FIA extends extra F1 power-unit component allowance through 2028

F1 drivers will retain a higher power-unit component allowance in 2027 and 2028, extending a concession that the 2026 rulebook had limited to one season.

Article B8.2.3 of the new 2027 sporting regulations allows each driver one additional example of every power-unit element listed in Article B8.2.2 in 2026, 2027 and 2028. The listed allocations are four internal combustion engines, four turbochargers, four exhaust systems, three energy stores, three control-electronics units, three MGU-Ks and six ancillary power-unit components. Without the extension, each allocation would have been one unit lower.

The allowance came with F1’s revised hybrid power-unit formula in 2026. The V6 remained, but the MGU-H was removed and greater emphasis shifted to the electrical side through the MGU-K. The combustion engine’s share of total output is set to rise from 53% in 2026 to 58% in 2027 and 60% in 2028, while the electric motor’s share moves from 47% to 42% and then 40%.

The higher allocations give power-unit manufacturers more room before component use brings grid penalties into play.
