points out, a big press alone does not make a vehicle cheap; the whole factory has to work. Louisville is the test, and Ford is clearly rehearsing hard before launch.
For now, the takeaway is simple: the Fathom’s build process is real and moving, the final price and repair costs are not locked in, and the Tesla comparison is fair but not flattering. We will update this story as Ford shares more. For the wider picture, see our Ford trucks news hub.
