Check out what pure, unadulterated joy looks like. That's F1 racing champion Sebastian Vettel behind the wheel of the Ferrari FXX K. Vettel will be driving a Ferrari during the 2015 F1 season, but on this particular day the German took the track-only hybrid for a spin at the famous Fiorano test track, owned by Ferrari and located near the Italian town of Maranello. The highlight of the clip is the moment Vettel, in unleashing all 1,036 horses under the hood, spontaneously exclaims "Mamma mia! It goes like a rocket!" The test drive was set up for a photo shoot to appear in the next issue of Ferrari's official magazine. Not bad for a work-related obligation.
