Mustang Generation Nicknames: What Do They Mean?

Mustang Generation Nicknames: What Do They Mean?

Last Updated August 4, 2019 | Chris Cervenka

If you’re new to the Mustang realm, you may have heard the terms “S197” or “SN95” in passing and wondered what they mean when it comes to the Ford Mustang. These are nicknames assigned to the platform by Ford before they’re released. You can think of this as “code” when Ford is in the process of research and development for the up and coming body style. Cool, right?

Once the new body style is released, the “code name” or “nickname” sticks with that body style. From that point forward, many enthusiasts and people in the automotive industry refer to cars within that body style by the codename. These nicknames really didn’t become well known amongst the public until the Fox Body platform and are still widely used today.

Fox Body: 1979-1993 Mustangs

1979 was the birth of the Fox Body Mustang platform. Still widely used today for drag racing and even road course events. Due to its lightweight design, the Fox Mustang has the ability to be nimble around the turns with the right suspension modifications and extremely quick in a straight line due to its attractive power-to-weight ratio.

The birth of the 5.0L Modular “Coyote” Engine was also an iconic moment in Mustang history with over 400 horsepower from the factory on a GT beginning in 2011.
