February 19, 2016, Ferrari has announced the 2016 fiscal machine "SF16-H".
The appearance of this new car, please refer to the F1 Tsushin.
A result that saw the shape of the machine, and then wrote my opinion.


The biggest difference between last year, return front suspension to the push rod, but that the nose has been shortened.
Pull rod does not mean the suspension performance is inferior than the push rod.
However, in order to high foot box and packaging, push rod is the convenient.

Upon a short nose, and to interpret the regulation as it is, and this form. (2015 F1 image of the body work of the Technical Regulation.)
By the higher the tip of the nose, air flow go to the bottom of the vehicle body, a larger amount.
As a result, the down force obtained by the vehicle body underside would be up.

Then, looking at the angle of the front wishbone from before ...,
Toward from the vehicle body side to the wheel, the arm is lowered angle becomes weak, the roll center of the front is lower.
This result, limit speed of cornering might be improved.

The concept of the front wing, but the current standard.
Flap has become a angle to retreat toward the outside.
From this, the air in the wing upper surface, toward the outside of the front wheel.

When viewed from the front, the bottom surface of the end plate of the front wing, the double tunnel exterior and interior are provided.
This structure, low pressure wing lower surface, have addressed airflow sucked from the outside of the wing.
The under wing, splitter of the left and right three at a time has worn equipped, has been the consideration of detailed aerodynamics.

The front wing of the cascade, there is a splitter of the three pieces.
By these contrivances, the front-end air, are actively flow to the outside of the vehicle body.
In this case, the air flow of the cascade top surface, over the top of the splitter, but swirling involving,
As a whole, it is possible to flow the air to the front wheels of the outer.


The structure of the side deflector has a four by the sum of the left and right. The main of the plate, but the gap flap.
Gap flap, cast a strong high-pressure energy from the gap to the back, to prevent the peeling of the deflector inside airflow.

The maximum height of the side pod is high.
As a result, from the separator of foot box under side, it flows through many air to undercut side pod.
This is the body the lower surface of the low pressure, to reduce that to inhale the lateral side of the air.

Body lower surface, aerodynamic performance is further improved when the air is passed through from the front linearly backward.

Looking at the side pod, the starting point of the Coke bottle line is in front closer.
From this fact, can be seen with the rear end is narrow.

Side pod top surface is in gently dropped towards the rear.
This is a rear wing and together to form a curved surface recessed. A result, to generate a positive pressure of the trace.

Both ends of the side pod is a small bulge. Inside the body, probably extending the crushable Structure here.
Bulge is, if this extent size, do not give a little effect on the aerodynamics.

Although L-shaped vane surrounds the front of the side pod, which is, to purify the turbulence that the front wheel is stir up.
In addition, the upper side of the horizontal vanes, cross-section is different on the inside and outside.
This has two reasons.
(1) The upper edge of the side pod because of the shape to flow to the top of the air, the inside of the vane there is a need in the form that flipped up.
(2) The inner and outer vane, the clearance between the side pods are different. Towards the outside it is far away.

Regulation of the side protector is updated, the height is raised 20mm.
In the outside, it is made to discharge the heat in many of the louver-slit.

The induction pod, wearing the mini wing was tilted backward.
This, Drag generated in the roll hoop camera, there is likely to be prevented from becoming a simple loss.
In BAR and the same philosophy in 2004, probably the forward flap of the rear wing.

The rear of the side pod, after narrowing the top surface once, spread then also.
1994 Arrows were these shape.
In the lower part thereof, we are narrowing the coke bottle line.
This is, to a very excellent aerodynamics of the rear end.

Of SF16-H, the side pod and the rear suspension arm are excellence in packaging.
Here, if, if you lower the cowl without well thought out, to expose the upper arm, in the way the air flow of the rear wing.
And the point to sink the cowl, or angle, and the like to the quantity, various designs are contemplated.

Transmission is going are the same as last year, made eight forward speeds and one reverse one of the gear.

End plate of the rear wing, slit on the front side there is one by two left and right.
This probably reduces the occurrence of the boundary layer, either would not than has to activate the wing lower surface of the air flow.

The rear of the end plates, fin is there one by three, this effort, are going to get even a small achievement.


Last year, Ferrari became the second place in the constructors'.
With the goal of overthrow of the Mercedes too fast, SF16-H is understood to have carried out an ambitious development, it is the machine that likable.
Undoubtedly, would have stepped on the step of the next stage.
Similar to the chassis, is caused to expect that also advances the power unit.

The driver will continue, but the world champion duo of Sebastian Vettel and Kimi Raikkonen.

It should be noted that, Jock Clear has joined as director of race engineering from this year.
He had served as a performance engineer of Lewis Hamilton in the Mercedes until 2014, but left the Mercedes, so far has been spent gardening vacation of one year.
