FIA Extends Power Unit Component Allowance Through 2028

The FIA has decided to maintain the increased power unit (PU) component allowances introduced for the current 2026 season through 2028. Originally intended as a one-year transition bridge to mitigate the teething troubles of the new engine formula, the allowance will now remain in place for the next two seasons.

Why it matters:

Transitioning to a new engine architecture—specifically the removal of the MGU-H and the increased reliance on the MGU-K—is notoriously volatile. By extending this leeway, the FIA is prioritizing reliability and stability over strict penalties. This ensures that manufacturers can fine-tune the delicate balance between internal combustion and electrical power without the constant threat of grid penalties hindering sporting competition.

The Details:

• Expanded Allocation: Through 2028, drivers are permitted four internal combustion engines (ICE), four turbochargers, and four exhaust systems, alongside three energy stores, three control electronics units, and three MGU-Ks per season.
• The Evolving Power Split: The extension coincides with gradual technical shifts in how power is delivered:
  • 2026: 53% ICE / 47% Electric
  • 2027: 58% ICE / 42% Electric
  • 2028: 60% ICE / 40% Electric
• Race Distance Impact: To accommodate higher fuel flow requirements resulting from the 2027 power shift, Grand Prix distances (excluding Monaco) will be trimmed from 305km to 290km for the 2027 season.

What's next:

While race distances are expected to return to their standard lengths in 2028, the technical focus will shift toward optimizing the final 60/40 power ratio. The extended allowance provides a vital safety net for teams as they finalize these adjustments, ensuring the 2028 season debuts with a matured and reliable power unit landscape.
