The Stahlradwagen (or "steel-wheeled car")[5] was Gottlieb Daimler's second motor car.[1]
After seeing Panhard's Daimler-designed V-twin engine demonstrated at the Paris Exposition of 1889 and inquiring into the engine's weight and power, Armand Peugeot expressed his interest in a lightweight motor vehicle powered by the engine. Daimler worked with Wilhelm Maybach to develop the vehicle.[6] The tubular steel frame resembled two bicycles joined side by side and was made by bicycle manufacturer Neckarsulmer Stahlfabriken, which would later become part of NSU Motorenwerke.[1][6] Water, to cool the engine, was run through the tubular frame.[7]
The Stahlradwagen was demonstrated toward the end of the 1889 Exposition.[4][8] Peugeot began building cars based on the Stahlradwagen design by 1890.[3][7]
Displayed at the 1889 World's Fair in Paris, their creation was called the Stahlradwagen (steel-wheeled car).
