It requires smaller wire to deliver the same power to devices. Smaller wire is both cheaper and reduces the weight of the car, saving fuel (or charge if an electric car)

I don't see any clear advantages of switching to 48V.
Taking into consideration that today we have a huge amount of DC appliances it would be convenient to have the voltage fitting to them. Looking around it seems that 5V for USB sockets would be the optimal.
However, it's only for consumer electronics. More powerful devices, like vacuum, may not work well. And car's electronics and electric devices may require different voltages.
