BMW AG fell as much as 9.3 percent in Frankfurt after a German magazine reported that the X3 xDrive 20d sport utility vehicle emitted as much as 11 times the European limit for air pollution in a road test, adding to concern that the investigation weighing on Volkswagen AG may spread to other manufacturers.
 The SUV was road-tested by the International Council on Clean Transportation, the same group whose tipoff led U.S. regulators to investigate a gap between Volkswagen AG diesels’ emissions in tests and on the road, Germany’s Autobild reported. BMW said that there’s no system in its cars that responds to tests differently than it would operate on the road.
