Jaguar on cutting edge of technical advancement

With the new Ingenium diesel engine driving the rear wheels, the aluminum-intensive XE is the most fuel-efficient Jaguar yet, with carbon dioxide emissions from just 109g/km.

Ingenium range is produced at the new R8.9 billion, 100,000m2 engine manufacturing centre, West Midlands in the United Kingdom. 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 two 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 power-train 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 a 2.0-litre Ingenium diesel. Rated at 132kW/430Nm, it delivers benchmark efficiency figures without any compromise to launch performance or mid-range acceleration andhas one of the highest torque outputs in the class.

The diesel meets Euro 6 standards and is as clean as it is efficient. Variable exhaust valve timing shortens the catalyst light-off phase and 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 diesel engine will be joined at launch by powerful, efficient, direct-injection petrol engines turbocharged 2.0-litre four-cylinders with power of 177kW and the outstanding supercharged 3.0-litre 250kW V6.
