2014-2020 Formula One 1.6l V6 turbo engine formula

[bonjon1979]

The first thing I notice about the Renault picture is that the exhaust pipe is non compliant, because:

It doesn't have a straight section of 150mm
It isn't anywhere near long enough - the exhaust pipe must extend to a point 170-185mm behind the rear axle line

That's just where the exhaust exits the engine, a pipe will be attached to it taking it beyond the rear axle. Personally, I don't believe anything about the exhausts. don't think they'll look like that at all. Just smoke and mirrors...

SPECULATIONS ALERT! Michael Schmidt (Auto Motor und Sport) on issues with 2014 powertrains

It is said,

• Ferrari has problem with the fuel consumption
  At the beginning of the year during a meeting of the Powertrain Working Group, Ferrari had suggested to raise the race fuel consumption limit from 100 to 110 kilograms. Of course, it was rejected as there is a fuel consumption descalator built into the regulatory roadmap that will require the teams to deliver competitive racing with less fuel each year thereafter.
• 2014 powertrains are not reliable enough
  No unit made more than 3,000 kilometres during trial runs. While Rob White (Renault Sport F1) believes 3,600 kilometres would be enough, Mercedes reportedly set 5,000 kilometres as a benchmark.
  Problem is not with the internal combustion engine itself, but especially with the turbocharger. For example, "a crack in the exhaust may damage the turbine, whereas at the today's engine, only the sound changed," explains White.
  Mercedes also concerns about the "highly complicated" energy storage (ES). "Battery consists of 170 cells, if it is not assembled correctly, the same thing as with the Boeing Dreamliner could happen," says Niki Lauda.
• Will we see huge power differences between qualifying and race like in the old turbo days?
  Niki Lauda: "I assume that the power difference will be more like 10 than 100HP. In terms of the reliability, it is better to run the engine at as constant as possible operating conditions."

Well, yeah, Lauda is not an engineer and sorry if this add nothing to the discussion, but maybe it can give some insight into what happens behind closed doors...

Ferrari has problem with the fuel consumption - could this be where the 100bhp less thing comes from (tbh i don't know about engines so its just a guess) could they be having to sacrifice power for consumption?

2014 powertrains are not reliable enough - will define 2014 season

Renault posted this image a few months back, don't know whether someone had posted it here yet.

But it seems this is how their engines will sit in the RBR, STR...and possibly Lotus' cars:

That pic was already posted before and is not representative, but after 282 pages who can blame you!
If you look carefully, the current Coanda exhaust ramps are still there. It is just a quick photoshop as a rough example. For illustration purposes only.

Not by 100hp, it's too much.

SPECULATIONS ALERT!

Great prefix!
It is that time of the year where it's good to keep sensational headlines without much proof. Even if this is the case, it is still way too early to judge anything and draw conclusions.

My personal armchair thoughts are mostly related to reliability. Put quite simply, I think the target for the engines and the subsequent penalties for parts replacements are too severe. For a starting season. Based on that, until all engines and supporting components are made reliable, we are going to see a lot of unrest.

this is why i said the 2014 will be defined by this. I think they are trying to change too much to soon, the engine limit per season should of remained the same next year, then start reducing in from 2015 onwards.

[dren]

The engineers will make it work.

[piast9]

Eventually they will. I am sure of it that 2014 will be the reliability championship. Which is good I think. I'd like the engineers working on the vehicles to work correctly than fiddling with fine details. I'd also enjoy more smoking engines, broken gearboxes, grid penalties etc as they liven the show. Look how much spectacle the top drivers can give if they are placed out of the regular pecking order.

Interview with Rob White on 2014 - http://www.auto-motor-und-sport.de/form ... 21477.html

Look like my power estimate of 580hp for the internal combustion engine was in the ball park.
I just couldn't see more being squeezed from the fuel. In fact I should have run the engine at th API standard temperature of 60*F and see what increase I could muster from my simulator.

Over 800Hp for the energy unit was a bit too much IMO.

[xpensive]

I believe most of us could see that an efficiency of 35% was as much as could be xpected, meaning some 600 Hp.

Adding the 160 Hp from the MGU and you have pretty much the power of today's V8s.

Surely the mass-flow limit of 27.8 g/s was selected with that in mind?

[Holm86]

Looks like Rob White agrees with me that not every gear will be used at every track.

[SectorOne]

Could you use one gear as fuel saving gear?
Like if you hit top speed in 7th, flick in 8th and it stays at top speed but rpm drops.
Or maybe that makes no difference?

If it's top speed you are on the engine top power spot. If you shift out of that gear you will have less power and speed will drop.
