Audi started the biggest investment program in its history last year as part of its effort to overtake BMW as the world’s largest premium automaker by 2020. The Volkswagen Group subsidiary will spend 24 billion euros over the next five years to add new products, lightweight technologies, alternative drivetrains and improve connectivity. Audi CEO Rupert Stadler is particularly bullish about the automaker’s fast-growing SUV lineup. He explained why in an interview with Automotive News Europe Editor Luca Ciferri.
