He will be replaced by VW's head of American aftermarket sales Michael Horn. Advertisement It was Browning, who has been at the top spot since 2010, who announced VW's bold initiative to grow its volume on an annual basis and sell 800,000 vehicles in the United States in 2018. But lack of product refreshes have slowed down that sales target. VW hasn't said why Browning is leaving, other than that he is returning to his home in the United Kingdom.It's the latest CEO shakeup following General Motors' announcement of Mary Barra succeeding retiring chief Dan Akerson. Horn's appointment appears to be effective immediately. Horn brings 23 years of experience working with Volkswagen to the table, having worked in both North America and Europe. Oddly, he doesn't have an official bio on VW's media site but we'll tell you more about him when we get that info. Advertisement Browning not only faced the task of making Volkswagen a volume player in the U.S., but also improving quality perceptions among American buyers. VW's American product was often criticized in product surveys, ranking near the bottom of several customer-satisfaction reports. Under Browning's rule, however, VW expanded production throughout North American to meet its 800,000 sales goal, including adding shifts at plants in Chattanooga, TN to build Passats, the only sedan VW builds in the U.S.
