The new vehicle voltage standard is 42V. This is already implemented on
some vehicles in Europe (significantly higher emphasis on diesel) and is
expected to be on some U.S. domestic vehicles as early as C/Y 2004. BMW is
expected to have 2004 M/Y vehicles in the U.S. with 42V. GM/F/DC were
targeting M/Y 2005, but haven't heard anything lately. All of this is
driven by more on-board vehicle electronics, requiring higher 12V current.

Not need for them to wake up. They already did!
I read (RSGB RadCom magazine) that the car manufacturers are
already thinking about implementing a higher DC voltage car system
standard in the near future.
One of the reasons is the economical one indeed.
Another one is the heavy load (audio, radio, video, GPS, computers,
plus the future other....) for the usual 12V system.
So, the 1.5 kW mobile may be closer that we think...
