Indycar announced the following manufacturer championship points update following the Iowa Corn 300, which was held July 18 at Iowa Speedway:
Honda received a deduction of 100 manufacturer points for engines that did not attain their life cycle minimum. According to Rule 10.6.4.3 of the Verizon IndyCar Series rulebook, 20 manufacturer points are deducted for an engine that fails to reach its 2,500-mile life cycle. The Honda engines on the No. 5 Schmidt Peterson Motorsports, No. 15 Rahal Letterman Lanigan Racing, Nos. 26 and 28 Andretti Autosport and No. 98 BHA with Curb-Agajanian entries did not reach their life cycle minimum before being changed out after the Iowa Corn 300 race weekend.
Following the adjustment, Chevrolet has totaled 1,279 manufacturer points for the season and Honda has 911.
