AIR Index emission tests reveal Land Rover vehicles as an 'A' rating: the highest possible rating
Added: 12 March 2019
In recent news, a newly launched AIR Index - an independent emissions testing procedure - revealed the results of a range of manufacturer vehciles, measured against a rating system for NOx (Nitrous Oxcide) emissions. Amoungst the vehicles tested was an 18MY Land Rover Discovery 3.0 TD6, which was revealed to fall in the highest possible rating in the NOx test. The 'A' rating has gained considerable coverage in the media, due to assumptions leading consumers to believe a large SUV such as the Discovery, would be amoungst the lowest rated vehicles in the test.
Having said that, following the announcement last year that the WLTP (Worldwide Harmonised Light Vehicle Test Procedure) - providing more accurate fuel efficiency ratings for petrol, diesel, eletric and hybrid vehicles -, would replace the previous NEDC (New European Drive Cycle) standard: Land Rover were confident that "new figures will simply better demonstrate the real-world experience that our engines and powertrains provide".
AIR also published test results on the 180hp 2.0 litre diesel Ingenium 4WD versions of the outgoing Range Rover Evoque and Land Rover Discovery Sport. Both vehicles also achieved an 'A' rating in the test, achieving some of the lowest NOx emissions of any car on sale today.
As a brand, this is an outstanding achievement and will help Land Rover continue to reduce confusion over the cleanliness of diesel engines: caused by a focus on older diesel engines and their place on our roads. These debates often fail to highlight the difference between these older diesel combustion engines and the most recent Euro 6 (EU6)* engines which were introduced in 2015. These new figures from AIR Index will help outline Land Rover's outstanding capability, innovative technologies, and award winning design.
"Land Rover vehicles will remain a showcase for the finest in design and engineering"
Land Rover aspire to independently test every single nameplate, in order to reassure customers that they have the lowest possible NOx emissions. In the mean time, Land Rover states that their diesel vehicles offer more torque. Its power is ideal for motorway driving, conquering off-road terrain and towing. Customers driving 12,000 miles a year or more, are likely to find diesel to be the most cost-effective choice. The higher energy density of the fuel and the way energy is released during combustion, means diesel can offer a greater return on mileage. Land Rover’s latest diesel engines are EU6 compliant; their pollutant emissions are comparable to petrol engines, but with CO2 emissions that are 20-25% lower.
Since 2006, Land Rover diesel vehicles have also been fitted with particulate filters and catalytic converters, removing 99% of all particulates from the exhaust. When it comes to reduced NOx emissions, Land Rover diesel vehicles employ Selective Catalytic Reduction (SCR) to eliminate up to 92% of nitrogen oxide (NOx) emissions from the tailpipe. Land Rover's Selective Catalytic Reduction (SCR) system features exhaust aftertreatment solution (e.g. Diesel Exhaust Fluid (DEF) or AdBlue®) to chemically convert NOx into harmless nitrogen (N2) and water (H2O).

* Euro 6 (EU6) is a piece of European legislation aimed at making cars more environmentally friendly by limiting their exhaust emissions. The legislation sets restrictions on emissions, including nitrogen oxide (NOx), particulates and hydrocarbon gases that may be emitted per mile by a road vehicle. All of Land Rover's new vehicles are EU6 compliant and are even exempt from the Ultra Low Emission Zone daily charge (ULEZ) proposed by Transport for London in the UK.
