RE: What is a car grid ?
The origin was somewhere in front of the car, car centre line, , and somewhere below ground level, in at least one car company.
Nowadays the location of the origin is still anybodies guess, but at least we've settled on x as longitudianl, y as lateral, and z vertical, with a 100 mm grid, although of course the grid as such is much less important now.

I know GM had at least three XYZ coordinate systems. Fisher body was L=X, H=Y, W=Z. That was because we started a design with a blackboard drawing to make sure all the chassis components and people would fit inside the styling. XY for the side view made sense. The motor divisions used XYZ=LWH because a lot of their chassis layout was done in the plan view. Chevrolet used +X pointing towards the left. We settled on the motor division convention so that we could share FE modeling easily. / dave
