The 2003 model year

Overview

A banner year. The Mach 1 name returned on a 305 hp Ram Air 4.6 DOHC with a functional Shaker hood scoop and a retro interior — and the SVT Cobra came back supercharged. Nicknamed the "Terminator," the 2003 Cobra used an Eaton-blown 4.6 L DOHC making 390 hp, a Tremec T-56 six-speed, and an independent rear suspension — the most powerful factory Mustang to date. (Horsepower figures are SAE net.)

Year over year

What changed

  • The Mach 1 returned — 305 hp Ram Air 4.6 DOHC, functional Shaker scoop, retro comfort-weave interior, Magnum-500-style wheels.
  • The supercharged "Terminator" SVT Cobra debuted — Eaton-blown 4.6 DOHC, 390 hp, T-56 six-speed, IRS, forged internals.
  • A Centennial (Ford 100th Anniversary) appearance package was offered (black, parchment leather).
  • V6 and GT carried over.

Worth knowing

Notable

  • The 2003–04 supercharged "Terminator" Cobra (390 hp) is the most coveted modern fourth-gen Mustang and a blue-chip tuner car.
  • Return of the Mach 1 (9,652 built in 2003) with its functional Shaker scoop.
  • Most powerful factory Mustang up to that point.

Living with it

Reliability & ownership notes

  • The Terminator's iron block and forged rotating assembly make it very strong and a favorite tuner platform; the Eaton supercharger and its intercooler add maintenance items — check for boost/cooling-system service.
  • The Mach 1's DOHC engine and the Cobra IRS are both buying checkpoints; verify documentation given the premiums these carry.
  • Standard New Edge body and modular-V8 notes apply (convertible seals, front-end rust).
