The '04 Mach 1 was rated with 305 horsepower, but dyno results showed that they really made closer to 320 at the crank. They included 17-inch, 5-spoke Heritage (Magnum 500-style) wheels with the galloping pony logo inspired by the 1969-1973 Mustang’s Mach 1 wheel design and 1960s-style “comfort weave” trimmed black leather seats. Volume was limited to fewer than 5,000 copies, making it even more rare than the 2003 edition. The Machs were available in Azure Blue (Mach 1 color only), Black, Competition Orange (new for '04), Dark Shadow Grey, Screaming Yellow (new for '04), Torch Red, and White.
