Most car companies are hopelessly adrift. They have elaborate, dissonant design languages that couldn't be explained in a semester of lectures and exams. Some have been making their emblems bigger and bigger. Still others try to build synergy with other brands*.
Audi stands alone, and Volkswagen is a close second. This Audi sedan needed no explanation. From a distance, it was a beautiful Audi. As it got closer, there were no disparate elements that were the result of trying too hard or an approval process with too many stages. Audi is the essence of good design. While there is a lot of hard work, the result looks easy and obvious.
*Achieving such a goal is impossible. If you need synergy, you don't have anything to begin with. Both brands will look worse.
