Looks like saying the upcoming Jaguar XE will use aluminum extensively is a huge understatement. Even the brand new diesel engines powering this sedan will be carved out of this lightweight metal.

Called Ingenium, the new family of Jaguar diesel engines will initially be launched in two versions.

The British company said with the new Ingenium diesel engines driving the rear wheels, the aluminum-intensive Jaguar XE will be the most fuel-efficient Jaguar yet, with rated CO2 emissions starting at 99g/km.

The Ingenium range is produced at the new 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, said Jaguar.

Starting from a clean sheet for this new family of engines meant that Jaguar’s powertrain engineers could make the Ingenium engines as light and efficient as possible, said the company, and deliver expected power, torque and smoothness. These new engines were proven over two million miles of real-world testing, added Jaguar.

“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,” said Ron Lee, Group Chief Powertrain Engineer, Jaguar

The low friction, all-aluminum units are said to 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 oval shape of the injection pump drive sprocket are said to contribute to the Ingenium’s exceptional quietness.

The company added the new Jaguar XE will rely on two versions of the 2.0-liter Ingenium diesel. The first will deliver benchmark efficiency figures of 75 mpg (imperial) and 99g/km CO2 without any compromise to launch performance or mid-range acceleration. The second version will have one of the highest torque outputs in the class. Exact power figures have not yet been released.

Ingenium diesels already meet Euro 6, added Jaguar. 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 for the XE launch by direct-injection gasoline engines: turbocharged 2.0-litre four-cylinders and the supercharged 3.0-litre V6. No word yet on the availability of the diesel units in North America.
