The sound of F1 could be set for an upgrade with higher rev limits among the proposed changes to the power-unit specifications for 2021 as revealed today.
Following a meeting in Paris between FOM, the FIA and all current and potential engine suppliers, the current 1.6-litre V6 Hybrids will remain with a few improvements.
The sport will retain the basic configuration of the 1.6-litre V6 hybrid turbo power units which were introduced in 2014. However the recovery of power from waste heat via an MGU-H will be dropped in favour of more powerful kinetic energy generators (MGU-Ks).
Drivers will be given greater control over when they choose to use the energy harvested by the power units.
From 2021 the rev limit will be raised by 3,000rpm to 18,000rpm. This is intended to improve the sound generated by the engines.
