The top speed of the Ford Mustang GT varies slightly depending on the model year and specific configuration. For the 2024 Ford Mustang GT, the top speed is limited to 155 mph due to an engine governor, despite its 5.0L Ti-VCT V8 engine producing 480 hp and 415 lb-ft of torque. In earlier models, such as the 2022 Ford Mustang GT, the top speed was reported to be 163 mph, thanks to its 5.0 V8 engine producing 450 horsepower. It's important to note that these speeds are governed for safety reasons, as standard components like tires are not designed to handle higher speeds.
