Quick Answer. NASCAR stock cars were previously allowed 850 to 900 horsepower; however, this amount was reduced to 725 horsepower in 2015. The lower horsepower is used with a tapered spacer, which is used in the NASCAR Nationwide series. In addition, the 2015 rules include a reduction of 6 inches on the rear spoiler, which cuts down on the downforce for drivers.
NASCAR planning horsepower reduction, other changes for 2015. NASCAR Vice President of Competition and Racing Development Robin Pemberton says more changes are on the way. NASCAR is planning on making significant engine package changes in 2015 to extend the life of Sprint Cup powerplants and reduce horsepower. And along with engine changes, there likely will be aerodynamic and tire changes for the Cup cars in 2015 as well.
