F1 and its governing body FIA is growing tired of hearing Formula 1 fans complain about the lack of the racing series’ famous loud noises as well as some of the race carmakers’ issues of parity—and they are taking action.
To manage the fans’ expectations and excitement, FIA’s first action is the revision of the power unit rules but will only take effect starting on the 2021 season. Second, the proposed rules still call for a 1.6-liter V-6 which means that even though the redline will be increased from 15,000 rpm to 18,000 rpm, tortured screams of demons won’t be heard.
What is more significant though is the removal of the Motor Generator Unit-Heat (MGU-H) which converts heat from the turbo into electrical energy that can either be stored in the battery or used as an immediate power booster.
The 2021 edition will instead focus on the Motor Generator Unit-Kinetic (MGU-K), a kinetic energy recovery component which is more powerful “with [an] option to save up energy over several laps to give a driver controlled tactical element to racing.”
Other proposed changes for the sake of keeping the costs down and being inclusive of mid-pack and back-marker teams are:
- Restrict development costs which translates to prescriptive internal design parameters to discourage extreme designs and running conditions;
- Weight limits and dimensional constraints on single turbo;
- Standard energy store and control electronics;
- High level of external prescriptive design in order for ‘Plug-And-Play’ engine/chassis/ transmission swap capability;
- Allow investigation on tighter fuel regulations and limits on number of fuels used;
FIA would meet with manufacturer representatives to finalize the new rules framework. They are expected to release the new rules at the end of this year. However, the information needed for design and development will not be available until the end of 2018.
