When looking at Spencer Pumpelly and Luca Mars’ 2026 season, which included a dominant winning streak stretching across seven races at four different venues, it’s almost hard to believe that the championship ultimately came down to one single point in the last sprint of the year. The Pirelli GT4 America Silver class champions put in a string of commanding performances in the No. 028 RS1 Porsche, but in the end still proved that every single result matters in the long run.
Pumpelly and Mars established themselves as the pairing to beat with an extraordinary run that began at the Lone Star Enduro at Circuit of The Americas. The double-points event gave the RS1 duo an early opportunity to make a significant move in the standings before carrying their momentum into the next round, and the next, and so on.
The winning run included weekend sweeps at Sebring International Raceway, Road Atlanta and Road America, with the No. 028 Porsche consistently finding its way to the front. For Pumpelly, he believes a systematic approach was central to the streak.
“I think RS1 has always had a methodical approach to every step of the race weekend, from pre-race prep all the way through to the checkered flag,” Pumpelly explained. “Luca and I bought into the system, and the results were almost expected. Luca also put in some great drives when we needed them, and the seven-race win streak continued thanks to a true team effort.”
Mars and Pumpelly complemented each other perfectly, while the RS1 crew executed whenever needed to turn their performances into sustained top results. Every trip to victory lane further strengthened their position in the standings, building a points cushion that would prove crucial.
But even during their dominant stretch, their resilience was tested. Road America presented an unusual challenge when a crash during practice left their Porsche damaged ahead of the race weekend.
With time running short, fellow Porsche team NOLASPORT stepped in to help, allowing RS1 to use its backup car. The unexpected assistance gave Pumpelly and Mars a chance to keep the fight alive, and the duo responded by sweeping the weekend despite the disruption. That success at Road America would become even more important as the season entered its final two events.
The momentum proved harder to maintain at Barber Motorsports Park, where Pumpelly and Mars missed the podium in both races. Meanwhile their rivals RAFA Racing Team championship rivals continued to close the gap, setting up a tense conclusion to the season at Indianapolis Motor Speedway.
Race 1 at Indianapolis brought another result outside the top three, leaving the RS1 duo with one final opportunity to secure the championship on track. They still had a decent gap, but it was still a now-or-never situation. But their hopes of improving their points tally in the finale were cut short when the No. 028 Porsche was collected in an incident on the opening lap of Race 2, taking them out of the running completely.
Pumpelly and Mars were left watching from the sidelines, unable to influence the outcome directly. Their championship fate depended on how the remaining contenders finished.
Pumpelly acknowledged the frustration of seeing the title fight end that way, particularly after the consistency RS1 had demonstrated throughout the summer.
“After a strong run through the middle of the season, we had some bad luck come into play,” he said. “In racing, no matter how much you prepare and execute, luck can always play a factor, and the last four races of the year proved that. Watching from the sideline after our car was taken out by a competitor wasn't the finish we had planned, and it felt awful not being in control of our result, but in the end our summer success proved vital to our October finish.”
Ultimately, the points accumulated during their seven-race winning streak were enough. Pumpelly and Mars finished the season with 259 points, securing the Silver class championship by a single point over RAFA Racing Team.
“I think the biggest takeaway from the season is that the team of people RS1 assembles to compete at this level makes all the difference,” Pumpelly shared. “Luca blew me away with his speed and consistency, and the crew was the best out there. The championship is an amazing accomplishment made even better by the people on this team.”
Mars shared that sentiment, emphasizing how the team's resilience and collective commitment carried them through both the ups and downs of the winning streak and the difficult conclusion.
“The seven-victory stretch was key for winning the championship,” Mars stated. “The team showed up every weekend, and Spencer and I and the whole team gave our best and were resilient all season.”
“The final race was a whirlwind of emotions,” he continued. “After the incident, I was getting ready to head home, and then my team said we still had a chance. Then we found out we won, and it was unreal and very rewarding.”
The 2026 Pirelli GT4 America Silver class title was not secured with a final-race victory or a last-lap pass. Instead, it was earned through the accumulated value of a total season's work, underlining just how much the team's earlier results had mattered.
“The championship means a lot to me, showing what the RS1 team can do and how well we work as a team,” Mars said. “And it means a lot showing the hard work Spencer and I put in.”
Pumpelly and Mars leave the 2026 season as Silver class champions by the narrowest of margins, a fitting conclusion to a campaign defined by every single step taken through the year and an exceptional display of teamwork and resilience, and a winning streak that laid the foundation for their success.
