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.
What HP actually measures, is the maximum rate of acceleration and the top speed of the car. On the other hand, Brake Horsepower measures the HP of an engine without considering the loss in power that is caused by some parts of the engine, like the generator, gearbox, water pump and other auxiliary parts.
