While the design of the fourth generation of the XJ started in 2005, under Ford management, the model was launched in 2009 under the new, Tata Motors management. It was renewed in 2012. The Jaguar XJ didn't face too many generations. The first XJ was launched in 1968 and it was refreshed several times. It was the same situation with the following generations so, the British company decided to do the same with the fourth model. But it had to be refreshed and had to receive new engines to comply with the Euro 6 pollution norms. From the outside, the car didn't receive obvious changes. The standard version received a set of 19” light-alloy wheels. The heated windshield was available from the 2009 model, but it became standard for the 2012 facelift. A full-length panoramic glass roof was installed to offer an additional sense of spaciousness. Like the 2009 model, the 2012 facelift was available in standard or long-wheelbase versions. Inside, there were more changes. A full digital 12.3” instrument cluster was included and more comfort features were included in the long-wheelbase package. The 8” dual-view infotainment screen was fitted as standard for all the range. Under the skin, the 2012 XJ received more aluminum components, making the car lighter than before. The standard transmission was an 8-speed automatic, replacing the older gearbox that brought a lot of complaints in terms of reliability.
