The Enjoy Illinois 300 marks the first time the NASCAR Cup Series has visited World Wide Technology Raceway.  The 1.25 mile track in Madison, just outside of St. Louis has been hosting NASCAR sanctioned events since 1997, first with the NASCAR Xfinity Series, then the NASCAR Camping World Truck Series.  In 2014, the track became a permanent fixture on the NASCAR Camping World Truck series schedule.  The unique shape of the track should pose a challenge for the new Next Gen car, featuring 11 degrees of banking in turns 1 and 2, and 9 degrees in 3 and 4.  The first winner for the Xfinity Series was Elliott Sadler in 1997, and in 1998 Rick Carelli won the first NASCAR Camping World Truck Series race.
