If you are well up on Greek Mythology maybe Clio means something, or if you are familiar with the works of Carlo Franzoni you may well make the connection to his "Car of History" sculpture in the US Capitol. In general though its a fairly meaningless word which conveys little about what has been a very successful car.
Thinking on fron that VW's little successes, the Golf and the Polo probably also fit into the pretty meaningless category. You may expect that the Polo would be slightly more exclusive than the Golf in a literal sense comparing the two sports, and neither sport conveys much about the characteristics of the car.
So in traditional FCF off-topic fashion we have to dig into the world of Motorcycles for my best ever name...
The Velocette Venom! No there's no way on earth that could be a "commuter bike" and its definitely going to be a bit of a wild thing!

Go on what names do you like?, what are hideously boring? and where did the manufacturers dig them up from?
