Scuderia Ferrari SF15-T

Could it also for example be like:

13500 rpm = 100kg/h
12500 rpm = 95kg/h
11500 rpm = 90kg/h
10500 rpm = 85kg/h
etc..

In this situation you still have more power at higher revs right?

Why would you do that? You'd be just leaving things on the table that way.

Possibly to use shorter gears for faster acceleration?
Or am I completely wrong.. ?

Gear choice is consequnce of engine characteristics. If engine's peak power is at X rpm you always want to be as close to it as possible, that's pretty much all about gear choice. If engine doesn't want to rev (e.g. some diesels just start to drop off above a certain revs) it's pointless to use shorter gears.

No offence, but yeah.

Fuel use would be the same; 100kg/h. Because of that, power should stay close to constant as revs build and assuming the AFR doesn't richen to help lower exhaust temperatures. However; if power is holding steady across the 10,500 to 15,000 RPM range, torque would be linearly decreasing across the same band.

I do know know whether the lower torque of over-revving a lower gear would offset the addition mechanical torque multiplication of being in a lower gear though.

Fuel use would be the same after 10500, yes. That's why he was told to use higher gears, so he's below 10.5k for more of the time.

13500 rpm = 100kg/h
12500 rpm = 95kg/h

The regulations state that 10,500 rpm is the point of max fuel flow. That's how everyone knew that the 15,000 RPM limit silly because no team would need to go over ~12,500 rpm.

Ghe ghe.. I appreciate your honesty!

Do people even read threads?

The Ferrari aerodynamic philosophy is not really different than last year I feel. For example, the front wing resembles that of last year. There is only few reliefs at the ends of the wing unlike others teams as RBR or Mercedes...

Sidepods are also differents than others cars. Indeed, the sidepods of Ferrari SF15-T have stranges shapes when you look at the car above. The Ferari have triangular shape contrary to RB11 or W06 who have a "gothic" shape (gothic is the adjective that describes Concorde wings. This adjective was created by aerodynamist who work on this plane ;D )

In fact, if Ferari has made progress, it's not on aerodynamics because we can't see many changes from F14-T

Different side pod shape, different cooling exits and horizontal louvers at the bottom of the rear wing endplate to name a few aero changes.

No, just have a look on F14-T and SF15-t and you will see that side pods shapes are the same. After that, have a look to MP4-30 or RB 11 above and look who narrow are sidepods. Ok, cooling exits are a little closer than last year but it's not as significant than on the Lotus for example.To finish, horizontal louvers are a detail of aerodynamic and this probably not going to give them a big advantage I think.

Also total new diffuser and its side panels around rear tire, new tire squirt cutouts. That is quite significant change in rear design philosophy.

Plus new front pullrod "Y wishbone" and hidden trackrod layout. If you put all together it is quite a step foward. I will say normal evolution of the car. In 70s this car will definitely get the F14T-B mark.

- smallest sidepoids in the field.

I didn't understand this?? SF15-T does not have the smallest sidepod.

Well if you have a look at this picture you can see that Ferrari's sidepods/rear end packaging is at least on par with Mercedes if not even better

The image proves they are not as tight as the merc.
It pokes out on the sides and has much more volume further back.
Thanks to Crucial Extreme that set the record straight, being a misinterpretation.

Actually what makes them "poke out" is a cut right after the edge of the radiator. I guess total volume is similar. It would be interesting to see the internals.

Front wing has nothing to do with last year's one. Has 8 layers on the external sides. No other car has so many. Just check Scarb's analysis on Peter Windsor's Youtube channel
