The outstanding aerodynamics and driving stability of the GS F are the product of a relentless focus on optimizing the aerodynamics. Careful attention was paid to honing details, including the brake cooling ducts, air outlets in the rear of the front fenders that vent air from the engine compartment, front spats and CFRP (Carbon Fiber Reinforced Plastic) rear spoiler. This attention to detail extends to the underbody. Optimizing the engine and floor under covers and the position of aero stabilizing fins creates a smooth airflow under the floor from the front through to the rear.
