Ferrari presents its flagship SF90 in extreme XX Stradale and XX Spider versions.
The XX program has always been dedicated to the most demanding customers, offering Ferrari’s models in extreme versions exclusively for the racetrack. The goal of the program was to bring production vehicles as close as possible to racing cars, but as a result, the XX versions were not homologated for road use. This is now changing, as the Italians are introducing their historically first XX models that can be driven on public roads as well.
This is the current flagship model, which comes in an enhanced version as the SF90 XX Stradale and SF90 XX Spider. The XX rendition is available for both body styles, including the model capable of folding/unfolding the roof in 14 seconds. Their shared feature is the 4-liter Twin-Turbo V8 engine, whose output has increased from 574 kW/780 horsepower to 586 kW/797 horsepower, while the electric motors have also become more powerful (from 162 kW to 171 kW).
The resulting power of the entire system is now up to 758 kW/1,030 horsepower. The present battery with a capacity of 7.9 kWh can provide an electric range of approximately 25 kilometers under ideal conditions, but in this case, the electric system primarily serves a different purpose.
The electric motors are designed to assist the conventional power unit, resulting in improved flexibility and faster acceleration. Regardless of the body style, these novelties can accelerate from 0 to 100 km/h in just 2.3 seconds, reach 200 km/h in 6.7 seconds, and achieve a maximum speed of 320 km/h. Power is transmitted to the wheels through the 8-speed F1 DCT transmission. In addition to the increased performance of the XX versions, they also feature enhanced brakes (with rear discs up to 390 mm in diameter) and new electronic systems that monitor speed and optimize braking efficiency.
Significant improvements are also evident in the field of aerodynamics, ensuring better airflow around the body, enhanced cooling of the technology, and improved heat dissipation from the brakes. After many decades, Ferrari has also incorporated a substantial, fixed rear wing, which, thanks to aerodynamic enhancements, generates up to 530 kilograms of downforce at a speed of 250 km/h. The automaker plans to produce 799 units of the Stradale version and 599 units of the Spider variant.
