If you're referring to the Super Competition graphic, I did not use any font at all. I have an original decal that was scanned. It is high enough in resolution that one could probably use the Image Trace command in Illustrator and come up with a moderately decent vector file, the main caveat being that you will undoubtedly have some "sweetening" and cleanup to do around all those delicate thin lines.

I am confident in saying that nearly all of the Peugeot logotypes have been specifically designed and drawn, and do not originate - at least not directly - from a standing typeface.
