Frankfurt -- Volkswagen AG's premium-brand arm Audi plans to invest €11.6-billion ($18.7-billion) during the next four years, the company said yesterday following a meeting of its supervisory board. Roughly 80 per cent of the total investments are expected to flow into developing new products, which include brand new models such as the Q7 off-road vehicle dubbed the "Pike's Peak" as well as additional derivatives of its current models. A spokesman for Audi declined to comment on which projects had passed their feasibility studies, such as its Audi Le Mans high-performance concept sports car. VOW (Frankfurt) fell 36 cents to €33.95.
