Josef Herbert Ernst Fiala (born 2 September 1928, in Vienna) is an Austrian automotive engineer.
Because of the attributed ability to explain complicated technical processes in an easily understandable way, he was ordered in part-time to the directorate of the Hamburg Transport Academy.
He had a share in the development of the catalytic converter, the lowering of the drag coefficient, making the diesel engine suitable for middle-class cars and the track-stabilized steering.
After completing the age of 60 Fiala gave up his job for dedicated more intensively scientific and journalistic work.
As a consultant, he stayed in touch with Volkswagen, and as honorary professor at the Vienna University of Technology he taught the subject "Interrelations between man and vehicle".
