Formula 1 2021 engine rules revamp details revealed

Formula 1 bosses have revealed details of the 2021 engine plans that were presented to teams on Tuesday

Formula 1 2021 engine rules revamp details revealed

F1 teams met with the FIA, the commercial rights holder and potential new manufacturers in Paris to discuss the objectives for the new engine rules that will be introduced for the 2021 season.

Work will continue for another 12 months on the details of the new engine specification, and the FIA said that the design and development of the new power units will not be possible until that process is complete - ensuring that F1's existing manufacturers will continue working on their current engines through 2018.

The proposal for 2021 includes keeping the current 1.6-litre V6 turbo hybrid engine, but running it at 3000rpm higher "to improve the sound".

In order to try to simplify the internals of the power unit, the MGU-H will be removed, and several prescriptive design parameters will be introduced to "restrict development costs and discourage extreme designs and running conditions".

These will include internal and external parameters, with the latter allowing for what the FIA described as "a plug-and-play engine/chassis/transmission swap capability".

A single turbo with dimensional constraints and weight limits will be mandated, while a standard energy store will be introduced alongside control electronics, which have long been standard in F1.

The MGU-K will be made more powerful, with a focus on manual driver deployment of the additional power, similar to the way KERS was used when it was first introduced into F1 in 2009.

This feature will also give drivers the option to save up energy over several laps to increase the tactical elements involved in racing.

Discuss the new engine rules on the Autosport forum

An FIA statement added that "during the remaining part of 2017 and 2018, the FIA and F1 will also work with the teams to establish power unit test and development restrictions as well as other cost containment measures".

F1 sporting boss Ross Brawn said: "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.

"The proposal presented today was the outcome of a series of meetings which took place during 2017 with the current teams and the manufacturers who showed their interest to be part of the pinnacle of motorsport.

"Also, we've carefully listened to what the fans think about the current power unit 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."

Fuel regulations, and potential limits on the number of fuels used, will also be investigated.

A series of meetings will now commence with all interested parties to develop the proposal in what the FIA described as "the spirit of the widest possible cooperation".

The difference between Mercedes’ stumble and the fall of F1 giants

OPINION: Mercedes endured its worst season of the hybrid Formula 1 era, but was mercifully spared its first winless campaign in over a decade late on. It has owned up to the mistakes it made which led to its troubled W13. And while its task to return to title-challenging contention is not small, its 2022 season seems more like a blip than the beginning of a downward spiral.

How Red Bull's dynamic leader shaped its F1 philosophy

The death of Dietrich Mateschitz last month has not only deprived Red Bull of its visionary founder, it has shorn Formula 1 of one of its most influential benefactors. Mateschitz himself was famously media-shy, preferring to let the brand do the talking on his behalf. And, while it’s now normal to speak of Red Bull F1 titles and champions made, Mateschitz never assumed it would be easy or even possible – as ANTHONY ROWLINSON discovered during this previously unpublished interview from 2006…

The 2022 Formula 1 season will be remembered as a record book rewriting Max Verstappen masterclass, a completely different challenge to his maiden world championship last year, and a clear sign he is still raising his own level. But where does it stack up against the all-time great F1 campaigns?
