2014 Jaguar XF Gets New Diesel Engine

Font size: Decrease font Enlarge font

The Jaguar XF has been updated for the 2014 model year, with changes including Jaguar's new four-cylinder, 2.2-liter diesel 161 hp ECO2 engine and an upgraded sat-nav system.

The 2.2-liter four-cylinder ECO2 engine is offered in combination with Jaguar's Intelligent Stop-Start system and an eight-speed gearbox, enabling the 2014 Jaguar XF to deliver the performance and driver appeal expected of a Jaguar along with reduced emissions and greatly improved fuel consumption.

Jaguar's new four-cylinder, 2.2-liter diesel 161 hp (120 kW) ECO2 engine, which is paired with 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 2014 Jaguar XF is capable of achieving 57.7mpg (4.9 l/100km or 48 mpg US) with a CO2 figure of just 129g/km.

The low emissions produced by the ECO2 engine are helped further by Jaguar's Stop-Start system, which uses a Twin Solenoid Starter (TSS) to shut down the engine when the car comes to a halt and restarting it in less time than it takes for the driver's foot to move from the brake to the accelerator. The system also offers 'change of mind' functionality, enabling the engine to quickly restart even during its rundown phase to allow the driver to, for example, exploit a gap in traffic at a junction.

An illuminated 'ECO' symbol appears on the Instrument Panel when the engine has been stopped by the system. Stop-Start can be turned off manually, but it will automatically be turned on again for the vehicle's next journey with every ignition cycle. The system operates in all modes apart from Reverse.

The 2014 Jaguar 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.

Prices and an on-sale date for the 2014 Jaguar XF are yet to be confirmed.
