NEW Mercedes-AMG GT 63 4MATIC+ Coupé | Aerodynamic Explained. The second-generation Mercedes‑AMG GT Coupé is the new top model offered by Mercedes‑AMG. It combines highly dynamic driving characteristics with increased suitability for everyday use.
Active aerodynamics for good balance and high efficiency
A key development focus of the new AMG GT Coupé was high aero efficiency, specifically: a perfectly balanced relationship between low air resistance and reduced lift. Here, the sporty coupé benefits from the extensive active aerodynamic elements at the front and rear. All flow-optimising elements are seamlessly integrated into the exterior design. The aerodynamics of the AMG GT Coupé meet the complex requirements of driving stability, air resistance, cooling and wind noise. The aero balance makes it possible to defuse critical driving situations, such as sudden evasive manoeuvres at high speed.
A technical highlight in the aero development is the two-part, active air control system AIRPANEL. The first part operates with vertical slats that are hidden behind the lower air intake in the front apron. The second part is located behind the upper air intake and has horizontal louvres. Normally all slats are closed. This position reduces air resistance and makes it possible to direct the air towards the underbody, further reducing the front lift. Only when certain temperatures have been reached on pre-defined components and the need for cooling air is particularly high do the fins open (the second system only from 180 km/h) and allow maximum cooling air to flow to the heat exchangers.
Another active component is the retractable rear spoiler that is seamlessly integrated into the trunk lid. It changes its position depending on the driving situation. The control software takes numerous parameters into account, including the driving speed, longitudinal and lateral acceleration, and the steering speed. Above 80 km/h, the spoiler assumes five different angular positions to either optimise driving stability or reduce air resistance.
The active aerodynamic element, which is hidden in the underbody in front of the engine, also contributes to the improved handling. This carbon profile, which weighs around two kilograms, is an exclusive AMG development and protected by patents. It reacts to the position of the AMG drive programmes and automatically lowers by around 40 millimetres at a speed of 80 km/h. This creates a Venturi effect, which sucks the car onto the road and reduces lift on the front axle. The driver feels this positively in the steering as the AMG GT Coupé can be steered more precisely in bends with even more directional stability.
An aerodynamic package is also available as an option. This includes additional flics on the outer air intakes and on the wheel arches. At the rear, the airflow is optimised by side flics on the rear apron, a larger diffuser attachment and a fixed rear wing. All in all, the aerodynamics package reduces lift on the front axle and increases downforce on the rear axle.
