Avenir Black  Sugerida por frd 

Avenir Black could be a good one to start, the "r" are slightly modified though.

It is Avenir® 95 Black as drf_ stated...

Both "r" characters have a slant that is added.

When I tried to use drf_'s link it didn't work so I attached a new one.

Yeah, it seems like MyFonts search is down at the moment. I'll check later to make sure the link works when it's up again.
