The Audi A7 Sportback h-tron is one of the few hydrogen fuel cell cars that actually plugs in (we think all fuel cell cars should be plug ins).  Unfortunately, it's purely a concept at this point in time, but that hasn't stopped Audi from beginning to market this revolutionary car.

Seen here is Audi's first attempt at advertising the A7 h-tron.  The ad is described by AdWeek as such:

"Innovative products deserve advertising that itself is innovative—embodying the promise of what's for sale in the way it's being sold. This Audi campaign from German agency thjnk does a nice job of that."

"The Audi A7 Sportback h-tron uses a fuel cell coupled with a hybrid battery and additional electric motor in the rear. Notably, nothing but water vapor comes out of the exhaust. And so, Audi created billboards that similarly leave nothing behind."
