Himmer will move to Ireland from Germany, where he is currently based in his role as Head of Group Sales Strategy.
His previous automotive experience includes CEO roles for Eastern Europe and for Russia/CIS with MAN Truck & Bus. Prior to joining the Volkswagen Group he was Managing Director with Volvo Trucks in the Balkans and Latvia; prior to that he was Deputy MD of Volvo Trucks in Russia.
Himmer is from Denmark and spent his early career as an officer in the Danish Army before joining the diplomatic service. He subsequently worked for Dandy in both operational and HR roles before making the transition to the automotive industry.
He studied in Denmark, England and Switzerland for an MBA and an International Business Degree.
"I am delighted to be coming to Ireland at an exciting time for the Irish car market," Himmer said on his appointment.
"It is evident that there has been a lot of hard work done up until now through a challenging period, but I hope, together with the brand teams, we can enhance Volkswagen's market position even further and continue strong growth in 2015 and beyond. I am also particularly looking forward to settling in Ireland in the New Year."
