Aerodynamic Brilliance
Uncover the aerodynamic mastery that defines the Ferrari SF90 XX. From sleek lines to innovative downforce mechanisms, every element is meticulously designed to enhance stability and handling at high speeds.
- The nose part of SF90XX (bottom) is different from SF90 Stradale (top). You can see that the SF90XX has a flat floor because the air that enters from the front escapes through the bonnet duct at the top. By equipping it with S-duct, it not only improves cooling performance but also increases downforce.
- It is clear that the SF90XX (right) has better front-to-rear balance compared to the SF90 Stradale (left), which has a lot of lift at the bottom of the front.
- The large rear wing and the adjustable shut-off gurney located below it also contribute greatly to aerodynamic performance.
There is no doubt that the biggest feature of the SF90XX Stradale (hereinafter referred to as SF90XX) is its aerodynamics. The symbol of this is the independent wing that towers over the rear end of the body.
Ferrari has not used an independent rear wing on its road cars since the F50, which was released in 1995, because it “detracted from the beauty of the design.” However, the SF90XX inherits the philosophy of the XX model, which was developed for circuit driving, and is purposely equipped with an independent rear wing even though it is a model that can be driven on public roads.
You may be asking, “So what were the claims made so far?” However, independent rear wings have the clear advantage of “improving aerodynamic efficiency.” In other words, this independent rear wing has the effect of minimizing the increase in air resistance while generating 530 kg of downforce at 250 km/h, comparable to that of a racing car.
Furthermore, following the SF90, it is equipped with a shut-off gurney. This allows you to select high downforce or low downforce settings by moving the body panel located directly below the rear wing up and down. The position of the shut-off gurney is automatically controlled by the on-board computer.
In order to balance the increased rear downforce created by the independent rear wing, an S-duct was newly installed at the front of the car. This creates downforce by drawing in air from the front of the car and exhausting it upward through the front bonnet.
Although it does not have a variable mechanism like a shut-off gurney, it is possible to always obtain optimal aerodynamic characteristics by devising the shape of the internal duct. The louvers on the front and rear fenders are also unique to the SF90XX and not found on the SF90. This allows the air inside the wheel house to escape to the top, thereby preventing the increase in air resistance caused by tire rotation.
Backing of the technology that delivers 1030PS :POWERTRAIN
The SF90XX uses a plug-in hybrid powertrain, but the source of its power is a 3990cc V8 twin-turbo engine named F154FB. This is based on the F154FA installed in the SF90 Stradale (SF90), but in addition to polishing the inside of the intake and exhaust manifold, the top of the piston was changed to increase the compression ratio from 9.5:1 to 9.54:1. It produces 797PS at 7900rpm, which is 17PS more than SF90. The maximum torque generated at 6250 rpm is 804 Nm, and the maximum rotation speed is announced to be 8000 rpm.
It is also noteworthy that the weight was reduced by 3.5 kg by omitting the secondary air system that was attached to the intake system. Furthermore, to improve engine sound, the hot tube system that transmits engine sound to the cabin has been optimized.
The tone has been changed to emphasize the treble. Like the SF90, the SF90XX will have two electric motors, one between the engine and gearbox and two on the front axle. However, the maximum output was increased from 220PS to 233PS by using extra boost, which will be explained in a separate section.
It goes without saying that the two motors installed on the front axle control the distribution of driving force between the left and right sides to achieve torque vectoring. In addition, the hybrid system can be selected from four modes: e-Drive, Hybrid, Performance, and Qualify by operating the e-Manettino. The battery capacity is 7.9kWh, which allows EV driving of up to 25km, and the maximum speed when driving in EV is 135km/h, which is similar to SF90.
The gearbox is basically the same 8-speed DCT as the SF90. However, by improving the software that controls gear shifting, you will be able to enjoy the feeling of “the car being pushed forward” similar to the Daytona SP3 when shifting, and you will also be able to enjoy a dynamic sound when shifting in the mid-to-high rpm range.
Pursuing the thrill of driving
As befits Ferrari’s latest model, the SF90XX is loaded with the company’s proud electronic control systems. First of all, I would like to pay attention to the extra boost. By increasing the cooling capacity of the hybrid system, the SF90XX temporarily succeeded in drawing out more electrical energy than the SF90. Extra Boost utilizes this to improve performance.
Extra Boost can only be used if the battery has enough energy stored and the onboard computer determines that it can provide additional power based on GPS, accelerometer, pedal effort, etc.
The operation is simple: once you select Qualify mode on the e-Manettino, the system automatically finds the optimal situation and adds about 2 seconds of “extra power”, mainly for exiting corners. There was no specific explanation as to how much PS this extra power is equivalent to, but based on the charts and other information released, it seems to be around 200PS.
Another piece of news is that the SF90 is equipped with ABS evo, which was not available. This is equipped with a six-dimensional sensor called 6W-CDS that can measure the rotational moment around each axis in addition to the three-dimensional acceleration sensor for ABS, front and back, left and right, and up and down. This system allows the braking force to be controlled even when the tires are skidding.
The Ferrari Dynamic Enhancer (FDE) is responsible for torque vectoring, and in the SF90XX it has evolved to 2.0. By the way, SF90XX is the first Dynamic Manettino that allows FDE to work no matter which mode is selected.
The role of Electronic Side Slip Control (eSSC) 1.0 is to organically utilize these numerous systems and appropriately control the powertrain and chassis. In other words, eSSC is the brain of SF90XX.
Beauty as a result of prioritizing function: DESIGN
- The front S-duct has both the intake and outlet ports in a different color from the body, making its presence more obvious.
- It is thought that the same effect was achieved by decorating the end plates of the large rear wing with accent colors.
- The interior has been made lighter by simplifying the door lining. You will be surprised at how light the door moves when you open and close it.
As the “first XX model that can be driven on public roads,” the SF90XX naturally incorporates all the racing technology that Ferrari has cultivated over the years. Therefore, Centro Stile, led by Flavio Manzoni, worked closely with the technical development team and decided to change the interior and exterior of the SF90XX in a way that would emphasize rather than hide such racing technology.
For example, the S-duct, which increases downforce at the front, makes its presence more obvious by painting both the intake and outlet in a different color from the body. It is thought that the same effect was achieved by painting the end plates of the rear wing, which are installed independently, in accent colors.
Additionally, since it is equipped with an independent rear wing, visual balance was achieved by reducing the volume around the rear fender compared to the SF90, for example. Particularly impressive is the fact that the thickness of the rear fender has been shaved off.
Similarly, at the rear, the taillights have been changed from a rectangular four-lamp type to a stripe type that spans the entire width of the body, and the shape of the rear diffuser has been drastically revised, giving the impression that the entire tail end has become an air outlet. Give to the beholder.
In the interior, weight was reduced by simplifying the door lining. You will be surprised at how light the door moves when you open and close it. In addition, the upper part of the dashboard was covered with Alcantara, and the interior of the center tunnel, like the doors, was kept simple in an effort to reduce weight.
Although the design modifications have been extensive, it is remarkable that the SF90 has not lost any of its original beauty and quality. In this respect as well, it can be said that Centro Stile has done an admirable job.
