A close-up of the rear trunk/bonnet of the weird-as-hell Citroën 2CV 4x4/Sahara, produced from 1960 to 1966.
As far as I know, the only serial-produced car with two engines, one at the front, the other at the back ! Produced at the Panhard factory in Paris, it gave you a great opportunity to drive a RWD 2CV, or being deaf with the two flat-twin running together.
