The ATX is the CD4E, which is also used by some Mazda vehicles. Do a google search on CD4E and you'll find some info on the background and its manufacture (Batavia, OH).
The MTX-75 is also used on the Focus, in a different housing. Shows how Ford likes to use the same major powertrain components across platforms (just like the Zetec being in Escorts and Foci). Cross-platform commonality makes the parts cheaper (higher production quantities makes the fixed cost lower per part) and makes design cheaper (by using an already designed part, you save development costs).
Also, you can throw in some facts about the Mondeo and New Edge Cougar being the same platform.
