months Ago, PSA Group announced that it would publish the consumption actual of several of their best selling models. More than their consumption real average consumption on the basis of a cycle of realistic driving. That time has come. We know that the cycle of type-approval NEDC european is not realistic, it does not respond to reality of the millions of european drivers and the car manufacturers know so well their variables, that adjust their cars to pass the “exam” with a note. PSA has broken with the european automobile industry with this move.
What is the cycle of consumption has been used, the PSA Group?
Since does not strange that some cars consume up to 50% more than the figure approved. The cycle NEDC european is not all realistic.
The giant French has partnered with the Ngo Transport & Environment (T&E) and France Nature Environnement (FNE) and hand-in-hand, have been subjected to three of their top-selling cars – the Peugeot 308, the Citroën Grand C4 Picasso and DS 3, all with diesel engine 1.6 HDi 120 CV – a new cycle of approval of consumption. This cycle has included 25.5 km of urban area, at 39.7 km of area extra-urban and 31.1 km of motorway. This cycle has been proposed for Transport & Environment, and all tests have been carried out on the outskirts of Paris.
To make it more realistic, the air conditioning was turned on and the car would simulate the existence of passengers on board, in addition to having to carry the added weight of the portable measuring system of emissions, hung behind the car. But no, we do not know exactly at what speed and over what time have circulated in the tests, which, moreover, have been carried out in an area not known for having large slopes. The surrounding area of Paris is rather flat, with the occasional gentle hill.
Bureau Veritas, have certified – as an independent agency – the reliability of the data collected in the tests.
even Though you have not explained how it has been such a driving cycle, the PSA Group asserts that this cycle of realistic has in the european project RDE “Real Driving Emissions” your source of inspiration. This project will lead to the disappearance in 2017 cycle NEDC, which will be replaced by a cycle called WLTC – more realistic with the use of the cars. The PSA Group has also compared the consumption data obtained from several surveys to some of their clients, who drive the same vehicles tested.
So have been the results:
|Citroën Grand C4 Picasso||Peugeot 308||DS 3|
|Consumption measured||5.6 l/100 km||5,0 l/100 km||4,9 l/100 km|
|Mean customers||5,5 – 5,7 l/100 km||5,0 – 5,1 l/100 km||5,1 – 5,3 l/100 km|
|type-Approval NEDC||4,0 l/100 km||3.8 l/100 km||3,6 l/100 km|
|Deviation over NEDC||+40%||+31,6%||+36,1%|
As you can see, in terms of more realistic circulation, cars consume at least 30% more than the figure approved. PSA has committed to publish before the summer a complete list of consumptions are realistic in their cars, in anticipation of the introduction of a new cycle of approval. A movement that we value very highly, and that in addition to providing transparency to opaque procedures, offers car buyers a data more realistic about the final consumption of the car.
