That, right there, is IMSA racing at its most brilliantly chaotic. Four hours into the 10-hour Motul Petit Le Mans at Michelin Raceway Road Atlanta, the skies decided to tear open and throw everything they had at the 54-car field. When a lightning strike forced a red flag that eventually led to a full-course yellow resumption shortly after 4:15 p.m. ET, none other than Colin Braun was sitting at the front of the pack.
Let us talk about how we got there, because the weather has completely shredded any sort of straightforward strategy. The race began with every single machine sliding around on wet weather Michelin tires as pre-race showers soaked the asphalt. But the track dried out in a hurry, sending the entire grid diving into the pits to swap for dry-weather slicks. That relative peace lasted for roughly two-plus hours before the heavens opened up yet again with six hours and 43 minutes remaining, triggering a frantic scramble as more than half the field bolted back to the pits for wets.
“Here in Georgia, rain is tough to predict; it could rain one minute, then be off the next,” Ryan Hardwick told IMSA Radio after his stint in his last full-time race aboard the No. 912 Manthey 1st Phorm Porsche 911 GT3 R (992). He speaks the truth, because the weather has turned Grand Touring Prototype (GTP) into an absolute warzone. Before the second downpour, the battle was raged primarily between the No. 24 BMW M Team WRT BMW M Hybrid V8 and the Nos. 60 and 93 Acura entries on slicks. But when the rain started, three brave cars—the sister No. 25 BMW, the No. 6 Porsche Penske Motorsport Porsche 963, and the No. 40 Cadillac Wayne Taylor Racing Cadillac V-Series.R—stayed out on slicks. Braun's wet-shod No. 60 Acura Meyer Shank Racing with Curb Agajanian Acura ARX-06 took full advantage, launching from fourth into the lead during a brief green flag interlude before two LMP2 cars spun at pit entrance to spark the sixth full-course caution.
Down in Le Mans Prototype 2 (LMP2), Misha Goikhberg played the ultimate spoiler in the No. 52 Bryan Herta Autosport with PR1/Mathiasen ORECA LMP2 07 against the championship contenders. With minimum drive time periods cleared, Jeremy Clarke handed the No. 43 Inter Europol Competition ORECA to Tom Dillmann, while George Kurtz passed the No. 04 CrowdStrike Racing by APR ORECA to Alex Quinn. Clarke, Kurtz, and Daniel Goldburg in the No. 22 United Autosports USA ORECA put on a stunning scrap for the podium right behind Goikhberg.
Over in Grand Touring Daytona Pro (GTD PRO), the three realistic title contenders all took turns at the very sharp end of the field. Tommy Milner had the No. 4 Corvette Racing by Pratt Miller Motorsports Corvette Z06 GT3.R leading the class at the four-hour mark, fighting hard alongside the No. 1 Paul Miller Racing BMW M4 GT3 EVO and the No. 9 Pfaff Motorsports Lamborghini Temerario GT3. Meanwhile, in Grand Touring Daytona (GTD), Albert Costa put the No. 34 Conquest Racing Ferrari 296 GT3 EVO out front while trouble found almost every single championship challenger.
Speaking of the championships, the math has already settled some scores. Jack Aitken secured enough points just by starting the race to lock up the GTP driver championship in the No. 31 Cadillac Whelen Cadillac V-Series.R, handing Cadillac Whelen the team crown and Cadillac the GTP manufacturer title. But the GTD battle is looking heavily tilted toward Philip Ellis and Russell Ward in their No. 57 Winward Racing Mercedes-AMG GT3 for a third straight year, especially since their rivals hit disaster. Robby Foley and Patrick Gallagher saw their second-placed No. 96 Turner Motorsport BMW M4 GT3 EVO retire due to a water pressure issue, while Eduardo “Dudu” Barrichello's No. 27 Heart of Racing Team Aston Martin Vantage GT3 Evo suffered electrical gremlins that kept it behind the wall before the green flag even dropped, finally returning more than an hour late.
In the IMSA Michelin Endurance Cup standings with the first segment complete, Porsche holds the upper hand in GTP. Over in LMP2, the No. 04 CrowdStrike and No. 99 AO Racing ORECAs are sitting in an unofficial tie for the season lead on 42 points. The No. 4 Corvette's class-leading points haul pulls it within three points of the No. 1 PMR BMW, and just a single point separates the No. 21 Af Corse USA Ferrari 296 GT3 EVO and the No. 27 Aston Martin in GTD. With six hours left to run, absolutely nothing is decided.
