As internal combustion wanes, what will power F1 cars of the future?

LONDON — Carmakers and governments have identified as time on the inside combustion engine as they change to electrical but Method A person sees a lot of existence in it nevertheless as the sport races in the direction of a zero-carbon future.

Current grand prix cars and trucks use a highly successful 1.six litre V6 turbo hybrid electric power device, a significantly cry from the gasoline-guzzling V12 and V10 monsters of outdated, and a new “strong and emotive” a single is thanks in 2025 to run one hundred% on sustainable fuels.

The sport hopes to set the specification by June this year.

“Whilst several folks could consider the inside combustion engine is lifeless, I would argue it is significantly from lifeless,” chief technical officer Pat Symonds told a current Motorsport Market Affiliation (MIA) conference on electricity-successful motorsport.

“Sustainable fuels is our massive drive in Method A person, and it is a thing I consider we’ll have to roll down into other formulas (also).”

The to start with samples of one hundred% sustainable gas, from next technology bio-squander, were being sent to F1’s electric power device suppliers — Mercedes, Ferrari and Renault in 2022 with Honda leaving and handing over their engineering to Purple Bull — last December for screening.

The existing gas has a 5.75% biocomponent, escalating to ten% sustainably sourced ethanol from 2022.

Method A person aims to realize a web zero-carbon footprint by 2030, but the high-tech sport faces issues about its relevance in a environment significantly centered on thoroughly clean electricity and climate alter.

Britain, with a flourishing motorsport business and house to most of the ten teams, strategies to ban the sale of new petrol, diesel and hybrid cars and trucks from 2030.

Method E founder Alejandro Agag has instructed F1 will at some point have to merge with his all-electrical sequence that started up in 2014.

Equally are sanctioned by the Worldwide Auto Federation (FIA), which has accredited Method E as its sole electrical championship until 2039.

Some others argue battery engineering is not the resolution for all forms of motorsport, even in the lengthier-phrase.

Combustion engines, quite quite possibly two-stroke, employing fossil-cost-free fuels could deliver F1 the essential performance and speed when also retaining the audio enthusiasts really like and that electrical racing lacks.

“We have a huge total of history and tradition based mostly about inside combustion and it is just not likely to go absent overnight. Nor do we want it to,” mentioned Iain Wight, company enhancement director for Williams Superior Engineering.


Previous Audi Activity engine head Ulrich Baretzky saw hydrogen combustion engines as a future route for Method A person as perfectly as stamina races like Le Mans, which strategies a hydrogen group for 2024.

“In 2025 we will (continue to) see combustion engines (at Le Mans), since the (gas) electricity density is unbeatable at the moment with any engineering we know nowadays,” he told the conference.

“Five decades later on I hope we will see a mix concerning hydrogen, combustion, gas mobile.”

Williams F1 CEO Jost Capito, a previous Volkswagen Motorsport boss, mentioned the Porsche 911 sportscar would by no means go electrical but could be carbon neutral.

He mentioned a huge effort would be wanted to make improvements to the price tag and performance of biofuels, and produce far more successful hydrogen creation, but motorsport could increase to the challenge.

Chemical big INEOS, co-operator of Method A person champions Mercedes, is now a single of Europe’s most important hydrogen producers.

“There are systems that go in numerous instructions but all aiming at the exact same objective, to be CO2 neutral. For me this is a seriously thrilling time,” mentioned Capito.

David Richards, chairman of Motorsport United kingdom and engineering business Prodrive, cautioned it would be “a massive punt” to say in which motorsport would be in ten years’ time.

He warned that politics would enjoy a component, with electrification offered by governments as a “awesome and very simple” resolution.

“We’ve noticed (suppliers) withdrawing from most features of what we would regard as typical inside combustion engine motorsport,” mentioned Richards.

“But possibly if we can get these engines functioning on choice fuels, if we can maybe use hydrogen both in a uncooked condition in an inside combustion engine or through a hydrogen gas mobile, we can draw in the suppliers again.”
