It's nominally 42 volts (13.8 x 3).
The auto companies have been talking aboiut this for several years now, but
the most recent estimate I saw was somewhere around 2010.
Part of the problem is that the automakers have so much capital tied up in
accounting rules for their fixtures and factories that there's a
disincentive to modernize.
We saw how pervasive this problem was when the US bailed out Chrysler. I
would not be surprised to see something like this happen again -- after
all, just yesterday the Senate handed Detroit a signiicant disincentive to
modernize cars wehn they axed the improved mileage requirement from an
energy package.
To the benefit of certain states with significant petroleum business interests.
