Ford has taken the Ford Mustang Dark Horse SC and turned it into an open-top grand tourer with a massive 795 hp / 806 PS and 660 lb-ft / 895 Nm of supercharged torque. Revealed ahead of the Woodward Dream Cruise, the convertible trades some of the coupe’s track-focused character for a more relaxed GT experience.

To handle the missing roof, Ford softened the suspension and added a magnesium strut-tower brace for extra chassis rigidity. The rear wing and hood scoop were also revised to suit the new aerodynamics. Carbon-ceramic brakes and carbon-fiber wheels aren’t offered, reinforcing the car’s grand-touring mission rather than chasing maximum track performance.

Power comes exclusively from a 5.2-liter supercharged V8 paired with a seven-speed dual-clutch automatic. Ford is aiming directly at buyers of the Porsche 911 Carrera Cabriolet, offering huge American horsepower and open-air V8 drama for more than $108,000 / €99,000.

Orders open this fall, with a claimed top speed of 150 mph / 241 kph. Can this Mustang really steal buyers from the Porsche 911 Cabriolet? Is sacrificing some track aggression worth the convertible experience?
