In 2011, NASCAR introduced an exciting new development in its championship points system, the Chase for the NASCAR Sprint Cup. In addition to the traditional top 10 drivers, the field of 12 contenders now includes two “wild cards,” among drivers who score the most wins outside the top 10. This has created a new level of excitement and suspense in determining the finalists for the premier series' championship.
Also in 2011, NASCAR introduced Sunoco Green E15 racing fuel in all three of its national series. This 15 percent gasoline/ethanol blend is the most significant development yet in the sport’s commitment to environmental responsibility — a commitment that has made NASCAR the No. 1 recycler among all major sports and a leader in promoting cleaner air and solar power.
