Ford is reportedly developing a new naturally aspirated Mustang model to succeed the GT350. The vehicle is expected to feature a 5.2-liter or 5.4-liter V8 engine, with power output potentially ranging between 550 and 650 horsepower. This would position the car between the current 500-horsepower Dark Horse and the supercharged variants.
The upcoming model is rumored to feature a Tremec six-speed manual transmission. Technical enhancements may include upgraded brakes, specialized suspension components, and improved cooling systems for track performance. Additionally, the manufacturer might equip the vehicle with lightweight carbon fiber wheels as a standard feature, similar to the optional equipment on the Dark Horse.
The vehicle is unlikely to carry the GT350 nameplate, as Shelby American currently uses it for its own supercharged Mustang versions. Ford filed a trademark for the name Dark Horse Boss in early 2025, which is considered a potential candidate for the new model. The car is projected to reach the market in late 2027 as a 2028 model year vehicle.
