Rasmussen specified an innovative design, with good road-holding qualities, thus he required a chassis with the lowest possible centre of gravity, featuring front-wheel drive, and independent suspension.

[1] After just six weeks the team designed a 2 + 1 seater roadster with a curb weight of 450 kg including a full fuel tank of 25 litres, and which offered exceptional[unbalanced opinion?]

[1] This would be the car which appeared at the Berlin Motor Show in February 1931 with an open topped steel body, and a 494 cc two-cylinder two-stroke engine.

By the time, later in the same year, that cars were in production for sale, the design had been altered with a stronger drive shaft mechanism, and a simpler, cheaper timber frame body, clad in imitation leather.

Nevertheless, sales brochures dating from the summer of 1932 still included both engine sizes, which enabled the manufacturer to advertise an "eye catchingly low"[tone] starting price for the car.

The F1, like subsequent front wheel drive DKWs "till"[tone] 1942, was assembled at the company's Zwickau plant which Rasmussen had acquired for the business in 1928[4] or 1929 by becoming a majority shareholder in Audi-Werke AG.
