[5] In the 1920s, Webasto focused on the production of bicycle parts such as fenders, gears, luggage racks, and handlebars.

In between, in 1935, the next product was developed: the heater for cars with water-cooled engines, called Auto-Frischluftheizung, operated by a heat exchanger.

Additionally, individual parts for military equipment, such as seat belt boxes or drums for machine guns, were produced.

[1] In the post-war period, the company produced everyday metal items from materials left over from the Wehrmacht.

Further subsidiary companies were established in Great Britain, France, Italy, the USA, Japan, China, and India.

In 1999, Franz Josef Kortüm became the CEO of Webasto, succeeding Prof. Rudi Noppen, who had led the company since 1992 as the first external manager.

Webasto has been a partner of the Startup Autobahn platform, the German branch of the US-based Plug and Play Tech Center, since 2017.

[24] Genetic sequencing also linked the cluster of cases at Webasto's headquarters to the virus outbreak in northern Italy.

[25] In May 2020 some medical disprove this assumptions and confirm that the Webasto case remained isolated,[26] while in July other studies identified the most common Italian strain as coming from Germany.

[27] In 2022, Webasto has joined forces with Bosch to develop a self-driving car that will enable autonomous driving at Level 4.
