A new database of 'real-world' emissions figures aims to help car buyers make more informed choices, with VW Group cars dominating the top positions

Drivers can now find out how polluting cars are in "real-world" conditions, thanks to an online database with independent tests of 440 of the most popular models. And surprisingly, given last year's emissions scandal, VW Group cars perform best.

The information is contained on the EQUA Index, a new database conceived by independent testing company Emissions Analytics, with the top six diesels cars that meet the latest Euro 6 emissions standard all from Volkswagen or its sister brands Audi and Skoda.

In addition, five of the least polluting cars designed to meet the older Euro 5 diesel standard, including the top two, are from the VW Group. And the German firm’s models top the Euro 6 petrol, Euro 5 petrol and Euro 6 hybrid categories.
