The Art of Air: Exploring the Best Supercars with Active Aerodynamics
For decades, the pursuit of speed has been the driving force behind automotive innovation. While raw horsepower remains a critical factor, engineers have increasingly turned to the subtle yet powerful manipulation of airflow to unlock new levels of performance. This is where aerodynamics comes into play, and in the realm of supercars, it’s no longer just about static wings and splitters. The latest generation of high-performance machines are employing sophisticated active aerodynamic systems to optimize grip, stability, and overall speed, adapting to changing conditions in real-time.
Active aerodynamics refers to systems that dynamically adjust a vehicle’s aerodynamic profile to suit different driving situations. This can involve moving wings, flaps, diffusers, and other elements to increase downforce for cornering, reduce drag for straight-line speed, or even enhance braking performance. Unlike passive aerodynamic elements, which are fixed in place, active systems use sensors, computers, and actuators to constantly refine the car’s aerodynamic behavior, resulting in a significant performance advantage.
This article will explore some of the best supercars currently on the market that showcase the brilliance of active aerodynamics, delving into the specific technologies they employ and the performance benefits they deliver.
1. McLaren 720S and its Successors:
McLaren has been a pioneer in the application of active aerodynamics to road cars. The 720S, a benchmark supercar, features the ingenious Proactive Chassis Control II system, which integrates with the active rear wing. The rear wing not only adjusts its angle based on speed and braking but also acts as an airbrake, deploying rapidly to increase stopping power. Furthermore, the system uses sensors to monitor steering angle, throttle position, and other parameters to optimize downforce and balance, ensuring exceptional stability and control.
McLaren’s dedication to active aero is evident in its subsequent models as well. The Senna, a track-focused hypercar, takes active aerodynamics to an extreme. It features a massive active rear wing, active aero blades at the front, and underbody vortex generators that work in concert to generate immense downforce. The Senna’s active aero system is constantly adjusting, creating a dynamic aerodynamic profile that allows it to corner at incredible speeds. Even the longtail versions of the 720S and the newer 750S benefit from refined active rear wings, optimized for both downforce and reduced drag in high-speed scenarios.
Key Active Aero Features on McLaren Supercars:
- Adjustable Rear Wing: Varies angle based on speed, braking, and driving mode.
- Airbrake Function: Deploys rapidly under hard braking for increased stopping power.
- Active Aero Blades (Senna): Front blades adjust to optimize airflow and downforce.
- Proactive Chassis Control: Integrates with the active aero system for optimal balance and stability.
2. Ferrari SF90 Stradale and Assetto Fiorano Variants:
Ferrari has long been known for its aerodynamic prowess, and the SF90 Stradale, their first plug-in hybrid supercar, is no exception. The SF90 incorporates a complex active aero system that includes a shut-off Gurney, a suspended element located at the rear of the car. This system dynamically adjusts the rear downforce based on driving conditions.
In low-drag configurations, the shut-off Gurney lowers to minimize drag and maximize straight-line speed. In high-downforce configurations, it raises to increase downforce for improved cornering grip. The system is controlled by a sophisticated algorithm that takes into account speed, acceleration, steering angle, and other parameters. The Assetto Fiorano package adds further aero enhancements, optimizing the car for track use.
Key Active Aero Features on the Ferrari SF90 Stradale:
- Shut-off Gurney: A suspended element at the rear that adjusts downforce.
- Low-Drag Configuration: Gurney lowers to minimize drag.
- High-Downforce Configuration: Gurney raises to increase downforce.
- Sophisticated Control Algorithm: Optimizes aero performance based on driving conditions.
3. Lamborghini Huracan Performante and Successors:
Lamborghini’s entry into the active aero arena came with the Huracan Performante, featuring Aerodinamica Lamborghini Attiva (ALA). ALA is a lightweight system that uses electronically controlled flaps to modify airflow over the car. At the front, ALA opens flaps to reduce pressure on the front spoiler, directing air underneath the car to reduce drag and increase acceleration. At the rear, ALA can stall the rear wing to reduce drag or close the flaps to generate maximum downforce.
A unique feature of ALA is its ability to independently control the left and right sides of the rear wing. This allows for aerodynamic torque vectoring, which can improve cornering performance by increasing downforce on the inside wheel. The system is quick and responsive, adjusting in less than 500 milliseconds. Later models like the Huracan STO built on this technology, further refining the ALA system for track-focused performance.
Key Active Aero Features on Lamborghini Huracan Performante:
- Aerodinamica Lamborghini Attiva (ALA): Electronically controlled flaps that modify airflow.
- Front Flaps: Reduce pressure on the front spoiler to reduce drag.
- Rear Flaps: Stall the rear wing to reduce drag or close to generate downforce.
- Aerodynamic Torque Vectoring: Independently controls left and right sides of the rear wing.
4. Porsche 911 GT3 (992 Generation):
Porsche’s 911 GT3 (992 generation) is a testament to the effectiveness of active aerodynamics. While the 911 has always been known for its aerodynamic efficiency, the latest GT3 takes it to another level with its swan-neck rear wing and active front diffuser.
The swan-neck wing design allows for cleaner airflow underneath the wing, increasing its efficiency. The active front diffuser features adjustable elements that can be lowered to increase downforce at the front axle. The system is integrated with the car’s driving modes, automatically adjusting to optimize performance for different driving situations. These changes contribute to a significant increase in downforce compared to the previous generation, improving cornering grip and stability.
Key Active Aero Features on the Porsche 911 GT3 (992):
- Swan-Neck Rear Wing: Allows for cleaner airflow under the wing.
- Active Front Diffuser: Adjustable elements that increase downforce.
- Integration with Driving Modes: Optimizes aero performance for different situations.

Koenigsegg is known for pushing the boundaries of automotive engineering, and the Jesko is a prime example. It features a triplex damper system and advanced active aerodynamics to deliver incredible performance. The Jesko’s active rear wing is a marvel of engineering, capable of generating over 1000 kg of downforce.
The wing is controlled by a sophisticated algorithm that takes into account speed, acceleration, steering angle, and other parameters. It can adjust its angle to optimize downforce or reduce drag, depending on the driving situation. The Jesko also features active flaps under the front splitter, which further enhance its aerodynamic performance. The result is a car that is incredibly stable and planted, even at extreme speeds.
