Nissan has decided to showcase its special nano-paint technology that repels mud and everyday dirt on a Nissan Leaf. They call it the world's cleanest car, in a reference to both its zero-emission to its self cleaning paint.

The exterior was treated with superhydrophobic and oleophobic paint called Ultra-Ever Dry. It was designed to repel water and oils and it creates a protective layer of air between the paint and environment.

“The 100 percent electric Leaf provides the perfect canvas for this new, advanced paint technology," said Pierre Loing, vice president, Product Planning, Nissan North America, Inc. “This is one Leaf that never has to stop at gas stations – not even for a car wash,” he added.
