I think you will have less drag from having shorter sidepods.
Simon: Nils? You can close in now. Nils?
John McClane: [on the guard's phone] Attention! Attention! Nils is dead! I repeat, Nils is dead, ----head. So's his pal, and those four guys from the East German All-Stars, your boys at the bank? They're gonna be a little late.
Simon: [on the phone] John... in the back of the truck you're driving, there's $13 billon dollars worth in gold bullion. I wonder would a deal be out of the question?
John McClane: [on the phone] Yeah, I got a deal for you. Come out from that rock you're hiding under, and I'll drive this truck up your ass.

...and more efficient diffuser area I think. i.e. more rear downforce.

It seems that with the new design, air will be channeled either over the sidepod or into the radiator duct. I think with the old design, some air would be pushed to the sides.

In addition to aero, there will also be some minor weight savings. It is carbon fibre but the centre of gravity and weight balance will be affected... all
other things being equal (i.e. ballast or other internal changes).

I agree with hatchet man on the airflow with the new sidepods, does look like it is a more 'traditional' looking radiator inlet (i.e. scoop rather than streamlined). Possibly they were having some cooling issues?

That engine cover should give them some extra straight-line stability, especially in any kind of crosswind because it would push the rear out and point the nose into the crosswind, minimizing crosswind sensitivity. I really like these detail changes, it means the engineers are working hard to squeeze every last bit out.
I love to love Senna.

Looks like McLaren made exactly the same move as Ferrari developing their sidepods.

PS: anyone got a better picture of this?

Pretty big sidepod change for that MP4-22 there.

I cannot see any slot gap protector on Ferrari's rear wing.

Also $10 a Merc goes up in smoke.

Or.. maybe they have found a way to maintain air pressure coming inside the duct?

I read somewhere that there are 15 cooling slits on each side, wow. Can you see the "thermometers" in between each slit?

I think this is the first time I've seen an Exhaust Gas Temperature sensor on the Ferrari, they must be tweaking the car for lean fuel burning.

I think this is a nice detail of the rear flow conditioner.

Thats a lambda sensor:
An automotive oxygen sensor, also known as an O2 sensor, lambda probe, lambda sensor, lambda sond or EGO (exhaust gas oxygen) sensor, is a small sensor inserted into the exhaust system of a petrol engine to measure the concentration of oxygen remaining in the exhaust gas to allow an electronic control unit (ECU) to control the efficiency of the combustion process in the engine. In most modern automobiles, these sensors are attached to the engine's exhaust manifold to determine whether the mixture of air and gasoline going into the engine is rich (too much fuel) or lean (too little fuel).
You got the right idea but it doesn't measure temperature. I'm sure F1 cars have all had these on since the 80s.

who knows what's that little pipe next the lambda sensor?

what about the one right next to the 02 sensors looks like maybe a thermo couple for measuring egt

More likely to be measuring pressure, temperature in the exhaust can be found out from the pressure and exhaust pressure plays a huge part in engine performance.

Could you please explain it? :)

Pressure and Temperature are proportional.

And a few more things :p

but all in all, given the conditions, they could work out the temperature :)
