The Adler Company of Frankfurt, Germany, hired Hans Gustav Röhr as its technical manager, and under his leadership, the Trumpf and the Trumpf Junior were created. The Adler Trumpf Junior is now regarded as one of the best-engineered cars of the 1930s.
The 1936 Adler Trumpf featured several modern and advanced elements that set it apart from other vehicles of its time. It came with a front-wheel-drive system, licensed from Tracta, which improved traction and handling, making the car more stable and easier to drive. This system was paired with a four-speed transaxle, enhancing the vehicle's efficiency and performance.
The car’s unibody construction, developed by Ambi-Budd, a subsidiary of the Budd Corporation, increased the structural strength while reducing weight, leading to better safety and performance. The inclusion of rack and pinion steering provided precise and responsive control, a notable advancement for the period.
The Adler Trumpf also boasted a four-wheel independent suspension system, with torsion bars supporting the rear wheels. This setup offered a smoother ride and better handling compared to the rigid axle suspensions that were commonly used at the time.
With around 50,000 units produced between 1933 and 1939, the Adler Trumpf was a commercial success. It remains a significant model in automotive history due to its combination of front-wheel drive, unibody construction, and independent suspension, all of which were advanced features during the 1930s.
The 1936 Adler Trumpf is still appreciated today for its innovative approach and solid engineering, reflecting the practical advancements of its era.
