The Final Hours; Championship Outlooks; Michelin Endurance Cup Finale
By David Phillips
DAYTONA BEACH, Fla. – The long and winding road that is the 2026 IMSA WeatherTech SportsCar Championship reaches its final destination this weekend with the Motul Petit Le Mans at Michelin Raceway Road Atlanta.
With championships to be decided across the board and the usual fierce, unpredictable and entertaining action anticipated, we’ll look ahead to the key items to watch for this week.
The Final Hours
WeatherTech Championship racing intensifies when all four classes – Grand Touring Prototype (GTP), Le Mans Prototype 2 (LMP2), Grand Touring Daytona Pro (GTD PRO) and Grand Touring Daytona (GTD) – are present. But the final hours at Michelin Raceway are particularly renowned for their ferocity. And justifiably so.
With both the championship and race outcomes on the line, many drivers often go for broke if there’s nothing to lose. Others may take conservative approaches to protect leads. Michelin Raceway’s 12-turn, 2.54-mile circuit is chock full of blind corners and dramatic elevation changes while largely bereft of artificial lighting.
It may be a 10-hour race, but the last hour drama recipe is turned up to 11.
“We’ve seen for many, many years now that the racing is very exciting at the end of Petit,” says Tommy Milner, the GTD PRO championship leader with Nicky Catsburg aboard their No. 4 Corvette Racing by Pratt Miller Motorsports Corvette Z06 GT3.R.
“Atlanta is a very dark racetrack, so with all the elevation changes you have lots of areas where you are driving what feels like blind and just kind of going off of muscle memory. The track itself is difficult, and then obviously you throw in a big sports car race at the end of the year, the last race of a championship, and everybody is driving absolutely at the limit of themselves and the car’s capabilities.”
With the natural different performance dynamics across the prototype and GT cars, all drivers and spotters need to be on their toes. Additionally, optimizing setups for the cooler evening conditions is important after surviving what is often the hottest part of the day in the afternoon.
“You need to be quick in the night, which often requires a different car setup,” says Laurin Heinrich, who rejoins Felipe Nasr and Julien Andlauer in the No. 7 Porsche Penske Motorsport Porsche 963 this weekend.
“The interesting dynamic is that you have people still fighting for championships, and then you have people who are basically out of the championship fight just going for that single big endurance win, which is quite prestigious. So, they want it really badly. So, they have different mindsets, different approaches, and different goals about racing each other, basically in the last two-three hours.”
Championship Outlooks
It’s easier to count the championships that are almost wrapped than the ones that aren’t. Case in point in GTP, where only a cataclysmic weekend could collapse Jack Aitken’s clinch hopes in his No. 31 Cadillac Whelen Cadillac V-Series.R. But Heinrich, 147 points back entering the weekend in a year where he didn’t expect to race more than three times, still has a chance so long as he stays within 150 points leaving qualifying Friday.
Heinrich needs to win regardless; Aitken, who won this race last year with Earl Bamber and Frederik Vesti, remains focused.
“You can always argue to play it a bit safer when you have a lead in the championship,” Aitken says. “But it’s also dangerous to start changing your methods and to change the way that you approach things, because when you’re in a groove and when things are working well, you want to keep it as similar as possible. So we want to keep doing what we’re doing and the way we’re doing it because it works well for us and change as little as possible. And it’s also more fun to race that way. I think it’s more ambitious. It’s as simple as that from our point of view.”
What’s great about the other three class dynamic is that the combined lead margin in LMP2 (4 points), GTD (6) and GTD PRO (47) is just 57 points.
“With the position we’re in for the championship, we have got to attack, we have got to go forward,” says Alex Quinn, who shares the No. 04 CrowdStrike Racing by APR ORECA LMP2 07 with George Kurtz and enters four points behind Inter Europol Competition’s pair of Tom Dillmann and Jeremy Clarke in the No. 43 ORECA in LMP2.
“Our main aim is just to beat Inter Europol. But at the same time, there’s gonna be the rest of the field going too, and their aim is to win the race and to get good results.”
The Turner Motorsport team is trying to topple Winward Racing in GTD. Robby Foley and Patrick Gallagher in their No. 96 BMW M4 GT3 EVO enter six points back of Russell Ward and Philip Ellis in their No. 57 Mercedes-AMG GT3.
“It’s just another race,” says Foley. “But in the end, we’re definitely going to be focused on what the 57 car is doing in qualifying. In the end, it could come down to one position.”
Ward added, “We’ll start with qualifying and see if we can extend that points lead to a position greater than just being one car in front. And if we can do that that’ll give a little bit of a little bit of a buffer room for us. We’re just going to go in and race the racetrack and see where it comes out. Looking forward to it, and it’s going to be a battle down to the end.”
Another BMW is in chase mode in GTD PRO: the No. 1 Paul Miller Racing BMW M4 GT3 EVO of Connor De Phillippi and Neil Verhagen. They’re 47 points back of Milner and Catsburg.
“We’re going in as the hunter this weekend instead of the hunted,” says De Phillippi. “So that’ll be a refreshing position to be in, in terms of how we race. It’s kind of ‘go win’ and that’s really the only option.”
IMSA Michelin Endurance Cup Finale
While GTP and LMP2 maintain their same full-season grids of 11 cars, five additional GTD PRO and GTD cars apiece from the usual nine and 13 expand to 14 and 18, respectively, for the fifth and final IMSA Michelin Endurance Cup round of the year.
A fun nugget for this endurance round: 74 drivers at this year’s Motul Petit Le Mans also raced at the 24 Hours of Le Mans, which had a field of 186 drivers, so about 40 percent of the field. Motul Petit Le Mans is a 10-hour race, 40 percent of the 24-hour race.
And percentages make all the difference within the IMSA Michelin Endurance Cup, too. Keeping with the 40 percent number, the first points are awarded at Hour 4, with the next batch at Hour 8 and the final at Hour 10. Teams often strategize their way to the front for these specific markers, even if it may look unorthodox.
Porsche Penske Motorsport’s No. 7 car has this Team Championship wrapped, and Porsche can wrap the Manufacturer Championship with any second-place finish at any interval. The drivers are tied, owing to Heinrich’s quirky “magical mystery tour” season where the young German has been in three different Porsches – both the PPM No. 7 and No. 6 and JDC-Miller MotorSports No. 5 – this season (and the last three races).
In LMP2, the No. 04 trio of Quinn, Kurtz and Toby Sowery leads AO Racing’s No. 99 ORECA of PJ Hyett, Dane Cameron and Jonny Edgar by a single point.
That’s the same gap in GTD with Antonio Fuoco and Simon Mann’s No. 21 Af Corse USA Ferrari 296 GT3 EVO one point clear of the trio of Eduardo “Dudu” Barrichello, Tom Gamble and Zacharie Robichon in their No. 27 Heart of Racing Team Aston Martin Vantage GT3 Evo. Ferrari leads Aston Martin in GTD by two points (40-38).
In GTD PRO, PMR’s De Phillippi and Verhagen have a six-point lead in these standings over Milner and Catsburg, with AO Racing’s Nick Tandy and Harry King seven back in their No. 77 Porsche 911 GT3 R (992). BMW (39 points) leads Porsche by three and Chevrolet by four here.
Thus are a host of championships on the line this weekend, along with the prestige of joining an illustrious list of Motul Petit Le Mans winners. Be sure to catch all the action starting at noon ET on NBC, with continuing coverage on NBCSN at 3 p.m. ET. The race streams on Peacock domestically with NBC’s crew and the IMSA YouTube channel internationally with IMSA Radio commentary.
