The side impact structure is visible in the drawing. 

 

Interesting concept, but I don't think we will see it unless the floor performance is absolutely god tier to make up for the rear wing being completely obstructed. 

And side impact structure is normally quite long for people to want to waste that space not putting sidepods.

Rossi confirms several things that we suspected about RE22.
Good news.

"The engine has been redesigned entirely," Rossi said. "The split turbo is one element. We will [also] make it more compact, which enables us to move it closer to the driver and therefore the centre of gravity of the car.
"It's lighter. It's capable of operating in a much wider range of conditions, temperature and pressure.
"So it's really like a game-changer for us and it's going to, I hope, enable us to catch up and close the gap to the front of the queue [on engine performance]."
The split-turbo design is difficult to achieve because it requires a long connecting rod between the turbo and compressor that runs across the top of the engine and spins at up to 125,000rpm.
Former Alpine non-executive chairman Alain Prost said when he split with the team last month that the engine was having reliability problems on the test bed.
Rossi said the failures were caused by his asking the engine department to push as hard as possible for maximum performance. He said the design was now running reliably in time for the start of pre-season testing next week.
Rossi said: "I told the team: 'You push the envelope far. I don't care. I'd rather have to dial down the performance, but know that I've reached a peak of the performance I can get and then be reliable, than just feel comfortable with a reliable engine that was not delivering the performance.' Which, by the way, was the approach of the past.
"The good news is we've been doing thousands of kilometres with this new power-unit in the last few weeks, and it went just fine.
"So knock on wood it seems we have fixed that."

Do the current rules still mandate the engine air intake be located in the toll hoop?

I love the new philosophy. Performance first, reliability second.

I can't say that I was aware of this being mandated to begin with. I always thought that it was due to it being the result of wanting the most compact solution, with the lowest center of gravity for the engine and it's cooling elements, that desired an airbox as a solution.

I thought it was mandated as part of the 2014 rule set. I would think locates the intake(s) on the sidepod would be optimal aerodynamically but maybe not mechanically.

This Rossi comment is intriguing: "The engine has been redesigned entirely," Rossi said. "The split turbo is one element. We will [also] make it more compact, which enables us to move it closer to the driver and therefore the centre of gravity of the car."

 

A split-turbo à la Mercedes or Honda would, on the contrary, will push the engine back, because when you mount the engine on the monocoque, the compressor and its air ducts and the oil tank will obviously need to be inserted in a recess in the rear bulkhead of the monocoque, and a split-turbo layout will need a bigger recess than a classic Renault layout like in the picture. And that bigger recess will take volume from the fuel tank, so you'll need a virtually bigger fuel tank, and since teams generally prefer to lengthen their fuel tank instead of widening them or making them taller, that would push the engine rearwards...
IMO that's the only advantage of the Renault layout over the split one, the front of the V6 is less crowded and more plain, so it can be pushed forward. That's what Mclaren's technical director said about it in 2018.

 

But the good thing is that the mandatory weight distribution is more rear-biased this year. So pushing the engine a little back shouldn't be a big problem.

 

Unless 
- they have inserted the compressor inside the V, like Honda in 2015-2017...
- made the fuel tank wider

- made the battery (which also need its own recess under the fuel tank) smaller to regain some lost volume...

 

The Renault ES didnt change much shape/size-wise between 2014 and 2018 at least. Maybe the 2022 one is smaller...

 

Or maybe Rossi is just talking about the turbo and its CoG. With a split turbo, the compressor will obviously be closer to the centre of the car, while the turbine will be closer to the engine and closer to the CoG of the car

Looks like a 3d render photoshoped on the racing bays...
Having said that, it seems to have very forward sidepod inlets, like every car this year...
But it seems to have a cape under the nose too...

And the livery makes no sense...

86,23% fake

How is this even possible? "All in" centerline cooling?

If Alpine do this, then the floor will not look like this. It will be perhaps thicker and shaped like up side down wing…

I think the leak is real, nose looks very slim but the livery is hideous. The car will probably look better from all angles in Monday, but jeez.... 

[Ali623]

Definitely fake, lighting of the car is off compared to the environment and the blur was clearly done in post-processing.

[Viryfan]

Fake according to people close to the matter

[ARTGP]

Lol. Here I was getting excited.

I wouldnt mind such a livery; pink, Castrol green and Alpine blue. Could be a pretty livery. Pitty its fake.

What are people expecting from the 2022 car, a Ferrari style out of the box thinking or a Mercedes style polished and matured design?

I'm expecting something that looks very polished, nothing too flashy but very well developed with some drastic early developments in the works for the 2nd test.

From what I've gathered from people involved with Alpine, it sounds like it's going to be quite innovative, at least visually like the Ferrari.

Will it be considered innovative is someone has already released a similar concept before them? The dangers of such a late launch 

[Alburaq]

Since they are supposed to have worked on this car since 3 seasons, I want

- an agressive car made by a team who thoroughly studied the rules, identified every gray area and exploited it

- a team that have tested every possible shaped underbody iteration to find the best one, and designed the car around it.

[Alburaq]

Hi, I'm Matt Harman, the technical director for Alpine F1 Team. This is my wish-list recipe ingredients for a successful car in accordance with El Plan:

 

- a flat/low AoA front wing à la Ferrari, loaded and low at the center section, unloaded at the mid section

- a short nose preferably

 

- the steering arm must be aligned with one of the wishbones, like Mercedes for axample, for clean airflow and look. A slightly offset steering arm to produce downwash would do it too.

- for the floor entries, I ll let the team choose, in accordance with the FW, but the Merc composite geometry is very interesting.

- their sidepod design is great too and it combines the best of both words, big outwash and downwash AND big undercut. --> slim sidpods.

 

 

- no centerline cooling, or a merc style CCS (flat) for a lower center of gravity

- no air-air intercoolers. Water-air

- Merc style exhaust manifolds too, they merge inside the bellhousing and are shrink wrapped around the engine

 

- Pushrods at the rear. They slim down the gearbox bottom, offer more room for the tunnels and clear most of the way towards the diffuser top / or raised pull rods à la... Mercedes

- Inverted bottom rear wishbones too, for the same reasons

I work for nobody. I'm my own boss. : )
Oh I forgot that the nose profile needs to be slimmed down, like Ferrari/Mclaren/Aston Martin

 Strange looking sidepod shape.

[MichaelPM]

Wing mirror inline with front of the sidepods? McLaren-ish

Sidepods taper off dramatically? Mercedes-ish

Front wheels might be very close to the front wing? McLaren-ish

Intake cover drops dramatically but might be thick? Mercedes-ish

Flattish front wing? Mercedes-ish

No halo? Now that's a crazy innovative loophole or it's not a full car underneath so ignore everything else I said.

Halo is definitely there but probably the cloak is slighty more higher so it makes it look like it's not really there. Really excited for the "final" reveal (ahem Red Bull), I think they will probably go Mercedes path(safer way) but do have high hopes that they will battle with Mclaren for 4th and be on podium multiple times. Let's see!

[w1Y]

Is that a high centre nose?

[Alburaq]

Green area looks like an air-filter compartment to me, so I guess the blue area is the compressor duct, while pink duct should be feeding a radiator behind the engine... Is the roll-hoop painted black?

So this roll-hoop ducting looks similar to the Mercedes teams ducting
