F1 bosses revealed details of the new engine plans set to be introduced to the sport in 2021.
The proposal for four years time includes keeping the current 1.6-litre V6 turbo hybrid engine, but having it running at 3000rpm higher to improve the sound.
And in order to attempt to simplify the internals of the power unit, the MGU-H will be removed.
“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,” said Ross Brawn, F1’s MD, Motorsports.
“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.”
The overall framework for the 2021 power unit definition will be published by the FIA at the end of 2017.
“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,” continued Brawn.
The key features of the proposals presented to manufacturer representatives at Tuesday's meeting:
- 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
