Bumpy road ahead for VW

Carmaker may find the going tough in China after pollution-cheating scandal

German auto giant Volkswagen AG, which is involved in a pollution-cheating scandal in the United States, may face a tough battle to retain its brand image and sales record in China, its biggest global market.

Volkswagen said on Tuesday that 11 million diesel vehicles worldwide are involved in the scandal of rigging US car emission tests. In a related development, the company's chief executive officer Martin Winterkorn announced his resignation on Wednesday.
