The Audi badge the 'Four Rings' is the emblem of one of the oldest car manufacturers in Germany.
It symbolises the 1932 merger of the four independent motor-vehicle manufacturers: Audi, DKW, Horch and Wanderer.
Together with the NSU brand, which joined in 1969, these companies are the roots of the present-day AUDI AG.
After the World War II, the Audi name -- which is Latin for 'Hear!' -- disappeared, but was revived in 1965, using the four rings as a logo.
Also, the name is sort of a pun on 'hoerch', German for 'hear', name of one of the founders.
The company itself is more than a century old.
The new logo, released in September 2009 changes the font and also improves on the 3-dimensional aspect of the rings.
