The contract represents a new client win for the agency, which made the final shortlist of three following an original proposal that involved five agencies in total.
The incentive programmes, which will include pre-event communications to engage participants and drive performance, will culminate in separate trips to Moscow and New York.
A group of 24 aftersales managers will be treated to three nights in Moscow, while 11 service advisors will be rewarded with a two-night trip to New York.
BMW event manager Rachael Carless said: "We were very impressed with DBMT’s creative execution and its passion and enthusiasm for the project."
DBMT account director Chetan Shah added: "This is a great win for us as an agency and we are very proud to be working with such a prestigious brand. We demonstrated a well-thought-out and creative solution that stretched the original brief."
