How to watch the 2025 Twelve Hours of Sebring on Peacock: Streaming info, start times and daily schedules

With extra motivation for one of its stars, Porsche Penske Motorsport will take aim at the Mobil 1 Twelve Hours of Sebring after dominating the IMSA WeatherTech SportsCar Championship season opener.
As the No. 7 963 won the Rolex 24 at Daytona for the second consecutive year, the victory was especially significant for Nick Tandy. The 40-year-old Brit became the first driver in history with overall wins in the Rolex 24, the 24 Hours of Le Mans and the 24-hour races at Nurburgring and Spa.
Tandy has three GT class victories at Sebring, but he has yet to win the overall in the prestigious endurance race in Central Florida that will hold its 73rd running Saturday (10 a.m. ET, streaming flag to flag on Peacock).
'There's high motivation, of course, but it's no more than any other year,' said Sebring, who will be teamed with co-drivers Felipe Nasr and Laurens Vanthoor on Porsche Penske Motorsport's No. 7. 'Sebring has been a good event for me. The last two years, we came close both times to being in a position to win at the end. The big races are fantastic to win, but at the end of the day, they score the same points as any other race. And you always go into each event with maximum motivation.
'It's just kind of when records build, then the individual races get talked about a little bit more, which is great. It's something that I've been thinking about the last couple of years trying to win overall. So yeah, it would be great obviously. I've got the overall win at Petit (Le Mans), so that would kind of complete the 'Big Six' as well.'
After winning the Grand Touring Prototype season championship last year, the team is seeking to become the first to start an IMSA season with consecutive overall victories since Wayne Taylor Racing in 2017.
Porsche Penske Motorsport managing director Jonathan Diuguid said the team tested several updates in a session last month and during the offseason.
'We had a good feeling with the car and a lot of our updates are intended to work on tracks like Sebring, so it gave the engineering and driver crews the opportunity to go through and evaluate that further,' Diuguid said. 'On the whole, we're quite happy with where we were in Sebring and looking forward to the race weekend.'

Mathieu Jaminet, part of the No. 6 963 driving lineup, said the car was improved from the past two seasons. 'Now looking forward to the race and hopefully bringing the same performance to the table,' Jaminet said.
Said Tandy: "(It) was probably the best Sebring test for sure that we've had as a team and with the car since I joined the program. Obviously, you expect every time we go out, we're learning. We expect to get better. So we won championships, yes, but you can never rest on your laurels, and there has been a lot of hard work. Sebring has not typically been the best track for the Porsche 963, which we've recognized.'
The bumpy track's rumbling and weathered surface has tended to favor Cadillac, which added the defending race winner to its lineup this year.
In a bruising battle, Louis Deletraz and Wayne Taylor Racing delivered the first Twelve Hours of Sebring victory for Acura last year before WTR moving back to Cadillac, its longtime partner, for 2025.

Deletraz and Jordan Taylor return in the No. 40 Cadillac V-Series.R with new co-driver Brendon Hartley among the 56 entries across four categories for the 12-hour race.
Sebring will mark the first GTP race for Aston Martin's new Valkyrie, which made its World Endurance Championship debut at Qatar two weeks ago. The Valkyrie is built to Le Mans Hypercar (LMH) specifications that are tailored to the WEC, and this will mark the first crossover for an LMH car competing against the LMDh prototypes of IMSA's top category.
The Valkyrie, which uses a naturally aspirated V12 engine vs. the hybrids of LMDh, will increase the GTP field to a record 13 cars and six manufacturers (Acura, BMW, Cadillac, Lamborghini and Porsche are the others) at Sebring.

NASCAR Insider Proposes Races in Canada and Europe after Mexico Success

Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Following NASCAR's first international points-paying Cup Series race beyond the borders of the USA in Mexico last weekend, former NASCAR driver, commentator, and analyst Kyle Petty has proposed that the sport must consider racing in Canada and Europe. The race in Mexico's Autódromo Hermanos Rodríguez saw a huge crowd turnout, prompting Petty to point out NASCAR fan bases in international locations. While Canada is one option, given the close proximity to America, he suggested a one-time race in Europe, especially after NASCAR pitched a custom Chevrolet Camaro ZL1 to compete in the 2023 24 Hours of Le Mans. Speaking to George Howson on Motorsport Reports, Petty said: "Obviously, if we're opening up Mexico, then I think we should take a look at Canada. I would like to see that. There are so many race fans. If you go to Michigan, Watkins Glen, you're right along the Canadian border. There's so many Canadian fans that come over. ... So I look at that and I say, Yeah, those are no-brainers to me. Shane Van Gisbergen, driver of the #88 Safety Culture Chevrolet, celebrates with a burnout after winning the NASCAR Cup Series Viva Mexico 250 at Autodromo Hermanos Rodriguez on June 15, 2025 in Mexico City, Mexico. Shane Van Gisbergen, driver of the #88 Safety Culture Chevrolet, celebrates with a burnout after winning the NASCAR Cup Series Viva Mexico 250 at Autodromo Hermanos Rodriguez on June 15, 2025 in Mexico City, Mexico."I would love to see us land somewhere in Europe, at least once. I've been going to Goodwood [in England], places like that. There are so many NASCAR fans, so many stock car fans, and it's just a totally different form of racing than Formula One or sports cars or Le Mans and that type of racing. "It's just a totally different form. It's not better, it's not worse, it's just different, that's just the way it is. I think it would be interesting to see the type of crowd that we could draw over there on an oval, or on a road course, because we have opened ourselves up with this car to be in a road course-type series. I know it's never gonna go to full road courses, but there will be a lot more of them that add on." Howson added: "We saw in Le Mans a few years ago [in 2023], these cars can run around actual world endurance championship circuits, so there's no reason why we can't say I'd love to see NASCAR in Europe. That'd be awesome." Speaking of road courses, while Petty acknowledged that more would be added to the NASCAR calendar in the future, his father, Richard Petty, famous for winning seven Cup Series championships, has dismissed road courses. While addressing how Shane van Gisbergen's victory in Mexico got him a spot in the playoffs, despite being 30th in the standings, Richard targeted the sport's 'if you win, you're in' policy and road courses. Newsweek Sports reported his comments: "The way they got this thing fixed, where if you win, you're in. That can't be right. You got somebody that's 30th in points that's going to make the playoffs. Hey man, what happened to the guy that 15th, or 16th, or 18th (that's) been running good (and) finished good everywhere? "You're making a championship situation by winning a road course, which is not really NASCAR to begin with. From that standpoint, I think they're going to have to jockey around and change some of this kind of stuff."

2025 IMSA Watkins Glen starting lineup: Acura takes second consecutive pole with No. 93

With a new face behind the wheel, Acura Meyer Shank Racing captured its second consecutive pole position in the IMSA WeatherTech SportsCar Championship series with a record-setting performance at Watkins Glen International. Renger van der Zande turned a lap of 1 minute, 31.558 seconds in the No. 93 ARX-06, setting a new mark on the 11-turn, 3.4-mile road course in the Grand Touring Prototype category. Three weeks ago on the streets of Detroit, van der Zande took the checkered flag in the Acura MSR No. 93 after teammate Nick Yelloly had qualified on the pole position. 'Winning Detroit always helps take the weight off the shoulders of the whole team, the program,' van der Zande told NBC Sports' Dave Burns on Peacock after his first pole position since the 2018 Rolex 24 at Daytona. 'The Porsches are way ahead in the championship, and it's hard to beat them over the championship, so let's win some races, and this is a good start. We have a strong car in high-speed stuff like this. That was a very clean lap, and I was enjoying it a lot.' Nate Ryan, Yelloly, who won in the LMP2 category of the 24 Hours of Le Mans last week, and van der Zande will be joined by Kakunoshin 'Kaku' Ohta in Sunday's third endurance race of the IMSA season. Jack Aitken qualified second (1:31.845) in the No. 31 Cadillac, followed by Colin Braun (1:32.167) in Meyer Shank Racing's No. 60 Acura ARX-06. It was a disappointing showing for Porsche Penske Motorsport, which won the first four races of the season. Mathieu Jaminet qualified eighth (1:33.323) in the No. 6 963, and Felipe Nasr (1:33.533) will start 10th in the No. 963 that leads the championship standings. Here are the pole-sitters in other categories for Sunday's six-hour race, which will start shortly after noon ET on NBC and Peacock: LMP2: PJ Hyett, No. 99 AO Racing ORECA LMP2 07, 1:35.878 GTD Pro: Andrea Caldarelli, No. 9 Pfaff Motorsports Lamborghini Huracan GT3 EVO2, 1:44.595 GTD: Zacharie Robichon, No. 27 Heart of Racing Team Aston Martin Vantage GT3 Evo, 1:44.788 WATKINS GLEN QUALIFYING ROUNDUP Results Results by class Fastest lap by driver Fastest lap by driver after qualifying Fastest lap by driver and class after qualifying Best sector times Fastest lap sequence Time cards Weather report Track limits analysis PRACTICE RESULTS: Session I l Session II
