Audi is named for the Latin word for 'hark' as in auditory. The reason was that the automobile inventor's last name was German for hark, Horch but he lost the right to make cars with that name when he was bought out by his partners. His son came up with the name.
The Audi symbol is four ceiling rings that reflect the four manufacturers of Auto Union. This Audi emblem signs the association of the brand Audi with others: Horch, DKW, Wanderer: the initial ring from at the left side represents Audi, the next represents DKW, the third is Horch, then the fourth ring is Wanderer.
