Quote from DejaVu :

Surely a front exhaust will be deemed unsafe, especially during a high speed crash.

A front blown diffuser doesn't mean the exhausts are under the driver or right at the front of the car, it could just mean they are slightly just infront of the engine, which could easily mean they exit near the side, either way, you could create an exhaust pipe that travelled most of the distance under the car, and puncture many holes in it, making it look like a flute, this will drag the car down and give more downward force

Lol, great thing, but... Take your glasses please !

Here is a picture of the R31 this morning from the french website toilef1.com

You see in the rear, under the renault text and under the first golden band, there is a "hole" like for exhausts.

You don't see ? (GreyBull too :P)

Oh, but, yeah ! Maybe... They will redo like last year, they will assemble top developments on the car in the past like for private test or for the first GP...

Wait and see !

I see no obvious exhaust outlet http://img13.imageshack.us/img13/5536/renavale2012.jpg

Perhaps the left side pipe exits rearwards as normal, and the right side one is ducted forward. Although how much of an effect having exhaust pipes of quite different lengths has on engine performance I don't know.

You have to admit that the way the floorpan is shaped, it's starting to look more and more this way, especially in and around the barge board area, it's insanely complex, I go with it that it could be frontally blown.

One exhaust ftw ! :ices_rofl

No, serious.. Mystery !

Scarbs seems to think it's possibly a front blown diffuser system!

Amongst all of this detail no exhaust pipe is apparent, This is clearly one of LRGPs trump cards. I understand the exhaust does not exit at the rear of the car. This leaves few reasonable option for the pipes location. Either above the gearbox or increasingly rumoured the exhaust routes forward and exits in front of the sidepods. I presume the aim if this were the case, would be to pull airflow from under the nose to create some front downforce and speed the flow up back towards the diffuser. We are being told to expect new parts on the car for its first tests. These are apparently both the exhaust and some parts at the rear of the car.

Really? Man these people never stop getting some new stuff are they

Well, it could be all just 'hot air' (PUNNNTASTIC) & in the end and they may have a conventional exhaust system. but clearly Renault are trying something new, and I suspect McLaren might be trying something similar.

skip to around 2:40 to see rear wing flap open and THEN shut. EXCITING STUFF!!!

rear wing talks!

Quote from GreyBull [CHA] :

Quite a detail... But I don't really get why Sauber has kept BMW's colour sheme.

Captain "Pete" likes white, he said.

And you?

First thought: OMG ZOOM We haz $pon$or$!

So far:

The RBR is somewhere I've seen.

Red Bull looks the least changed to me.

But they got a nice rear going I noticed.

Talking of nice rears, Williams just decided to take a chainsaw to the last halve of their car altogether.

Yup. Some pics from today.

RB7 rear end is super tight as expected.

R31's exhausths localised !

I really hope Green Lotus, kicks the ever loving crap out of Black Lotus this year. Unlikely as it may be.

hehe lovin' this. Wonder how hard it will be to copy this system, if of course it'#s proved to be faster.

The Renault must have quite the heat shielding... I wonder if this is really a working system for hot races like Bahrain etc. Guess that was also the first thought the design engineer had so it's probably ok afterall

Anyway, still hoping for that Williams to be actually a decent & fast car. The rear is pretty much not existant, quite a packaging.

What the hell, what happened with the rear-end of these cars?

Presumably with rear blown diffusers out, they are trying to get as much airflow to the diffuser as possible by cutting away as much as they can.

It gets bloody hot everywhere inside the engine cover of an F1 car, so they're used to dealing with heat. The only "cool" place is outside or in the cockpit, and even that can be 50+C.
