HMMWV Models

Something that I've wondered for a while now and haven't ever really been able to determine from the TMs or websites I've seen - What are the variations, changes, and improvements in relation to the HMMWV A0, A1, and A2 models?

There wasn't too much changed externally between the models. The A1 got a higher gear ration and the A2 got the 6.5L There was also some changes to the seats, grilles, parking brake handles, etc.

Here is a good link with info on the different models. http://www.militaryfactory.com/armor/detail.asp?armor_id=9

Thanks, thats informative.

I was just curious.

I know this is an old thread, maybe someone can answer though. The variations are body types- correct? I read through the link, but it mentions the engines. In my case- I had a 91 M1038 with the 6.2 now after replacing the engine with the 6.5 my variation is the same?

Yes, engine swap still makes it the same model.

M998 no winch
M1038 with front winch.

Yea, I get that, my question more was more between an AO, A1 or A2. I know the main difference between the other hmmwv variations was the upgraded 6.5. After some more research I don't think the M1038 was ever manufactured with the 6.5- is this correct? It only had the M1038 and the M1038A1 in 1994?
