Bobby Allison dominates the Winston Western 500 at Riverside, starting from pole and leading 173 laps of 191 en route to Victory Lane. This would be the first of three victories that year for the Matador. Being the opening event of 1975, the newly implemented points system began with this race. The points would now be awarded based on a drivers finishing position, being split into three separate tiers. The winner is awarded 175 points, second 170, third 165… and so forth on down to sixth place. Seventh place would garner 146 points, decreasing by 4 down to eleventh. Twelfth would see 127 points given, continuing to decrease by 3 down to last place. Five bonus points are also awarded for leading a lap, and five for leading the most laps. NASCAR would continue to use this system unchanged until 2004, when the Chase format was adopted.
