The 42V system is really a 36V system (= 12V X 3). However, the nominal
regulated voltage in today's cars is 14V = (42/3).

Why on earth would they use 42 Volts instead of the 48 Volt systems
already in use in many other platforms? 42 volt systems will require
a new set of development as opposed to the COTS (commercial off the shelf)
solutions already available. Being 3.3 volts, the microprocessor controls
will require DC-DC converters in any case ...
