We caught up with NASCAR Sprint Cup Champion Tony Stewart and his new crew chief Steve Addington at the Las Vegas round of the 2012 season.

With long races and a competitive field of 43 cars the relationship between a driver and his crew chief is the key to success.

There are 36 races a year in the NASCAR Sprint Cup and it is one of the most competitive racing series in the world. Even the top drivers are only lucky enough to get one or two wins per season. Tony and Steve explain to Mobil 1 The Grid, what it takes to make a NASCAR team work.
