Count Alexander Kolowrat known as Sascha had the idea for this vehicle. Kolowrat was also an Austro Daimler shareholder. He posed Porsche the question as to whether he had to construct such large, heavy cars because the Americans would build much lighter cars. After the Austro Daimler Board of Directors refused to finance a compact car project, Sascha Kolowrat financed the venture himself. Porsche and his design engineer Otto Köhler his engineer Karl Rabe and Otto Zadnik who was responsible for the electrics designed and developed the Sascha car. In recognition of the sponsor, they named the car the ADS-R, with the S standing for Sascha.
Kolowrat and Porsche, both enthusiastic racers, constructed a racing version of the Sascha in which they set the engine deeper and further towards the rear. This meant better weight distribution and a deeper centre of gravity. The first time it was raced in the 1922 Targa Florio in the mountains in the south of Cerda in Sicily, Sascha Kolowrat’s car was withdrawn with engine failure. Three of the four Sascha’s that started the race came in top of their class.
