TPC, or Testing of Previous Cars, is an FIA-regulated practice that allows F1 teams to test old machinery away from a race weekend.
Formula 1, as the top-tier of motorsport, not only showcases top-tier engineering and racing talents, but also mirrors current trends in the automotive industry. The 2026 F1 regulations signify a shift towards a stronger emphasis on electrical energy, with significant changes to chassis and power unit rules. Notably, the removal of the MGU-H and the increased power of the MGU-K have attracted manufacturers like Audi, aligning with their goal of achieving net-carbon neutrality through electrification in racing. The 2026 season saw Audi and Cadillac entering the grid, with Cadillac facing challenges in Testing of Previous Cars (TPC) due to lack of prior models. TPC in F1 refers to sanctioned testing of previous cars, allowing additional testing throughout the season when new regulations are introduced. Despite opportunities for extended testing, FIA regulations impose restrictions on TPC, requiring a maximum of 20 days per competitor to ensure fair competition in the sport.
