F1 lays out 2021 engine regulations

The FIA has revealed initial proposals for the 2021 engine regulation changes at a meeting with current and future manufacturers as well as the commercial rights holder.


The overall framework of the changes will be published at the end of the year but the design and development will not be released until the end of next year, thus allowing the teams to continue development on their current spec power units.

The changes proposed included keeping the current 1.6 litre V6’s with dimensional and weight restrictions on the single turbo.

The engines will rev at 3000rpm higher in a bid to improve the sound which has been one of the prominent complaints from fans about the current spec units.

In order to make the engines less complicated, the MGU-H will be removed while MGU-K will be made more powerful and manual. Meaning it will be up to the driver when to use the extra deployment, similar to the KERS system used from 2009-20013.

There will be a standard control electronics and energy store, an external design to allow for ‘plug and play’ swap capability between engine/gearbox/chassis and internal design parameters to restrict development costs and extreme designs.

Finally, the FIA intends to launch an investigation into fuel regulations and the number of fuels that can be used.

A statement from F1 motorsports managing director said:

“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.”

He added: “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.”
