Applied to the 2010-2012 model years, the S-197 II Ford
Mustang’s first update came with refreshed styling and a V8
uprated to 315 hp for MY2010, but the entire engine lineup was
replaced the next year, with a brand-new aluminum 3.7L base
Duratec V6 with 305 hp at the bottom of the range, and a 5.0L
Coyote V8 with four valves per cylinder and 412 hp for the GT.
