Automotive sports are always attractive with their adrenaline and strong emotions. These are large-scale projects of companies that require specialized teams. Adapted to cars, tailored to a particular class of rally races and rally championships. Twice I have been invited to such projects. The specific invitation came from Volkswagen Hobby Car Ltd., Ruse – an authorized representative of Volkswagen cars. The company was developing car adaptation activities for local and international rally championships. We participated in the projects with ten people – specialists in certain areas, for the purpose of developing rally cars. For both projects, Volkswagen Polo, 2008, was used.
