Frankfurt auto show: Diesels improve, but will people buy?

A Volkswagen Touareg stands upside down in front of the fair ground of the IAA Motor Show in Frankfurt, Germany, Wednesday, Sept. 13, 2017. The environmental organization Greenpeace installed the car the day before to protest against the car industry. From frighteningly fast hypercars to new electric SUVs, the Frankfurt auto show is a major event for car lovers wanting to get a glimpse of the future. (AP Photo/Michael Probst)
