Another German automaker was dragged into the scandal over harmful emissions from diesel engines Thursday -- at least on the stock market. Shares in BMW (BAMXY) slumped 8% to their lowest level in two years after a German magazine reported that at least one model had breached European pollution limits by a huge margin in road tests. Auto Bild said the BMW X3 xDrive 20d had produced 11 times as much nitrogen oxide as permitted in independent road tests conducted by the International Council on Clean Transportation. via CNNMoney (London)
