New cars, including the Mercedes A, C and E class, BMW 5 series and Peugeot 308, are now swallowing around 50% more fuel than their lab test results, new on-the-road results compiled by Transport & Environment (T&E) reveal. The gap between official and real-world performance found in many car models has grown so wide that it cannot be explained through known factors including test manipulations. While this does not constitute proof of ‘defeat devices’ being used to fiddle fuel economy tests, similar to that used by Volkswagen, EU governments must extend probes into defeat devices to CO2 tests and petrol cars too.
The system of testing cars to measure fuel economy and CO2 emissions is utterly discredited. This report analyses the gap between test results and real-world performance and finds that it has become a chasm, increasing from 8% in 2001 to 31% in 2012 and 40% in 2014. Without action this gap will grow to nearly 50% by 2020. It also looks at which models have been found to have the biggest gap between claimed CO2 emissions and real-world performance.
Unless you have buried your head in the sand over the last couple of days, you would have been hard pressed to miss the VW cheating scandal that has erupted in the United States. A tsunami of media stories have taken over the front pages of the FT, NYT, The Guardian, Le Figaro, Il Sole 24 Ore, to name a few.
Eco-driving technology that will save motorists €30 to €50 year today received the backing of MEPs who called for mandatory fuel consumption meters for all new cars, vans and trucks. The European Parliament’s environment committee overwhelmingly voted for the meters to be fitted and permanently visible in all new vehicles from 1 January 2019, leading to fuel efficiency gains of 2-3% per year.

In this report T&E analyses the reasons for and solutions to air pollution caused by diesel machines and cars – the worst of which, an Audi, emitted 22 times the allowed EU limit. In fact, every major car manufacturer is selling diesel cars that fail to meet EU air pollution limits on the road in Europe, according to data obtained by T&E. As a consequence, much urban air in Europe is not fit to breathe. The high levels of particles, nitrogen oxides and unburned fuel create a cocktail of harmful pollution. The effects are half a million premature deaths each year; a quarter of a million hospital admissions; and 100 million lost working days cumulatively costing over €900 billion.
Every major car manufacturer is selling diesel cars that fail to meet EU air pollution limits on the road in Europe, according to data obtained by sustainable transport group Transport & Environment (T&E). All new diesel cars should have met the Euro 6 auto emissions standard from 1 September – but just one in 10 tested complied with the legal limit.
The use of cheap, ineffective or poorly configured exhaust treatment systems is one of main reasons why the majority of new diesel cars fail to meet EU air pollution limits on the road. That’s according to the latest research by the International Council on Clean Transportation (ICCT), which last year found that 13 out of 15 modern diesel cars did not achieve the Euro 6 limit in real-world testing.
A consortium of car manufacturers, suppliers and repairers has, in an attempt to hide the fact that a typical diesel car emits 10 times more nitrogen oxides than an equivalent gasoline car, launched a new website. Its content ignores the inconvenient truth that new diesels can’t reach the limits agreed back in 2007 without fitting new technology. This briefing provides six facts about diesel cars that the industry would rather the public didn’t know.
