PZInż 403 Lux-Sport

In 1934 the Państwowe Zakłady Inżynieryjne started work on a Polish luxury car for government officials that would replace foreign automobiles. The project was led by Kazimierz Studzinski, and in five months the car was designed and a chassis was complete. The car was of a simple, yet modern construction designed by Alexsander Rummel and Mieczysław Dębicki based on a central frame of two C-profiled beams. The car was called the Lux-Sport (or L-S) and had a completely independent suspension and used very long torsion bars as springing elements. The number of produced prototypes is not known, but at least one complete prototype, and one chassis for exhibitions were built. The PZInż 403 could have entered production in the 1940s, but the plans were abruptly stopped by the outbreak of World War II.

Though the prototype did not survive the war, the chassis was found after the war on a scrapyard. Today it is in the Museum Techniki in Warsaw.
