Jaguar Land Rover (JLR) plans to double the size of the British engine plant where it produces its new modular in-house ‘Ingenium' engines.

The plan involves an investment of £450 million ($A940 million), bringing the total spend on the plant — opened last year — to about £1 billion. It is thus billed as the most significant new automotive manufacturing facility to be built in the UK in the last decade.

It is also a sure sign of JLR’s continued growth under the ownership of Indian giant Tata.

This latest big splurge will see the creation of a few hundred additional jobs in addition to the 700 staff already working there. JLR’s global workforce will soon top 40,000.

The Engine Manufacturing Centre in the British Midlands is to be responsible for producing Ingenium units for a wide range of JLR products across its three assembly plants. The company claims to be the biggest manufacturing investor in the UK.

The Engine Manufacturing Centre is one of Jaguar Land Rover’s four UK-based manufacturing facilities. Together with its R&D centers in Coventry and Gaydon, Jaguar Land Rover has invested £11bn in product creation and facilities, creating more than 20,000 new jobs in the last five years.

In the twelve months since opening (pre-expansion), the facility has moved from prototype production to full-scale manufacture with more than 50,000 engines coming off the line. The EMC expansion will grow its footprint to 200,000 square-metres.

The engine produced at present as the plant scale up is the 2.0-litre turbo-diesel used in the Jaguar XE and 2016 Range Rover Evoque. It will soon also power the Land Rover Discovery Sport, the all-new Jaguar XF and the Jaguar F-Pace.

The modular family will soon expand to include petrol-fired version/s, which will replace the current 2.0 turbo Ford unit used in a number of the company’s vehicles.
