Jaguar Land Rover Ingenium engines WILL be class-leading, promises firm

Jaguar XE Ingenium engineJaguar Land Rover has announced its new Ingenium 2.0-litre four-cylinder turbo engine family will begin production in early 2015 and deliver class-leading CO2 emissions, refinement, power and torque. 

The engines have, revealed Jaguar Land Rover engineers at a Gaydon briefing, been thoroughly benchmarked against dozens of rival engines in order to achieve this – and CO2 is key. The current CO2 champions of the turbodiesel junior exec class are the Audi A4 2.0 TDI ultra and BMW 320d EfficientDynamics, both on 109g/km CO2 (that’s 67.3mpg).

Jaguar claims the new Ingenium turbodiesel-engined XE saloon will step significantly ahead of both – delivering the first sub-100g/km CO2 non-hybrid junior executive car on sale. That equates to 74.3mpg.

The firm’s confident it will achieve this because it has already got near to 100g/km in initial compliance testing. It hasn’t yet dipped below the 100g/km CO2 barrier but is certain to before production car certification is required.

Jaguar Ingenium: the 250hp 2.0-litre turbodiesel?

The new Jaguar XE 2.0 Ingenium will also boast class-leading refinement, promises Jaguar – and higher-spec versions will produce class-leading levels of torque and horsepower, too. The current 2.0-litre turbodiesel power leader is the BMW 325d, on 218hp and 332lb ft of torque.

Jaguar suggests the high-power Ingenium delivers similar power to its 3.0-litre V6 diesel, indicating at least 240hp. The suggestion that there’s some overlap between 2.0-litre and 3.0-litre turbodiesels means 250hp could be on the cards…

All Ingenium engines will feature turbochargers, high-pressure direct fuel injection, variable valve timing and engine stop-start. The high-power diesels are likely to feature twin turbochargers: Jaguar appears to have ruled out ‘twincharger’ supercharger/turbocharger solutions, with engineers arguing its twin-turbo solution delivers similarly instant low-rev response.

Indeed, Jaguar is confident the Ingenium engine’s transient response will be best in class.


There will be dynamics benefits too, adds the firm. Despite delivering similar performance to the 3.0-litre V6 diesel, the Ingenium four-cylinder weighs a hefty 80kg less. This will pay dividends for ride and handling, front-wheel traction and overall vehicle dynamics and response.

Land Rover will benefit too: the Ingenium engines will also go in the new Land Rover Discovery Sport. Both Jaguar and Land Rover engines will be surprisingly similar, despite the differing needs of the brands – key changes can be counted on one hand, said an engineer. Yes, he revealed, the Jaguar engine is as wade-proof as the Land Rover motor…
