Jaguar XK

The Jaguar XF is a mid-size luxury car / sports saloon made by Jaguar Cars, as a replacement of the Jaguar S-Type. The Jaguar C-XF (for Concept-XF) was a concept car that was designed to showcase the preliminary styling cues of the upcoming Jaguar XF. The C-XF project was led by Jaguar Director of Design Ian Callum and Head of Advanced Design Julian Thomson.

TIt included a 4.2-litre supercharged V8 engine, a 6-speed automatic transmission with Jaguar Sequential Shift, single slim-wedged headlamps which have evolved from the twin-lamp motif seen on past Jaguars, performance-themed interior, JaguarDrive Selector, Dual View screen, and a Bowers & Wilkins audio system. The vehicle was unveiled in the 2007 North American International Auto Show. The styling of the finalised production XF varies from that of the C-XF, most notably around the front lights and nose, which incorporates an oval mesh grille harking back to the original XJ of 1968 and is destined to be a feature of future Jaguars. The boot lid has retained the S-Type's chromed blade to its edge, but now sports a "leaper" as well. Boot space and practicality is much improved over its predecessor, with the option of carrying a puncture repair kit instead of a spare wheel to create further space although this feature is not available in some markets. The car 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 coupé-like roofline and 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 0.29, and the front-to-rear lift balance is precisely zero. This aerodynamic performance minimises wind noise, reduces fuel consumption, and aids strong high-speed stability and handling.
