Jaguar has released more information on its new range of turbocharged and direct-injected ‘Ingenium’ four-cylinder petrol and diesel engines.
The Ingenium line will suit inline and transverse applications, which also suggests that front-wheel-drive Jags could be on the horizon.
Among the first production examples of the new family will be a 2.0 litre turbodiesel unit known as ‘AJ200D’, set to make its debut in the new XE range.
Jaguar says the AJ200D’s highlights include a 17 percent reduction in internal friction - compared to the current 2.2 litre diesel - thanks to the use of roller bearings on cam and balancer shafts.
Computer-controlled cooling is also featured, enabling quicker warm-ups and a faster heating of the cabin.
All engines in the range will have the same bore, stroke and cylinder spacing, with each cylinder measuring 500cc.
The new engine family also promises to be significantly lighter than the company’s current range, with savings as great as 80kg - depending on the specific engine.
All of this, Jaguar says, will lead to great efficiency and fuel savings, with the AJ200D in particular capable of returning consumption figures as low as 4.2 l/100km in the midsized XE sedan.
CO2 emissions of less than 100g/km are expected - although not in the more performance-oriented engines, which will make as much as 298kW.
The company also expects the Ingenium engine family to have a long life ahead of it.
"Being configurable and flexible are the two key strands of Ingenium's DNA because we have future-proofed our new engines from the outset," Jaguar Land Rover powertrain engineering director Ron Lee said.
"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."
Jaguar says it has so far tested the new UK-built engines over more than two million kilometres of real-world driving on public roads.
The new Jaguar XE is expected to be revealed later this year, with production to begin in mid 2015.
