I heard a few years back something about new cars being 48V in the near
future. Did it ever happen?

I just googled it. It didn't happen.

There was a plan in the 1980s to change cars to (I think) 32v. The idea
was to reduce the weight and cost of copper needed in a car by a factor
of about three. If the voltage was made any higher then
double-insulation and other safety measures would be needed, increasing
the cost. In the event the copper price reduced and the idea was shelved.
