Ford has had adaptive fuel strategies in their cars for years now, they just do not advertise it. Many of their engines gain significant horsepower from premium fuel. The ECU allows more timing, etc.

I remember that Mazda on the CX9 (which is a 3 row Edge with the 3.7 liter engine instead of the 3.5) actually advertised that horsepower went from 273 to I believe 298 with premium fuel (the CX9 uses the non-Ti-VCT version of Ford's 3.7).
I just read my 2013 SE's owners manual and it recommends using 87 only. I didn't see a phrase that stated premium would increase performance. Just may only be found in the 2012 second version.
