NASCAR fines: Money collected from fines issued to drivers will now go to the NASCAR Foundation, which supports a variety of charitable initiatives. Previously, fine money was added to the season-ending point funds paid to drivers based on their finish in the point standings.
Revisions to pit road rules:

Over-the-wall pit crews in NASCAR's three national series will be able to hand push their car no more than three pit boxes away from their assigned pit box - limiting the crews to the same three-box length for pushing as the vehicles can drive through getting onto pit road.  Outside tires that have been removed from a vehicle during a pit stop can no longer be free-rolled from the outside of the pit box to the wall. The tires must be hand-directed to the inner half of the pit box before being released.

Fuel cell size: All three national series will run the same up-graded fuel cell - which is another safety feature - and is the same fuel cell used in 2007 by the NASCAR Sprint Cup Series.

Tire usage at non-sanctioned tests:  Teams in all three national series will receive an allotment of tires to use for non-NASCAR sanctioned tests. NASCAR Sprint Cup Series teams will have access to 200 tires over the course of the year; NASCAR Nationwide teams will get 160 tires and NASCAR Craftsman Truck teams will get 120 tires.

Qualifying procedures: In all three national series, teams that are not locked into the starting field will qualify together as a group at the end of their respective qualifying sessions.

Engines: A new engine combination package introduced in the NASCAR Nationwide and NASCAR Camping World Truck Series will allow for cost-saving opportunities for teams.  Modifications reduce RPMs and horsepower, which will help engines and pieces to last longer. In turn, teams will have the opportunity to run multiple races using the same engine components.
