The Formula One Group and the FIA revealed today the sport's proposed engine rules which are scheduled to be introduced in 2021.
The backdrop for the new engine format included lower costs, less sophisticated technology and a louder sounding unit.
F1 will therefore retain the current architecture of the 1.6-litre V6 hybrid turbo power units which were introduced in 2014.
The single-turbo engine will rev at 3000rpm higher however in order to "improve the sound".
Furthermore, the future unit will no longer include the troublesome MGU-H element which has been dropped in favor of additional powerful kinetic energy generators (MGU-Ks). Interestingly, drivers will be able to control when the extra boost of power shall be deployed.
"The proposals shared today have been developed jointly by the FIA and by F1 using data and input from teams, power unit suppliers and outside experts, and the overall framework for the 2021 power unit definition will be in place and published by the FIA at the end of 2017," said the FIA in a joint statement with Formula 1.
"In order to uphold the objective of cost reduction, work will continue over the next 12 months to define certain elements of the Power Unit, but the design and development of the complete Power Unit will not be possible until all the information is released at the end of 2018.
"This aims to ensure that manufacturers continue to work on the current specification Power Unit."
A series of meetings will now commence with all the interested parties to discuss and develop the proposal in the spirit of the widest possible cooperation.
"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," said Ross Brawn.
"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."
Manufacturer representatives were presented with the vision for the key new features of the 2021 Power Unit proposed by the FIA and F1. These are as follows:
-1.6 Litre, V6 Turbo Hybrid
-3000rpm higher engine running speed range to improve the sound
-Prescriptive internal design parameters to restrict development costs and discourage extreme designs and running conditions
-Removal of the MGUH
-More powerful MGUK with focus on manual driver deployment in race together with option to save up energy over several laps to give a driver controlled tactical element to racing
-Single turbo with dimensional constraints and weight limits
-Standard energy store and control electronics
-High Level of external prescriptive design to give ‘Plug-And-Play’ engine/chassis/transmission swap capability
-Intention to investigate tighter fuel regulations and limits on number of fuels used
