Hupmobile Model 32 History

Introduced alongside the final Model 20 in 1912, the Model 32 stepped up to a 106-inch wheelbase and a 32-horsepower four-cylinder engine backed by a three-speed manual. A longer 126-inch wheelbase variant was also offered, giving buyers a genuinely roomy five-passenger car at a modest price.

The model's landmark achievement was the all-steel body, developed by chief engineer Emil Nelson in collaboration with body designer Edward Budd and Joseph Ledwinka at the Hale & Kilburn stamping works. In 1911–1912, Hupmobile and British BSA shared the distinction of being the first automakers in the world to produce all-steel car bodies at scale. Steel stampings were welded together by hand, shipped by rail to Detroit, then painted and trimmed at the Hupmobile factory. Several thousand all-steel touring cars, coupes, and at least one limousine were built before Nelson resigned in 1912 and the remainder of Model 32 production reverted to conventional wood-framed construction.

The innovation established Hupmobile's reputation as a technology leader, not merely a budget builder. Commercial results were strong — 11,649 Model 32s were sold in 1913 alone — before the line was retired when the 1916 model-year lineup was announced.
