Diesels and SUVs cleaner than superminis

Jaguar Land Rover is the first cart maker to independently rate its product’s on-road emissions, using testing and rating for inclusion by the AIR (Allow Independent Road-testing) Index.

The AIR Index was created to inform and empower car buyers and city policy makers with a simple A-to-E colour-coded rating showing the difference between clean and dirty vehicles. The AIR Index uses tests according to the CWA17379 standardised methodology which ensures that the results are independent, comparable and can be used as the basis for a legal framework for vehicle policies.

Perhaps surprisingly, the ratings reveal that the new diesel engines in the Jaguar and Land Rover cars tested are some of the cleanest models for NOx emissions on sale in Europe.

The cars tested were:
Jaguar E-PACE HSE 2.0l
Land Rover Discovery Sport 2.0l
Range Rover Evoque TD4 2.0l
Land Rover Discovery 3.0 TD6HSE

Massimo Fedeli, co-founder and operations director, AIR said: “The evidence shows that their latest engines are extremely clean, with all of the four models tested achieving the AIR Index A rating, which means that they produce the lowest levels of NOx emissionsin urban driving.”

One interesting result is that the test help disprove the idea that any one type of vehicle is automatically cleaner than another, for example a SUV can be much cleaner than a city car, and the Land Rover Discovery actually produces NOx emissions 20 times lower than that of a diesel Renault Clio
