Petit Le Mans 2026 preview: Campbell's last Porsche race
Saturday at noon Eastern, 54 cars take the green flag at Michelin Raceway Road Atlanta for ten hours of Petit Le Mans, the last round of the 2026 IMSA WeatherTech SportsCar Championship. Out here that's a 9 a.m. start, which means the race ends after dark in Georgia while the sun is still dropping over the Pacific. Coffee on, laptop open, phone on the counter for the timing app.
There are titles to settle in every class, and one goodbye worth paying attention to. Matt Campbell drives the No. 6 Porsche 963 for the last time, closing out a decade with the factory before he moves to Ford's new World Endurance Championship hypercar program. Here is what is actually on the line, and what to watch for if you spend your weekdays thinking about how fast cars look on camera.
Matt Campbell's final race for Porsche
Campbell shares the No. 6 Porsche Penske Motorsport 963 with Laurens Vanthoor and Kevin Estre, which is about as strong a three-driver lineup as the paddock has. This is only his third IMSA start of the season. He ran the endurance opener at Daytona, where the car finished fourth, and Sebring, where it finished second.
In Porsche's own race preview, Campbell calls it the end of "10 wonderful years together." The relationship goes back further than the factory contract: Formula Ford, Porsche Sprint Challenge, a Carrera Cup Australia win, then the long climb to a works seat. Speedcafe's preview confirms that once the checkered flag falls, he turns his attention fully to Ford's Hypercar effort.
That Ford program is moving quickly. The unnamed LMDh car, a 5.4-liter V8, finished a two-day test at Silverstone this week, its first run at a WEC calendar venue and its first outing with headlights. Logan Sargeant, Nick Yelloly and Sebastian Priaulx did the driving; Monza is next in late October, with North American testing at the end of the year and a WEC debut set for 2027. So Saturday is the last time Campbell climbs into a Porsche in anger, and the next car he races will be a front-of-the-grid American V8.
Porsche has its own reason to want this one. Per the factory preview, the 963 has never won at Road Atlanta. Sending Campbell off with that first win would be a tidy way to close the book.
The GTP title fight: Aitken against the math
The headline championship is close to decided. Dailysportscar's points breakdown has Jack Aitken in the No. 31 Whelen Cadillac V-Series.R on 2,752 points. Laurin Heinrich in the No. 7 Porsche 963 sits second on 2,605, 147 points back. Aitken locks it up with a ninth-place finish or better in GTP. Heinrich needs to win and needs Aitken to have a bad day in the process.
Heinrich isn't pretending otherwise. In the Porsche preview he says he still has "an outside chance" and that giving up isn't an option. He shares the No. 7 with Julien Andlauer and Felipe Nasr, so if the Cadillac stumbles, the car will be there to take advantage.
Cadillac has effectively wrapped up the GTP manufacturers' title already. Porsche runs second there too. Three 963s are entered in total: the two Penske cars and the No. 5 JDC-Miller entry, where Nico Müller races at Road Atlanta for the first time.
Where the championships are still genuinely open
Some of the best racing on Saturday will happen further down the order.
LMP2: four points, two cars
The No. 43 Inter Europol Oreca of Jeremy Clarke and Tom Dillmann leads the No. 04 CrowdStrike by APR entry of George Kurtz and Alex Quinn by four points, 1,950 to 1,946. That's effectively a winner-takes-all race between the two, and the No. 43 holds the tiebreaker on wins.
GTD Pro: seven cars still alive
GTD Pro is the class to keep a second window open for. Tommy Milner and Nicky Catsburg lead in the No. 4 Corvette Z06 GT3.R with 2,729 points. Behind them:
- No. 1 Paul Miller Racing BMW M4 GT3 Evo, Connor De Phillippi and Neil Verhagen, 47 back
- No. 9 Pfaff Motorsports Lamborghini, Andrea Caldarelli and Sandy Mitchell, 53 back
- No. 65 Ford Mustang GT3, Christopher Mies and Frédéric Vervisch, 124 back
- No. 64 Ford Mustang GT3, Dennis Olsen and Ben Barker, 149 back
- No. 77 AO Racing Porsche 911 GT3 R, Nick Tandy and Harry King, 154 back
A win clinches it for the Corvette. If the No. 4 falls off the podium, the BMW and the Lamborghini are both in play. Pfaff also runs its last IMSA race this weekend, so the Lamborghini has some sentiment riding on it.
GTD: six points
The No. 57 Winward Racing Mercedes-AMG of Russell Ward and Philip Ellis leads the No. 96 Turner Motorsport BMW of Patrick Gallagher and Robby Foley by six points. Whichever of those two finishes ahead will almost certainly take the title.
How to watch Petit Le Mans from Southern California
Qualifying runs Friday afternoon, and the race is Saturday, October 3, from noon to roughly 10:30 p.m. Eastern. That's 9 a.m. to about 7:30 p.m. Pacific. IMSA's US broadcast partners list Peacock, USA Sports, IMSA.TV and YouTube for coverage.
If you only have time for part of it, take the last three hours. The race starts in daylight and finishes in full darkness. The run from dusk to the checkered flag is when tire choices, traffic and fatigue all land on the same lap, and when championships usually get decided.
What a 10-hour race teaches about shooting cars
We watch endurance racing as fans first, but it's also the best free lesson in automotive light you'll find on TV. A few things to look for on Saturday if you shoot:
- Dusk is the money window. Somewhere around the seventh hour, the broadcast cameras will catch prototypes with headlights on against a sky that still holds color. That twenty-minute stretch is the same light we chase on Palomar's South Grade, and the reason most of our rolling shoots are scheduled backwards from sunset.
- Watch the shutter on the pans. Trackside TV cameras run high shutter speeds to keep the image crisp, so the backgrounds look frozen. Compare that to the long, smeared backgrounds in still photography and you'll see why we drag the shutter on a chase. Our guide to shooting a rolling shot from the chase car covers the settings.
- Night racing is a lighting problem. Brake discs glowing through the wheel, LED signatures, pit-lane floodlights against black bodywork. All of it is easier to read than a static car parked under a streetlamp, and the same principles from our night shooting guide apply.
- Livery reads differently at speed. A busy race livery that looks chaotic in the paddock often turns into one clean stripe at 150 mph. Worth remembering the next time a client asks whether their wrap will photograph well.
The broadcast won't show you everything. It will show you a 963 coming off Turn 12 under lights, though, and that's worth studying.
Why the Campbell move matters beyond Georgia
Driver moves rarely change much for owners, but this one is a signal. Ford is putting experienced prototype drivers into a V8 hypercar aimed at Le Mans, McLaren is building its own next-generation hybrid, and the manufacturers who sell road cars in Southern California keep using endurance racing to justify them. The 911 GT3 R in GTD is the closest race car to anything you can park in a Rancho Santa Fe garage, and its road-going relatives turn up all over our portfolio.
Whoever wins on Saturday, Campbell's last lap in the No. 6 is worth staying up for.
