The Ferrari SF90 Stradale, taking its name from the 90th anniversary of Scuderia Ferrari and “Stradale” meaning “road” in Italian, is a landmark vehicle for the Prancing Horse. It marks their first series-production plug-in hybrid electric vehicle (PHEV), showcasing a potent blend of traditional Ferrari V8 power with cutting-edge electric technology. This detailed exploration delves into the specifications, performance metrics, design elements, technological innovations, pricing details, and the overall significance of the SF90 Stradale in the automotive landscape.
I. Powertrain and Performance: A Symphony of Power:
The SF90 Stradale’s powertrain is a complex yet harmonious combination of a high-revving V8 engine and three electric motors, resulting in exceptional performance and efficiency.
- Internal Combustion Engine (ICE): The heart of the SF90 is a 4.0-liter twin-turbocharged V8 engine, internally codenamed F154CD. This engine, a development of the V8s found in other Ferrari models like the F8 Tributo, has been significantly reworked for this hybrid application. It generates 769 hp (573 kW) at 7,500 rpm and 590 lb-ft (800 Nm) of torque at 6,000 rpm.
- Electric Motors (Three Motors, All-Wheel Drive): The SF90 distinguishes itself with not one, but three electric motors. One motor is positioned between the engine and the 8-speed dual-clutch transmission, acting as an MGU-K (Motor Generator Unit, Kinetic). This motor assists the engine in acceleration and recovers energy during braking. The other two electric motors are located on the front axle, giving the SF90 all-wheel-drive capability, a first for a series-production Ferrari sports car.
- HY-KERS System (Hybrid Kinetic Energy Recovery System): The HY-KERS system is crucial for the SF90’s hybrid functionality. It recovers kinetic energy during braking and deceleration, converting it into electrical energy stored in a 7.9 kWh lithium-ion battery pack. This stored energy powers the electric motors, providing supplementary power, enhancing acceleration, and enabling short periods of electric-only driving.
- Combined Power Output: The combined output of the V8 engine and the electric motors is a staggering 986 hp (735 kW), making the SF90 Stradale the most powerful series-production Ferrari to date.
- Transmission: An 8-speed dual-clutch transmission, a refined version of the one found in the 488 Pista, manages the power delivery to all four wheels. It provides incredibly fast and seamless shifts, contributing to the car’s rapid acceleration.
- Performance Figures: The SF90 Stradale boasts impressive performance statistics:
- 0-60 mph (0-97 km/h): Approximately 2.5 seconds
- 0-124 mph (0-200 km/h): 6.7 seconds
- Top Speed: 211 mph (340 km/h)
- Electric-Only Range: Around 16 miles (25 km)
II. Chassis, Suspension, and Brakes: Precision Engineering:
The SF90 Stradale’s chassis, suspension, and braking systems are meticulously engineered to provide exceptional handling, stability, and control.

- Chassis: The car utilizes a lightweight multi-material chassis constructed from carbon fiber and aluminum. This combination provides exceptional torsional rigidity and strength while minimizing weight, contributing to the car’s agility and responsiveness.
- Suspension: The SF90 employs a double-wishbone suspension setup at both the front and rear axles. This sophisticated suspension design ensures precise wheel control, optimal tire contact with the road, and exceptional handling characteristics.
- Brakes: Brembo carbon-ceramic brakes provide immense stopping power and excellent resistance to brake fade, crucial for maintaining consistent braking performance during demanding driving situations.
III. Aerodynamics: Mastering Airflow:
Aerodynamics play a pivotal role in the SF90 Stradale’s performance, with both passive and active aerodynamic elements working in concert.
- Active Rear Spoiler (Shut-off Gurney): The most prominent aerodynamic feature is the active rear spoiler, known as the “shut-off Gurney.” This innovative system dynamically adjusts the level of downforce based on the car’s speed and driving mode. At high speeds, it lowers to minimize drag and maximize straight-line speed. During cornering and braking, it raises to generate increased downforce, improving stability and grip.
- Vortex Generators: Strategically placed vortex generators on the underbody and rear diffuser help manage airflow, creating vortices that increase downforce and improve aerodynamic efficiency.
IV. Design and Styling: Form Follows Function:
The SF90 Stradale’s design is a striking combination of aerodynamic efficiency and aesthetic beauty, with every line and curve serving a purpose.
- Exterior Design: The exterior design is characterized by its sleek silhouette, aggressive lines, and prominent aerodynamic elements. The low profile, wide stance, and distinctive front and rear fascias give the SF90 an unmistakable presence.
- Interior Design: The interior is focused on the driver, featuring a minimalist design with high-quality materials and intuitive controls. The digital instrument cluster and head-up display provide essential information to the driver without distracting from the driving experience.
V. Technology and Innovations: A Showcase of Innovation:
The SF90 Stradale is a technological tour de force, incorporating several advanced systems:
- eManettino: This electronic control system allows the driver to select various driving modes, which adjust the hybrid system’s behavior, traction control, stability control, and other vehicle dynamics. The modes include eDrive (electric-only), Hybrid (optimizes efficiency), Performance (prioritizes performance), and Qualify (unleashes maximum power).
- Brake-by-Wire System: This advanced braking system integrates the traditional braking system with the hybrid system’s regenerative braking function, optimizing braking performance and maximizing energy recovery.
- RAC e-Diff (Electronic Differential): This electronic differential manages torque distribution between the rear wheels, enhancing traction, improving handling, and allowing for precise control during cornering.
VI. Pricing and Options: Exclusivity and Personalization:
- Base Price: The starting price for the SF90 Stradale is typically around $500,000 USD, but this can vary depending on market conditions and specific configurations.
- Options and Customization: Ferrari offers extensive options and customization possibilities through its Tailor Made program, allowing buyers to personalize their cars with unique colors, materials, and finishes. These customizations can significantly increase the final price.
- Secondary Market Values: Due to its limited production numbers and high demand, the SF90 Stradale often commands prices significantly above its original MSRP on the secondary market.
VII. SF90 Spider: Open-Air Thrills:

The SF90 Spider is the open-top variant of the SF90 Stradale, featuring a retractable hardtop that can be deployed or retracted in just 14 seconds, even while the car is moving at low speeds. The Spider offers a similar driving experience to the Stradale, with only minor differences in performance due to the added weight of the roof mechanism.
VIII. Competition: Standing Among Giants:
The SF90 Stradale competes in the highly competitive hybrid supercar segment, facing rivals such as the Lamborghini Revuelto, and previously the McLaren P1 and Porsche 918 Spyder (though these are now out of production).
IX. Legacy and Significance: A New Era for Ferrari:
The SF90 Stradale represents a pivotal moment in Ferrari’s history, marking its first foray into series-production plug-in hybrid technology. It demonstrates the company’s commitment to innovation and its ability to seamlessly blend high performance with advanced electrification.
