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.
Hoffmann joins list of female winners in Cayman GT4 RS Clubsport
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.
Kleck, Blind solidify 992 GT3 Cup titles with wins at Road Atlanta
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.
