Reports: 2015 Sprint Cup rules package expected to be released on Tuesday


It sounds like we won’t have to wait much longer before seeing what the 2015 NASCAR Sprint Cup Series rules package will look like.

Lee Spencer of reports that the sanctioning body will release the rules package to teams on Tuesday. Additionally, Fox Sports’ Bob Dillner reported during this morning’s pre-race coverage that the teams would be on a conference call on Tuesday with NASCAR to discuss the changes.

Spencer reports that garage chatter about the new package has centered around a two-inch reduction to the rear spoiler, a sizable decrease of 125 horsepower, and different gear rules.

However, Dillner also mentioned in his own report that teams believe a change in the tire compounds may occur.

Last month at Michigan International Speedway, 10 teams each ran through six different aero configurations. Power optimization was also focused on during the session; USA Today and NBCSN contributor Nate Ryan reported that teams tested horsepower configurations of 850, 800, and 750.

The goal of all of this remains the same for NASCAR: Create a package that can improve racing on the series’ bread-and-butter intermediate tracks. While the Generation-6 cars have certainly had their moments, it can be argued that passing remains a general issue.

Following the Michigan test, several drivers expressed their hope to get a configuration with less downforce. Joe Gibbs Racing’s Denny Hamlin in particular was a very vocal supporter of a configuration run during the test that cut the downforce levels by 30 percent.

But while a smaller rear spoiler would give the drivers less downforce, it sounds like NASCAR is set to follow through on a horsepower drop for the engines, which currently churn out around 850 to 900.

NASCAR CEO Brian France hinted in April that such a change was coming, and a few days after, the sport’s most popular driver, Dale Earnhardt Jr., expressed his belief that a drop was inevitable.
