Jaguar Land Rover has revealed a new series of low-emission petrol and diesel engines. Known as Ingenium, the units can be adapted to run on petrol or diesel and are said to be significantly cleaner and more efficient than the firm’s current engine line-up.

The first version will be a 2.0-litre diesel, which is smaller than the company’s current lowest-capacity 2.2-litre diesel and will go into the forthcoming upper medium Jaguar XE, which will rival the sector stalwart BMW 3-series.

Figures have yet to be revealed, but the firm claims the new engine will have 17% less friction than the outgoing 2.2-litre unit, which will increase efficiency and supposedly render it “one of the most efficient 2.0-litre turbodiesels in its segment”.

The Ingenium units will be scalable to allow them to be produced in different sizes, with different power outputs and be used across the model range. The firm added that they will be able to pair up with hybrid drivetrains and “new advances in engine technologies as they become available”, which suggests lower-emitting plug-in versions of its products may be on the way.

They will also be compatible with multiple transmissions and rear- and four-wheel drive systems.  
Production of the new engines will begin early next year.
