Volkswagen’s Chattanooga-made Passat suffered another month of sharply lower sales compared with a year ago in December as the German automaker sustained an overall drop in sales while it works to fix its diesel-powered engines to comply with U.S. air emission standards.
Passat sales plunged 56.4 percent in December in the U.S. while VW posted a 9 percent total drop for the brand even as nearly all other carmakers reported big monthly gains.
Akshay Anand, a Kelley Blue Book analyst, said the Passat was hit by a model changeover, a lack of a diesel version to sell due to the emissions scandal as well as a soft market for midsize sedans.
