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 ;-)

Q45, GPS/Navigation, Sirius/FM/AM, CD, tape, seats (front and back),
HVAC controls (front and back), back-up camera, electric windows,
heated/cooled seats, 8 air bags, cruise control, adjustable suspension
and rear-end, sun roof, 0-60 mph acceleration time of 6.7 seconds, and
340 hp (253 kW) 4.5 L VK45DE V8 engine, and 333 lb-ft of torque
