Visually and technically, the new 911 GT3 is a highly integrated feat of engineering. As with every Porsche, the exterior form is defined by its technical function. Every line, every surface, every curve of the bodywork has been carefully fashioned to enhance the performance of the automobile.
The aerodynamic elements of the front of the car are a major source of downforce that pushes the front of the 911 GT3 to the road. A key element in this approach is the narrow vent located ahead of the front deck lid. Incoming air is channeled through the radiator and expelled over the top of the car. This simple solution results in a significant degree of positive front-end downforce. The new front apron features a range of aerodynamic refinements, which help to cool the brakes and direct air to the central radiator. The third radiator unit is a necessary addition to compensate for the higher thermal loads on the engine.
The most prominent feature at the rear of the car is the fixed biplane wing structure, which creates greater stability at high speed. The upper wing element has an adjustable angle of incidence, which allows finetuning of the aerodynamic setup. An interesting detail on the lower wing surface is the smaller rubber spoiler or “Gurney flap”: This device creates added downforce with a negligible increase in drag. As the car’s speed increases, a pair of “air collector” openings on the engine lid help to force air into the intake manifold as well as the engine compartment. Warm air around the engine is expelled from the car through a system of vents on the rear apron.
The combined effect of all these aerodynamic refinements is another remarkable achievement: Rather than merely limiting aerodynamic lift, they combine to generate positive downforce on the front and rear axles. The resulting benefits include increased levels of grip, greater directional stability, enhanced active safety and better all-around handling.
