Nissan has built a Batman-themed Juke

To get in, it's not actually required to tap three keys on a piano like Bruce Wayne's cave. To access the confidential side of the building and the main design studio, you just speak to a nice receptionist, who escorts you to something known internally as the ‘Power Wall'.

I was greeted with a five and a half metre, super hi-res, cinema-spec screen where designers digitally model full-size cars. The Qashqai, Juke and sexy Infiniti Emerg-E concept were all designed in this room. And now it was our turn.
