S550

2023 Ford Mustang Facts

The final S550 model year carried EcoBoost, GT, and Mach 1 configurations into an April 2023 transition; Ford's full-year production and sales totals mix S550 and S650, so they are not final 2023-model-year production.

Reported S550 transition production, January–April 2023
19,828

Model / Body Style Units Type
Mach 1 Disputed: 4,000 Special edition

The leading 19,828 is transparent arithmetic: 5,964 + 5,410 + 7,561 + 893. Its S550 boundary comes from a secondary report, not a Ford generation ledger. Ford's 61,165 full-year output and 48,605 U.S. sales mix S550 and S650; Mustang Mach-E is excluded from this family slice. The 53,159 and 10,961 alternatives remain disputed and non-additive.

Why published totals differ

Reported: 19,828 MustangCarFacts arithmetic from Ford monthly cells; generation boundary from Motor1's attributed report Flat Rock Mustang production in Ford's January-April 2023 monthly cells, interpreted as generation-transition S550 evidence with a separately reported April 6 cutoff. 5,964 + 5,410 + 7,561 + 893 = 19,828. The generation boundary is secondary reporting, and Ford does not label every cell by generation, so this is not a verified final model-year ledger.
61,165 Ford Motor Company Mustangs assembled at Flat Rock during calendar year 2023, mixing outgoing S550 and incoming S650 production. This plant total is not a 2023-model-year or S550-only count.
48,605 Ford Motor Company United States Mustang sales during calendar year 2023, excluding Mustang Mach-E and spanning both S550 and S650 deliveries. Sales are deliveries, not production; Ford reports Mustang Mach-E separately.
Disputed: 53,159 Fixed Wikipedia sixth-generation Mustang revision Fixed secondary compilation's United States sales figure for the 2023 row. Conflicts with Ford's final 48,605 calendar-year U.S. Mustang sales.
Disputed: 10,961 MustangSpecs MustangSpecs report labeled first-quarter 2023 Mustang production. Conflicts with Ford's January-March Flat Rock sum of 18,935 and lacks the underlying ledger.
