Even when presented, Tesla’s amazing Cybertruck continues to talk to people. On this occasion, history comes to approve a message that he launched. Elon Musk by making sure they send all the manufacturers a letter talking about the design and standardization of the 48-volt electrical system used in their new electric pick-up. It sounds arrogant, but Ford confirmed the receipt of said letter and, indeed, they got it right.
The revelation emerged through a brief but significant exchange of messages on X (formerly Twitter) between Jim Farley CEO of Ford, and Elon Musk, the CEO of Tesla.

Farley’s message refers to a document sent by Tesla to the CEOs of the world’s leading car manufacturers explaining “how to design a car with a 48-volt electrical system”.
In this document they explain how Tesla has successfully integrated a 48-volt electrical system into its electric pick-up, the more expensive Cybertruck. Instead of the traditional 12-volt system for the entire low-voltage electrical system (not to be confused with the engine’s electrical system), the Cybertruck uses a 48-volt architecture for power windows, lights, or infotainment systems.
Although it can be understood as a gesture of some arrogance, Musk’s company sent the document with its best intentions and with the intention that more manufacturers use this technology widely.
Farley not only confirmed that he received the said document, but also assured that Ford is developing “something similar” for the next generation of electric vehicles. The American manager immediately extended his hand to “work together” and also adopt 48-volt technology for the auxiliary electrical system of your vehicles.
Although the industry has been rooted in 12-volt systems since the 1960s, Tesla’s initiative to openly share its developments with other manufacturers shows openness to adopting new technology. However, while Ford is receptive, the path to implementing 48-volt systems will require widespread support.
The appeal of a 48-volt system lies in its ability to optimize costs for manufacturers, reducing the number of cables required for the power of car accessories. Fewer cables mean less car weight, less cost, and a little faster to build the car.
Currently, Ford vehicles, both electric, hybrid, and thermal, have a traditional 12-volt system for all their auxiliary electrical equipment. The question that now remains up in the air is when, if ever, the leap to 48-volt technology will be made, as Jim Farley explains.
