Much less gasoline, extra electrical energy; we clarify what adjustments F1’s new engine laws will convey.

The FIA World Motor Sport Council has authorized the brand new F1 engine laws that may come into impact in 2026. Whereas the brand new energy models will keep it up with the present 1.6-litre V6 inside combustion engine, there are some essential adjustments that pave the way in which for Porsche and Audi to enter F1.

The brand new guidelines got down to make F1’s energy models extra environment friendly, requiring much less gasoline, whereas nonetheless placing out over 1,000hp. So what are these adjustments, and can they have an effect on the on-track racing? We break it down for you:

Goodbye MGU-H, good day Audi and Porsche

From 2026, F1 is disposing of the advanced MGU-H (Motor Generator Unit – Warmth), which captures power from exhaust gases. It’s a transfer supposed to encourage new producers like Porsche and Audi to hitch the fray. The MGU-H has little relevance to highway automobiles and it’s understood that the Volkswagen Group had been reluctant to decide to the expense of creating the system.

The FIA has said that the brand new guidelines “are supposed to make it attainable and enticing for newcomers to hitch the game at a aggressive stage”. In step with that, the elimination of the MGU-H can even scale back any benefits the present energy unit producers have.

Earlier this yr, former Volkswagen Group chairman Herbert Diess had already introduced Audi and Porsche’s plans to enter F1. With the brand new guidelines formally authorized, each manufacturers can now go forward with formally confirming their entry.

Porsche might be teaming up with Crimson Bull for a brand new engine partnership, and whereas Audi’s plans aren’t as concrete, it’s anticipated to tie up with Alfa Romeo.

Extra electrical energy

To make up for the lack of the MGU-H, the MGU-Okay – which recaptures power underneath braking – will generate thrice extra electrical energy. At present, each MGUs generate 120kW of power, however that is set to extend to 350kW from simply the MGU-Okay in 2026. So it is going to be in a position to acquire much more braking power that will in any other case be wasted.

Regardless of the diminished gasoline circulation and ensuing decrease energy, the added electrical power means the automobiles will nonetheless churn out over 1,000hp. And there’s an additional deal with for followers – F1 says the brand new energy models might make the automobiles louder too.

Much less gasoline

The brand new energy models will use absolutely sustainable gasoline, generated utilizing non-food biomass and even via carbon seize by drawing CO2 from the ambiance. Which means no new fossil carbon might be burned, and you’ll head right here to be taught extra about how this tech might assist make inside combustion engines greener.

The mix of the automobile adjustments and elevated electrical energy means the automobiles will want much less gasoline to run. F1 is aiming for every automobile to make use of simply 70kg of gasoline throughout a race from 2026 onwards. This can be a main discount from the 100kg of gasoline utilized by automobiles in 2020. In 2013, this determine stood at 160kg for a single race. Moreover, the fuel-flow fee might be restricted by power reasonably than quantity.

Return of turbo lag

The MGU-H helped keep away from turbo lag, so that might very nicely return in 2026. It’ll be trickier for drivers to manage the automobile at nook exits, so it will be attention-grabbing to see how that performs out.

There’s additionally the technique facet of all of it. With the administration of upper electrical power, deciding when and how you can assault will develop into much more important.

Security

The MGU-Okay might be enclosed inside the chassis, proper subsequent to the battery and management electronics. With this, all of the high-voltage gear will now be contained inside the security cell.

Retaining prices in examine

Quite a lot of measures might be launched to maintain prices in examine, together with an engine-specific price cap and banning of pricey manufacturing supplies. Extra engine elements might be standardised or provided from a single supply and dyno hours might be restricted as nicely.

However this doesn’t imply innovation might be restricted. Engineers could have the liberty to maintain creating electrical methods.

Sustainability

From 2026, it is going to be obligatory for batteries to be recycled, and moreover, supplies akin to cobalt might be recycled on the finish of the MGU-Okay’s life as nicely.
