Using INDYCAR’s advanced statistics and data, we’ve developed a weighted formula to rate the NTT IndyCar Series drivers after each race this season. Welcome to the Power Rankings – but that doesn’t necessarily mean that Will Power is always No. 1. 

How does it work? We look beyond the results of the event, also factoring in qualifying results, on-track passes, on-track position passes and average running position throughout the race to come up with each driver’s unique rating.

The rankings are based on the four most recent races. The most recent race (Bommarito Automotive Group) is weighted the most in the rating and the oldest race (Iowa 300) the least.

So, following the race at World Wide Technology Raceway and heading to Portland International Raceway, here’s a look at the top NTT IndyCar Series drivers:

Who’s No. 1:

Simon Pagenaud – Sometimes consistency is key and that’s what Simon Pagenaud has been since his win in the Indianapolis 500. The Team Penske driver continues to finish in the top five and moved into second in the championship. It also keeps the Frenchman No. 1 this week.

On the Rise

Santino Ferrucci – Another fourth-place finish for the rookie, who took the lead in the Rookie of the Year standings. If his teammate doesn’t crash after his final pit stop, he could have scored his first win.

Looking to Bounce Back

Alexander Rossi – After leading nearly every lap at Road America in June, Rossi has gone five races without leading a lap. Strategy didn’t fall his way at World Wide Technology Raceway, but he’ll need to bounce back in a big way to keep his title hopes alive.

The Top 10

1. Pagenaud (Last Rating: 1) – See above.
2. Ferrucci (Last Rating: 5) – See above.
3. Will Power (Last Rating: 3) – Crashed out early at World Wide Technology Raceway, but his form entering the weekend keeps Power near the top of the rankings.
4. Josef Newgarden (Last Rating: 4) – Won the pole and ran up front to maintain his series points lead. Only a spin late in the race that dropped him down the order kept him from being ranked higher.
5. Scott Dixon (Last Rating: 2) – Dixon’s run of four-straight top-two finishes came to a sudden end at WWT Raceway as debris damaged his radiator.
6. Alexander Rossi (Last Rating: 7) – See above
7. Tony Kanaan (Last Rating: Unranked) – Indy car racing’s Ironman shows he still has something left in the tank. Third at WWT Raceway was his first visit to the podium in almost two seasons.
8. Ed Carpenter (Last Rating: Unranked) – Carpenter wanted to end his season on a high note, and nearly did. Another lap and he may have won the Bommarito Automotive Group 500.
9. Conor Daly (Last Rating: Unranked) – Daly notched Carlin’s best finish of the season. Could a full-time ride with the team be in cards?
10. Colton Herta (Last Rating: Unranked) – There are a lot of ups and downs as an NTT IndyCar Series rookie. It looks like Herta is on the rise again.

Dropped out: Sebastien Bourdais (6), Graham Rahal (8), Spencer Pigot (9), Felix Rosenqvist (10).
