How do symbols of a car relate to the name? What do they mean? Are they meant to appeal or describe? For example, why is Peugeot's symbol a lion? Why is Renault's a diamond? Why is Opel's a lightning bolt etc. Some obvious logos are Jaguar, Porsche (family crest), Eagle, Saturn, and Dodge Ram. Some are quite interesting like Chrysler, Mercedes, Infiniti, Mercury, Chevrolet, Audi. So many to list but for most, what is their meaning?
