Hot Pursuit!
The first ever Police-spec XF is currently being evaluated by Police forces across the UK. The Police specification Jaguar features the 275PS 3.0-litre Diesel S engine with its unique, parallel sequential turbocharger system. Delivering high torque throughout the entire rev range, improved throttle response and low CO2 emissions, the twin-turbochargers work sequentially to deliver unrivalled response and best-in-class torque that means the XF packs a huge punch at all engine speeds.
