FIA Greenlights TPC Testing with Doubling Power Unit Costs for F1 2026 Season

A recent accord by the FIA will permit Formula 1 teams to continue conducting TPC (Testing of Previous Cars) sessions, a practice that has grown in importance for vehicle development and nurturing emerging talent. These sessions, typically utilizing cars at least two years old, enable teams to fine-tune engineering and give promising drivers crucial track experience. Notably, teams like McLaren and Red Bull have extensively leveraged TPC to refine their current machinery and evaluate future prospects, leading to the establishment of a new FIA regulation that limits current F1 drivers to 1,000 kilometers in these older vehicles.
Looking ahead to the 2026 Formula 1 season, a substantial number of teams are poised to transition to new engine manufacturers. This shift presents a unique challenge for TPC continuity, as older cars are intrinsically linked to their original power unit suppliers. Following extensive dialogue, the FIA has intervened, implementing a mandatory two-year supply obligation. This means engine manufacturers with expiring contracts will be compelled to provide their previous client teams with current-spec power units for TPC activities. While this ensures testing can proceed, industry sources from the Belgian Grand Prix weekend suggest that power unit costs for TPC will significantly escalate, potentially doubling. Despite this, teams are likely to absorb the increased expenditure, as TPC running is exempt from the sport's strict budget caps, allowing them to allocate additional funds without impacting their primary development budgets.
This strategic move by the FIA aims to maintain competitive parity and driver development opportunities amidst a period of significant technical transition in Formula 1. By ensuring access to necessary power units, even for those changing suppliers, the sport safeguards the vital role TPC testing plays in preparing for future seasons. While the financial burden on teams will be greater, the long-term benefits of sustained testing and talent development are deemed paramount for the sport's evolution and competitive health.
