Stewart Easterbrook, Starcom UK group managing director, called the appointment "a validation of what Starcom can offer from a planning perspective".
He said: "The appointment represents an extension of our role with Honda and as a team we are very excited about the opportunity."
Ian Armstrong, manager of customer communications at Honda, said: "As media becomes more and more fragmented and distributed via an ever increasing number of spaces, it makes sense for us to apply a greater level of planning rigour than we have to date. Starcom is well placed to do that given our current relationship with it."
