In the 1920s, Kamm worked for Daimler designing engineering race car engines. Thereafter, a prototype, namely the Kamm “SHW Wagen” incorporated principles that have become standard parts of the car engineering toolbox. He paid particular attention to the suspension and minimizing vehicle weight. These improvements included extreme low weight design, an aluminum semi-monocoque body, front wheel drive, boxer-style engines (horizontally opposed cylinders), independent suspension on all wheels, and coil springs mated to hydraulic shock absorbers. His comprehensive approach to automotive engineering and design presaged the concept of "Mechatronics," a word that did not come into existence until 1971.
