Just to add the basic idea, the amount of power is amps * volts. So to carry the same amount of energy with a higher voltage, you can you use less amps. The amount of amps impacts how big the wires are, lower amps need smaller wires and that means less space for wires but more importantly less weight of the wires. There is a lot of wiring in a car. Tesla claims this could be 1/4 the amount of copper wiring in an article, below.

This article describes a bit about this, but also says something I never heard, that there were 6v auto systems in the 1960s. https://www.mining.com/new-tesla-low-voltage-system-a-big-de...

It may help some also to know what an amp actually is: 6.241x10^18 protons or electrons per 1 second of time passing a certain point. A single Amp is equal to 1 Coulomb and 1 Coulomb has 1 Joule of energy. I share this from my personal documentation in comprehension of understanding the unseen resulting from a device I am building to solve a personal energy storage problem. All open knowledge certainly but graphing these relationships into a visual depiction of the correlation has greatly assisted when talking to others that have ZERO knowledge about energy and power. Humans are nearly all 100% visual so explaining it with pictures presents A LOT of AHA moments for those without such comprehension.

The inverse relationship between amps and volts can also help: 50 volts * 24 Amps = 1200 Watts 100 Volts * 12 Amps = 1200 Watts 120 Volts * 10 Amps = 1200 Watts 150 Volts * 8 Amps = 1200 Watts 200 Volts * 6 Amps = 1200 Watts 240 Volts * 5 Amps = 1200 Watts 360 Volts * 3.333 Amps = 1200 Watts 480 Volts * 2.5 Amps = 1200 Watts 600 Volts * 2 Amps = 1200 Watts

6 volt autos were going out of style in the 1950s. They did last into the 1960s, but they were already rare by then.
