Volkswagen is at the heart of the biggest car fraud story ever, but the likes of Mercedes and BMW will soon be involved. According to the latest on-the-road results from Transport & Environment (T&E), some Mercedes A, C, and E class cars as well as BMW's latest 5 series and Peugeot 308 cars are using up to 50% more fuel than their lab test results.
The problems that this is creating, is that the official numbers given by Volkswagen, Mercedes and BMW are different to the real-world performance numbers and this gap is becoming so wide that "it cannot be explained through known factors including test manipulations", reports Ademloos.be. Things have gotten worse in the last 15 years or so, where the official test results for CO2 emissions/fuel economy and real-world performance have increased from 8% in 2001 to a huge 40% on average for 2014.
The numbers are coming from T&E's 2015 Mind the Gap report, which takes a look at on-the-road fuel consumption by motorists and highlights what Volkswagen, Mercedes and BMW have been doing for years. These carmakers have been abusing the system, with EU regulators not closing the various loopholes that allow this to happen. T&E has added that without action, the gap will grow from 40% from 2014, to over 50% on average by 2020.
