NASCAR to announce engine changes by All-Star race

Expect NASCAR to announce engine changes before this year's All-Star race.

NASCAR's senior vice president of racing operations has said that a formal announcement on engine changes for the 2015 Sprint Cup Series season will come before next month's Sprint All-Star Race at Charlotte Motor Speedway. At a sponsor summit for Iowa Speedway, Steve O'Donnell said that the final overall racing package for 2015 would also see changes involving downforce, aerodynamics, and tires.

In additional comments to The Des Moines Register, O'Donnell said that teams have already been notified of where NASCAR was going with the changes and that the process of finalizing the 2015 engine package was underway. O'Donnell wouldn't divulge exact details of the package, but did perhaps show a glimpse of how drivers would have to adapt to it.

"If you combine the aero package with that [reduction of] horsepower [and] allow some aero changes with the engines going into the corner, drivers have to get off the gas and they're able to maneuver around a little bit more," O'Donnell said according to the Register's Chad Leistikow. "Combine that with Goodyear and a little softer tire, now you're able to move around a little bit more." NBC Sports
