Tested: The Mustang GTD's Numbers Aren't Astonishing, but Its Performance Is

The Mustang GTD's numbers aren't astonishing, but its performance proves the point. In the tested configuration it weighs 4,411 pounds, roughly the mass of a Kia Telluride. As tested, the car commands $438,200 and features a heavily revised drivetrain and aero, including a Predator 5.2-liter supercharged V-8 delivering 815 horsepower and 664 lb-ft of torque. It is paired with a Tremec dual-clutch transaxle, while Multimatic supplies the front and rear dampers and a carbon-fiber roof and body panels. Ford sends the Mustang GTD’s body-in-white to Multimatic in Markham, Ontario, after leaving Flat Rock, Michigan, where front and rear ends are replaced with carbon-fiber and aluminum components on a tubular steel rear subframe. The GTD is widened by over 6 inches to 81.7 inches and rides on 325 front and 345 rear Michelin Pilot Sport Cup 2 RS tires on magnesium rims, with a plexiglass view into the rear suspension and mirrors that barely protrude beyond the body. Altogether, the package yields a heavy but exceptionally capable track machine.
