Googled it, and below is one of the comments i read. Not sure how true it is.
A comment on YouTube claims that, 'The music for the UK version of the BMW Z4 “An Expression of Joy” advert, according to the official statement from the BMW Marketing Department, is that the song is untitled and was written by the Marketing Department specifically for the advertisement. Unfortunately, there seems to be no plans to release it as a single'.
