Chevrolet earned 122 points and Honda 72 in the Verizon IndyCar Series’ season-opening Firestone Grand Prix of St. Petersburg under the first-year Manufacturers’ Championship scoring system.

The format mirrors points awarded to the top five drivers and entrants in each race when running one of the four assigned engines allotted for the season. Bonus points are awarded for earning the Verizon P1 Award, leading the most laps and all drivers/entrants leading at least one lap.

So how did they accumulate their respective totals? Breaking it down:

Double points to the top five finishers will be awarded for the three 500-mile races (Indianapolis Motor Speedway, Pocono Raceway, Auto Club Speedway). There is a separate Indianapolis 500 bonus points format for qualifications on May 17 and the Fast Nine Shootout on May 18:

Manufacturer points totals will be in flux throughout the 18-race season as they will receive a 10-point award for each of their 2.2-liter, twin-turbocharged V6 engines that reach the 2,500-mile change-out threshold set by INDYCAR for 2014. Conversely, 10 points will be deducted from the total for each time an engine is changed before it meets the mileage threshold or surpasses the mandated number of engines for the season.
