After running separate opening round events at Sebring International Raceway and Spring Mountain for Porsche Sprint Challenge North America by Yokohama and Porsche Sprint Challenge USA West – both series are set to feature on the same weekend for the first time this year at Sonoma Raceway this weekend.
Between the two series, a total of 63 Porsche race cars are entered – both the Porsche 911 GT3 Cup and the Porsche 718 Cayman GT4 RS CS versions.
It won’t be just the individual championship battles on the line at Sonoma; the weekend also will feature the second round of the Porsche Endurance Challenge North America.
All the Sonoma race action from both championships will be streamed live on the Porsche Motorsport North America YouTube channel.
The opening round of Porsche Sprint Challenge North America by Yokohama was held at Sebring International Raceway last month with teenage newcomer Cole Kleck making an immediate impact by sweeping both Pro-Am races in the GT3 Cup category with Topp Racing.
The rookie finished ahead of fellow Texas driver and 2024 Porsche Carrera Cup Pro-Am champion, Alan Metni in both instances. Robert Tutino – who was a two-time polesitter at the historic circuit in 2023 – finished third twice with his Canadian outfit, VPX Motorsports.
In the 992 GT3 Cup Masters class, David Williams controlled the first race of the weekend to win with TPC Racing, in addition to finishing third on the overall podium.
The battle for the remaining Masters podium positions, though, was a duel between Daryn Dean and Scott Blind. While the latter held the runner-up spot at the start, he gave way to Dean with 20 minutes to go in the contest.
However, it was a reversal in Race 2 on Saturday, as Blind – the 2024 Sprint Challenge 992 GT3 Cup Masters champion – captured his first victory of 2025.
In the Cayman battle, Jens Hanston added his name to a long list of drivers who successfully continue to climb the Porsche Motorsport ladder.
In 2023, Hanston emerged atop the PCA Club Racing GTD2 podium charts. Two years later to open the 2025 Porsche Sprint Challenge North America season, he finished atop both races for the Cayman GT4 RS Clubsport class.
Hanston held off fierce pressure from Kellymoss racer Loni Unser in both races. Unser wasn’t the only female on the grid who had an impressive opening weekend, as Anna Cecchi scored a double podium with a third female racer, Erika Hoffmann finishing fourth in both events in Pro-am.
In the Cayman Masters class, Alain Scalzo – who finished second in the 2024 Cayman Masters championship – had a dominant performance in both races.
Blind backed up his race two Sebring win with a solo run to victory in the opening round of Porsche Endurance Challenge North America.
The Ruckus Racing driver sealed his win with 10 minutes remaining in the two-hour enduro. Blind made his winning pass on fellow Sprint Challenge Masters driver Daryn Dean, driving inside of Turn 17 and setting sail to win by more than four seconds.
Dean, meanwhile, co-drove to his own Pro-Am class victory alongside Alec Udell and the Kellymoss team while still finishing second overall.
The duo of Charlie Hayes and Reinhold Krahn finished second in the Am class behind Blind, while Frank Vitiello and Daniel Bloom paired up to finish third.
Rounding out the Pro-Am class was Mike Mim and Zachary Vanier in second, with Dan Ammann and Owen Trinkler in third.
In the Porsche Cayman GT4 RS Clubsport categories, Charles Espenlaub and Brandon Chappell with HM Road Racing finished first amongst the Pro-Am pairings after starting the race first-in-class.
Two weeks ago, another young star shone bright to take both race wins in the Porsche Sprint Challenge USA West opening round at Spring Mountain Motorsports Ranch.
After finishing on the podium multiple times but eluding victory in 2024, Luke French conquered the top step for the first time in both rounds, driving a Porsche 911 GT3 Cup for Competition Motorsports. French was untouchable at Spring Mountain, starting from pole, and leading every lap en route to the win.
Behind French, however, was an avid battle between drivers Daniel Hanley and Brannan Hankins, with Competition Motorsports and Loftus Motorsports, respectively.
Hanley bested Hankins by an even three-tenths of a second in Race 1 for runner-up, while Hankins flipped the deck on Sunday to secure second by nearly 11 seconds.
In the 992 GT3 Cup Masters category, Premier Racing’s Douglas Brandt led home his teammate Michael Lando in both races.
While the weekend sweep by Henry Marshall will go down in the Porsche 718 Cayman GT4 RS Clubsport victory books, it was not easy to achieve. However, a home-track advantage certainly helped, as his HM Road Racing team – based out of Spring Mountain – started both rounds first and finished first.
Following behind were a handful of pursuits. Tim Smith – a data team specialist-turned-driver for BR Racing – finished runner-up within two seconds of Race 1 behind Marshall and in third place after Race 2.
Meanwhile, Greg Herback – Smith’s teammate at BR Racing – fought for his inaugural podium of the season after finishing fourth in Race 1 and climbing past his competitors in Race 2 for the runner-up spot.
This weekend at Sonoma, a total of six sprint races will be contested across the two championships with the weekend finishing with a 90-minute battle at the second round of Porsche Endurance Challenge North America on Sunday.

Porsche Sprint Challenge USA West by Yokohama welcomed many new drivers in 2025, and Spring Mountain Motorsports Ranch was the backdrop for their introduction this past weekend for the opening event in 2025.
After finishing on the podium multiple times but eluding victory in 2024, Luke French conquered the top step for the first time in both rounds, driving a Porsche 911 GT3 Cup for Competition Motorsports. French was untouchable at Spring Mountain, starting from pole, and leading every lap en route to the win.
Behind French, however, was an avid battle between drivers Daniel Hanley and Brannan Hankins, with Competition Motorsports and Loftus Motorsports, respectively.
Hanley bested Hankins by an even three-tenths of a second in Race 1 for runner-up, while Hankins flipped the deck on Sunday to secure second by nearly 11 seconds.
In the 992 GT3 Cup Masters category, Premier Racing’s Douglas Brandt led home his teammate Micheal Lando in both races.
While the weekend sweep by Henry Marshall will go down in the Porsche 718 Cayman GT4 RS Clubsport victory books, it was not easy to achieve. However, a home-track advantage certainly helped, as his HM Road Racing team – based out of Spring Mountain – started both rounds first and finished first.

In the second year of Porsche Endurance Challenge North America by Yokohama competition, Scott Blind opened the season with a victory at Sebring International Raceway – and did so individually in the Am class.
Blind’s victory was his first in Endurance Challenge after finishing as high as fourth in 2024, and it came on the heels of a Porsche Sprint Challenge North America Masters class victory on Saturday at the central Florida racetrack.
Finishing first overall and running the Porsche 992 GT3 Cup car, the Ruckus Racing driver sealed his win with 10 minutes remaining in the two-hour enduro. Blind made his winning pass on fellow Sprint Challenge Masters driver Daryn Dean, driving inside of Turn 17 and setting sail to win by more than four seconds.
Dean, meanwhile, co-drove to his own Pro-Am class victory alongside Alec Udell and the Kellymoss team while still finishing second overall.
The duo of Charlie Hayes and Reinhold Krahn finished second in the Am class behind Blind, while Frank Vitiello and Daniel Bloom paired up to finish third. Both teams were elevated to their finishing positions after Alan Metni, running second-in-class, pulled off with an issue on the Ulmann Straight with three minutes remaining.
Rounding out the Pro-Am class was Mike Mim and Zachary Vanier in second, with Dan Ammann and Owen Trinkler in third.
In the Porsche Cayman GT4 RS Clubsport categories, Charles Espenlaub and Brandon Chappell with HM Road Racing finished first amongst the Pro-Am pairings after starting the race first-in-class.
Tom Kopczynski – who had his own podium in Sprint Challenge Cayman Masters on Friday – and Eric Filgueiras followed suit in second place, with the father-daughter duo of Greg and Anna Cecchi in third. The younger Cecchi, who introduced her father to the sport, finished third in both Sprint Challenge Cayman Pro-Am rounds earlier in the weekend.
Bill Fenech and Chris Hall landed atop the Cayman Am class, while the Tartaglione pairing of Reginald and Emanuel finished second. Griff Asplundh in a solo outing led for multiple laps of the race, but finished in third.
The second of four Porsche Endurance Challenge North America by Yokohama rounds takes place in one month’s time at Sonoma Raceway on April 4 – 6.

The 2025 Porsche Sprint Challenge North America season kicked off in thrilling fashion at Sebring International Raceway over the weekend, where over 60 cars took the green flag for an intense weekend of racing.
The event featured a breakout performance from teenage newcomer Cole Kleck, who made an immediate impact by sweeping both Pro-Am races in the GT3 Cup category with Topp Racing.
In the Porsche 718 Cayman GT4 RS Clubsport class, Jens Hantson followed suit, securing back-to-back victories in dominant fashion.
The GT3 Cup Masters class saw an intense battle between Daryn Dean and Scott Blind, with each driver claiming a victory to split the weekend’s honors.
Meanwhile, Alain Scalzo asserted his dominance in the Cayman Masters class, claiming both wins with commanding performances.
With fierce battles, standout rookie performances, and tight competition across the field, the season opener set the stage for an exciting year ahead.
Nearly 40 cars took the green flag at Sebring International Raceway to start the Porsche Sprint Challenge North America GT3 Cup season – a number consistent to the year prior, showing the series’ year-over-year strength.
Perhaps that strength is what attracted teenage phenom Cole Kleck to the series, and the newcomer was quick to success with two victories in the Pro-Am class with Topp Racing.
Because both 35-minute plus one-lap races on Friday and Saturday saw a handful of cautions, Kleck’s performance with the 992 GT3 Cup was limited except when blasting off on the restarts.
The rookie finished ahead of fellow Texas driver and 2024 Porsche Carrera Cup Pro-Am champion, Alan Metni with Kellymoss, in both instances. Robert Tutino – who was a two-time polesitter at the historic circuit in 2023 – finished third twice with his Canadian outfit, VPX Motorsports.
In the 992 GT3 Cup Masters class, David Williams controlled the first race of the weekend to win with TPC Racing, in addition to finishing third on the overall podium.
The battle for the remaining Masters podium positions, though, was a duel between Daryn Dean and Scott Blind. While the latter held the runner-up spot at the start, he gave way to Dean with 20 minutes in the contest.
It was a reversal in Race 2 on Saturday, however, as Blind – the 2024 Sprint Challenge 992 GT3 Cup Masters champion – captured his first victory of 2025. Blind started second behind Dean, but emerged unscathed from a contact maneuver to pass for the lead and go on to finish fourth overall.
Dean finished second, while Race 1 winner Williams finished third for a double podium weekend.
Next, Porsche Sprint Challenge North America takes part in a joint event with its series counterpart, Porsche Sprint Challenge USA West, at Sonoma Raceway on April 4 – 6.

At Sebring International Raceway, Jens Hanston added his name to a long list of drivers who successfully continue to climb the Porsche motorsport ladder.
In 2023, Hanston emerged atop the PCA Club Racing GTD2 podium charts. Just two years later to open the 2025 Porsche Sprint Challenge North America season, he finished atop both races for the Cayman GT4 RS Clubsport class.
Hantson started from pole position on Friday and Saturday for Speedsport Tuning, and led flag-to-flag in both instances for the double victory. Prior to the rounds at Sebring, his Sprint Challenge experience only consisted of two starts at Road America in 2024 with a best finish of seventh.
The lack of professional experience is hard to believe based on Hanston’s efforts to hold off the fierce Porsche Cayman of Loni Unser. In Race 1, Unser raced door-to-door with him at the start, but gave way before the winding sequence of Turns 3, 4 and 5 at the historic circuit. The two volleyed for the fastest lap times in the closing minutes, but Unser finished two seconds behind her competitor.
In Race 2, Unser loomed larger than ever in Hanston’s mirror throughout the 35-minute plus one-lap race. Despite being within tenths of the lead, the Kellymoss driver collected her second runner-up finish of the weekend by .609 seconds.
Unser wasn’t the only female on the grid who had an impressive opening weekend, as Anna Cecchi scored a double podium – third in both rounds – of her own with CHR. It was Cecchi’s second and third race behind the wheel of a Porsche racecar.
In the Cayman Masters class, Alain Scalzo – who finished second in the 2024 Cayman Masters championship – had a dominant performance in both races. The Scalzo Autosport driver finished 13 seconds ahead of second place in Race 1 and 18 seconds ahead by the checkered flag of Race 2. He also finished third place on the overall podium in both contests.
Bill Fenech with JDX Racing kicked off his 2025 campaign with two podiums at Sebring, finishing third on Friday and second on Saturday. Meanwhile, Tom Kopczynski finished second in Race 1 and Dan Ammann finished third in Race 2.
Next, Porsche Sprint Challenge North America takes part in a joint event with its series counterpart, Porsche Sprint Challenge USA West, at Sonoma Raceway on April 4 – 6.
