Citroën m35

Here's a fragment of a short film about the coöperation between Citroën and NSU, the 16 minute film can be seen through the link below this article.

The fragment shows a scene which I haven't been able to find before; the testing of M35-technique under an Ami 6 Berline. They're driving on the circuit of Monthléry, near Parijs, probably somewhere in 1968. Will this testbed still exist?
