UK police forces are currently evaluating a version of the Jaguar XF Diesel S designed to be a high-performance pursuit vehicle.

The base model is the XF 3.0 Diesel S Luxury and adds on a roof-mounted light bar with 3600 blue flashing lights and integrated side alley lights, blue and white flashing LEDs inside the front grille, side mounted blue flashing LED lights, blue and red flashing LED lights integrated in the rear lamp clusters, and a Home Office-specification electronics ‘Police pack’ to power the full suite of lights, radio and other police equipment.

The XF Diesel S is powered by a 3.0 litre turbodiesel V6. 0 to 60mph can be hit in 5.9 seconds. There are two versions of this engine available and the one in the Diesel S is a twin turbocharged “parallel-sequential” version where a small turbo is used at low revs to quickly build up boost while at high revs a bigger one takes over, much like the engines in the BMW 335d and 123d.
