Couldn't have a better business card: Ferrari SF90 Stradale, the most powerful road Ferrari ever. It even surpasses the LaFerrari… and not a V12 in sight — we'll be right there…
Project 173 — code-named the SF90 Stradale — is a milestone in Ferrari history, a concentrate of technology that reveals much of what the Italian brand's future will be — electrification will certainly be a big part of that future. This is the first plug-in hybrid to carry the rampant horse symbol.
Why SF90? A reference to the Scuderia Ferrari's 90th anniversary, with the Stradale indicating that it is a road model — SF90 is also the name of Ferrari's Formula 1 car, so the addition of Stradale… sets the two apart.
Discover the numbers that define the Ferrari SF90 Stradale, and what lies behind them:
1000
The key number for this model. It is the first Ferrari on the road to achieve a four-digit value, surpassing the 963 hp of the LaFerrari — which also combined a combustion engine with an electrical component — but the way in which it hits them couldn't be more different.

Unlike the LaFerrari, there's no raucous V12 behind its back — the SF90 Stradale uses an evolution of the award-winning V8 twin turbo (F154) of the 488 GTB, 488 Pista and F8 Tribute. The capacity has grown slightly from 3.9 to 4.0 l, with many of its components being redesigned, such as the combustion chamber, and the intake and exhaust systems.
The result are 780 hp at 7500 rpm and 800 Nm at 6000 rpm — 195 hp/l —, with the 220 hp missing to reach 1000 hp to be provided by three electric motors — one positioned at the rear between the engine and the gearbox (MGUK — kinetic motor generator unit, as in the F1) , and the other two positioned on the front axle. That's right, the SF90 has four-wheel drive.

It doesn't just refer to the number of cylinders, it's also the number of speeds of the new dual-clutch gearbox. More compact, a consequence of the new clutch and dry sump, which not only allows a 20% smaller diameter compared to the seven-box we already know, but also allows it to be positioned 15 mm closer to the ground, contributing to a more center of gravity. low.
It's also 7 kg lighter, despite having one more speed and supporting 900 Nm of torque (+20% than current). Those 7 kg less increase to 10 kg, since the SF90 Stradale does not require the reverse gear ratio — this functionality is replaced by electric motors.
According to Ferrari, it is also more efficient, responsible for reducing consumption by up to 8% (WLTP) on the road and a 1% increase in efficiency on the circuit; and faster — just 200ms to change ratio versus 300ms for the 488 Lane box.

1000 hp, four-wheel drive, (some) instantaneous torque thanks to electric motors, and a super-fast double-clutch gearbox could only guarantee high-caliber performance. The 100 km/h is achieved in 2.5s, the lowest value ever recorded on a road Ferrari and the 200 km/h is reached in a mere 6.7s . The maximum speed is 340 km/h.270
As you can imagine, marrying the internal combustion engine with three electric motors and a battery, the SF90 Stradale would never be too light. The total weight amounts to 1570 kg (dry, ie without fluids and conductor), of which 270 kg refer only to the hybrid system.
However, many measures were taken by Ferrari to control the weight. The SF90 Stradale debuts a new multi-material platform, where we find, for example, a carbon fiber bulkhead between the cabin and the engine, and we see the introduction of new aluminum alloys — Ferrari announces 20% more flexural strength and 40% torsion over previous platforms.
If we opt for the Assetto Fiorano pack, we can take another 30 kg off the weight, by including carbon fiber car back and door panels, and titanium springs and exhaust line — it also adds other “treats” like competition-derived Multimatic shock absorbers .

The Ferrari SF90 Stradale is the brand's first plug-in hybrid (PHEV), and this feature also allows for browsing up to 25 km only using batteries and two front electric motors. In this mode (eDrive), we can reach a maximum speed of 135 km/h and it is the only way to have access to reverse gear.390
Ferrari announces 390 kg of downforce for the SF90 Stradale at 250 km/h — unsurprisingly, aerodynamics was an extremely important focus in designing Maranello's new high-performance machine.
We have optimized vortex generators at the front — raising the front chassis section by 15 mm relative to others — but it's the rear that gets all the attention. There we find a suspended wing divided into two sections, a fixed one (where the third stop light is located) and a mobile one, which Ferrari refers to as “shut-off Gurney”. How the two wing sections interact depends on context.
When driving in the city or when we want to reach maximum speed, the two sections are aligned, allowing air to circulate above and below the “shut-off Gurney”.
When maximum downforce is required, electric actuators lower the wing's movable section, or “shut-off Gurney”, preventing air from passing under the wing, leaving the fixed section visible, and creating a new rear geometry, more friendly to aerodynamic load.

Inside the Ferrari SF90 Stradale we find an evolution of the Manettino, called… eManettino. This is where we can select the various driving modes: eDrive, Hybrid, Performance and Qualify.If the first is what gives access to 100% electric mobility, the hybrid is the default mode where management between combustion engine and electric motors is carried out automatically. in mode performance , the combustion engine remains always on, with the priority being on battery charging, rather than efficiency in Hybrid mode. Finally, the mode Qualify is what unlocks all the performance potential of the SF90 Stradale, especially regarding the 220 hp provided by electric motors — only performance matters in this mode.

In order to involve the “pilot” as much as possible with the controls of the SF90 Stradale, Ferrari took its inspiration from aeronautics, and designed its first 100% digital instrument panel — a high definition 16″ curved screen, an absolute first in a production car.
And more?
It remains to mention the complexity of integrating all the driving elements in the calibration of traction and stability controls. The result of this laborious task led Ferrari to create a new iteration of its SSC, now called eSSC (Electronic Side Slip Control), which effectively distributes the power generated by the combustion engine or electric motor to the wheel that needs it.
It also debuts for a new by-wire braking system and the introduction of a torque vectoring system for the front axle.
Unlike other Ferrari super and hypersports, the SF90 Stradale will not have limited production, this is a series production vehicle — of the 2000 potential customers invited by Ferrari to present the new model, almost all have already ordered one, with the first deliveries planned for the first quarter of 2020.
The price will be somewhere between an 812 Superfast and a LaFerrari. It's the second new model introduced by Ferrari this year — the first was the successor to the 488 GTB, the F8 Tribute — and this year we'll still see the introduction of three more new models. A full year for the “little” Ferrari.
