KGP Photography radars spotted Mustang tested on the streets which may be the 2015 GT350.
It features wider 19-inch tires (295/35) which probably is the result of more power. The hood has inlet for intercooler which hints to super or turbo charging. Front grille seems to generate more airflow. Two-twin exhaust tips hint for power too.
