1973 Flug W15With the new company firmly on it's feet, it was time to expand the operation, and there was no better time to do so, as the fuel crisis hit. A demand for an economical cheap car was high as ever, and Flug was already well known for their value for money, so a new chassis was in order, as well as new engine. But having a sober look at previous adventures with Kraft Haus Technik, the CEO Viktor Kruger, now working on Flug exclusively, having left KHT, figured that only one of those was to come.
Once again the old and cheap Galt communitasia was summoned to donor the chassis, starting with the ladder frame and ending with the coil spring solid rear axle, but that's where the similarities ended. Having set aside enough funds, a new sub-facility was now operational, capable of producing complete engines. The facility was given the task to mass produce the newly designed FL4-15C-73 engines. The 4 cylinder pushrod 1.5 liter engine made of cast iron used a twin single barrel eco carburetor setup, and reached the redline of 4500 rpm, while reaching 46hp and 109nm of torque.
A 4 speed manual transmission delivered the power to the fist time ever for Flug the front wheels. Front brakes used were a 1 piston solid disc units, while using drum brakes in the back. A lot of thought went into safety. For the whole life cycle of the w15, this was considered an advanced car for the 70's in terms of it's safety. The interior, however had little to give to returning Flug customers.
The car seated 4 in a basic interior that did not include even a radio or power steering. This was not only making the car cheaper, it also was a cost cut on behalf of Flug automotive, to compensate for the design of a whole new engine and drivetrain.
The resulting W15 series was a hit, and scored highly in terms in reliability, practicality, drivability and economy. With the combined economy of 7.4 liter / 100km and a price tag of $8500 it was an instant hit with numerous markets which needed a budget solution for the whole family.
