Honestly, if you were watching the final hour of the 73rd Mobil 1 Twelve Hours of Sebring, your heart rate probably hasn't settled yet. The bumps at Sebring International Raceway don't care about your "perfect season" or your manufacturer's legacy. They just want to break your suspension.
But for Porsche Penske Motorsport, the 2025 sebring 12 hours results proved that momentum is a hell of a drug. After their massive win at the Rolex 24 at Daytona back in January, the No. 7 Porsche 963 crew rolled into Florida with a target on their backs. They didn't just survive the target; they blew the doors off the competition in a 1-2 finish that felt like a statement of intent for the rest of the IMSA season.
How the No. 7 Porsche 963 Stole the Show
The record books will show Felipe Nasr, Nick Tandy, and Laurens Vanthoor as the winners, but that doesn't tell half the story. The race was a chess match played at 180 mph. For the first eight hours, it felt like the No. 31 Whelen Cadillac V-Series.R had the field covered. Pipo Derani and Jack Aitken were flying, and it looked like Cadillac would defend their turf.
Then the sun went down.
Sebring changes when the track temp drops. The Porsche 963, which struggled a bit in the midday Florida heat, suddenly found its legs. Nick Tandy, who is basically a wizard in low-grip conditions, pulled off a move on the back straight that left the Cadillac team scratching their heads. He used a group of slower GTD cars like a pick-and-roll in basketball, diving inside and never looking back.
- Winner: No. 7 Porsche Penske Motorsport (Nasr/Tandy/Vanthoor)
- Gap: 2.239 seconds over the sister No. 6 car
- Total Laps: 353
Nick Tandy actually made history here. With this win, he’s now one of only ten drivers to ever win the "Triple Crown of Endurance"—overall wins at Daytona, Le Mans, and Sebring. That’s elite company. We're talking A.J. Foyt and Hurley Haywood levels of legendary.

Chaos in the Classes: LMP2 and the GTD Bloodbath
If the GTP finish was a tactical masterclass, the LMP2 and GTD finishes were more like a bar fight. The sebring 12 hours results in the lower classes were decided by mistakes and "rubbing is racing" moments.
In LMP2, the No. 43 Inter Europol Competition Oreca 07 took the win, but they really had to sweat for it. They weren't even the fastest car for most of the day. However, the leading CrowdStrike car got tangled up with a GTD straggler with less than 20 minutes to go. Tom Dillmann just kept his nose clean and inherited the top step. Sometimes, being smart is better than being fast.
The GTD Pro finish was even more dramatic. AO Racing—everyone's favorite "Rexy" Porsche—finally got their breakthrough endurance win. Laurin Heinrich drove the wheels off that 911 GT3 R, holding off a charging pair of BMW M4s from Paul Miller Racing.
Final Class Winners at a Glance
- GTP: No. 7 Porsche Penske Motorsport
- LMP2: No. 43 Inter Europol Competition
- GTD PRO: No. 77 AO Racing (Porsche)
- GTD: No. 57 Winward Racing (Mercedes-AMG)
Winward Racing’s victory in the standard GTD class was wild. Philip Ellis basically used a "bump-and-run" on the No. 12 Lexus in the closing laps. It was aggressive. Kinda questionable? Maybe. But the stewards let them race, and Mercedes-AMG took home the hardware.
Why the 2025 Race Was Different
Most people focus on the winners, but the real story was the reliability of the new hybrid systems. We didn't see the mass-failures of 2023 or 2024. The Acura ARX-06 from Meyer Shank Racing finished third, proving that they've solved their long-run gremlins.
Even the Cadillac teams, while disappointed with a 4th place finish, showed they have the pace to win anywhere. The gap between the top five cars after 12 hours of literal concrete-pounding was less than 20 seconds. That is insane. It's basically a 12-hour sprint race.
The bumps at Sebring are legendary for a reason. They call it "Respect the Bumps," and this year, the track took its toll on the Lamborghini SC63, which had to retire early with floor damage. It’s a reminder that no matter how much money you spend on aero, the Florida pavement always gets its say.
The Aftermath and What's Next
So, where does this leave the championship? Porsche is currently running away with it. They’ve won the "36 Hours of Florida" (Daytona + Sebring), which is a feat no one has managed since 2017.
If you're a fan of Cadillac or BMW, don't panic yet. The season is long, and we’re heading to shorter "sprint" tracks where the BoP (Balance of Performance) might shift. But right now, the sebring 12 hours results show a Penske team that is firing on all cylinders.

Actionable Takeaways for Racing Fans
- Watch the Replays: If you missed the last 45 minutes, find the IMSA TV highlights. The restart after the final yellow was pure chaos.
- Track the Standings: Porsche now has a massive lead in the Michelin Endurance Cup. Every point matters heading into Watkins Glen.
- Technical Note: Keep an eye on the Porsche 963’s tire degradation. They seem to have a massive advantage in the "cooling track" phases of these races.
The road to the championship now moves away from the endurance classics and into the meat of the summer schedule. If anyone wants to stop the Porsche juggernaut, they'd better find some speed before Long Beach.
To keep your finger on the pulse of the season, make sure to monitor the official IMSA timing results for sector-by-sector breakdowns, as the raw pace of the Acura might actually be higher than the Porsche on smoother surfaces.
