STEFANO FUGAZZI (ABC ECONOMICS) / The emission-fixing issue that has engulfed Volkswagen in the US could extend to other companies, one of the investigators involved in uncovering the scandal has told The Guardian newspaper. If confirmed, this would nonetheless be the “worst kept secret” in car manufacturing.
In recent years a number of focus groups and non-governmental bodies published reports highlighting the car manufactures “tweaking” the official emission figures.
In 2013 the non-governmental organisation Transport & Environment (T&E) published a dossier called “Mind the gap” which reported motorists’ feedback on fuel consumption.
Shockingly, the report revealed the gap between carmakers’ claims about fuel efficiency and real-world fuel consumption has widened from an 8% difference in 2001, to 31% in 2013.
Why the gap? According to T&E, the “discrepancies” in values are attributable to carmakers producing specially-prepared prototype vehicles for the obsulete test and pay testing services to help them optimise the results.
Below a link to the 2013 T&E “Mind the gap” report which highlighted how car manufacturers, including Volkswagen, cheated on their emission figures.
Mind the Gap! Why official car fuel economy figures don’t match up to reality
Executive summary: This report provides new evidence and understanding on why there is a growing gap between the official fuel consumption and CO2 emissions of new passenger cars and vans, and that which is achieved by the same vehicles on the road. It demonstrates that the current (NEDC) test is outdated and unrepresentative of real-world driving and current vehicles, and that lax testing procedures are allowing car-makers to manipulate the official tests to produce unrealistically low results.
