The Trumpf was conceived in 1934 as a smaller, more approachable model that was meant to move the company into a broader market and increase profits. Powered by a 995cc four-stroke side valve engine driving the front wheels, the Trumpf Junior was a direct competitor for DKW. The little Adler was available in a variety of body styles which ranged from a simple two-door “Limousine” (sedan/saloon) to a Cabrio Limousine to the wickedly stylish little Sports Roadster, as featured here. A streamlined Trumpf Junior set speed and endurance records at Avus in 1934, and this car and its success spawned the production Trumpf Junior Sport. Adlers also raced competitively at LeMans, the Alpine Rally, and the Spa 24 hrs, winning their class in 1935 and again in 1937. These Adlers were among the earliest scientifically streamlined racing cars and would be echoed in a few years by BMW and Alfa Romeo.
