I too am interested (it reminds me of the new wayfinding typeface of the Milan subway).

Reminds me of Haas Unica.

Thanks, Jan, Unica crossed my mind as well, but the leg on the R is different.
This is Haas Unica:

First I thought it is Dalton Maag's Aktiv Grotesk, released a few days ago,
but I think it is not quite right.

Akzidenz Grotesk/AG Old Face has a straight R's leg, but other details are off.
From where is the sample?

From where is the sample?

Switzerland. :)

Jörg: thanks for the information about Aktiv Grotesk.
Riccardo: Florian is correct, the sample is from Zurich.

Zurich as in, made at ZHDK?
I'm wondering if it would be reasonable to surmise this could be custom/modified.
