Despite a monstrous rear wing and a low-riding front air dam, the drag coefficient of the GT2 has increased to 0.34 from the Turbo's 0.31. This increase results mainly from the bigger air intakes that channel more air to the brakes and to no fewer than three radiators and two intercoolers. The key aerodynamic improvement over lesser 911s is the larger center intake that guides air through the main radiator before sending it through a full-width duct to vents between the nose cone and hood. This substantially increases front-end downforce and, at the same time, reduces the amount of air that passes between the road and the floorpan by an impressive 60 percent. The ground-effects front end pays off at speeds of 80 mph and above, tying the nose down in a thoroughly convincing manner.
