Nissan North America was the only major automaker that used fleet sales to boost its U.S. volume in October.
Nissan's fleet sales jumped 69 percent for the month to 13,200 units from 7,900 a year earlier. Its retail volume rose only 12 percent, but fleet pushed the overall sales gain to 18 percent, well above the industry sales gain of 8 percent.
Fleet was still a modest 16 percent of Nissan's sales mix last month, up from 11 percent in the same month last year. But other major players reduced their fleet mix. Fleet unit volume was flat or fell at Toyota Motor Sales U.S.A., Hyundai-Kia, General Motors and Chrysler Group. Ford Motor Co.'s fleet sales rose 1 percent, but an 8 percent retail increase trimmed its overall reliance on fleet.
GM, Chrysler, Toyota and Hyundai-Kia have reduced their fleet mix so far this year. Ford's fleet sales are up 12 percent, close to its 11 percent retail increase.
But Nissan has boosted 10-month fleet sales 29 percent to 121,900 units, even more than its retail growth of 13 percent.
Fleet sales for the Big 7 combined were flat in October at about 150,000 units.
American Honda is the only automaker in the Big 7 that does not have a central fleet office, and fleet activity conducted by individual dealers is assumed to be 2 percent of total sales.
