I'm not aware of any new cars that have only a single uP. Everything
since
the OBD and CAN systems has a microprocessor where it is needed, and a
bus
that runs through the car to the various microprocessors. Many new
cars have
a microprocessor for the engine, one for the transmission, one for the
air
bag systems, one for the brakes, one for climate control, one for the
stereo/CD/MP3 player, one for the navigation system, one for the
autodarkening
rear view mirror/compass, one for the dash board, one for the HVAC....

Your Datsun probably has one for the arm rests, and tail lights too ;-)

AFAIK my Mitsubishi Montero Sport has only one, for the engine control
unit. That's enough uC in a car for me.

So it doesn't have a clock, or a stereo?
