This occurred primarily because of the pioneering efforts of industrialist Franz Saurer, who move his foundry from St. Gallen to Arbon in 1863.
In 1911 the castle was bought by Adolph Saurer, the founder of Adolph Saurer AG.
In Poland the state-owned Państwowe Zakłady Inżynieryjne produced license-built Saurer engines (powering, among others, the 7TP and 9TP tanks) and coach chassis used in the Zawrat bus.
The buses, primarily manufactured by Saurer, Benz, and Daimler, were small and could accept six to ten passengers.
The bus was based on a license-built chassis of the Saurer 3CT1D bus designed by Swiss Saurer company and a six-cylinder Saurer BLD engine, also license-built in Poland.

The Maybach HL 295 (a redesigned German gas engine in 1945 captured at Friedrichshafen by Engineer-General Joseph Molinié) and a Saurer diesel engine were tested.
Following this success, Simca took over the French truck manufacturers Unic in 1951, and Saurer in 1956, the Poissy plant of Ford SAF in 1954.
