Graham Rahal moves up in INDYCAR's power rankings.

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 – and it doesn’t necessarily mean that Will Power will always be included.

How does it work? We look at more than just 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 rating.

The rankings are based on the four most recent races. The most recent race (REV Group Grand Prix presented by AMR) is weighted the most in the rating and the oldest race (Chevrolet Detroit Grand Prix Race 1) the least.

So, following Texas and heading to Road America, here’s a look at the top NTT IndyCar Series drivers:

Still the One

Alexander Rossi – The Andretti Autosport standout is riding a hot streak of five straight top-five finishes and remains solidly at the top of these Power Ratings for the third week in a row. Dominating the day at Road America will do that.

On the Rise

Graham Rahal – The same 10 drivers that have made up the top 10 after the last two races make up this week’s top 10 as well. Rahal rises to his highest ranking of the season after a solid fourth-place finish at Road America.

Looking to Bounce Back

Santino Ferrucci – After being ranked a season-high third last week, the rookie’s four-stop strategy at Road America failed to pay off. He tumbles to 10th after his worst finish in the last month.

The Top 10

  1. Rossi (Last Rating: 1) – See above
  2. Josef Newgarden (Last Rating: 3) – Third at Road America helps Newgarden maintain his points lead. He’s also cutting into Rossi’s top spot in the rankings.
  3. Will Power (Last Rating: 5) – The Road America runner-up moves up two spots in the rankings.
  4. Graham Rahal (Last Rating: 6) – See above
  5. Hunter-Reay (Last Rating: 2) – Hunter-Reay’s rise up the ranking plateaus with an 11th-place finish. Allowing three drivers with better weeks to pass.
  6. Scott Dixon (Last Rating: 10) – Get spun on the opening lap and still finish in the top five? Dixon may say it’s luck, but we’re here to say it’s more than that. He’s good too.
  7. Simon Pagenaud (Last Rating: 7) – Pagenaud stays seventh in the ranking after finishing ninth at Road America.
  8. Marcus Ericsson (Last Racing: 5) – The most consistent rookie of late is Ericsson, whose streak of top 10’s ended with a 13th.
  9. Takuma Sato (Last Rating: 9) – Same spot this week for Rahal Letterman Lanigan Racing’s Sato, who recovered from getting bounced off the track to finish 10th.
  10. Ferrucci (Last Rating: 3) – See above

Dropped out: No one
