There's a comparative review of the Fiesta ST against the Subaru BRZ on autoguide.com.
Autoguide.com has a nice direct-comparison review that pits our favorite, the 2014 Fiesta ST, against the Subaru BRZ, in a track-centric sort of way. While they end up giving the nod, by the barest of margins, to the BRZ (which won the lap time race by 0.3 sec), they do give a decent measure of respect to the FiST. I evaluate the results of their comparison more favorably for the Ford, and in the end I find that their review serves once again to reinforce my happiness with my decision to go with the Fiesta ST. This car does for me what few other cars can even try, all things considered. And especially when including comparisons of the interiors of the two vehicles, the Fiesta ST wins in a runaway.
