Back to the car voltage level. If the industry finally bit the bullet and went from 12V to 36V or 48V systems then it enables all kind of improvements. 48Volts is the maximum since anything larger would introduce safety hazards.
1) Sizes of all copper wires get smaller. (Saving Weight)
2) With smaller wires it makes it effecient now to move the battery to the rear of the car to help with weight distribution. (12V battery in the trunk means you have to add 5-10 lbs of wire back to the front.)
3) Sizes of all auxilary electrical motors decrease. (Windows, door locks, seats, vents, grill blocks, blower motors, etc)
3) All vehicles could then come with automatic start/stop and belt driven starter/generator. (It is hard to do start/stop with only 12Volts) Saturn VUE has 36V battery for it's belt driven mild hybrid as well as standard 12V.
4) Would allow mild hybrid (and mild brake energy capture) if you replace flywheel with Integrated starter/generator.
