Audi's lack of notice over DTM exit "unsporting" - BMW
BMW board member Klaus Frohlich, "It's not for me to evaluate another company. But from my point of view Audi is undergoing a far-reaching restructuring process.
"Whether it was sustainable to cut off the DTM pillar and whether Formula E is more viable in the long-term to communicate electric mobility - I put a question mark over that."
So Audi quitting from DTM is not really a marketing decision according to BMW. Also BMW reveals that DTM would become full electric in 2025.
