JAGUAR’S diesel range continues to grow with the addition of a 2.2-litre X-type in September.

The 153bhp four-cylinder engine from parent company Ford’s Mondeo brings the number of Jaguar diesel options to five, with a sixth version soon to be announced in the form of the range-topping XJ saloon. The X-type 2.2D meets Euro IV emissions standards, averages 47.1mpg and produces 159g/km of CO2.

With peak torque of 265lb-ft, the X-type has been engineered for strong mid-range performance, and it comes with an overboost facility which liberates nearly 300lb-ft of torque for overtaking manoeuvres.

Prices for the saloon and estate will be announced nearer to its September launch.

The popularity of diesels in Jaguar’s line up has resulted in the 2.5-litre petrol model being dropped from the range. To mark its demise, Jaguar has launched a series of run-out special editions, all featuring more than £3,000-worth of optional extras. Prices for the 2.5 Plus, SE Plus and Sport Plus start at £25,995.
