AERODYNAMICS
As well as facilitating packaging excellence, the XF’s new design language has another significant functional advantage: for the first time on any Jaguar, the entire body was developed using Computational Fluid Dynamics (CFD) before the car ever saw a wind tunnel. Every area from the outer skin to the lightweight, composite undertray to the cooling airflow (even the shape of the exterior mirrors) was optimised using this process. The higher, squarer tail is more efficient aerodynamically than a lower, rounded one, and the XF’s coupe-like roofline and subtle, raised bootlid lip improve airflow over the rear of the car. As a result, the XF has the best aerodynamic performance, in terms of drag, of any production Jaguar ever and is better than the race-bred, limited edition XJ220 supercar.
The XF’s drag coefficient is just 0.29 and the front-to-rear lift balance is precisely zero. This aerodynamic performance contributes to impressively low wind noise, aids fuel consumption and strong high-speed stability and, of course, is vital in ensuring ideal handling balance through optimising drag and lift forces.
