February 22, 2018, Ferrari announced the 2018 machine [SF 71 H].
For an overview of [SF 71 H], see F1-Gete.com.
Then, I will write my opinion from the picture of the car body.

The inner section of the front wing was a gap flap type, totaling 7 solutions.
In particular, it has seven specifications to prevent airflow separation on the lower surface of the wing of the flap inner area where the angle of attack suddenly rises.
Since the air current flows from a place with high pressure to a place with low pressure, guiding the high pressure flow on the upper face of the wing to the lower face of the wing is effective in preventing peeling of the air current on the lower face of the wing.

The nose tip has passed the technical regulation by providing protrusions in the center.
Both sides of the protrusion designed the lower surface of the nose high, now standard F1 design. (Except Mercedes.)
The tip of the protrusion is a shape that can lead even more air currents to the left and right than last year.
By doing this, we supply as much airflow as possible to the bottom of the car body.
There is a small hole at the tip of the protrusion, but it may be the purpose of cooling the front suspension damper or the driver.

Like the McLaren of last year, the nose · stay is a longitudinal clearance flap type, inhaling the airflow inside.
This opinion is divided depending on whether to inhale the air current to stay in stay or discharge to the out.
[SF71H] supplies the air flow as much as possible to the lower part of the body as the former.

The existence of the nose hole can be confirmed by photograph from the upper surface of the car body.

The front suspension did not become a high mount Wishbone like Mercedes. It is a surprising event for me.

Canard, extending from the monocoque side to the side, is a simple but effective shape.
This canard directs the airflow which the front wing once jumped upward.
Considering the shape of the under plate projected downwards, it can be said that it is a good canard shape.

Side deflectors and side vanes are simple shapes and may be specs for recital.

The air intake of the side pod which is drawing attention is partitioned by a cowl.
Two intakes in front and one in the top.
Regarding this area, I will write my opinion after confirming more pictures at a later date.

[Halo] obliged from this year, you can see protrusions like gurney flaps at the rear end of its upper face.
This is a vortex generator, which alleviates large peeling of halo wake.

The second half of the side pod, like Red Bull and Mercedes, became very tight.
The bottom of the coke bottle line is narrow and the top is wide.
The former is to supply a fast and clean air current to the diffuser, the latter is the opening amount necessary for exhausting the side pod.

With the remnant of last year's [T Wing] regulation, [gearbox · wing] will be popular this season.
[SF 71 H] makes the gearbox wing shape wing curved downward.
This [middle T wing] seems to be in charge of collaboration between the high pressure flow on the upper side pod and the low pressure flow on the lower side of the rear wing slightly away from it.

The rear wing stay is also two in this year, and it prevents the rear wing main body from being shaken by the vibration during running rather than the reduction of the air resistance.

Especially this year's Ferrari will have an update by the opening race so the evaluation of the chassis will be kept waiting until the opening race.
The same driver as last year, the combination of Sebastian Vettel and Kimi Raikkonen.
