Yes, volvo in Latin means 'I roll over', which isn't too likely to happen with a Volvo, unless Barb's at the wheel
I guess the Latin connotations of turning wheels etc. may have encouraged the choice of the name,
but it was mainly the association with Nordic magic.
Latin vulva (more usually volva iin Classical Latin) isn't related to either vǫlva or volvo -
it was originally a word for a husk, shell, then came to be used for an animal's womb
(especially a sow's womb, which was a favourite delicacy of the Romans) -
its use for the 'gateway' to a human female's womb
(which is a favourite delicacy of the Dolcettians)
I think only goes back to early modern medicine,
and might have been influenced (apart from male ignorance of female anatomy)
by the unrelated word valva, meaning a doorway,
and especially Roman-style folding doors (and is the origin of 'valve').
