That rumor has been around for 20 years. The advantage of higher voltage is you need less current for the same power. Less current means smaller wire size = less weight and cheaper. I doubt it will happen except maybe for electric vehicles or hybrids.

This is not just a rumor. I have a friend that is in the car deisgn industry. They are planning on this in the future. He says it will be 6-8 years in the future. But all automobiles will not change at the same time. And they will not be completly 42v right off the bat. They are planning hybrid versions of the 42v system to start off with. Then later on down the road go completly 42v.
