Don't tell Toyota, but Iron Man drives an Audi - at least in the movies ... campaign for the film's release that's scheduled for May 2 of next year.

The producers of Iron Man 3 undoubtedly have the No. 24 Audi RS5 DTM car driven by Adrien Tambay at last week's Hockenheim round to thank for the movie's record-breaking global opening.

"Fifty Shades of Grey" and "Iron Man" have added immeasurably to the brand's aura. In fact, you could now say that for characters of the Christian Grey/Tony Stark type, Audi is now the default choice.
