In this research paper our aim is to explain the ambush marketing in the real world between the company rivals. It is the marketing activity done by a company to degrade the marketing of the other rival company. We have focused mainly on the two German automobile companies i.e. AUDI and BMW. We have discussed about the event of marketing between the two companies and also their comparative analysis in the fields of ambush marketing. We have also discussed the different strategies of both the companies and their current marketing state. We have done an in- depth research in the ambush marketing activities and how it affects the marketing activities of the other companies in the market. As it is also known as a negative marketing so it always disturbs the relations between the companies. It is also done in two ways direct and indirect which we have discussed further in this research paper.
