Volkswagen Group of America has announced the departure of Michael Horn, the company’s president and CEO. Through mutual agreement with Volkswagen AG, Horn will be leaving to pursue other opportunities effective immediately.

Hinrich J. Woebcken, who was recently announced as the new head of the North American region and chairman of Volkswagen Group of America, will assume the role of interim president and CEO.

“I want personally to say ‘thank you’ to Michael Horn for the great work he has done for the brand and with the dealers in the United States,” said Herbert Diess, CEO of the VW brand. “During his time in the US, Michael Horn built up a strong relationship with our national dealer body and showed exemplary leadership during difficult times for the brand,” he added.

Horn, 54, assumed the role as president and CEO in January 2014 and has over 25 years of experience with the VW Group. Before this, he served as VW’s global head of after sales. Horn joined the German carmaker in 1990 and has held many roles of increasing responsibility over his tenure, including head of VW sales North West Europe, head of sales and marketing luxury class vehicles, and head of sales for Europe.

He will be remembered for being in the eye of the VW Dieselgate storm, which blew up last September. “We’ve totally screwed up,” he admitted at the launch of the 2016 Volkswagen Passat after the emissions cheating scandal came to a head.
