Remember that awesome Hotwheels track you built when you were a kid? The one that went from the bedroom all the way down the stairs and into the kitchen? Yeah, that was cool, but this one tops it. Meet the setup Hotwheels' is calling the largest wall track in the world.

Hotwheels rigged up the monster at this year's fan fest in Barcelona, showing off all its seven story glory to 40,000 adoring Hotwheels fans. Unfortunately the video is in Italian Spanish (note: I am an uncultured swine!) but the joy of tiny cars can bust through a language barrier no problem. My only hope is that next time, they'll vary up the track types a little bit. Oh, and go for like 70 stories. Please? [Autoweek]
