No mild breath of air. No gentle breeze. The signs show a storm is brewing. A glance at the new 718 Cayman GT4 is enough to see: air resistance is not an issue. The aerodynamics concept of the new 718 Cayman GT4 has been honed once more. Starting with the front fascia. Its clearly defined form with the typical Porsche sweepback gives the headwind an explicit direction and a clear purpose: to produce optimum tire contact pressure. The highly distinctive front spoiler lip with an additional spoiler in front of the wheel arches provides aerodynamic downforce on the front axle. The central air intake in the front fascia also optimizes the aerodynamics and channels the air stream up through the air outlet in front of the front fender. Even the underside of the front spoiler lip has been aerodynamically optimized. Here, a special profile – similar to the surface of a golf ball – ensures as little drag as possible. Air curtains in the front fascia minimize the air turbulence created on the wheels and therefore minimize the drag by releasing the inflowing air precisely in front of the wheels from the wheel arches.
The new air intake grilles are equipped with a honey combstyle surface finish, meaning they offer the headwind less drag, however, they still reliably protect the radiator from small debris – and eat flies for breakfast. A further example of the performance-oriented design is the side air intakes behind the doors: the sideblades, embossed with the ‘GT4’ logo, create additional dynamic pressure. The result: a better supply of air and more efficient engine cooling. The vehicle center of gravity: low. The distance to the road: minimal. The new 718 Cayman GT4 is in close contact with everything that is important to it. Platinum-colored 20-inch alloy wheels, which almost completely fill the wheel arches, ensure optimum contact. The wide track, in conjunction with the ultra-high performance (UHP) summer tires, improves both the traction and the cornering performance.
The rear is dominated by the fixed, now single-piece wing with integrated sideblades and supports in aluminum. Its racetrack origins are unmistakable, it provides downforce on the rear axle and correspondingly high traction – not just when cornering. Simultaneously, it ensures clarity and tells all optimists who want to overtake the new 718 Cayman GT4: forget it. Sporty end towards the tarmac: the new rear fascia. The two black tailpipes of the sport exhaust system are positioned clearly further apart, creating space for the new diffuser. No visual frills, just super sports car technology which produces very fast air flow at the rear underbody and therefore even stronger negative pressure or 40% more downforce on the rear axle than the previous model. The rest is silence. At least among the rivals of the new 718 Cayman GT4.
