You might think you know how polluting your car is from official figures. On-road tests will be more accurate
Finding your car’s true pollution would have been nearly impossible as recently as a few months ago. But now you can discover the true emissions – harmful and otherwise – pumped out of its exhaust pipe. It’s courtesy of a company called Emissions Analytics which tests cars’ real-world performance for emissions and economy.
By measuring their miles per gallon and pollution output on the road, rather than in a lab like the official figures do, Emissions Analytics can build up a picture of how cars really perform. Just as you’ve probably found out for yourself that your car’s real-life economy differs from that claimed by its manufacturer, so its carbon dioxide (CO2) output is different too. Now, as well as your car’s true output of nitrogen oxide , you can find its real carbon dioxide output, as well as its genuine miles per gallon in every day motoring.
Which were the worst cars for real CO2?
It’s not easy being a driver who wants to do their bit and buy a car with the lowest nitrogen oxide emissions. These NOx are harmful pollutants emitted by cars that are estimated to contribute to over 30,000 premature deaths a year in the UK. Information about a car’s NOx levels has been hard to come by as, for obvious reasons, vehicle manufacturers tend to advertise cars’ fuel economy or performance rather than the nasty particulates pumped out of exhausts.
But now a new website allows drivers to see just how polluting Britain’s most popular makes and model of car are when used in normal, everyday driving conditions.
The Volkswagen emissions scandal has rocked the car industry and prompted drivers everywhere to wonder if they can trust anything car makers tell them. The outrage was discovered in the US and involves a programme hidden in cars’ computers. This can tell when the vehicle is undergoing an emissions test. It then switches the engine to a mode where it emits less Nitrogen Oxide (NOx) to pass strict air quality tests. There are 11 million cars world-wide that could be affected. Here’s what British drivers need to know.

Car fuel economy is one of the things drivers complain about the most. It’s not that modern cars aren’t economical. They are. But car makers claim they’re much more frugal than is actually the case. The reason for the inaccuracy is all down to the way car economy is tested. But that is about to change. So, are we likely to see cars finally living up to their makers’ consumption claims?

Fuel consumption – and more specifically cars’ inability to their match makers’ claims – is one of the biggest causes for complaint among drivers today. Now new research shows that smaller cars are more likely to return fewer miles to the gallon than larger models. Continue reading
