Jaguar Land Rover vehicles undergo independent emissions testing

Jaguar Land Rover has become the first OEM to submit a selection of new cars from its range for independent on-road emissions testing and inclusion in the Air Index. Developed with the goal of further informing car buyers and legislators, the Air Index uses an A-to-E rating to show the difference in vehicle emissions.

Following independent testing on the JLR range, the Air Index ratings system awarded the auto maker’s latest diesel engines an A-rating for NOx emissions. Each vehicle rating is based on at least two independently sourced cars, over three separate tests, including at least five 10km-trips conducted on paved roads, using onboard PEMS testing equipment.

Massimo Fedeli, co-founder and operations director, Air, said, “The Air Index provides easy to understand, at-a-glance information on actual vehicle emissions, from independent testing to help consumers compare vehicles when making buying decisions.

“One of the key things to observe from this set of Air Index ratings is that perceptions of the emissions produced by particular vehicle types, such as SUVs, can be very misleading. The perfect example is the Land Rover Discovery, which produced NOx emissions 20 times lower than a diesel Renault Clio supermini.”

Rawdon Glover, managing director at Jaguar Land Rover UK, added, “The performance of our vehicles on the Air Index reflects Jaguar Land Rover’s investment in class-leading technology and its hard-working, talented engineers. These tests clarify that not all diesels are equal, and not even all Euro 6-approved diesels are equal. As the tests have shown, a diesel SUV can be extremely clean.”
