Ferrari F14T

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter do not belong here.

And in that case, you do blip the engine with fuel and not with the ES energy.
If you are aiming at max performance yes, if you are aiming at max efficiency no.
Agreed. And you'll aim to maximal performance if you don't have to look for maximum efficiency.

Say in qualifying.
Or at tracks with inherently low consumption.
Or if you 'd like to push hard for some laps.

Will be interesting whether Ferrari will have both options available to the drivers, according to the actual "performance demand".

Maybe this Ferrari trick is a creative and effective way to resolve an overcharge situation by exhausting the electrical overage through driving the crank--which also aids in gear shifting, fuel saving, engine heat generation...
I like that notion. Perhaps they faced those problems too and decided to "waste" inconsistent energy output to avoid bateries having reliability issues. What if there is not a reliable energy storage solution for the amount of power these power units can develop in an advantegeous packaging configuration? If you think you can, with time, maximize this power unit & package spec within the season... then find a bypass.

Even if your system can work with "normal" downshifting, implementing this solution could be very interesting during the season, used during extensive moments on sundays, given the amount of stress these power units will endure it can be a wise strategic choice.

Not only the fuel consumption could be improved (I don't believe this is the main reason, as normal ICE downshifting should'nt be done with the same amount of fuel as regular acceleration), but engine could benefit from a small pause when breaking, which is always a good.

Taking a different point of view, even driveability can suffer interesting changes. Perhaps the pilots are going to see advantages in that, who knows.

Anyway, I don't have the tehcnical insight to know, nor want to have it. Please feel free to consider this post as bullshit, or related to something that was discussed in some obscure thread.

If the port injector is not injecting fuel, you ain't burning it. It is also very normal to be using the MGU-K under braking since that's its' primary use.

The term "doppietta elettrica" or double electrical suggests to me that they believe Ferrari are some how using both MGUs under braking to charge the batteries and by passing the engine.
I think the term is more due to the mgu-h spinning up the turbo, while the mgu-k is harvesting.

I thought that was a way of cooling the engine ?

The term "doppietta" means double declutching. In Italian is the technique you use to drive cars with Non-synchronous transmission (i.e. older model of Fiat 500). They just blip the engine rev up with the MGU-K on gear downshift.

Thx, stand corrected!

Watch the video closely (1080p HD in full-screen mode) and see lots of images, including CAD of the front wing mounting, turbocharcher, etc.
Screengrabs are already flooding Twitter.

Wow, apparently it's too early in the morning for me. I stared and stared at this going "wow, what's that part with the 2 big jagged cuts in it!

We all had that situation. For me it's a clear case of "optical effects when looking at upgrades due to lack of coffee".


It usually worsens on fridays. A lot.

Ok, for fun I will give you the exact operation implied as I had to learn doing the "doppietta" when in Rome, a long time ago and under age, I used to steal my aunt's Fiat 500 to go to my tennis club (I hated the bus!).

If you need to downshift say from 3d to 2nd gear, you will need to (a) with clutch down go from 3nd to neutral (b) while in neutral, release the clutch and bring rpm up with a good push on accelerator and (b) clutch down again to insert 2nd gear.

And that is what the doppietta is. It seems to me it has nothing to do with what is reported on Autosprint. And it is only related to the heel/toe technique because such technique is required if one is both downshifting and breaking at the same time in a car that requires the doppietta.

What do you mean? The nearly rectangular holes?
Undercut should be like in Bahrain.

Yea, because to me that looks like the foam insert that goes around the driver setting in-front of another part.

First shot of the F14T minus the engine cover. Not much detail shown thought. Based on the angle this must have been taken by someone in the Ferrari box. Looks like the launch spec rear wing is on the car, not the later one used at the final test.

On F1 car the sequential transmission is non-synchronous so on down shift the electronic do a sort of "doppietta" to match up engine rev with transmission rev on new gear. On the Ferrari engine this task is performed only by the MGU-K while on other cars is performed by the thermal engine itself.
