Tokyo: Volkswagen's new chief executive Herbert Diess apologised at the Tokyo auto show today for the automaker's emissions-cheating scandal, promising to win back customer trust, and said it will delay the launch of a diesel vehicle in Japan.

The head of VW's Japan division Sven Stein, who appeared at the VW booth before Diess, bowed for several seconds in a Japanese style of apology. Diess made no bow.
