The account is to support the car maker's internal comms team at its three UK manufacturing plants: in Hams Hall, which manufactures engines; in Swindon, which makes body pressings and sub-assemblies; and at its Mini production facility in Oxford.
Red Marlin won the account, which is new for BMW, after a competitive pitch.
BMW is Red Marlin's first vehicle manufacturer client. Its others include Yokohama tyres and - a more recent addition - motorsport racing team Iron Lynx.
Danny Rughoobeer, agency managing director and founder, said: “Our work with BMW Group is an exciting milestone for Red Marlin. The company employs thousands of people at its plants across the UK, and with the fast-paced and frequent changes that often occur within our industry, reaching the workforce with powerful messaging is a crucial element to the success of the business.”
The independent agency was founded in 2009 and is based at the heart of the UK’s car industry in Leamington Spa, Warwickshire.
