The new 2.2 liter Jaguar XF image

Jaguar unveiled one of the most economical Jag ever made – the 2.2-litre four-cylinder Jaguar XF.

The new Jag equipped with this new 2.2-liter four-cylinder engine has 190 PS and 332 lbs ft of torque, allowing the car to accelerate from rest to 62mph in 8.5-seconds before reaching a top speed of 140mph.

The XF 2.2 emits 149 g/km of CO2. Further improving efficiency, the new 2.2-litre engine is linked to a new eight-speed ZF automatic gearbox and an innovative Stop-Start system – marking the first time such a device has been fitted to a Jaguar.

Alongside the new powertrain, the Jaguar XF has a modified interior and exterior style. A completely new front end with new slimmer headlight units complete with LED lighting strips and a larger grille. Rear tail lamp units now feature LED technology.

Set to be launched in September, the new XF 2.2 forms part of the new 2012 model range.
