The Ingenium range is produced at the new £500-million, 100,000 m² 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; the engines were proven over 2 million miles (3.2 million km) of real-world testing.

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 0.5 mm ovality on the injection pump drive sprocket contribute to the Ingenium’s quietness.

The Euro 6 compliant engines features variable exhaust valve timing to shorten the catalyst light-off phase and also improve diesel particulate filter (DPF) regeneration. The cooled low-pressure exhaust gas recirculation (EGR) system reduces combustion chamber temperatures, inhibiting NO_x formation. Selective catalytic reduction (SCR) technology—the XE is the first Jaguar to use SCR—cuts NO_x 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 direct-injection gasoline engines: turbocharged 2.0-liter four-cylinders and the supercharged 3.0-liter V6.

Full details and technical specifications of the Jaguar XE range will be released at the Paris Motor Show.
