The Mercedes-AMG GT XX concept represents a bold step into the future of electric vehicle (EV) technology, showcasing cutting-edge advancements in performance and charging capabilities. Among its many innovative features, the active aero system stands out, particularly the active aero wheels. These wheels are designed to dynamically adjust, opening and closing to either maximize brake cooling or reduce the car’s drag coefficient, depending on the driving conditions. This adaptability is crucial for a vehicle designed to reach speeds exceeding 223 mph (360 km/h), where aerodynamic efficiency becomes paramount.
At such high speeds, air resistance becomes a significant hurdle. The Mercedes-AMG GT XX has undergone extensive wind tunnel testing to achieve an exceptionally low drag coefficient of just 0.198. To put this into perspective, it’s even more streamlined than the Volkswagen XL1, which holds the title of the most aerodynamic production car ever made. This focus on aerodynamics is not merely for show; it directly impacts the car’s performance and energy efficiency. For instance, at 186 mph (300 km/h), approximately 83% of the car’s power is dedicated to overcoming air resistance.
To effectively manage airflow, the AMG GT XX employs powered louvers at the front of the vehicle. These louvers offer a wide range of motion, allowing for precise control over airflow. The vehicle’s control system aims to keep these louvers closed as much as possible to maintain optimal aerodynamic efficiency. Additionally, the car features a completely flat underbody and a rear diffuser, which work together to create a Venturi effect. This effect helps to keep the car firmly planted on the road at high speeds. Even the design of the side skirts plays a role in carefully directing airflow around the vehicle.
While the Mercedes-AMG GT XX boasts numerous aerodynamic enhancements, including advanced active aero elements, the most groundbreaking feature is undoubtedly its active aero wheels. Unlike other active aero systems found in production cars, the GT XX incorporates flaps on the wheels themselves. These flaps open and close to either facilitate brake cooling or reduce aerodynamic drag, offering a unique approach to optimizing performance.
What sets these active aero wheels apart is their innovative use of technology. Each wheel is equipped with a central hub that draws power from the wheel’s rotation, eliminating the need for a direct cable connection to the car’s central systems. Instead, the wheels communicate wirelessly via Bluetooth, a novel application of wireless connectivity in automotive engineering. This Bluetooth connection allows the wheels to receive instructions on when to open or close, based on real-time driving conditions and performance needs. The implementation of Bluetooth-enabled wheels is a significant departure from traditional automotive designs and highlights Mercedes-AMG’s commitment to pushing the boundaries of innovation.
| Feature | Description | Benefit |
|---|---|---|
| Active Aero Wheels | Flaps open/close based on driving conditions | Optimized brake cooling and reduced drag |
| Bluetooth Connectivity | Wireless communication with car’s system | Eliminates need for cables, simplifies design |
| Self-Powered Hub | Generates power from wheel rotation | Autonomous operation, no external power source |
When questioned about the possibility of these innovative wheels making their way into production vehicles, Mercedes-AMG CEO Michael Schiebe hinted that the chances were “not low.” This statement has sparked considerable excitement among automotive enthusiasts and industry experts alike. Schiebe further elaborated that the concept originated from an engineer’s personal project, developed independently and later presented to management, who embraced the idea due to its novelty and potential.
However, the path to production is not without its challenges. One notable concern is the vulnerability of the open Bluetooth wheels to curb damage during parking maneuvers. Protecting these wheels from curb rash will be a critical consideration in the design and engineering process. Ultimately, the decision to incorporate active aero wheels into production vehicles will depend on whether the benefits they offer in terms of cooling and aerodynamics justify the added complexity and cost. Rigorous testing and analysis will be necessary to determine the real-world impact of these wheels on vehicle performance and efficiency.
The development of Bluetooth active aero wheels represents a significant advancement in automotive technology. Their potential introduction into production vehicles could mark a new era of aerodynamic innovation, enhancing both performance and efficiency. As Mercedes-AMG continues to explore the possibilities of EV technology, the future of these wheels remains a topic of great interest and anticipation.
