Volkswagen of America today reported that April sales fell 8.4 percent over a year ago despite strong results for its diesel-powered vehicles.

Sales for the Chattanooga-made Passat rose 2.7 percent in the month over April 2013 as VW’s clean-diesel version of the midsize sedan accounted for 42 percent of the total. Passat’s April sales were 9,315.

Total VW sales were 30,831 for April.
