Jaguar Land Rover has said unequivocally that it doesn't use technology to dodge diesel emission tests in the wake of the Volkswagen scandal.

The German marque is at the centre of a massive fallout after it admitted 11 million vehicles around worldwide are fitted with software designed to cheat emissions tests.

The car maker is facing deepening scrutiny after tests by US regulators forced it to admit cheating on the tests for nearly 500,000 vehicles, and authorities across the world launched further probes.

Some industry commentators have suggested the practice might be widespread – but Jaguar Land Rover told the Post that their vehicles do not use software of this kind.

A spokesman for JLR said: “Jaguar Land Rover does not use any ​emissions ​‘defeat’ software.

“Our latest cars are the cleanest ever and customers who buy vehicles from Jaguar Land Rover can be confident that they will be fully compliant with all EU and US emissions regulations; that they will adopt the latest technology to control emissions and they will be helping improve air quality and meet CO2 and emission targets.

“Jaguar Land Rover is committed to the development of the latest advanced technologies on both petrol and diesel cars to reduce emissions and meet all worldwide standards.

“Jaguar Land Rover has heavily invested in new clean diesel technology across our entire vehicle range. This includes the development of the new Ingenium engine (built in-house at our new £500m Engine Manufacturing Centre in Wolverhampton) and our advanced selective catalyst reduction (SCR) exhaust aftertreatment for NOx control which features on all 16MY vehicles.

“All Jaguar Land Rover EU6 diesel engines are equipped with Diesel Particulate Filters (DPF) AND Selective Catalytic Reduction (SCR).”

There are already plans to expand the Staffordshire i54 engine plant which has already created 1,400 jobs to cope with worldwide demand.

It was created with £500 million investment from JLR along with £10 million from the Government.

Volkswagen said discrepancies related to type EA 189 engines. It said: “A noticeable deviation between bench test results and actual road use was established solely for this type of engine.”

The company said it was “working intensely to eliminate these deviations through technical measures” with German and other authorities.

It added: “To cover the necessary service measures and other efforts to win back the trust of our customers, Volkswagen plans to set aside a provision of some 6.5 billion euros recognised in the profit and loss statement in the third quarter.”
