that pic from Apr 4 is very good...you can see the leadscrew on the inerter....

What are all those electronics on the front hub? The rules stipulate that braking must be purely mechanical... just sensors?

That would be my guess.

My guess as well.

Theres probably arround 10 diffrent things they monitor on each wheel, like:

Core Wheel RPM
Brake Temprature Inner Disc
Brake Temprature Middle Disc
Brake Temprature Outer Disc
Brake pressure
Air Cooling Volume
Air Cooling Temprature
Ammount of useable brake left avalable (Ware rate essencially)

Thats 8, but im shure theres more, anything that the team think they can analyse to help the set up the car or improve something, it will be recorded. Theres no such thing as too much data.

I'm not sure why people are noticing the triple "deck" of Toyota's diffuser only now. They've experimented with the triple deck on their diffuser early in winter testing. In testing they were even sometimes running it asymmetrically with the third deck only on one side of the diffuser.

Got a picture of that?

as scarbs pointed out, they have been using the so called "triple-deck"diffuser since Jan in winter testing. here are some a image of it and F1.com description. however they are incorrect in believe such development was introduced in the Malaysian grand prix, as this was not the case.

I wonder if they take all that crap all the car for the race... lower the unsprung weight... its not like they can change much of any of those parameters during the race.

Here (contrast-enhanced to show third deck):


You can see to the left of the crash structure the third deck element is there, but it's not on the right side. This was in early March testing at Jerez, Toyota experimenting with assymetrical diffuser set-ups.

new rear diffuser, double deck part looks wider.

[vasia]

Very interesting, that is indeed a new diffuser. Toyota's development pace seems to be very strong so far, they've already changed or updated their diffuser twice since the beginning of the season. Toyota, despite starting the season with a DDD, is still continually updating and evolving their rear diffuser. So much for the belief that the non-DDD teams would have greater scope of development.

My first instinct is also to want these removed because on the surface, they are not necessary for the actual race. But the parameters they monitor are also directly applicable to the race. For instance, brake temperature is important, and I have frequently heard engineers telling the drivers to maintain brake temperature.. because the sensors indicate lower than optimum temperatures.
And history has proven that sometimes alloing the engineers instant data allows them to bring the car home, despite problems it may have. The engine is running hot, lower the rev limit, things like that.

Look at those two holes on each corner near top side of the nose. I guess they are the cool quick release clips for the noses. Can anyone confirm? It seems like a nose can just be pushed into place and thats it.

They will probably have at least one guy watching all that crap for each car in the back of the garrage somewhere. I just dont for the love of me cant see why they would need so many sensors myself. Maybes its worth something for they guys that play with the windmills and with computers back at base.

Shurly in the age of cost cutting, some of this could be cut back. Once standrd telemetry and data gathering systems get introduced the better. it means all that extra weight can be put into the car as balast, whitch arguably is more of a advantage.

And there is also an electrical recepticle between the upper elements that guide and align the nose structure. I must assume it's for the front wing electrics, although I never anticipated it could be that type of connector.
The requirement for some form of electrical connector between the tub and nose srtucture makes it necessary (for this kind of connector) for the nose structure to be slid in neatly from the front. So it appears the requirement for this kind of handing for the nose drove the development of the cool trolly used to affix a new nose structure.
