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.
For renting cars there's also a better way. And if you're an Audi fan and live in San Francisco, that way is actually quite superb -- if you can afford it. Launched over a year ago in beta and still under the radar, Audi on Demand is the automaker's premium car rental service. As you'd expect, it's for Audis only.
