Mercedes-AMG GT XX: Bluetooth-Enabled Active Aero Wheels

The Mercedes-AMG GT XX Concept: A New Era of Aerodynamics

The Mercedes-AMG GT XX concept car represents a significant leap forward in EV tech, particularly in performance and charging capabilities. Beyond its impressive EV credentials, this concept showcases innovative features designed to optimize aerodynamic efficiency. One of the most notable is its active aero wheels, which adapt to driving conditions by opening and closing to either enhance brake cooling or reduce drag. This level of adaptability is crucial for a vehicle designed to reach speeds exceeding 223 mph (360 km/h), where air resistance becomes a dominant factor.

The development of the GT XX involved extensive wind tunnel testing, resulting in an exceptionally low drag coefficient of just 0.198. To put this into perspective, that’s even more streamlined than the Volkswagen XL1, which previously held the title of the most aerodynamic production car ever made. This focus on minimizing air resistance is vital; at 186 mph (300 km/h), approximately 83% of the car’s power is dedicated to overcoming aerodynamic drag. The GT XX manages airflow using powered louvers at the front, offering precise control beyond simple open and closed positions. These louvers, combined with a flat underbody, rear diffuser, and carefully designed side skirts, work together to maximize aerodynamic efficiency and ensure the car remains stable at high speeds.

Active Aero Wheels: Revolutionizing Airflow Management

While the Mercedes-AMG GT XX concept incorporates various advanced aerodynamic features, its active aero wheels stand out as a particularly innovative element. Many production cars already feature sophisticated active aero systems, but none have integrated them into the wheels themselves. The GT XX’s wheels are equipped with flaps that open and close to either cool the brakes or reduce aerodynamic drag, offering a dual benefit that enhances both performance and efficiency.

These active aero wheels are connected to a central hub that derives power from the wheel’s rotation. Remarkably, they operate without any wired connection to the car, instead relying on a Bluetooth connection for communication. This wireless approach represents a novel application of Bluetooth technology in automotive engineering. The system allows for real-time adjustments based on driving conditions, optimizing airflow around the wheels to improve overall performance. The integration of Bluetooth-enabled wheels is an unexpected yet fascinating development in automotive technology, pushing the boundaries of what’s possible in vehicle design.

Hurdles and Future Prospects of Bluetooth Wheels

The potential for these active aero wheels to make it into production is “not low,” according to Mercedes-AMG CEO Michael Schiebe. The idea originated from an engineer’s personal project, highlighting the importance of individual initiative within the company. The unique and unprecedented nature of the concept has garnered widespread enthusiasm within Mercedes-AMG. However, practical challenges remain, particularly concerning the vulnerability of the open wheels to curb damage during parking maneuvers.

While addressing curb rash is a manageable concern, the ultimate decision to implement these active wheels in production models hinges on their actual performance benefits. Mercedes-AMG must determine whether the active aero wheels offer a significant advantage in terms of brake cooling and aerodynamic efficiency. Furthermore, the added complexity and cost of these wheels must be justified by tangible improvements in vehicle performance and efficiency. The future of Bluetooth-enabled active aero wheels depends on a delicate balance between innovation, practicality, and cost-effectiveness.
