Formula 1’s leaders have revealed details of the sport’s evolution of power unit regulations, beginning in 2021, which will focus on creating simpler, cheaper and louder powertrains. The 1.6-litre V6 turbo-hybrid platform will be retained.
The proposals, released on Tuesday, have been jointly developed by the FIA and Formula 1 with input from teams, manufacturers both inside and outside the sport, and other experts.
A number of changes will be implemented to the current V6 turbo-hybrid concept, which debuted in 2014, in a bid to reduce costs, improve engine loudness and increase overall fan appeal.
The key features of the 2021 power unit model are as follows:
- The 1.6-litre V6 turbo-hybrid platform will be retained, with a single turbo and dimensional / weight limits
- Engine rev limits will be increased by a further 3,000rpm to improve the sound
- Prescriptive internal design rules will be tightened to contain development costs and discourage extreme running conditions and the use of exotic materials, as well as to give ‘plug-and-play’ capabilities to more easily swap power units and transmissions from season-to-season
- The MGU-H will be removed
- A standard Energy Store and Control Electronics will be developed and supplied to all manufacturers
- The MGU-K will be made more powerful and allow for manual driver deployment to open the options to save harvest energy over several laps for more tactical deployment
- An intention to investigate tighter fuel regulations and limits on the range of fuels which can be used.
The overall framework for the 2021 power unit model will be published by the FIA before the end of the year. The governing body has indicated it will delay releasing the complete design and development guidelines to ensure that the sport’s existing manufacturers continue developing their current-spec power units until 2020.
“The 2021 power unit is an example of the future way the FIA as regulators, F1 as commercial right holders, the teams and the manufacturers as stakeholders will work together for the common good of the sport,” Ross Brawn, F1’s Managing Director of Motorsports said in a statement.
“The proposal presented today was the outcome of a series of meeting which took place during 2017 with the current teams participating in the FIA Formula 1 World Championship and the manufacturers who showed their interest to be part of the pinnacle of motor sport.
“Also, we’ve carefully listened to what the fans think about the current PU and what they would like to see in the near future with the objective to define a set of regulations which will provide a powertrain that is simpler, cheaper and noisier and will create the conditions to facilitate new manufacturers to enter Formula 1 as powertrain suppliers and to reach a more levelled field in the sport.
“The new F1 has the target to be the world’s leading global sports competition married to state of the art technology. To excite, engage, and awe fans of all ages but to do so in a sustainable manner. We believe that the future power unit will achieve this.”
A sequence of meetings will now begin with all interested parties “to discuss and develop the proposal in the spirit of the widest possible cooperation”, he added.
