Stuck's racing experience began in 1922. He won his first hillclimb at Baden-Baden in 1923 and became a works driver for Austro-Daimler in 1927, excelling in hillclimbs and making his first circuit race appearance at the German Grand Prix that year. When Austro-Daimler withdrew from racing in 1931, he transitioned to sports car racing in a Mercedes-Benz SSKL.
In 1933, through his acquaintance with Adolf Hitler — whom he had met on a hunting trip in 1925 — Stuck was connected with Ferdinand Porsche and the new Auto Union project within Hitler's German motorsport promotion plans. Drawing on his extensive mountain pass racing experience, Stuck proved nearly unbeatable with the new Auto Union cars designed by Porsche. The rear-mounted engine offered superior traction compared to front-engine designs, allowing the machine's 500-plus horsepower to be utilised effectively even on unpaved roads.
In 1934 Stuck won the German, Swiss, and Czechoslovakian Grand Prix races, finishing second in the Italian Grand Prix and Eifelrennen, and claimed the European Mountain Championship — the first of three such titles. In 1935 he won the Italian Grand Prix and secured his second European Mountain Championship. The year 1936 proved leaner, with second-place finishes in the Tripoli and German Grands Prix; the European Mountain Championship that year went to his Auto Union teammate Bernd Rosemeyer while Stuck recovered from accident injuries. In 1937 he managed second-place finishes at the Rio de Janeiro and Belgian Grand Prix events.
In 1938, Stuck either left or was dismissed from the Auto Union team — accounts differ. Following injuries to other team drivers and government pressure, he was rehired and claimed his third European Mountain Championship, his final major pre-war achievement.
Although Germans faced a racing ban until 1950, Stuck obtained Austrian citizenship and immediately resumed racing. A connection with Alex von Falkenhausen led him to drive in Formula Two racing. He piloted a Porsche Spyder in 1953 and a BMW in Formula One between 1951 and 1953, starting three races for BRM, AFM, and Ferrari as a privateer without scoring championship points.
A BMW partnership beginning in 1957 proved more productive. His early hillclimbs for BMW in a Type 507 were unremarkable; notably, that particular chassis (70079) was later acquired by then-US Army Private Elvis Presley, disappearing until BMW Classic discovered and restored it in 2014 — it is now considered the most valuable in BMW's history, estimated at $17.9 million. Stuck's transition to BMW's compact 700 RS model proved successful: at age 60 he became German Hillclimb Champion one final time, retiring at that high point.
As a Nürburgring instructor in his later years, Stuck taught his son Hans-Joachim the secrets of the circuit.
Born in Warsaw to Swiss-ancestry parents who had relocated to Germany, Stuck served in World War I from 1917, losing his older brother Walter in 1918. He married three times: Ellen Hahndorff (1922), Paula von Reznicek (1932) — a celebrated tennis player whose Jewish grandfather created complications during the Nazi period, mitigated by Stuck's personal relationship with Hitler — and Christa Thielmann (1948), who survived until 2014 at age 93. His son Hans-Joachim was born in 1951.
