Only two post-event infractions have been issued by INDYCAR following the finale round of the 2015 Verizon IndyCar Series season which was held August 30 at Sonoma Raceway - and both stem from the controversial incident that took place on pit lane in the early stages of the race.

As race leaders Will Power and Josef Newgarden were leaving their pit boxes during their first stops of the race, Power's Penske teammate Simon Pagenaud was entering his own, which was located in front of Newgarden's. Newgarden went to leave, but was trapped by Pagenaud turning toward him to enter his box. Pagenaud sat motionless beside Newgarden before the young American driver in the No. 67 Chevrolet shot quickly through Pagenaud's pit box ahead of him to cut down on time lost to Will Power.

The two lone infractions

• The No. 22 Team Penske entry of Simon Pagenaud was fined $2,500 for violating Rule 7.9.17.1 (courtesy zone) and Rule 7.10.1.1 (lane usage).

• The No. 67 CFH Racing entry of Josef Newgarden was fined $500 for violating Rule 7.10.1.6 (contact with another car's pit equipment).

Final Manufacturer Championship update

Additionally, Honda received a deduction of 80 points in the Manufacturer Championship for engines that did not reach their life cycle during the GoPro Grand Prix of Sonoma weekend. According to Rule 10.6.4.3, 20 manufacturer points are deducted for an engine that fails to reach its 2,500-mile life cycle.

The Honda engine of the No. 15 Rahal Letterman Lanigan Racing car of Graham Rahal, the No. 26 Andretti Autosport car of Carlos Munoz and Jack Hawksworth's No. 41 A.J. Foyt Enterprises car all underwent engine changes during the finale weekend at Sonoma, costing Honda 20 points in the Manufacturer Championship each, totaling 60 deducted points. The remaining 20 points of the Japanese manufacturer's penalty for the weekend of 80 were issued because the wrong engine was fitted in the No. 41 entry.

Chevrolet won the Manufacturer Championship with 1,645 points with Honda finishing the season with 1,179 points.
