As I research and study advertising, I understand that the simple point of the ad must be clear for the niche audience. Mercedes is famous for its German perfectionism in their engineering and the very creative design of their automobiles. On this particular ad the associations are clear even if you don't understand them at first glance. The left is probably associated with the creativity in design and the right is for the research and engineering. Another nuance is the left Einstein is less formally dressed than the right one. The ad is black and white and the point is clear.
