Chemistry in my life...

While reading one of my favorite non-chemistry magazines the other day, I came across the advertisement pictured above for the Lexus RX hybrid. In the closeup picture, you can see why I've decided to include it here. Whenever I see chemical information or structures in real world situations, it makes me excited that non-chemists are getting a little exposure to what I work with every day. Usually the chemistry isn't great (and sometimes it doesn't even make sense), but at least our industry is getting some recognition. Although I tried to find some connection between the structures pictured and hybrid cars, I couldn't find one. Any ideas?
