Now entering its fifth year, the country’s fastest racing series builds on the momentum of a tightly contested 2025 campaign, where championship battles in both SR3 and SR1 went down to the final rounds. The championship returns with its established four-round format across Clark International Speedway and Batangas Racing Circuit.

Following last season’s dramatic finale, defending champions are expected to return as they aim to retain their crowns, while challengers look to reset the championship narrative. Interest from new drivers continues to grow, with anticipation building for a stronger and more competitive grid in 2026.

Performance levels across the championship have steadily risen, with lap records falling throughout 2025 and overall pace improving across both classes. Fueled by race-engineered SeaOil Extreme-97 fuel, drivers continue to extract more from the Radical platform — reflecting not only growing skill, but also the consistency and reliability required at the highest level of competition.

“As we stage the SeaOil Radical Challenge Philippines in 2026, we are proud to power the competition with high-performance fuels engineered for the extreme demands of racing. Every lap calls for consistency, reliability, and peak output — and that is exactly what SeaOil delivers, commented Mark Yu, SeaOil President for Retail & CFO. “Beyond performance, this partnership reflects our commitment to advancing local motorsport. Together with Radical, we are building a stronger platform for Filipino racers to sharpen their skills, compete at the highest domestic level, and raise the standard of racing in the country.”

“Radical Motorsports Philippines is proud to announce the commencement of our long-term partnership with SeaOil Philippines,” shared Mike Consenheim, Radical Motorsports Philippines President. “We have officially launched the 2026 SeaOil Radical Challenge, with succeeding editions already secured for the years ahead. In addition, several new initiatives are in development that not only the Philippine motorsports community, but the public can look forward to.”
