All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

people say (eg of bicycle hub gears) that epicyclics don't allow ratios close to unity (unless multiple stages are used)

Listening to Ross and Jean over the last 2 weeks on the future of engines, few things are clear

1) NA is not happening
2) They want more involvement of manufacturers but at a accessible cost
3) They want to continue parts of the existing technology

On the other hand we have Liberty's idea of close competition but reduced cost.

I think going into the next generation of engines are going to have some form of BOP for manufacturers to enter without a huge cost

What I would like to see (totally wishful)

1) A cap on the energy recovery to be set at either 4 or 6 MJ and do away with unlimited recovery
2) Cap on the ICE engine power at 1000 HP
3) Fuel flow of 100kg/hr and fuel ration for 105kg per race removed
4) V6 and single turbo stay

Existing manufacturers would have an advantage of fuel efficiency, but incoming manufacturers would not be would not bee too handicapped as the difference in the fuel weight is not going to be massive.

to be fair i think it might go like the old days..
1.5 turbo or 3.5 litre and you can have any NA config...

for sure it will be more in line with today engines so 1.6 turbo hybrid or cheaper 3.0 litre hybrid to be on power balance..

for sure weight is going to be something to choose but if they want they can make rules to compensate for performance with that... giving an edge in weight for the NA hybrids due to less torque.. etc.. but an offset mid race as they have less weight form less batteries, turbos etc... so could be interting formula.. we get sound.. that we all want.. cheap engines for some, and keep the big boys happy with the current engine regs on the other side...

it allows to have expensive engines or road relevant tech, for some teams,, but it allows for smaller teams to have cheap engines like the V8 hybrid era, and for us.. great sound and a way for a manufacture like Honda if they want to make a getaway to a more simple engine for 2020 afterwards...

wold be fun to see what wold win, also they wold have very different car designs so.. i think it wold be for us very entertaining... and even for them... it wold mix it all up....and everyone got what they wanted

Somehow don't know if 1000HP turbo can keep up with a 1000HP V10

Let us see...
V10 car, 595 kgs + 200 kgs of fuel = 795 kgs
V6 turbo car, 720 kgs + 105 kgs of fuel = 825 kgs
V10 car will have a huge advantage after 25% race distance

From the looks of it the manufacturers will shy away because the V10s will win but will not use as it is not road relevant

People still think that the V8s and V10s were cheap. They absolutely were not.

The V8s were "cheap" because their price was capped by the FIA.

You cap the power by using a fuel flow rate.

There seems to be an opinion that the MGUH will go for the next formula. In that case I would consider getting rid of ERS altogether. Save some weight and have ~800hp V6Ts (100kg/h) or maybe have more power by upping the fuel flow rate.

As long as the MGUH is there I vote to allow it to have unlimited recovery.

Fuel flow rate is fair and then there is no need for balance of performance.

If you cap power with fuel flow rate then cost goes up. It is better to just cap the power with BOP without fuel restrictions so that the cost comes down for new entrants.

The benchmark for efficiency has already been set close to 50%, existing players will have the advantage of starting the race with lesser fuel, new manufacturers can either try getting close to that or just play the marketing game without massive consequences.

well that might be the good think to have the v6 start better and the v8 v10 mid race be lighter and have an advantage.. also, the v8 is a third more affordable than the current engines.. Well this fixes the problem, if a manufacture wants to have a ´´road relevant ´´v6 turbo hybrid good.. if someone wants a cheap v8 or v10 hybrid were performance is similar better yet.. let the ones who want to be road relevante be.. and the other use better sounding engines at a third of the price... everyone's happy from the Top teams to the small teams... might end up a very interesting championship this way...

also the v8 for example even with kers did not have 1000hp... so... i guess if it weighs less. but has a bit more power and more than the 6 second kers... then i think it will match like very nicely... no huge development cost is needed for the v8 hybrid... as its already there... some updates and now with bigger capacity battery and recovery .. i think it wold be very good for the sport, for the fans, for everyone really...

The V8s were "cheap" because their price was capped by the FIA.
The last of the v8's were relative cheap because they were frozen and heavily limited (at 18.000 rpm). The biggest costs problem is the size of the corporations behind some (well, actually just one) team. Daimler. You just can't compete against their bankroll, engineering power and resources. If the whole car would be FIA supplied except the mirrors, they would engineer 500mln dollars worth or mirrors made and calculated by 1000 engineers. Cutting costs or make F1 available again for other then big money is standerize certain components like the combustion chaimber and the fuel injection system. That way a company like Cosworth could build a straight forward V6, hook up a turbo, a ERS packet from Magnetti and a Samsung ES slab and you're in.

How about forcing the bigger teams to aid the smaller ones....somehow?

As for PU's, i'm pretty boring,i'd like to keep these units and just keep lowering the fuel flow rate(and displacement if necessary) and allowing more electrical deployment so they stay around the 1000 Hp mark. (yes that's a magic number for me.)

The chassis guys still want a V engine and the car manufacturers seem to love hybrids nowadays so i think this formula is actually pretty good, and remember, regulation changes are expensive for the teams.

I'd actually like to see some guarantee towards the teams that the regulations(all of them, including aero) stay frozen for a number of years, that way smaller teams will be less scared to invest more money into their car.

Alternatively they could start talking to the big automotive groups and ask them "what rules would make YOU want to enter F1 ?".

Hmmn, it would seem that the following statement confirms my initial suspicion that Brawn would be re-writing the rule book, regardless of who he works for:

"Brawn also explained that he wants to hire a team of engineers that he would task with creating F1’s new technical rules, which have previously been drafted from suggestions from the teams and agreed by the F1 Strategy Group and F1 Commission before being formalised by the FIA.
He said: “My plan is to build a small group of engineers and specialists who will be working under my direction and our task will be to try and bring a bit more logic and application to where the sport should head.”

My opinion of the ditching of the MGU-H for the next formula now has slightly more substance, but let's face it, we're all guessing...

I'm not sure how well TJI will work with an un-blown ICE, but direct injection is a must and Brawn will certainly push for V8. He now has a reason to insist that the aesthetics of the 'show' be addressed as well as seeking technical innovation.
So, ERS will stay, but recovery will be difficult without the MGU-H, so, how about a 2.0L TJI NA V8 with 120kW MGU-K (that has unlimited recovery but 8MJ per lap deployment, plus a GU-H that can recover under engine braking conditions?

Keep the 105kg fuel total and the 100kg/hr fuel flow rate. After that you can use any engine layout you like with any ers you can imagine. That's what I want to see.

Total fuel and rate of flow are a pretty good way of achieving balance of power as you're giving the engineers a fixed amount of energy (other than fuel suppliers finding efficiencies).

Brawn must also realize that he is working in the wrong organisation for that.

If they get rid of the strategy group then the FIA will free to write the rules as they see fit.

And that's how it should be - the CRH should have no input into the rules process if the FIA has no input on the commercial side.

I can see your point of view, but that is not Brawn's management style. He always wants his team to win, his way, at all costs. Win is not even the right word, dominate is more appropriate, preferably with an unfair but completely legal advantage.
His 'team' is now Formula 1 and, as has happened previously, he has walked into an under-performing organisation with the aim of making it the best performing organisation. He's a long-term strategist with the patience and presence to ensure the outcome he wants. I have very little doubt that he will get everything he wants (as far as technical control of the regulations of the sport goes) because his new bosses want the same outcome, total domination.

I'm sure the first item on the agenda from his superiors is: 'What can we do about the sound?' Brawn's response: 'Give me control of the technical specifications and I'll make F1 loud again'.
