F1 driver Sebastian Vettel
is renown for his multiple FIA Formula 1
World Championships, but holds a lesser-known title for Infiniti
, one of the sponsors of his racing team. As 'director of performance' for Infiniti
, Vettel is reportedly transferring his knowledge from the track to the road in an effort to improve Infiniti vehicles. We see for ourselves during a lap with Vettel at the Nashville Superspeedway, then head to the U.S. Grand Prix
in Austin, Texas for a conversation with global director of Infiniti F1 Andreas Sigl.
