Judging by what the mod looks like it's a conversation from either RFactor or GTR2. For both games someone made a Nürburgring mod which includes the Nordschleife and GP track as well as a few undetailed roads around the 'Ring. I guess the guy who converted the mod to BNG only converted the Nordschleife part.
