NBC Sports will preview the 2025 IMSA WeatherTech SportsCar Championship season finale, Motul Petit Le Mans, with a special one-hour show on Sunday, Oct. 5 at 3 p.m. ET on NBC and Peacock.

The network show will air the Sunday before Motul Petit Le Mans, which kicks off live on network NBC at noon ET on Saturday, Oct. 11.
Peacock will stream the full race flag-to-flag (in the U.S.) with additional streaming via IMSA.TV and IMSA’s Official YouTube channel (internationally).
The top-level, factory-supported production car-based class in American sports car racing has evolved through several names and technical specifications over the last 15 years. But there’s been one constant:

Corvette drivers Antonio Garcia and Alexander Sims will be fighting to win the GTD-Pro championship in this last IMSA race of 2025 season

Since the 45-year-old Spaniard joined Corvette Racing by Pratt Miller Motorsports in 2009, he has excelled in every iteration of the premier GT category, through half a dozen technical regulation changes and three generations of Corvettes.

Garcia won his first championship in the GT class of the American Le Mans Series in 2013 with co-driver Jan Magnussen, the final year before ALMS and IMSA’s TUDOR United SportsCar Championship merged to create the modern-day IMSA WeatherTech SportsCar Championship. Teamed with Magnussen from 2014-’19, Garcia won a pair of IMSA Grand Touring Le Mans (GTLM) titles for Corvette Racing in 2017 and ’18 and added two more teamed with Jordan Taylor in 2020 and ’21.

Garcia has collected a total of 31 IMSA race wins along with his quintet of championships, including five wins since the most recent GT category realignment that created the Grand Touring Daytona Pro (GTD PRO) class in 2022.
But whether with Taylor in ’22 and ’23 or his current co-driver Alexander Sims, Garcia has never achieved a GTD PRO championship.

That could change October 11 at Michelin Raceway Road Atlanta. Sims and Garcia and the No. 3 Corvette Z06 GT3.R will carry a slim 18-point advantage into the season-concluding Motul Petit Le Mans over Albert Costa, who has shared DragonSpeed’s No. 81 Ferrari 296 GT3 for the majority of the year with Giacomo Altoè and endurance driver Davide Rigon. Mike Rockenfeller and Sebastian Priaulx sit third, 169 points back in the No. 64 Ford Multimatic Motorsports Ford Mustang GT3, with an outside shot.

Given his record, it’s surprising that Garcia has not won a championship to date during the GTD PRO era. What’s even more remarkable is that while Corvette Racing owns eight victories at Motul Petit Le Mans, Garcia has never tasted the champagne in Georgia a measure of how challenging and unpredictable the 10-hour day-into-night endurance classic can be.

Sims and Garcia achieved their only win of the ’25 season at VIRginia International Raceway with an aggressive undercut pit stop strategy from the Corvette by Pratt Miller team that vaulted them to the front of the field.
At that point, they led Costa by 53 points, but the fellow-Spaniard cut the margin to 18 by finishing second ahead of the No. 3 Corvette in fourth at the most recent WeatherTech Championship race at Indianapolis.

“The last few races we’ve been always trying to cover different strategies coming from especially the No. 77 (the defending GTD PRO class champion AO Racing Porsche that lies fourth in this year’s standings) or the No. 81 (Costa),” Garcia said. “When people are probably not feeling very competitive or are not in contention at some point, that’s when they roll the dice and they kind of put everybody under the pressure.

“So, I think we really need to be very prepared on that before the races knowing what to do and how to react to people,” he continued. “Maybe there’s something we can do, like we did at VIR, be the first one to really make the move. You play it out from there and still go for the win.”

Garcia noted that fighting for a championship has become more difficult since IMSA aligned its GT classes to the worldwide FIA GT3 specification in 2022, mostly eliminating the performance disparity that existed between GTD class cars and slightly faster GTLM entries. GTD and GTD PRO now also use a standardized Michelin tire, whereas in the GTLM era, manufacturers worked with Michelin to develop tires for their specific car.

Corvette Racing had been a pure factory program since the early 2000s.
However, the shift in regulations required Chevrolet and Pratt Miller Motorsports to create the first-ever Corvette GT3.R for customer sales. Ford Racing quickly followed suit with a GT3 version of the Mustang.

“GT1, GT2, GT Le Mans…they were really cool cars to drive, and we had a lot of fun with those cars during those years,” recalled Garcia. “The transition to GT3 was a little bit difficult, or different, because we had a transition year with a bit of a mix until the Z06 GT3.R was able to race.
But I don’t see many, many differences, because there is always a superb level of drivers and good teams you’re fighting against.

“This is my 16th year with the team, and the approach has always been the same,” he added. “The Corvette Racing mentality has always been the same and the approach to every single race or championship has been the same regardless of the actual class of car we were running. This is just another year we are very happy and proud that we are in contention.”

Driving for IMSA’s most established and successful GT-class team, the No. 3 Corvette pairing has the championship-tested mettle going into Motul Petit Le Mans over Costa and the DragonSpeed Ferrari, which are in their first full season of GTD PRO competition. Chevrolet leads Ferrari by 46 points in the GTD PRO Manufacturer’s championship.

“The last two years, we came up short, but we are looking forward to showing and use all the knowledge we have to be in this position,” Garcia said. “Let’s see if we have enough of everything pace, race strategy, and I would say a little bit of luck.
“Let’s hope everything falls in the right direction, and we can come up with another championship.”

BoP - BMW, Corvette, Ferrari, Lexus Receive Power Increases in GT

Multiple GT manufacturers will head into the ten-hour season finale at Michelin Raceway Road Atlanta with power increases.

It notably includes the BMW M4 GT3 EVO (+4.2 percent), Chevy Corvette Z06 GT3.R (+4.1 percent), Ferrari 296 GT3 (+3.9 percent) and Lexus RC F GT3 (+5.1 percent), all at first-stage power levels below 190 km/h.

The Lamborghini Huracan GT3 EVO2 is the big gainer in second-stage power, getting a 3.7 percent increase since the last round at Indianapolis Motor Speedway, with the BMW notably receiving a 2.4 percent boost.

BMW’s power increase in both stages, however, comes amid a 12kg increase in the car’s minimum weight, the same amount the Ferrari 296 GT3 has also been handed.

The Ford Mustang GT3 has also been weighed down with an additional 7kgs since the last race, while the Lamborghini gets a minor 2kg weight increase.

All GT cars, except for the Lamborghini (+1.7 degrees) and Porsche 911 GT3 R (-1 degree) receive a 1 degree increase in minimum rear wing angles.

GTD PRO, GTD honors on the line in IMSA season-finale at Road Atlanta

DETROIT (October 7, 2025) It’s Championship Weekend for Corvette Racing and its Chevrolet Corvette Z06 GT3.R teams. The Corvette GT3 program has plenty to race for Saturday in both the GTD PRO and GTD classes at the 10-hour Petit Le Mans at Michelin Raceway Road Atlanta.

This year’s running is the 28th annual race and again serves as the finale for the IMSA WeatherTech SportsCar Championship. Four Corvette Z06 GT3.Rs dot the 53-car entry list with two each in the GT classes.

As a program, Corvette Racing has raced at the 2.54-mile, 12-turn Road Atlanta circuit every year since 1999 with eight Petit Le Mans victories…but none since 2010.
Part of that is down to Corvettes routinely being in championship contention whenever the race rolls around.
This year could prove different with narrow points leads for Corvette Racing by Pratt Miller Motorsports in GTD PRO and AWA in the GTD Akin

Award standings
Corvette Racing by Pratt Miller Motorsports (GTD PRO)
• No. 3 Corvette Z06 GT3.R: Antonio Garcia/Alexander Sims/Daniel Juncadella
• No. 4 Corvette Z06 GT3.R: Tommy Milner/Nicky Catsburg/Nico Varrone

A positive result at Petit Le Mans will add to the already-impressive Corvette Racing honor roll in IMSA GT competition: a 15th Manufacturers Championship for Chevrolet, a 15th Drivers Championship and a 16th Teams Championship for Corvette Racing by Pratt Miller Motorsports.

The scenario is pretty simple. Garcia and Sims who will team with Juncadella lead the GTD PRO Drivers standings by 18 points with 385 total points available; the points difference between first and second is 30 points, it’s 20 points per position from second place to fifth place and 10 points between the remaining spots.
The most likely scenario is that the highest-finishing entry between the No. 3 Corvette Z06 GT3.R and the No. 81 Ferrari will take the Drivers and Teams titles.

In the Manufacturers race, Chevrolet enjoys a 46-point lead heading into Petit Le Mans. Both Pratt Miller-run Corvettes can contribute to the points haul at Road Atlanta, so stakes also are high for the No. 4 Corvette of Milner, Catsburg and Varrone. A second podium finish would go a long way toward securing Team Chevy another full-season championship.

AWA (GTD)

• No. 13 Corvette Z06 GT3.R: Matt Bell/Orey Fidani/Lars Kern
The AWA team’s situation is even more straight-forward than the No. 3 Corvette. At stake for Fidani and the No. 13 Z06 GT3.R is a second straight Bob Akin Award championship and the return trip to the 24 Hours of Le Mans in 2026.

Fidani is tied for the lead in the Akin Award standings, which rewards the highest points-scoring Bronze driver in the GTD class. AWA seized the lead at the start of this season thanks to a victory at the Rolex 24 At Daytona for Fidani, Bell and Kern, and the lead has gone back and forth in the second half of the year.
Long-distance races have been a strong point for the AWA trio as the No. 13 Corvette has contended for wins and podium finishes in the other four endurance races on the IMSA calendar.

DXDT Racing (GTD)

• No. 36 Corvette Z06 GT3.R: Charlie Eastwood/Alec Udell/Salih Yoluc
DXDT Racing has high hopes entering the final race of its debut season in the WeatherTech Championship. Like the AWA lineup, the trio of Charlie Eastwood, Alec Udell and Salih Yoluc tested at Road Atlanta in mid-September to gear up for DXDT’s first crack at Petit Le Mans.

Between the three drivers, both Udell and Yoluc have one start each in Petit Le Mans while Eastwood will make his Road Atlanta debut. Despite that and in their first season as a trio, they have contended for multiple race wins in the long-distance events this year including leading in GTD late at both Sebring and Watkins Glen.

Petit Le Mans is the first of two consecutive season finales for DXDT Racing with the Corvette Z06 GT3.R. It will race for the GT World Challenge America Pro-Am title next week in the Indianapolis Eight Hours.
The 10-hour Petit Le Mans is scheduled for 12:10 p.m. ET on Saturday, October 11. The race will air live on NBC from noon to 3 p.m. ET and with live streaming on Peacock in the United States and IMSA.com outside the U.S. from noon to 10:10 p.m. ET. IMSA Radio will provide the audio call at IMSA.com, XM 206 and SiriusXM Online 996.

CORVETTE RACING BY PRATT MILLER MOTORSPORTS PRE-EVENT DRIVER QUOTES

ANTONIO GARCIA, NO. 3 CHEVROLET CORVETTE Z06 GT3.R:

“We know what we need to do now to win the championship for us, Corvette Racing and Chevrolet. We definitely will have to race our Corvette hard as there won’t be an opportunity for us to ease off with such a small points gap. We just need to continue doing the same things we have been doing for many years now execute, make no mistakes and be on top of the strategy.
That’s been the key to many of the race wins and championships that Corvette Racing has achieved.
While I still really want to finally win this race, I want to win my sixth championship more!”

ALEXANDER SIMS, NO. 3 CHEVROLET CORVETTE Z06 GT3.R:

“It feels like the entire championship happens in this one race. Lots and lots of things go on that throw the championship battles in one direction or the other throughout. It’s a phenomenal track to drive. It’s got some great undulation and quick flowing corners. There are parts of the track where the speed differential is quite great, so the GTPs are always chomping at the bit to overtake on the outside.
That creates some sketchy race moments, to be honest.

“This is going to be a crazy race. It always is at Petit Le Mans. All sorts of mayhem can happen. We want to try to optimize our package as absolutely as best as we possibly can to see if we can extract a bit more pace than what we had at Indianapolis.”

DANIEL JUNCADELLA, NO. 3 CHEVROLET CORVETTE Z06 GT3.R:

“Road Atlanta is a big highlight to finish off the IMSA season. It’s been awhile for me not to be in that championship and with Pratt Miller. I’m excited for that one. It’s an amazing racetrack and one of my favorites in the U.S. I got to win that race back in 2023 and will be back with Antonio and Alex. Antonio, even though he’s a legend in the States, hasn’t won that race yet so hopefully we can finish the season on a high with a win there.”

TOMMY MILNER, NO. 4 CHEVROLET CORVETTE Z06 GT3.R:

“Ultimately for the 3 Corvette guys and for us in the 4, championships are the talk. While the Drivers Championship for us is out of reach, we can certainly help Antonio and Alexander, but obviously the Manufacturers Championship is the No. 1 goal. Whether the 3 car guys have a good race or a bad race, we also need to be performing at the highest level we can so we are as far forward as possible.

I’d love to be able to take as many points away from the other manufacturers. The more Corvettes we have up front, the better that is for the championship. As we know at Petit Le Mans, anything can happen the later it gets so it’s about ultimately executing as well as we possibly can. As drivers, we lean on our experience to guide us through challenging situations. The same goes for the crew and the team. We’re in a good position. We just need to continue to execute at a high level.”

NICKY CATSBURG, NO. 4 CHEVROLET CORVETTE Z06 GT3.R:

“Petit Le Mans is a very big and very important race every year and this year is no different. We saw a little bit at Indianapolis how crazy the traffic can be and how easy it is to have contact that can alter your race. So we need to be mindful of that as there is still a lot to race for my first Petit Le Mans win, the first for the team in many years and the Manufacturers Championship as well as helping Antonio and Alex in the Drivers Championship. It’s going to be a busy and hectic race. I can’t wait for it.”

NICO VARRONE, NO. 4 CHEVROLET CORVETTE Z06 GT3.R:

“I’m super happy to be back in the No. 4 Corvette for Petit Le Mans. For me it’s an honor. I feel really at home with the team. It’s exciting for us to be able to fight for the Manufacturers Championship. The guys have done a great job during the year to be in this position. We also have the possibility for the No. 3 Corvette to win the Drivers and Teams championships. For sure those are the two most important things that we will try to achieve in this last race.

“I’m excited to be back with Tommy and Nicky and Tyler (Neff, race engineer). I think we make a super lineup. We will try to achieve all our goals and do our best to win the race. This is such a unique race with a lot of history and everyone wants to win. I can’t wait to be back in it and start working with the team again.”

AWA PRE-EVENT DRIVER QUOTES

MATT BELL, NO. 13 CHEVROLET CORVETTE Z06 GT3.R:

“It’s a slightly different picture to last year where we just had to start the race in order to get our ticket to Le Mans. This year we’ve got to finish ahead of the No. 70. It’s been a real back and forth competition all season. Some races definitely have gone in our favor, some in theirs, and it’s ended up where we are tied going into the last race. We enjoy competing against each other.
I think there’s a good relationship between the two teams, but both of us want to go to Le Mans, and only one of us can win the invite.

“This is always a fascinating race with multiple championship battles up for grabs, which probably makes this, in my opinion, the hardest sports car race in the world when you throw in the traffic, the length of the track and the amount of cars out there with everything on the line. So we’ll have our little battle in the middle of it all, and see how we get on.”

OREY FIDANI, NO. 13 CHEVROLET CORVETTE Z06 GT3.R:

“The Bob Akin Award has been a goal for us all year. Heading into Petit Le Mans tied at the top of the standings shows how strong our program has been, but the job isn’t done yet. Matt, Lars and the entire AWA crew have worked tirelessly to put us in this position, and now it’s about executing one last time. Winning the award and earning a return to Le Mans would be an incredible way to finish the season.”

LARS KERN, NO. 13 CHEVROLET CORVETTE Z06 GT3.R:

“Last race of the year, full send! I can’t wait to wrap up this amazing season on a high note and give both AWA and Team Chevy what they deserve. We haven’t had a single team penalty or car failure all season long, which is magnificent and rare in endurance racing. It’s a testament to the top-tier work everyone has been putting in all year, and I know we have the potential to do something big and achieve what we’re setting out to accomplish.”

DXDT RACING PRE-EVENT DRIVER QUOTES

CHARLIE EASTWOOD, NO. 36 CHEVROLET CORVETTE Z06 GT3.R:

“I’ve never done Petit Le Mans and did my first two-day test at Road Atlanta about a month ago. It was a really cool experience. The track is unbelievable. I’ve done a fair bit on the sim in the past but when you are there you realize how steep the undulations are on the track. It’s a great circuit to drive in the Corvette, especially that first sector through Turn Five.

It’s very fast and right on the edge. I’m looking forward to it. This is always a race I’ve wanted to do for quite a few years now. It looks like a really tricky race going into the night with almost 60 cars on a pretty short lap. Things will be really packed up but it’s just another element to the race.

“We’ve been super unlucky this year not getting the results we’ve wanted this year. For the whole DXDT Racing team, I hope we can get a solid result to finish out the year on a high. All the team have put in some much work but haven’t had the trophies to show for it. We’ll be going hard to make sure we finish the season getting them a trophy.”

ALEC UDELL, NO. 36 CHEVROLET CORVETTE Z06 GT3.R:

“Coming into the last IMSA race of the season, it’s a bittersweet feeling. On one hand, we’ve had a very strong team, great performances and execution. For a first-year team, I’m extremely proud of everyone’s efforts. On the other, we are missing that result and one of our team members still. As we go into Road Atlanta, it’s the last opportunity to bring everything together.

We’re all gunning for that podium and that breakthrough result to give the hard-working guys and gals at DXDT Racing the satisfaction for all the effort through the year. Our hearts are still with Colten and it’s good to see him making progress in his recovery. I’m excited to get on-track with our Z06 GT3.R and show what we can do.”

SALIH YOLUC, NO. 36 CHEVROLET CORVETTE Z06 GT3.R:

“Testing at Road Atlanta was beneficial. This is going to be a really busy race as we saw at Indianapolis. The biggest challenge that everyone will face is getting to the final two or three hours and in the dark.
I think we have a good chance to do that based on the testing we did there last month.
There was a lot we can take from that and Indianapolis to give us the best chance of success at Petit Le Mans.”
