I was 3 years old, and we had a very rich neighbor in Berlin who drove a Mercedes sports car. I remember standing behind this car, admiring the trunk, how nicely shaped it was, for an hour. That shape has never left me - I could design it today!

1973 was the first gasoline crisis in the world. That year, I designed the first aerodynamic truck, eating 40 percent less fuel. I put it on exhibit everywhere. It was 30 years ahead of its time. Nobody is building it today, and everybody still has problems with their boxy cars and trucks eating up fuel.

I'm a very peaceful man. In the '80s, I was the chief designer at Thyssen, one of the biggest companies in Germany. But when they asked me to design armored vehicles, tanks, and submarines, I quit overnight.

You see, if you are 30 years ahead of your time, you will always have difficulty speaking with the bosses in the industry. They are too conservative.

I learned to ask myself questions like: Why is something made the way it is? Why does a motorcar look like it does? Is it right or wrong? What is an airplane? Why is it shaped like that? Then, later, I became a diver and studied subaquatic life and the streamlining of sharks and manta rays. Any fish is superior to the shapes we humans have invented - and unchanged for 250 million years, imagine!

It is absolutely the central theme in my design philosophy - that life is erotic, period. The female body is one of the most extraordinary designs ever done in this universe.

Look at nature - look at birds, look at fish. Things that look good, work good. People don't get the message of ergonomics.
