2025 Mustang Dark Horse | 500 HP 
The Dark Horse Mustang carries an additional $18,000 premium over the base Mustang GT, and according to our friends at MotorTrend it is quite possibly one of the best V-8 muscle cars they’ve ever tested. While the Dark Horse’s 5.0-liter V-8 has been beefed-up to put out 500 hp, reducing the Mustang’s 0–60 time to 3.7 seconds, it is the new chassis, tires, and brakes that create all the excitement. This horse can stop from 60 mph in an astounding 86 feet, the shortest distance from a production car ever observed at MotorTrend. Also getting big kudos from the staff is the Dark Horse’s much beefier Tremec six-speed manual, which is not only physically stronger but also more confidence-inspiring than the standard Mustang GT’s MT82-D4 six-speed box. Dark Horse also has performance-oriented no-lift shifting and rev-matching
