EQUA index provides free real-world fuel economy figures for more than 60,000 cars

Emissions Analytics has launched a new EQUA mpg index which provides real-world fuel economy data for more than 60,000 car models.

The project is the largest of its kind in Europe and data is free to access at the EQUA index website.

Research by Emissions Analytics has found that in 2016 the average shortfall between official and real-world fuel economy results has reached 29%, with some vehicles more than 40% adrift.

Over the last two years the average real-world fuel economy of cars fell for the first time ever, down to 40mpg from 41mpg. Diesel cars were worst affected, falling from 45mpg to 42mpg over the same period – likely due to downsized engines which need to be worked harder.

To compile the data, Emissions Analytics has tested hundreds of cars in standardised, on-road conditions. The programme joins the growing range of tools from Emissions Analytics which cover emissions of nitrogen oxides and poisonous carbon monoxide.

    I have doubts as to the accuracy of Equa's published results. The PlugIn Prius is showing as identical mpg to the non PlugIn Prius (ie. 48.7 mpg). My factual results were 237mpg for the PlugIn Prius (average over 4 years) and 53.0 for the non PlugIn version (over 3 years). I question if they even tested a PlugIn Prius.

    Not exactly "filled with confidence" in their reporting when their advert shows a 1.6 Astra Petrol that has 197bhp?
