INDYCAR has announced the following manufacturers' championship points adjustments following the Indianapolis 500 Open Test Day on May 3 at the Indianapolis Motor Speedway:

• Honda received a bonus of 30 engine manufacturer points for attaining the life cycle minimum for three of its engines. According to Rule 10.6.4.2 of the Verizon IndyCar Series rulebook, any engine that reaches a lifespan of 2,500 miles will receive 10 bonus for its manufacturer. Honda engines for the No. 15 Rahal Letterman Lanigan entry, No. 26 Andretti Autosport entry and No. 98 BHA with Curb Agajanian entry all reached at least 2,500 miles.

• Chevrolet received a points deduction of 20 points. According to Rule 10.6.4.3, 20 points will be deducted for an engine that fails to reach its life cycle. The engine in the No. 83 entry did not reach 2,500 miles before it was changed out.

• Chevrolet also had four of its entrants' engines - the Nos. 1 and 22 from Team Penske and Nos. 9 and 10 of Chip Ganassi Racing Teams - reach their 2,500-mile lifespans, but they will not receive manufacturer bonus points according to Rule 10.6.4.4, which states that an engine is no longer eligible for mileage lifespan points once it has undergone a non-minor repair approved by INDYCAR.

Following the adjustments, Honda has a total of 380 manufacturer points and Chevrolet 216.

Members may contest the imposition of penalties pursuant to the procedures and timelines detailed in the review and appeal procedures of the Verizon IndyCar Series rulebook.
