Formula 1 stakeholders have reached an agreement for grand prix cars to use a new type of 'green' engine from 2013. The sport will switch from the current 2.4-litre V8s to 1.6-litre four-cylinder turbo engines with energy recovery systems and fuel restrictions.
The move is an attempt to mirror the trend towards fuel-efficiency in road cars and to popularise it, increasing public demand for such engines.
The new rules could be confirmed by governing body the FIA on 10 December.
Mercedes and Ferrari had been reluctant to agree to the move as recently as a month ago, believing that it was an unnecessary expense at a time when F1 was trying to reduce costs.
But a spokesman for Ferrari told BBC Sport the rules had been agreed and he would be "surprised" if it was not announced by the world council.
He admitted Ferrari had concerns about the move on cost grounds but added: "An agreement is there, and when there is an agreement you work accordingly."
A high-level source involved in the talks said it was "most likely" that the FIA would announce the move on Friday.
The aim is for the new rules to improve the efficiency of F1 engines by as much as 50%.
Care has been taken to ensure the performance of cars will not be affected and total power outputs will remain at current levels - approximately 750bhp.
By adopting the regulations, F1 hopes to widen its appeal to sponsors - commercial insiders say some companies are reluctant to get involved in F1 because of its image of being wasteful with resources.
The agreement to change the regulations from the 2.4-litre normally aspirated V8s used in F1 since 2006 comes after months of protracted negotiations and it had looked as if the switch might have to be delayed until at least 2014, and perhaps until as long as 2017.
F1 commercial boss Bernie Ecclestone has been firmly opposed to the rule change.
He told BBC Sport: "We have a very good engine formula. Why should we change it to something that is going to cost millions of pounds and that nobody wants and that could end up with one manufacturer getting a big advantage?"
But the change has been agreed in a series of recent meetings between F1's current engine manufacturers - which also include Renault and private company Cosworth - and the final touches were put to the regulations by a steering group of F1 engineers on Thursday.
F1 ENGINE RULES FROM 2013
1.6-litre, four-cylinder turbos with energy recovery and fuel restrictions to replace current 2.4-litre normally aspirated V8s
Fuel efficiency to increase by a target of 50%
Overall power to remain same at approx 750bhp
Checks and balances to ensure costs are contained and performance across all engines remains comparable
Plan for advanced 'compound' turbos to be introduced in subsequent years
Power of Kers energy recovery systems to increase from 60kw in 2011 to 120kw in 2013


It is understood that a series of checks and balances have been written into the regulations to keep costs down and to ensure it should be impossible for one manufacturer to steal a march on the others in terms of performance.
This will primarily be done through resource restriction - such as limiting the amount of people or time that can be devoted to a project.
German car giant Volkswagen has also been heavily involved in the discussions and has privately indicated to F1 insiders that the only way it would consider entering F1 would be if the sport adopted these new rules.
However, sources say VW is giving conflicting messages about whether it will commit to an F1 engine project. If it did enter the sport, it is expected to use its Audi brand.
BBC Sport has been told the regulations will go before the F1 Commission - a group of stakeholders that agrees all rule changes - on Thursday 9 December before being rubber-stamped by the World Council the following day.
The move is a triumph for both F1 teams' organisation Fota and FIA president Jean Todt, both of whom have made increasing the future sustainability of F1 a key aim.
Leading figures in F1 hope that the adoption of the new rules will insulate the sport from charges of wastefulness at a time when supplies of fossil fuels are diminishing and there is pressure for the world to cut its production of greenhouse gases.
The sun is setting on the era of big-capacity normally aspirated F1 engines


The aim is that by associating these energy-saving, fuel-efficient technologies with a glamorous and popular sport, they will become desirable in road cars, where their use is already increasing dramatically.
About 600bhp of the 750bhp produced by the engines will come from the four-cylinder single-turbo engine itself, with the rest being provided by energy storage and power-boost systems.
These systems - known as Kers - were first used in F1 in 2009 before being abandoned for 2010 and are being reintroduced next season.
For 2013, the power capacity of the Kers systems will be increased from 60kw to 120kw.
Fuel consumption will be restricted both by limiting fuel flow and introducing a maximum capacity for races.
The new engines will not do more than 10,000 revs per minute - current F1 engines spin at 18,000rpm.
In subsequent years, complex new turbocharging technology called compounding will be introduced to further enhance efficiency.
The regulations have been framed to encourage the pursuit of efficiency in engine design, dramatically increasing the amount of power that can be produced per litre of fuel burnt.
Those lessons in efficiency can then be transferred to road cars so that considerably less fuel is used for a given amount of performance.
The FIA was unavailable for comment.


So, all good in theory. I was concerned that the power levels would go down massively (i read figures as low as 550hp previously).

However i am worried that 4 cylinder engines at 10k rpm are going to sound crap, and i know that's 'not' important but i love racing engine sounds and would hate to see F1 being pushed down the route that has ruined top end prototype racing...

Wonder if it will give the cars a different look also, going back to roll hoops with no air intake above the drivers heads.


I wouldn't at all be surprised if more teams start adopting that system Mercedes have, even as soon as next season!

From a kid going to the F1s I think the turbo cars were only around 12k rpm back in the last turbo era and they still were pretty loud. Its a different sound to the V10's or V8's but still impressive.

obviously they were V6 but its similar displacement.

Turbo 4's baby thats what I talking about :thumbup: !!!

Does not sound like crap to me :wink: .

S2000's are NA VTec yo

Your preaching to the Pope homeslice, Yo ! I realize that a turbo engines sound is muffled by the turbo compared to a N/A motor but still 10K rpm imho should sound darn mean. Just listen to the V6 Turbo's, very mean imo :yes: . Aswell since 'compound turbocharging' is mentioned wouldn't that defeat the purpose of cost savings?

Oh yeah, forgot BMW ran a straight 4. I stand corrected. I am assuming these new engines will be V's though. And by 'crap' i meant quiet! :hehe:

I think that S2000 video might be a fake... no way can you get that pitch by simply changing exhaust.

If they are V4's the cost of all the new development will exceed what FOCA and the FIA are trying to achieve which is saving money. Now if there were any V4's currently on the consumers market I could see it but...

Well since the S2000 originaly had a redline of 9K rpm an extra 1-3K rpm could be extracted with new cams. Does not seem fake to me and about 7-8yr's ago I saw/HEARD a Civic Si that sounded like a F1 engine so the point being who cares what they will sound like as I for one don't watch F1 for the sound, it's just a bonus but irrelevant imho.

I can understand the fuel savings, and the power recovery and everything seems to makes sense for the sport... but given the how checks and balances thing, that sounds like a recipe for disaster... I just don't get it. I'd love to see VWAG in the sport but to limit manpower and development time?!?!

They already have something similar don't they? The idea is to stop one engine getting an advantage, no too different to allowing teams to modify their engines to "catch up".

Yeah but these are engines that have already been developed baked and delivered. These new engines have yet to be designed built and tested... why limit that developement going in. My only thinking is that VWAG feel they'd have a "home court" advantage over the likes of Ferrari and Mercedes as those engines aren't their bread and butter but are much closer to VWAG's domain hence given a shorted time and effort they'd be able to develop a superior design.

I say V's because it means they can basically just chop the current engines in half.

I doubt that Honda is getting past 16k rpm, which it must be doing to get a sound like that. If you don't care about the sounds then why post about them...! :hehe:

True but the cost of redesigning basically the entire engine would not be financially feasable, imo of course.

Actually YOU were the one who mentioned it first :wink:, I was just responding to one of YOUR initial concern's.
