Please!

Sofia Pro isn't free.

URW Gothic L is a close match, but the dot over the i is squared and it only has four weights.

But it's under a goofy "You can modify it any way you want to, as long as you change the name" license so you can round the dot on the i or adjust kerning or whatever yourself.

Original is in Postscript, you can probably find converted TTF or OTF elsewhere if you need to.

I think I got my copy from GNU GhostScript 6.0

Look in the archive for gnu-gs-fonts-std-6.0.tar.gz

a010015l.pfb -URW-Gothic L-demi bold-r-normal
a010033l.pfb -URW-Gothic L-book-o-normal
a010035l.pfb -URW-Gothic L-demi bold-o-normal

You'll need the PFMs or AFMs as well depending on your system.

The real font please !

It's a commercial product. If you want it, buy it. If not, find a 'free' alternative. You wouldn't walk into a Starbucks™ and demand a free skinny latte, so why would you expect to get a free font family. (a coffee takes about 30 seconds to make, a font can take years of development)
Here's the real font…
