With 55 days remaining until the cars hit the track, Porsche Sprint Challenge USA West by Yokohama is charging toward a fifth season packed with major additions to the calendar.
The 2026 schedule features a debut at Arizona’s APEX Motor Club, the series’ first appearance at the Velocity International at Sonoma Raceway, and a championship finale alongside IndyCar at WeatherTech Raceway Laguna Seca.
With entries now open, many of the championship’s long-time Porsche customer teams are expected to return, maintaining the core group that has defined the series since its launch in 2022.
“Porsche Sprint Challenge USA West has been built on stability, consistency, and the long-term commitment of our customer teams,” said Volker Holzmeyer, President and CEO of Porsche Motorsport North America.
“The 2026 calendar maintains that foundation while introducing exciting new venues such as APEX Motor Club, along with major events like Velocity International and the IndyCar weekend at Laguna Seca. These platforms give our competitors the opportunity to perform on a much bigger stage.”
February 6–8 — APEX Motor Club
The season opens with the championship’s first visit to the private Arizona facility.
April 10–12 — Sonoma Raceway (with PSCNA & PECNA)
A shared weekend aimed at reducing operational costs for teams competing across multiple Porsche One-Make programs.
May 7–9 — Circuit of the Americas (with PSCNA)
A return to COTA for a combined event with the national Sprint Challenge series.
May 29–31 — Sonoma Raceway (Velocity Invitational)
The series makes its debut at Velocity, one of North America’s premier motorsport festivals.
August 14–16 — Road America (with PSCNA & PECNA)
Another joint weekend designed to streamline travel and logistics.
September 4–6 — WeatherTech Raceway Laguna Seca (with IndyCar)
The season concludes at Laguna Seca, once again supporting the IndyCar weekend.
The 2026 season begins February 6–8 at APEX Motor Club, marking the championship’s first trip to the desert venue. The season opener will run in conjunction with the first Porsche GT Track Day of 2026, an exclusive experience designed for Porsche owners to unleash the full potential of their Porsche road cars in a motorsport environment.
APEX Motor Club is a members-only motorsport complex south of Phoenix, offering a purpose-built circuit and modern support facilities. It has quickly become a regular choice for track development programs and premium automotive events.
One of the most high-profile events on the calendar arrives May 29–31, when the championship joins Velocity Invitational at Sonoma Raceway.
Known for its premium fan experience, rare race machinery, and manufacturer showcases, Velocity brings Sprint Challenge competitors in front of one of the largest and most diverse motorsport audiences on the West Coast.
This will be the series’s first appearance at the event and is expected to be a significant highlight of the 2026 season.
“Velocity International is a perfect fit for Sprint Challenge,” Holzmeyer said.
“Some of the most significant Porsche race cars in history have competed at Velocity, including the Gulf-liveried Porsche 917 and Mark Donohue’s Penske Can-Am car. It is a world-class showcase that brings together enthusiasts, partners, and future drivers.”
The Velocity event is one of two visits to Sonoma Raceway in 2026. Round two of the championship will also be held at the venue, which has been a popular destination for the West Coast-based Porsche customer teams.
The championship will conclude September 4–6 at WeatherTech Raceway Laguna Seca, running alongside the NTT IndyCar Series.
The joint weekend provides a major-league stage for the final championship battles and continues Porsche Sprint Challenge USA West by Yokohama’s presence at one of America’s most historic racing venues.
Porsche has become the Official Car of WeatherTech Raceway Laguna Seca. This move paves the way for a new Porsche Driving Center at the track and accelerates the ongoing revitalization of the iconic circuit.
A key feature of the 2026 calendar is its strategic alignment with Porsche Sprint Challenge North America and Porsche Endurance Challenge North America events.
By pairing multiple Porsche programs at the same venues, teams benefit from reduced transportation and operational expenses while retaining the same level of technical support.
“Shared weekends help our teams race more efficiently without compromising on quality,” Holzmeyer noted. “It’s an approach that allows us to deliver a strong championship while keeping costs manageable.”
Joint weekends include:
Yokohama, the series longtime tire partner, enters 2026 with new product innovation tailored specifically to Sprint Challenge competition in the Cayman class.
“We’re thrilled to extend our partnership as the official tire supplier for Porsche Sprint Challenge USA West,” said Patricia Wall, Yokohama’s Senior Motorsports Manager.
“For 2026, we’ve developed brand-new front and rear tires specifically for the Porsche 718 Cayman GT4 RS Clubsport, engineered to deliver exceptional grip and consistency. We can’t wait to see these tires in action on the iconic tracks featured in the West series and especially at Apex Motor Club, an exciting new addition to the schedule.”
Last season produced an impressive group of champions across the Sprint Challenge USA West categories. Daniel Hanley captured the 2025 992 Pro-Am title, and Scott Blind earned the Masters championship, with both drivers attending the Porsche Night of Champions in December.
In the Cayman classes, Jack Parriott secured the Pro-Am crown, and Tom Rogers won the Masters division. Competition Motorsports completed the year as the Team Champion.
All Porsche Sprint Challenge USA West by Yokohama races will once again be broadcast live on the Porsche Motorsport North America YouTube channel, ensuring fans around the world can follow every lap of the 2026 season.
The popular Porsche Driver Development programs, including the Junior and Female Driver initiatives, offered by Porsche Motorsport North America (PMNA), will continue in 2026. Each program provides participants in Porsche customer racing with financial support and development tools to advance their motorsport careers.
PMNA has announced the details of the 2026 Porsche Junior and Female Driver programs, which support eligible drivers in Porsche Carrera Cup North America, Porsche Sprint Challenge North America, and Porsche Sprint Challenge USA West. Drivers competing in a Porsche who meet eligibility criteria in other open-competition championships, including IMSA and SRO, may also receive support through these programs.
The Porsche Junior program officially launched in 2021 alongside Porsche Carrera Cup North America but has its roots in the Porsche Young Driver Academy dating back to 2012. The Female Driver Program was introduced in 2022. Since their inception, both programs have helped develop the careers of prominent drivers within the Porsche Motorsport Pyramid North America, including Loek Hartog, Elliott Skeer, Seb Priaulx, Parker Thompson, and Kay Van Berlo, many of whom have achieved success on the world stage.
Both programs emphasize driver development through performance-based incentives, including race tires and entry fee support. Seminars during Porsche Carrera Cup North America race weekends cover topics ranging from performance thinking to car setup and driver-engineer communication, with guidance from Porsche racing legends Richard Westbrook and Patrick Long.
For the third consecutive year, a two-day seminar will take place at the Porsche Penske Motorsport shop in Mooresville, North Carolina. This in-depth program includes sessions on sponsorship activation, social media, physical fitness, mental training, and media skills.
“All of us at Porsche Motorsport North America are proud of the drivers who participate in these programs year after year,” said Volker Holzmeyer, President and CEO of PMNA. “The Porsche Driver Development programs have grown in both quantity and quality over the years, and we have seen graduates achieve great success. We wish next year’s class the same and welcome all aspiring drivers to the Porsche Motorsport Pyramid.”
In addition to training, both programs provide financial assistance.
Female Driver program participants receive 50 percent of entry fees for Porsche single-make races covered by PMNA. The top female driver in each Porsche Carrera Cup North America race earns a free set of tires for the next race weekend, with an additional set awarded to the top point scorer across the weekend. Top-scoring drivers in Sprint Challenge North America and Sprint Challenge USA West receive a free set of race tires for the following weekend’s events.
Similarly, Junior Program participants can earn race tires based on championship performance, as well as entry fee support in Porsche Carrera Cup North America. The highest-finishing drivers in each Porsche Sprint Challenge category may have their 2027 entry fees covered, helping them progress through the Porsche Motorsport Pyramid North America.
All of last year’s PMNA Selected Drivers came through the Junior Program. Riley Dickinson and Loek Hartog used awarded parts credits to compete in GT4 America in Porsche 718 Cayman GT4 RS Clubsport machinery. Tom Sargent competed with Wright Motorsports at Michelin Endurance Championship rounds in the IMSA WeatherTech Championship using similar program support.
Other drivers, like Zachary Vanier, leveraged their Junior Program experience to compete in Porsche Carrera Cup North America. After winning the Porsche Sprint Challenge North America title in 2023, Vanier has captured five Carrera Cup North America victories and represented North America at the Porsche Junior Shootout in Portugal. Paul Bocuse advanced through the Porsche Motorsport Pyramid North America, winning a Cayman Pro-Am championship in Porsche Sprint Challenge before moving to the GT3 Cup Pro-Am class and eventually to Porsche Carrera Cup North America in 2025.
The Female Driver Program continues to expand, growing from a single participant in its inaugural 2023 season to seven drivers in 2025. Three drivers—Sabré Cook, Madeline Stewart, and Ashley Freiberg—competed full-time in Porsche Carrera Cup North America in 2025. Loni Unser, Erika Hoffmann, and Anna Cecchi each won Porsche Sprint Challenge races, while Therese Lahlou achieved podium finishes in the highly competitive GT3 Cup Pro-Am class.
Porsche Sprint Challenge North America and Porsche Sprint Challenge USA West will continue their successful partnership with Yokohama Tire into the 2026 season, marking the tire manufacturer’s sixth consecutive year as Official Tire Partner and Presenting Partner of both USAC-sanctioned series.
Yokohama will also remain the Official Tire Supplier of Porsche Endurance Challenge North America for a third consecutive season. Across all three series, competitors will continue to race on Yokohama’s proven ADVAN A005 racing slicks and ADVAN A006 rain tires, ensuring consistency and performance across all classes.
The partnership extends beyond competition as Yokohama becomes the Presenting Partner of Porsche GT Track Day for 2026. The popular program runs in conjunction with Porsche Sprint Challenge race weekends, giving participants the chance to drive their own Porsche road car on the same tracks as the Sprint Challenge racers.
“USAC is a leader in motorsports and the Porsche Sprint Challenge series is an integral piece of our overall racing strategy,” said Andrew Briggs, Yokohama Tire’s senior vice president of marketing & product management.
“Once again, we’re excited and honored to continue our long-term partnership with USAC and showcase the capabilities of our ADVAN racing slicks in some of the most competitive one-make racing in North America.”
The collaboration between USAC and Yokohama has been instrumental in supporting the growth of the Porsche Motorsport Pyramid in North America, offering drivers a professional, competitive environment to develop their skills.
The 2026 Porsche Sprint Challenge North America by Yokohama season will feature 14 races across seven tracks, beginning at Sebring International Raceway in March.
The Porsche Sprint Challenge USA West by Yokohama championship will open its season in February at Apex Motor Club, with 12 races across six events throughout the year.
Both championships will continue to feature the 911 GT3 Cup (type 992.1) and the 718 Cayman GT4 RS Clubsport in four classes:
Meanwhile, the Porsche Endurance Challenge North America will return with a four-round schedule in 2026, featuring multi-class competition for the same pair of Porsche race cars. Drivers will compete in GT3 Cup Pro-Am, GT3 Cup Am, Cayman Pro-Am, and Cayman Am categories, all on Yokohama’s ADVAN tires.
“Porsche Sprint Challenge North America is a leading one-make racing series in North America,” said Patricia Wall, Yokohama’s motorsports senior manager. “It offers aspiring racers, as well as seasoned professionals, an incredible opportunity for adrenaline-fueled racing and a professional environment.”
“Yokohama Tire has become an integral part of USAC’s success story,” added Kevin Miller, president & CEO of USAC Racing. “Their passion for racing and commitment to technology perfectly align with our mission to deliver competitive, professional, and exciting motorsport experiences. We’re thrilled to continue building on that momentum together as we enter a new season of growth and on-track intensity.”
With Yokohama’s continued support and a refreshed calendar of events, Porsche Sprint Challenge North America by Yokohama, Porsche Sprint Challenge USA West by Yokohama, and Porsche Endurance Challenge North America are set for another season of competitive racing and continued growth as the foundation of the Porsche Motorsport Pyramid in North America.

JTR Motorsports Engineering capped off the Porsche Endurance Challenge North America four-hour finale with a statement-making 1-2 finish in the final race of the season at Road Atlanta.
The invitational class entry of Carrera Cup North America standout Ryan Yardley and teammate Dave Musial Jr. delivered the overall victory. New Zealander Yardley’s outright pace — including the fastest lap in class — and Musial’s steady stints gave JTR the top step and an emphatic showcase of the team’s strength.
Right behind them, JTR’s duo of Chris Hutter and team boss Jared Thomas secured second overall and the Pro-Am class victory.
Adding even more drama to the weekend, Scott Blind — the Am category ace — sealed the overall championship title by delivering a stunning class win with co-driver Alan Metni.
Metni was able to cross the line third after a dramatic chase of championship rival, and COTA winner Charlie Hayes (again teamed with Reinhold Krahn). Their dramatic battle came to a head when they made contact entering turn 10a with 17 minutes remaining.
While Metni was able to recover quicker, he was given a drive-through penalty by race officials. Despite the penalty, Hayes was unable to bridge the gap with his now damaged No. 233 entry and eventually crossed the line in fifth place (second in the Am class).
The result gave Blind a perfect three-for-three championship result at Road Atlanta, winning not only the Endurance Challenge 992 GT3 Cup Am title on Sunday, but also securing trophies in both Sprint Challenge North America and USA West, all with Ruckus Racing.
While Blind eased to his Sprint Challenge titles earlier in the weekend, he claimed a narrow victory in the Endurance Challenge, beating the season-long pair of Hayes and Krahn by just seven points.
In the 992 GT3 Cup Pro-Am class, Kellymoss racer John Gilliland solely took home the Endurance Challenge title with a third-place finish on Sunday with Riley Dickinson.
Of the Porsche 718 Cayman GT4 Clubsport Pro-Am cars, William Peluchiwski and Andrew Davis took home the final Endurance Challenge win of the year for Kellymoss. The winning pass by Davis – in his first Endurance Challenge outing – came before the half-hour mark and delivered teammate Peluchiwski’s best finish of the season.
The pair shared the podium with title winners Charles Espenlaub and Brandon Chappell, who captured the award by 64 points.
In the Cayman GT4 Clubsport Masters class, Reginald Tartaglione stamped his class championship with a win at Road Atlanta, pairing with Gary Bufkin for the first time of the season. In the previous three rounds, Tartaglione partnered with his son Emanuel, and their two wins with ProSport Competition set up the former for success on Sunday.

The 2025 Porsche Sprint Challenge North America by Yokohama and Porsche Sprint Challenge USA West seasons concluded at Road Atlanta with the Final Prost, presented by Good Boy Vodka, bringing together more than 250 drivers, crew members, sponsors, and families for the traditional year-end celebration.
The event recognized the achievements of competitors across both series, with championship hardware awarded in Cayman and GT3 Cup categories.
The evening reflected not only the results on track but also the growth of the Porsche Sprint Challenge platform, which continues to serve as a key stepping stone in the Porsche Motorsport Pyramid.
“This is now our fifth season, and I still remember in 2020 when Sprint Challenge didn’t exist,” said Volker Holzmeyer, President and CEO of Porsche Motorsport North America.
“We created the joint venture with USAC to get Porsche Sprint Challenge North America by Yokohama started, and it has been quite a transformation. Over the last five years, we’ve changed a lot, experimented a lot, but always with the focus on getting feedback from our customers — the drivers, the teams, the mechanics, the sponsors — to keep improving every year.
“On behalf of Porsche Motorsport North America, I want to congratulate all of our 2025 Porsche Sprint Challenge champions.
“Sprint Challenge has grown into one of the most competitive and important platforms in the Porsche Motorsport North America Pyramid, and the accomplishments of our champions are a reflection of the strength of the entire community. We look forward to building on this success together in 2026.”
Blind became a dual champion in 2025, securing GT3 Cup Masters titles in both North America and USA West. Hanley prevailed in a closely fought Pro-Am battle that came down to the final weekend, while Scalzo, Hantson, Rogers, Parriott, and Kleck each earned their first Porsche Sprint Challenge titles.
As overall championship winners, Kleck, Blind, and Hanston have earned invitations to the annual Porsche Celebration of Champions in Germany on November 29 this year.
“Topp Racing gives me the car that allows me to drive fast, and I’m so blessed to have them with me.
“It’s like family. My dad always tries to be the engineer, and Todd and Alex have to tell him to step back.
“But truly, this paddock feels like family — with Topp Racing, Porsche Motorsports, Eboost and everyone around us. I’m blessed to be a part of it.”
“On behalf of Team Ruckus, we really appreciate it. We’ve built such great friendships and camaraderie in this paddock.
“The folks from Porsche Motorsport North America and USAC have been fantastic, and of course thanks to Yokohama for their support.”
“It feels really good. I had to rebound from yesterday, but we got it done. Big shoutout to Speed Sport Tuning — they’ve been with me since 2019.
“I started racing here six years ago, my very first race, so it feels extra special to be here today celebrating.”
“This means a lot. It was our goal this year. Last year, we finished second in the championship and had a good shot, but maybe lacked experience. This year we achieved our goal, and we’re very pleased with it.”
“The important thing for us is that this paddock is the training ground for everything we do.
“It’s my favorite paddock to come to. The other teams are so supportive, as are the vendors, Porsche Motorsport North America, and USAC. It’s just a wonderful place to be, and we’re glad to keep coming here to develop our drivers.”
“It feels pretty amazing. First and foremost, a massive thank you to everyone at Competition Motorsports. They were the first team I ever worked with as a mechanic, so a lot of them have known me since I was a teenager.
“It feels really special. I’ve spent a lot of time in this paddock and gotten to know wonderful people here, and I’m grateful for all the support.
“Big thank you to my family, my mom, and my sister. It means a lot to feel that support.”
“It was super fun. As everybody knows, this isn’t an individual sport; it’s a team sport. I just get all the fun behind the wheel, which is great.
“Thanks to Porsche for a great car, and to Tatum Racing. The whole gang has been incredible. Especially thanks to my wife, Meg, for being here. It’s been a tough year, but really fun, and I appreciate everyone who’s been part of it.”
“It’s been a long year, but it means a lot to me to be out here working with our customers, fellow competitors, and really the whole motorsport community.
“One person I want to point out who’s done an exceptional job this year is Jeremy Sundt at Porsche Motorsport North America.
“I give him a hard time, but he’s been really good for the series, the sport, and for us. I also want to give a shoutout to the team — they’ve been absolutely awesome this year. The drivers have been great, everything’s been good.”
Porsche Mobil 1 Female Driver Program duo Erika Hoffmann and Loni Unser made history at Road Atlanta by taking the first all-female 1-2 finish in Porsche Sprint Challenge North America by Yokohama.
After Unser’s recent victory at Watkins Glen, her Kellymoss teammate Hoffmann claimed her first-ever series win at the Road Atlanta finale, leading Unser across the line in the opening Cayman Pro-Am race of the weekend. The result marked not only back-to-back first wins for both drivers but also the first time in series history that two female competitors finished 1-2.
The historic moment was one of many highlights of the final race weekend for Porsche Sprint Challenge North America for 2025, where nearly 30 Porsche race cars battled it out in the final championship-deciding fight of the season.
Erika Hoffmann faced incredible pressure in Race 1 from Kellymoss teammate Loni Unser but the pair were battling for second and third place on the podium. Only when leader Jens Hantson stopped with one minute on the clock did Hoffmann’s maneuvers versus her teammate lead her to her first win in the series.
Hoffmann’s first podium of the year came at Sonoma Raceway in April, and she celebrated fourth in the season-long championship behind fellow female racers Unser in second and Anna Cecchi in third.
The trio finished behind Hanston in the championship, who found his way back to first in Race 2. Hanston’s season had been dominant with Speedsport Tuning en route to the title – winning the final race of the season in addition to 10 others.
In the Cayman Masters class, Alain Scalzo was crowned the season-long champion following five wins in 2025. Scalzo’s two podiums – third in Race 1 and second in Race 2 – sealed the title.
However, it was Keith Grant in his first event with Sprint Challenge North America this season who captured both Masters class victories at Road Atlanta. Grant also placed on the overall podium in the two races.
Amongst Grant and Scalzo in the finishing order were Bill Fenech, second place in Race 1 and finishing second in the class championship, and Gary Bufkin for his first podium of the year in third during Race 2.
Both Cole Kleck and Scott Blind won class races at Road Atlanta en route to stamping their titles in Sprint Challenge North America.
The start of Race 1 was hectic for polesitter Alan Metni, Kleck in second and Danny Dyszelski in third, as the latter two tried to maneuver around the leader. In Kleck’s efforts, he tiptoed into the dirt and out of contention, but rebounded the following day by passing Metni within the opening minutes of the race.
It was Kleck’s 11th win of the season with Topp Racing – finishing more than 200 points ahead of the next closest competitor in the championship – while Metni’s victory in Race 1 was his second with Kellymoss. Also walking away with podium finishes in the Pro-Am class were Dyszelski in both instances and Malito in Race 1 after powering through the field from seventh.
In the 992 GT3 Cup Masters class, Scott Blind capped off a stunning season with seven wins, including podium finishes in all races throughout the season. His Race 1 win and second-place finish in Race 2 came after securing the Sprint Challenge USA West 992 GT3 Cup Masters title earlier in the day.
While Blind cruised to his title in the Ruckus Racing Porsche, Kayden Kelly took attention with his Race 2 win. With six wins of his own in 2025, Kelly battled Blind for the championship throughout the season, but settled for second.
Reinhold Krahn completed the podium in both Masters class races at Road Atlanta.

The Porsche Sprint Challenge USA West by Yokohama GT3 Cup Pro-Am championship came down to the wire at Road Atlanta, where Competition Motorsports driver Daniel Hanley secured the title with a dramatic final-race victory, edging out Brannan Hankins by just 0.628 seconds.
Hanley and Brannan Hankins entered the weekend tied on points in the title showdown.
Only by Hanley finishing one position higher than Hankins in both rounds did the former secure the class title. Hanley finished second to Metni on Friday, while winning on Saturday ahead of Hankins by less than one second. Hankins completed the podium in Race 1, while Mark Crigler scored his second podium of the season in Race 2.
In the Masters class, Scott Blind was the unequivocal champion in the series, having won eight of 10 races in the Porsche 992 GT3 Cup Masters class and scoring the most points of any Sprint Challenge USA West driver this season.
Blind closed out the year with two class wins at Road Atlanta, also finishing first overall in Race 2.
Given Blind’s dominance throughout the season, the Ruckus Racing driver was nearly uncontested for the title. However, Kyle Washington and Alessandro Chiocchetti battled hard at Road Atlanta in his wake – with both swapping the remaining podium spots of the weekend.
Winning Race 1 overall in the Porsche 992 GT3 Cup Pro-Am class was Alan Metni with Kellymoss, shining bright in the USA West division as Porsche Sprint Challenge North America and Porsche Endurance Challenge North America also joined the weekend’s action at the popular Georgia circuit.
In his first outing, Chad Knight scored his first Sprint Challenge USA win on Saturday in the Porsche 718 Cayman GT4 RS Clubsport Masters class. Knight entered a tight field of competition, but only when leader Tim Smith had a dizzying spin did he inherit the lead and eventual win.
Knight was lunging for the Race 2 victory on Saturday, but came second to title winner Tom Rogers and the Tatum Racing team. Greg Herback finished third in both rounds, en route to finishing second in the championship.
Jack Parriott won the Cayman Pro-Am class championship, securing four wins on the season ahead of Emanuel Tartaglione and Anna Cecchi.

After a season of near-misses and runner-up finishes, Loni Unser finally broke through for her first Porsche Sprint Challenge North America by Yokohama victory at Watkins Glen International.
Her long-awaited triumph stood out as the defining moment of a weekend where championship leaders strengthened their positions and last-lap battles kept the title fight alive. For Unser, it was the result of consistency, persistence, and a season spent pushing at the front by the Porsche Mobil 1 Female Driver Program member.
As a fourth-generation race car driver, Loni Unser celebrated one of her most significant racing accomplishments to date at Watkins Glen, as she captured her first Porsche Sprint Challenge North America by Yokohama victory with Kellymoss in the Cayman GT4 RS Clubsport category.
Through nine races in 2025, Unser had finished second five times in Pro-Am, and only with a last-lap shootout on Saturday did she pull off her first win. Polesitter and championship leader Jens Hantson led until a yellow flag flew with four minutes remaining. The race restarted at the white flag, and Unser maneuvered to the inside of Hantson approaching the inner loop for a smooth pass into the lead.
The win caps off years of hard work for Unser, who joined the Porsche one-make family and the Kellymoss squad in 2024. And in addition to sitting second in this year’s Sprint Challenge Pro-Am championship battle – her win breaks a tie with third-place Anna Cecchi – she revisited the Pikes Peak Hill Climb earlier this summer where she ran the quickest Porsche of the event and was the fastest female amongst her competition.
Behind Unser, Hantson finished second, but would regain the top step of the podium on Sunday. Similar to the day prior, Race 2 also featured a last-lap shootout, but Hantson refused to make the same error from Race 1 and went on for his ninth win of the year.
Spencer Propper completed Saturday’s podium – his first top-three of the season – while on Sunday, Hantson held off a hard-charging Anna Cecchi in second. Unser chased her female rival for the runner-up spot, but settled for third. The pair will battle for second place in the Pro-Am championship standings behind Hantson at the season finale.
In the Cayman GT4 RS Clubsport Masters class, the wins at Watkins Glen were split by Alain Scalzo in Race 1 and William Peluchiwski in Race 2. Both drivers led flag-to-flag en route to their victories. It was the first win for championship-leading Scalzo since Circuit of The Americas, while Peluchiwski’s win on Sunday was his second consecutive after winning at Road America earlier this month.
Peluchiwski finished second on Saturday behind Scalzo and ahead of Tom Kopczynski in third. Meanwhile, Sunday’s podium saw Bill Fenech second at the finish line, with Scalzo narrowly behind in third. Kopczynski, Fenech, and Dan Ammann will fight to decide the rest of the top-four finishing order in the Masters championship behind Scalzo at the finale.
It was the same story, but on two different days, in the Porsche 992 GT3 Cup Pro-Am class.
Cole Kleck started from the pole position in both races at Watkins Glen and led flag-to-flag for his fourth weekend sweep of the season with Topp Racing. Watkins Glen followed the one race of the season that Kleck had not won in 2025, and the youngster wasted no time in further extending his nearly untouchable Pro-Am championship lead.
Danny Dyszelski made identical moves of his own on Saturday and Sunday to claim runner-up in both contests. After starting on the second row both days, Dyszelski swept around Alan Metni – who began outside the front row – in the opening corners of Races 1 and 2 to take the spot. Metni held onto third both times, adding to his nearly double-digit number of podiums in 2025.
In the Masters class, Scott Blind returned to victory lane with Ruckus Racing for the first time since Circuit of The Americas in May. It was a crucial victory for Blind in his championship efforts, as his next closest rival, Kayden Kelly, scored the Race 2 win at Watkins Glen.
In the race they did not win, Blind and Kelly finished runner-up to each other, and the former holds a comfortable yet not unbeatable title lead over Kelly ahead of the finale.
While Saturday’s race ran green flag for the entire duration – and featured John Gilliland completing the Masters podium in third – a lengthy yellow flag on Lap 1 limited action in Race 2. Gilliland was part of the incident after his podium performance on Saturday, elevating Joel Johnson to third place.
Not only did the Porsche 992 GT3 Cup and Porsche 718 Cayman GT4 RS Clubsport classes complete their standard doubleheader at The Glen, the competitors also ran a third race to make up for what was cancelled at Road America earlier in the month due to inclement weather.
The 992 GT3 Cup classes ran their round on Friday at Watkins Glen, with Cole Kleck winning overall to kick off his eventual weekend sweep. A mid-race yellow flag interrupted the action, but Kleck excelled on the restart to finish ahead of Danny Dyszelski and Matthew Siegal in second and third, respectively.
In the Masters class, Scott Blind earned another class victory ahead of championship rival Kayden Kelly in second, while Reinhold Krahn finished on the podium for the third time this year.
The Road America make-up rounds bookended the weekend, as the Cayman GT4 RS Clubsport classes ran their third race of the weekend on Sunday afternoon to conclude the event.
Jens Hantson tallied his second victory of the day, winning overall in the Pro-Am class ahead of Loni Unser by less than half a second and Anna Cecchi in third. William Peluchiwski followed suit in the Masters class, winning both races of the day. It was an identical podium to the class’ contest in the morning, with Bill Fenech and Tom Kopczynski finishing second and third, respectively.
Road Atlanta hosts the final Porsche Sprint Challenge by Yokohama rounds of the year for both the North America and USA West series on September 12 – 14. Not only will champions be crowned across those respective classes, but Porsche Endurance Challenge North America by Yokohama will also run its final race of 2025 to determine its title winner after four rounds.
Race replays for Porsche Sprint Challenge and Porsche Endurance Challenge by Yokohama are available on the Porsche Motorsport North America YouTube Channel.

Porsche Motorsport North America gears up for 2026 with a full slate of one-make racing championships and track day events, set to deliver thrilling competition and unmatched on-track experiences.
Among the highlights is the return of Porsche Sprint Challenge North America by Yokohama to Barber Motorsports Park in March, joining the NTT IndyCar Series for the weekend. The Alabama stop adds to a schedule that blends legendary road courses, fan-favorite events, and opportunities for drivers at every level of competition.
All Porsche Sprint Challenge North America, Porsche Sprint Challenge USA West, Porsche Endurance Challenge North America, and Porsche GT Track Day events will continue to be sanctioned by the United States Auto Club (USAC), Porsche Motorsport North America’s official licensing partner.
From sanctioning and event operations to delivering Porsche GT Track Day, USAC provides the consistency and professional standards that drivers and teams rely on. For 2026, USAC will also continue to provide test day opportunities at most venues, giving current and prospective racers added track access to prepare for competition.
The 2026 PSCNA season once again spans seven weekends at premier U.S. circuits, but the spotlight falls on the return to Barber Motorsports Park, March 27–29, where the championship will share the stage with the NTT IndyCar series.
The Barber event combines the atmosphere of a major national race weekend with the pure competition of Porsche’s one-make format, giving drivers a showcase opportunity in front of passionate crowds.
The year opens at Sebring International Raceway before heading to Barber, followed by visits to Sonoma Raceway, Circuit of the Americas, Virginia International Raceway, and Road America. The season finale is scheduled for Road Atlanta in September, where PSCNA will wrap up another highly competitive campaign.
PSCUW once again brings the thrill of Porsche single-make sprint racing to the western U.S., with a six-event calendar that emphasizes variety and accessibility, offering mixed-class competition where drivers in the 911 GT3 Cup and 718 Cayman GT4 RS Clubsport compete side-by-side.
The series opens in February with a first-ever visit to Apex Motor Club in Arizona, expanding to a new region and adding a fresh challenge to the schedule.
From there, PSCUW joins PSCNA at Sonoma and Circuit of the Americas before returning to Sonoma in May for Velocity Invitational, one of the most unique racing festivals in the country.
Later in the summer, the series will now join PSCNA & PECNA at Road America, creating another marquee combined weekend on the calendar. An exciting season finale awaits for Porsche Sprint Challenge USA West–where the series will join IndyCar’s finale at WeatherTech Raceway Laguna Seca September 4–6.
The 2026 Porsche Endurance Challenge season will feature four rounds, each running alongside a Porsche Sprint Challenge North America weekend. Drivers will begin at Sebring International Raceway before heading to Sonoma Raceway in April.
After the summer break, the championship resumes at Road America in August before closing the year at Road Atlanta in September.
The format continues to attract both single drivers and co-driver lineups in the Porsche 911 GT3 Cup and 718 Cayman GT4 RS Clubsport, with longer race distances and a mandatory pit stop window adding layers of strategy to the competition.
Building on the momentum of its first full season, Porsche GT Track Day has quickly become one of the most exclusive ways for owners to experience their personal Porsches on track. In 2026, the program returns for four dates at some of North America’s most exciting venues.
Apex Motor Club, Circuit of the Americas, and Road Atlanta join the calendar for the first time, alongside a return to Sonoma Raceway.
With expectations of large turnouts at each stop, Porsche GT Track Day offers enthusiasts unmatched access to iconic circuits, generous track time, VIP hospitality, and a behind-the-scenes view of a Porsche race weekend.
The 2026 season blends classic tracks, new venues, and a variety of racing formats that together showcase the depth of Porsche’s one-make racing.
With new & returning venues, including fan-favorite events like Barber and Velocity, plus the continued growth of Porsche GT Track Day, the 2026 season is shaping up to be one of the most exciting yet.
