Our Breakdown of Championship Scenarios Across the WeatherTech Championship, Michelin Endurance Cup, Michelin Pilot Challenge and VP Racing SportsCar Challenge
By Tony DiZinno
DAYTONA BEACH, Fla. – If you’re looking for drama, next week’s IMSA action at Michelin Raceway Road Atlanta is the place to be.
On its own, Saturday’s 10-hour Motul Petit Le Mans is one of the crown jewels in the world of sports car endurance racing. A victory in that race for any of the 54 teams competing across the four classes is a career-defining achievement.
But it means even more to a bevy of drivers, teams and manufacturers who find themselves in contention for not only Motul Petit Le Mans glory, but season-long championships in both the IMSA WeatherTech SportsCar Championship and the IMSA Michelin Endurance Cup.
The 29th Motul Petit Le Mans, airs live, Saturday, October 3 with the first three hours live on network NBC starting at noon ET and subsequent hours on NBCSN from 3 p.m. ET. Flag-to-flag streaming coverage is available in the U.S. on Peacock and internationally on the IMSA YouTube Channel.
Within the WeatherTech Championship, the top two in Grand Touring Prototype (GTP), top four in Le Mans Prototype 2 (LMP2), top seven in Grand Touring Daytona Pro (GTD PRO) and top three in Grand Touring Daytona (GTD) have a mathematical shot of winning the title, based on the available point deltas that can be overcome in one race.
Three of the four class leads are separated by only four, six and 47 points – in most cases one, two or three spots in-race – setting up straight-up drama across the board.
The same can be said for Friday’s two-hour Fox Factory 120 and the 45 IMSA Michelin Pilot Challenge teams spread across two classes.
The Michelin Pilot Challenge Grand Sport (GS) class has the top three covered by just 40 points (four spots) and the top five in realistic contention.
Here’s a look ahead to how the IMSA championships look and can be won at Michelin Raceway Road Atlanta to cap off the 2026 IMSA season:
IMSA WeatherTech SportsCar Championship
WeatherTech Championship Points
LMP2 and GTD – Single-Point Margins, Incredible Fights
Let’s start with the two closest battles. LMP2 is only a four-point gap between first and second, and GTD is just six points.
Essentially, whichever of the No. 43 Inter Europol Competition ORECA LMP2 07 of Tom Dillmann and Jeremy Clarke and No. 04 CrowdStrike Racing by APR ORECA of Alex Quinn and George Kurtz finishes ahead should claim the LMP2 title. There’s just four points between the two cars, so the margin will change after Friday’s qualifying heading into Saturday’s race.
We say “should” here because both Daniel Goldburg in his No. 22 United Autosports USA ORECA and defending LMP2 champions PJ Hyett and Dane Cameron in their No. 99 AO Racing ORECA also remain mathematically alive at 101 and 108 points back, respectively. But either car needs to win or at worst finish second to have a chance, gain some qualifying points, and hope both the Nos. 43 and 04 cars hit trouble.
Shifting to GTD, this is also an easy-to-decipher title battle. Philip Ellis and Russell Ward in their No. 57 Winward Racing Mercedes-AMG GT3 hold a six-point lead over Patrick Gallagher and Robby Foley in their No. 96 Turner Motorsport BMW M4 GT3 EVO. Once qualifying wraps, that will determine if the gap grows or shrinks from six and sets up Saturday’s showdown.
Eduardo “Dudu” Barrichello in the No. 27 Heart of Racing Team Aston Martin Vantage GT3 Evo remains somewhat alive at 116 points back. In an anticipated 18-car class, there’s a maximum of 242 points that could be gained by a perfect 385-point weekend with a minimum of 143 points for a car that qualifies 18th (13 points) and finishes the race in 18th (130 points). There are scenarios where Barrichello can snatch the title back, but he’d likely need a win or podium finish and the top two in the standings to finish outside the top seven for a realistic shot. First to eighth in the race is covered by 120 points.
Mercedes-AMG leads Aston Martin by 94 and Ferrari by 110 points in the GTD Manufacturer Championship. With nine manufacturers racing and the maximum swing of 130 points between first placed 350 and ninth place 220, any of these three could win the title.
GTD PRO – Three Realistic and Four Outside Contenders
GTD PRO has two tiers of contenders among seven of nine full-season cars mathematically alive heading to Motul Petit Le Mans.
The top three realistic contenders include the championship leading No. 4 Corvette Racing by Pratt Miller Motorsports Corvette Z06 GT3.R of Nicky Catsburg and Tommy Milner up by 47 over the second-placed No. 1 Paul Miller Racing BMW M4 GT3 EVO of Neil Verhagen and Connor De Phillippi and 53 ahead of third-placed Andrea Caldarelli and Sandy Mitchell in the No. 9 Pfaff Motorsports Lamborghini Temerario GT3.
Before factoring in qualifying points, the No. 1 and No. 9 cars have to finish two or more likely, at least three spots in the race ahead of the No. 4 car to overtake the points deficit.
The remaining four mathematically eligible range from 124 to 179 points back, including the Nos. 65 and 64 Ford Racing Ford Mustang GT3s, No. 14 Vasser Sullivan Racing Lexus RC F GT3, No. 77 AO Racing Porsche 911 GT3 R (992).
In an anticipated 14-car class, there’s a maximum of 208 points that could be gained by a perfect 385-point weekend compared to a 14th-place qualifying (17 points) and race finish 14th (170 points). At 211 points behind entering the weekend, the defending champion No. 3 Corvette is just out of mathematical range to be able to overcome the delta.
But Chevrolet could still be celebrating at the end of the night, even if the No. 4 car doesn’t win the Driver Championship. Chevrolet leads Ford by 68 points in the Manufacturer Championship. With nine manufacturers racing and the maximum swing of 130 points between first placed 350 and ninth place 220, there’s room for this title to go to either brand.
GTP – Aitken Well-Positioned, but Heinrich Still Has a Shot
Jack Aitken, in his No. 31 Cadillac Whelen Cadillac V-Series.R, holds the largest lead among the four WeatherTech Championship classes with a 147-point gap to Laurin Heinrich, who moves back to the No. 7 Porsche Penske Motorsport Porsche 963 this race.
A finish of ninth or better will clinch the Driver Championship title for Aitken provided the No. 31 car qualifies and leaves the grid for Saturday’s race.
In an anticipated 11-car grid, the maximum to be gained is 165 points, with 385 points available to win (350) and score pole (35). The lowest points score in that scenario is banking 220 points for finishing 11th (200) and qualifying 11th (20).
Aitken’s minimum points possible would be 2,972, while Heinrich’s maximum available if he won the pole and the race is 2,990. Heinrich has a remote chance, but he must win and then add whatever qualifying points to that to give himself a shot. Even then, he’d still need Aitken to qualify poorly and finish 10th or worse.
The No. 31 Cadillac Whelen entry has a 271-point lead on the No. 93 Acura Meyer Shank Racing with Curb Agajanian Acura ARX-06 in the Team Championship. Cadillac leads Porsche by 136 points in the Manufacturer Championship. Provided the No. 31 Cadillac leaves the grid, that will wrap the Team title and so long as the No. 31 or any Cadillac leaves the grid, that will secure the Manufacturer Championship.
Jim Trueman Award and Bob Akin Award
Jim Trueman Award and Bob Akin Award Points
The LMP2 Bronze-rated champion – Clarke, Kurtz, Goldburg or Hyett – will also win the Jim Trueman Award, as the top-scoring Bronze-rated driver in LMP2, with an IMSA-awarded invitation to the 2027 24 Hours of Le Mans.
In GTD, the Bob Akin Award is a two-driver battle between Orey Fidani (No. 13 13 Autosport Corvette Z06 GT3.R) and Brendan Iribe (No. 70 Inception Racing Ferrari 296 GT3 EVO). Fidani leads Iribe by 30 points. Iribe needs to finish at least two spots ahead of Fidani among Bronze-rated entries in GTD to overcome that gap. There are at least six cars with Bronze-rated drivers entered in class (Nos. 13, 16, 44, 66, 70 and 912).
IMSA Michelin Endurance Cup
IMSA Michelin Endurance Cup Points
The championship battle is tight here too, as two classes have single-point gaps between first and second: LMP2 and GTD. Just like their full-season championships.
CrowdStrike Racing by APR (Kurtz, Quinn and Toby Sowery) scored nine of a possible 10 points at Road America to move from two points behind to one point ahead of AO Racing (Hyett, Cameron and Jonny Edgar) in the LMP2 Michelin Endurance Cup standings (39-38).
As in LMP2, the GTD battle in the Michelin Endurance Cup is separated by only one point. Af Corse USA’s Antonio Fuoco and Simon Mann hold a one-point margin with their No. 21 Ferrari 296 GT3 EVO over the No. 27 Heart of Racing Team Aston Martin Vantage GT3 Evo trio of Barrichello, Tom Gamble and Zacharie Robichon. Three other cars – Winward’s No. 57 Mercedes-AMG, four back and the No. 34 Conquest Racing Ferrari 296 GT3 EVO and No. 120 Wright Motorsports Porsche 911 GT3 R (992) – both six back, may take some strategic chances.
In GTP, Felipe Nasr, Julien Andlauer and Laurin Heinrich have taken different paths and two different Porsche 963 entries to tie on 46 points through four Michelin Endurance Cup rounds. The trio reunites at Michelin Raceway in the No. 7 Porsche Penske Motorsport Porsche 963 for the first time since the Mobil 1 Twelve Hours of Sebring – which they won after also winning the Rolex 24 At Daytona.
Despite a tough Road America round, Paul Miller Racing still holds a solid lead in GTD PRO with its No. 1 BMW of Verhagen and De Phillippi. The duo is six points ahead of the No. 4 Corvette pair of Milner and Catsburg (38-32) leaving Road America. AO Racing’s Harry King and Nick Tandy sit third, seven points back, in their No. 77 Porsche 911 GT3 R (992). Either No. 4 or 77 car would need to score big to overcome that deficit.
IMSA Michelin Pilot Challenge
IMSA Michelin Pilot Challenge Points
Grand Sport (GS)
First-time Grand Sport (GS) championship leaders Austin Krainz and Stevan McAleer in the No. 27 AutoTechnic Racing BMW M4 GT4 EVO come to the 2026 Fox Factory 120 with a lead of 30 points, the fifth different team to lead the GS standings in 2026. They lead the No. 95 Turner Motorsport BMW of Dillon Machavern and Luca Mars by 30 points and Robert Noaker in the No. 13 McCumbee McAleer Racing Ford Mustang GT4 by 40.
Fourth-placed Michael Cooper and Moisey Uretsky (120 back, No. 44 Ibiza Farm Motorsport McLaren Artura GT4) and fifth-placed Bryce Ward (130 back, No. 57 Winward Mercedes-AMG) are in with a mathematical shot. Cooper and Uretsky won both at Indianapolis last race and Michelin Raceway last year. Wild point swings can occur with up to a maximum 340-point swing between first (350 points) and 30th (10).
Ted Giovanis (No. 64 TeamTGM Ford Mustang GT4) holds a 20-point lead on Dan Ammann and Owen Trinkler (No. 91 VRC Motorsports Group LLC Porsche 718 GT4 RS CS) in the GS Bronze Cup standings. Whichever car wins the Bronze Cup race also wins the title.
Touring Car (TCR)
Touring Car (TCR) sees Mason Filippi and Bryson Morris in their No. 33 Bryan Herta Autosport with Curb Agajanian Hyundai Elantra N TCR leading with a 200-point margin over teammates Denis Dupont and Preston Brown in the similar No. 76 Herta Hyundai. Provided Filippi and Morris start the season finale, they’ll score at least last-place points and have enough in hand to wrap the title, which would extend Herta and Hyundai’s run of title form where both team and manufacturer have won six TCR titles in the last seven years.
IMSA VP Racing SportsCar Challenge
IMSA VP Racing SportsCar Challenge Points
Both Oscar Tunjo (No. 1 Gebhardt Intralogistics Motorsports Duqueine D09) and Westin Workman (No. 8 RAFA Racing Toyota GR Supra GT4 EVO2) can clinch the Le Mans Prototype 3 (LMP3) and Grand Sport X (GSX) titles by starting Race 1 of 2 Thursday at Michelin Raceway. Tunjo’s in position to wrap both the overall and Sprint LMP3 titles.
Bronze Cup battles in both classes are tight though. Travis Hill (No. 2 Shopify Racing Ligier JS P325) and Brian Thienes (No. 77 Forte Racing Ligier) are tied in P3, while Jon Brel (No. 81 Kingpin Racing Toyota) leads Rafael Martinez (No. 68 RAFA Racing Toyota) by 110 points in GSX.
