RE: mule car vs. protoype
Off-tool means that it is a part that is made on the production dies/tools, but not neccessarily at the production rate, and it may not meet the spec. That's what you'd use at your confirmation prototype build, typically.
Off-process is not a term I've heard before but random googling indicate sthat it is parts off the production tool, /and/ using the intended production process, and line rate etc. I don't know whether they'd be in spec, or if this is what you'd use to establish capability.
Cheers

For instance we routinely alter weights, CG height , and some panels, suspension geometry, spring rates, shocks, sta bars, steering racks for mules.

RE: mule car vs. protoype
In my own experience, the term 'Mule' has only been applied to vehicle where the purpose of the body shell is to act as a vehicle to carry engine/transmission/suspension development actions. Hence the Mule just carries the parts.
Cutting and carving of the body to pacakge a new engine/transmission/suspension usually means that the body is not a valid tool for final body structure validation.

Most mules are for ride and handling, roadloads, and powertrain/driveline work.
This thread hasn't mentioned bucks, which are stationary mules, used for packaging and interiors and so on.

annafergusen1980, can we take it that you are involved in a vehicle development programme in a professional way and this is your first experience of them?
I see you've also asked questions about 'Engine manufacturers' and 'Product planning in GM'.

RE: mule car vs. protoype
Thank you Bill for your comment on that "off-process" thing and I can see you are keeping my track from that product plannig thing which was for quite some time ago.

If you combine a mule and a buck for purposes of mock-up does it produce a muck-up???
