Ingenium range of engines to start production next year and will be used in the upcoming Jaguar XE

Jaguar Land Rover has revealed new details on its family of lightweight four-cylinder diesel and petrol engines, which will enter production in January 2015 and be fitted first into the Jaguar XE.

The new powertrain family weighs up to 80kg less than the firm's current engine offerings, while also improving performance and reducing CO2 emissions.

All engines in the range share the same bore, stroke and cylinder spacing, with each cylinder offering 500cc. JLR says the Ingenum family offers the "configurability and flexibility around which smaller or larger engines can quickly and efficiently be developed" in the future. 

Autocar understands that a three-cylinder spin-off unit is a direct possibility and a straight six engine is ‘theoretically’ possible. The engine family can be used for front-drive, rear-drive and all-wheel drive.

Both diesel and petrol variants will be equipped with turbochargers, with all engines sharing common components and calibrations - thus allowing JLR to react more quickly to changes in demand. All engines will also get direct injection, variable valve timing and stop-start technology.

The first engine from the new family to go into production will be a 2.0-litre turbocharged diesel - dubbed AJ200D. The company says that friction in the unit has been reduced by 17 per cent compared to the current 2.2-litre diesel engine.

Key to reducing that friction is a number of technologies, including computer-controlled oil and water pumps, cam followers running on roller bearings, a roller-bearing equipped balancer shaft and electronically controlled piston-cooling jets.

The firm's director of powertrain engineering Ron Lee said: "Being configurable and flexible are the two key strands of Ingenium’s DNA because we have future-proofed our new engines from the outset. Ingenium will be able to accept new advances in fuel, turbocharging, emissions, performance and electrification technologies when they are ready and accessible to be deployed.

Our Verdict

Jaguar XE

Jaguar's first attempt at a compact exec saloon is good - very good. But can the XE hold off the BMW 3 Series and Alfa Romeo Guilia to retain its crown?

“We were able to design Ingenium in this way because we had the rare opportunity to start the project with a clean sheet of paper. We weren’t locked into any of the usual restrictions that force engineering compromises because we had no existing production machinery that would dictate design parameters, no carryover engine architectures to utilise and no existing factory to modify."

JLR says that the new range has been tested on more than two million miles of real roads prior to reaching production. The engines will be built at the company's new Engine Manufacturing Centre near Wolverhampton - which forms part of a £500 million investment by JLR.

On the upcoming XE, which is destined to rival the BMW 3-series, the various Ingenium engines will, at one end of the scale, allow the car to travel at over 186mph and, at the other, return CO2 emissions of less than 100g/km. High-performance versions with over 400bhp are also planned.

It is understood that the new Land Rover Discovery Sport will also get the option of the Ingenium engine range, although not immediately from the new model’s launch, which is expected before the Ingenium engine plant begins full production.

80kgs reduction! That doesn't sound right!

9 July 2014
It will be interesting to see the power delivery characteristics of the 400 BHP version of this engine, with me guessing that Jaguar will use both Turbo and Supercharging to give it a massive spread of torque and that it won't be a laggy all or nothing screamer as that would be Jaguar at all.

9 July 2014
So if the cylinder displacement is fixed at 500, and threes and sixes are 'possible', then this 'family' of engines are all two litres? Not much of a family then, more a lone parent. How will Ingenium replace the Ford V6's and 8's, or will JLR keep buying these in? PS. Silly name. Are they made from Mag(ic)nesium?

9 July 2014
With a fixed cylinder capacity of 500cc, the I3 would be 1.5, I4-2.0, I6-3.0 - there's no technical reason why they can't build a V6-3.0 or a V8-4.0.

Each engine will be built with a wide range of power outputs - and will have diesel and petrol versions - they're some family

Seem like all the "premium" brands (BMW, Mercedes, Volvo ) are going in the same direction.

One interesting figure will be the relationship between bore and stroke, a wide bore - short stroke combination, allied with forced induction, could produce some serious BHP figures.

Computer controlled oil pump? not asking for trouble in any shape or form!

10 July 2014
Nothing wrong with that. Every modern car is computer controlled.

Modern electronics are getting more and more sophisticated. The wiring looms are now going fibreoptic as they are just too big.

If your ECU goes pop then your car will just die.

What's more encouraging is the fact they have done 2 million miles on the road. Not bench testing on various loads. There are some talented engineers in this country and I hope this turns out to be a world beater.....especially as I will order one if it is :-)

You probably already have an electric/computer controlled fuel pump; how many times has that let you down lately?

10 July 2014
How much part sharing is there between the petrol and diesel engines? I'm guessing the block is being shared, but what about the internal components? This looks like a very interesting range of engines, but the more I read about the complexity of modern engines the more the comparative simplicity of an electric vehicle appeals (putting aside battery issues for a moment).
