The Audi A7 Sportback h-tron quattro leaves nothing but water vapour behind – so we create advertising that also leaves

nothing behind: the disappearing billboards. With the help of state-of-the-art technology, we project the car and our

message onto clouds of water vapour, thus conveying a timeless message in a very time-limited way.

This Audi emits nothing but water vapor, so its billboards are made of that too.

The A7 Sportback h-tron quattro is a genuine Audi – at once sporty and efficient. It covers over 500 kilometers (310.7 mi) on one tank of fuel – and its exhaust emits nothing more than a few drops of water: The A7 Sportback h tron quattro uses a powerful, sporty electric drive with a fuel cell as its energy source, in combination with a hybrid battery and an additional electric motor in the rear.

H-tron shows that the gasless future of driving doesn’t have to suck.

The action leaded to an increase in the interest of Audis future driving technologies. The disappearing billboards alone were mentioned over 6.660 times on Google.
