Nice link, Flossy! I follow up with the very first production SAAB car: the SAAB 92A. It was built between 1950 and 1952. This car differs from Jays quite a bit even if they look similar. First, the drive train is transversal and with a 2 cylinder 2-stroke DKW engine. No water pump, circulation was done by Siphone effect. The was no trunk/boot to open - the space was only reached from inside car. Tank fill cap place, as you can see, was "racing"> Indicators where in the B-pillar with an interesting flip-out motion (can be seen in the later part of the video).
The free-wheel was a needed to keep the motor from sizing in long down hills with the foot off the pedal. If there is no throttle giving gas/oil during hight revs, the engine will size. It was not a way to save gas.:laugh:
