1935 - Volvo takes over
Volvo business became more and more important for Penta and in 1935 Volvo bought its engine supplier and renamed the company Volvo Pentaverken. At the same time a design and sales department for non-automotive engines was set up in Goteborg under the name AB Pentaverken.
The same year the Hesselman engine was introduced: a six-cylinder crude-oil engine with three-cylinder idling, a very advanced design for its time. Women were employed in the company for the first time.
