2003 Ford Mustang Facts

Overview

• Ford built 153,367 Mustangs for 2003, matching both MustangSpecs' overview 'Units Produced' field and its detailed body/trim table exactly.
• The SVT Cobra gained an Eaton-supercharged 4.6L DOHC V8 rated at 390 hp.
• The Mach 1 returned with shaker-scoop styling and a naturally aspirated 4.6L DOHC V8.

Production Breakout

MustangSpecs' overview 'Units Produced' field and its detailed nine-row body/trim table agree exactly at 153,367. A prior editorial pass recorded an unattributed alternative of 140,350, but that figure could not be traced to any inspected source upon re-fetch and has been removed from public content; see the mustangspecs-2003 dossier.

Specifications

• MustangSpecs' own Dimensions & Weight table reports 183.2-inch length, 73.1-inch width, 53.1-inch height, and a 101.3-inch wheelbase for the 2003 Mustang, explicitly stated by the page as unchanged from 2002.
• Reported curb weights by trim: V6 Coupe 3,069 lb; V6 Convertible 3,208 lb; GT Coupe 3,241 lb; GT Convertible 3,379 lb; Mach 1 3,465 lb; Cobra Coupe 3,655 lb; Cobra Convertible 3,780 lb.

Options & Packages

Counts distinguish verified production records, attributed reports, disputed figures, announced limits, and figures that do not survive in available records.

Buyer Identification

• Use the 17-character VIN, door certification label, buck tag when available, window sticker, and build sheet. For SN95 and New Edge cars, VIN/body codes separate coupe/convertible and engine family, while options and special packages usually require the window sticker or SVT certificate.
• Verify Cobra, Cobra R, Bullitt, Mach 1, 35th/40th Anniversary, Spring Feature, Centennial, and Roush/Saleen/Steeda claims by matching the VIN, model code, engine, brakes, wheels, interior, exterior parts, serialized certificate, and package-specific color or trim.

Additional Notes

• SN95 and New Edge color verification should combine the door label, window sticker, and special-model records: Mystic and Mystichrome Cobras, Atlantic Blue and Zinc Yellow New Edge cars, Bullitt Dark Highland Green, Mach 1 stripe/interior combinations, and SVT certificates are where rare combinations usually show up.
• The 2003-2004 Terminator Cobra became one of the most modification-friendly factory Mustangs of its era.
• The supercharged 2003 Cobra's 390-hp rating and forged-engine reputation created the Terminator nickname's lasting enthusiast weight.
• The Mach 1 return paired Shaker-scoop nostalgia with a 32-valve modular V8, giving New Edge buyers a naturally aspirated alternative to the Cobra.
• The 10th Anniversary Cobra package marked a decade of SVT Mustang production with distinctive wheels, trim, and interior accents.
