I'm halfway through reading Peter Dron's superb new book. I was interested in the 6 prototype cars listed in the book and thought I would see if I could find any videos on YouTube showing any of the early prototype cars mentioned. I have linked in 5 below. I would imagine they have all been posted before. The last video at the launch in Geneva you can see the rear disc brake on prototype number 1. https://www.youtube.com/watch?v=ZUU0ZjBB_1I
