What's all this about?
Jaguar has developed a new range of high-tech diesel engines at a cost of £500 million, which is not an insubstantial investment. They're called Ingenium.
What makes them special?
They're all-aluminium units developed from a clean sheet of paper. That means they're very quiet, very smooth and very economical.
How so?
These 2.0-litre engines are low friction designs, have stiff cylinder blocks and twin balancer shafts to reduce vibration. The bit the inner geek is us likes best is the '0.5mm ovality on the injection pump drive sprocket', which is one of a suite of measures designed to keep the Ingenium engines quiet during operation.
And which Jags will I be able to find them in?
The first model they'll be shoehorned into is the all-new XE saloon, with two variants on offer. There's very little in them on the power/torque fronts, as one makes 163hp/380Nm while the other is modestly uprated to 180hp/430Nm. However, the former dips below the 100g/km mark for CO2 at 99g/km - meaning zero road tax - and combined economy in the XE is said to stand at 75mpg.
Are they Euro 6 compliant, then?
Of course, they couldn't be anything other. Also, two million miles of 'real-world testing' has gone into making these new powerplants and once the West Midlands factory is running at full tilt building them, an Ingenium will be leaving the line every 36 seconds.
