Ford has just confirmed total output for the most powerful Mustang ever, and it’s higher than the automaker promised. The 2025 Ford Mustang GTD will make 815 horses, confirming it has eaten all of its oats and then some. It will also gallop faster than 200 miles per hour, which means it’s also the fastest street-legal Mustang that Ford has ever made.
When Ford first announced the Mustang GTD, it was still working on the final calibration for this thoroughbred’s heart. Ford said it was targeting at least 800 horsepower from the supercharged 5.2L V8 under the uber-Mustang’s long hood.
Ford smashed its target. The final number is 815 horsepower along with 664 pound-feet of torque. Ford has the certified dyno charts to prove it.
5.2L Dry-Sump V8 for Mustang GTD
The GTD’s powerplant started with Ford’s Predator V8, the one it used in the now-gone Shelby GT500. It’s so different, though, with changes including a new intake and a titanium exhaust, a smaller supercharger pulley for more boost, and even a redline 100 rpm higher than before thanks to a dry-sump oiling system, that Ford isn’t using that name anymore.
It might not quite beat the bonkers figure of the upcoming Chevrolet Corvette ZR1 and its 1,064 horsepower, but it still beats out any roadgoing Porsche 911, and it dusts the 760 horses of the next-most-powerful Mustang (that GT500).
We’ve been laser focused since day 1 to make Mustang GTD the first-ever supercar with world-class performance and the soul of a Mustang GTD’s heart is its supercharged 5.2-liter V8, packing more horsepower per liter than the Porsche 911 GT3 RS.
