The current 6th generation Mustang (S550) is available as a 2014-2017 FM series, or 2018-2022 FN series in Australia. Questions: Are car model 'series' codes (e.g. FM/FN) unique to Australia, (think of Falcon, Commodore, Valiant and heaps of Japanese cars), or are they also used world-wide?

Do generation 1-5 Mustangs have series codes or did the USA just go by model year (MY) to identify Mustangs?

lots of Fords
Interesting question, gut feeling says FM/ FN is Australia only, but hopefully someone wiser can confirm that.

I can't speak for all, but I know some in the industry use "body codes". The 5th, 6th & 7th characters in the VIN.

Yeah not thinking of a body code, e.g. a 1973 Falcon came in five body styles; sedan, wagon, coupe, ute & panel van … all being an ‘XA’ Falcon. Australia for some reason (perhaps other countries as well?) required a unique ‘reiteration’ code across each model generation for cars sold in Australia … for Ford, GMH, Chrysler/Mitsubishi, Toyota, Datsun/Nissan, Subaru, Hyundai etc.

Interesting question Graeme. I just googled “Mustang” and “FN”, and basically all the results were from Australian websites. Did a search on this website and it seems FM and FN are only referred to by Australians. I wonder why Ford Australia had the need to allocate model designations; government regulations?

I have always referred to FN in my profile, but no non-Australian has ever queried it. Maybe no one at all has taken any noticed of little old insignificant me’s profile, ha ha.

Anyway, FM/FN provoked a bit of a discussion here: https://www.mustang6g.com/forums/th...supercharger-re-long-term-reliability.171720/

While on the subject of terminology, why is the sixth generation Mustang referred as the S550, and the seventh generation model referred to as S650; shouldn’t they be more logically be S650 and S750 respectively?

The S550 refers to the 5 iteration of the original Mustang in 50 years making it the 6th generation. Interesting then the 7th should be something like S655 or 656 ish, due to 6 iteration in 55/56 years 🐎🐎🐎

It appears to be an Australian auto industry requirement going back to who knows when for cars sold in Australia, e.g. Holden FX, FJ, HR, HT, HQ … Falcon XR, XT, XW, XY … Commodore VB, VB, VL, ….. Valiant VC, VE, VH … Gemini TE, TX, TC … Subaru WRX GC, GD, GR … Hyundai i30 FD, GD, PD … Jeep Grand Cherokee ZJ, ZW, WK, WK2 … Nissan Pulsar N12, N13 …. and on it goes.

Interesting, but on that basis what do the previous codes mean?

Fifth gen = S-197
Fourth gen = SN-95

Are these just codes plucked out of thin air, a bit like (presumably) the Australian Mustang FM and FN model designations.

We need a code cracker, if only Alan Turing was still with us…

I'm no Alan Turing Code Breaker, however S550, SN95 etc are internal Ford development process designations, and FM & FN are unique Series designations to Australia, and have a unique Specification. Even British and Euro Mustangs are different, with slightly differing Power and standard Specs & Features to our Aussie cars.

I'll need to check in my Mustang book but they are related to the platforms. I believe they came up with the whole S550 as part of the big 50 Years celebrations and to pay homage to the previous 50 years.
