Mach number Mach number In fluid dynamics, the Mach number (M or Ma) (; ) is a dimensionless quantity representing the ratio of flow velocity past a boundary to the local speed of sound. where: By definition, at Mach1, the local flow velocity is equal to the speed of sound. At Mach0.65, is 65% of the speed of sound (subsonic), and, at Mach1.35, is 35% faster than the speed of sound (supersonic). The local speed of sound, and thereby the Mach number, depends on the condition of the surrounding medium, in particular the temperature. The Mach number is primarily used to determine
Ford Mustang Mach 1 5800 rpm (4-speed automatic)." While on paper the 305 hp (228 kW) ratings seem a loss when compared to the 1999 and 2001 SVT Cobras which produced 320 hp (239 kW), in practice the Mach 1 engine produced similar peak horsepower and substantially more torque. Further differences included the use of Ford's solid rear axle with a 3.55 final ratio (As opposed to SVT's Independent Rear Suspension) also the availability of a 4 speed automatic in addition to the Tremec sourced 5 speed manual. Factory steel "Box" cross section subframe connectors were also added to increase chassis strength for both
