Chase Elliott and the No. 24 Hendrick Motorsport team have been hit with an L1 penalty following the first race of the NASCAR Cup playoffs at Chicagoland Speedway.
NASCAR stated that Elliott's runner-up result was encumbered due to "modification of components to affect the aerodynamic properties of the vehicle."
The result is the deduction of 15 championship driver and owner points, a fine of $25,000 for crew chief Alan Gustafson and a one-race suspension for both the crew chief and car chief (Joshua Kirk)) on the No. 24. The loss of points drops Elliott from sixth to eighth in the standings, 18 points above the cut line.
One of the issues may involve a piece of tape applied to the rear spoiler of the car in an effort to gain more downforce an therefore, an aerodynamic edge. A Reddit post from r/NASCAR included a video of what appears to be a crew member removing the tape following the race, seen HERE. The post also included a photo of the rear spoiler during the race, seen HERE.
But sources told Motorsport.com the aerodynamic manipulation was discovered in several areas of the car, not just the rear spoiler.
Hendrick Motorsports will not appeal the penalty, naming Kenny Francis as the interim crew chief for Kevin Hulstein as the interim car chief for Elliott at NHMS.
