MILAN (Reuters) - Volkswagen is not interested in a tie-up with rival Fiat Chrysler as the German carmaker’s efforts were all focused internally, Chief Executive Herbert Diess told Il Sole 24 Ore and other two newspapers.

Asked whether Volkswagen was interested in Fiat Chrysler’s premium brands Alfa Romeo and Maserati, Diess said his group “already owns luxury brands”.
