Who will be the Challenger Champ?

The pilots that can be crowned in Indianapolis

The Challengers ready for battle

It's not just the Master Class competition that's coming to a climax this weekend at the Holy Grail of Motorsport – the Indianapolis Motor Speedway.

Six pilots are flying here to make the most of the season, but only three have a chance of becoming the Challenger Cup Champion. Can Florian Bergér make it two wins in a row? Will the most successful pilot in the Challenger Cup, Daniel Ryfa, get his reward or will Luke Czepiela become the first Polish pilot to win. Here's who's flying and how their season could finish...

Florian Bergér
Current points: 36
Current position: 1st
Bergér is currently leading the standings with 36 points and is guaranteed the Challenger Cup with a win here in Indianapolis. And depending on the results of his opponents, the German could end up with the cup if he finished the race in second, third, fourth, fifth or even at the very bottom in sixth. But a last-place finish isn't likely for this defending Challenger Cup winner. If he does pull off a repeat Challenger title, he'll become the first pilot in history to do so!

Daniel Ryfa
Current points: 34
Current position: 2nd
Just two points behind his good friend Bergér with 34 points, Daniel Ryfa is one of the most consistent pilots in the annals of the Challenger Class. He has been among the top three in the overall points every year since he was an inaugural member of the Challenger Class in 2014 and is on the podium in 80% of his races! The Stockholm native is hungry to finally clasp the Challenger Cup and he will do so if he wins the race at "The Brickyard." He can also take the trophy if he finishes second, third or fourth, hinging on the results of Bergér and Luke Czepiela.

Luke Czepiela
Current points: 30
Current position: 3rd
Having accumulated race results including a win, one second and two thirds so far in 2017, Czepiela holds 30 points and is looking for his first season finish in the top three. An Indy win by itself won't guarantee him the cup, but with the right results from Bergér and Ryfa, Czepiela can still take home the trophy if he finishes first or second. The pilot from Poznan has excelled in Indianapolis before, achieving his career-first race win during last year's stop at the speedway.

Kevin Coleman
Current points: 26
Current position: 4th
The American hero can't win the Challenger Class, but with a win and other results going his way he can push his way up to second in the overall standing. It will be a step up for the pilot, in only his second year in the Challenger Class, last year he finished third.

Melanie Astles
Current points: 18
Current Position: 5th
Astles will not be able to get on the overall podium this season, but she will want to end the season on a high note. Last year Astles collected her best ever finish in the Challenger Class with a second place. She'll want to go one better this year and claim the first win of her Red Bull Air Race career.

Ben Murphy
Current Points: 16
Current position: 6th
Murphy is another pilot looking to end his season on a high. He has flown consistent and quick this year. He's topped sessions, but has been unable to convert those early quick times in to race wins. However, the British pilot will be hoping to go out strong in the 2017 season with a high finish.
