The 2023 Mustang is the last of the S550 cars

Ford names the current Mustangs S550 vehicles, whereas the S650 will be used for the model year after that. 

Ford has essentially not modified the vehicle since it first appeared as a 2014 model. 

Traditionalists laughed at the S550's independent rear suspension, but everyone else adored it since it gave the car a handling ability 

that no previous Mustang had. Additionally, it boasts a comfy interior that lacks certain luxuries but still has the majority of the amenities

that most customers look for. With its twin gauges and antique air ducts, it unquestionably gives you the impression that you are driving a unique vehicle.
