AmericaJR’s Jason Rzucidlo was LIVE at the Las Vegas Motor Speedway for the first of two NASCAR test sessions. Seven-time NASCAR champion Jimmie Johnson, Las Vegas-born titlists Kurt Busch (2004) and Kyle Busch (2015), as well as 2012 champ Brad Keselowski, will be on-hand for the test, which will be open to the public free of charge. LVMS grandstands and Pit Road will be open and available to watch all the on-track action. The two-day session will be the first time drivers will test NASCAR’s new aerodynamic package – designed to foster tighter racing – at LVMS. Throughout the day, NASCAR will test the new package using groups of cars drafting in packs – in addition to the standard single-team testing.
