The 2014 Model Year Jaguar XF , featuring the new four-cylinder, 2.2-litre diesel 163PS ECO2 engine, is capable of achieving 57.7mpg with CO2 emissions of just 129g/km.
The MY14 XF with the ECO2 engine is offered with an Intelligent Stop-Start system that uses a Twin Solenoid Starter (TSS) to shut down the engine when the car comes to a halt, helping to reduce emissions and improve fuel consumption.
Jaguar’s new four-cylinder, 2.2-litre diesel 163PS ECO2 engine, which works in combination with an eight-speed automatic transmission, has new larger Exhaust Gas Recirculation valves and a revised cooling assembly which combine to reduce emissions figures by a further 6g/km of CO2 over the 2013 Jaguar XF.
The MY14 XF has a secondary battery fitted specifically for engine re-starting, meaning that all the normal car systems – such as the entertainment system, the ventilation and lights – continue to receive power from the standard car battery and are unaffected by the re-start. In addition, a complex control system ensures that the Stop/Start operation only occurs when the car does not require the engine for other functions.
