Information for/from other sections

There are some similarities between the final drive/differential for Internal Combustion and Electric vehicles, should we make a separate page just for final drive, link the electric section here (once it's been created), or just copy/paste?

Also as was mentioned in the article, there is overlap between the electronics and validation sections, I think (as mentioned by someone else) we should add a link to the appropriate article and leave a high level simple explanation.

Definitely need another page for Differentials

definitely agree that the topics that are equivalent between EV/ICE should get their own page and just be linked to both. I think it should be reasonable that drivetrain is similar enough between ev/ice that one article can fit in both, not sure about direct drive/ in hub motors, but it shouldn't be that hard to tackle honestly

testing/validation definitely deserves an article by itself, its so general, i think the bit in the drivetrain section should be specified to testing procedures and stretegies for drivetrain and leave all the philosophising about validation to its own article
