With the new Ingenium diesel engines driving the rear wheels, the aluminium-intensive XE is the most fuel-efficient Jaguar yet, with CO2 emissions from just 99g/km.

The Ingenium range is produced at the new £500 million, 100,000m2 Engine Manufacturing Centre in the West Midlands in the UK. Engines will come off the fully flexible lines at rates of up to one every 36 seconds.

Starting from a clean sheet meant that Jaguar's powertrain engineers could make the Ingenium engines as light and efficient as possible, and deliver the blend of power, torque and smoothness customers expect. These state-of-the-art engines were proven over 2 million miles of real-world testing.

"The new generation of Ingenium diesel engines are wholly designed and manufactured in-house. No opportunity has been missed in ensuring their design is right on the cutting edge of technical advancement." - Ron Lee, Group Chief Powertrain Engineer, Jaguar

The low friction, all-aluminium units have stiff cylinder blocks and twin balancer shafts to ensure inherently low levels of vibration. Details such as the acoustic sump cover, decoupled injectors, and 0.5mm ovality on the injection pump drive sprocket contribute to the Ingenium's exceptional quietness.

The new XE will feature two versions of the 2.0-litre Ingenium diesel. The first, rated at 163PS/380Nm, delivers benchmark efficiency figures of 75mpg and 99g/km CO2 without any compromise to launch performance or mid-range acceleration. The 180PS/430Nm variant has one of the highest torque outputs in the class.

Ingenium diesels meet Euro 6 are as clean as they are efficient. Variable exhaust valve timing shortens the catalyst light-off phase and also improves diesel particulate filter (DPF) regeneration. The cooled low-pressure exhaust gas recirculation (EGR) system reduces combustion chamber temperatures, inhibiting NOx formation. Selective catalytic reduction (SCR) technology cuts NOx emissions to very low levels and the new XE has been engineered to meet the most stringent global regulations.

The Ingenium diesels will be joined at launch by powerful, efficient, direct-injection petrol engines: turbocharged 2.0-litre four-cylinders and the outstanding supercharged 3.0-litre V6.
