On previous occasions I have been told that the difference between consumption and real approved lately does nothing but climb. Cars are reducing their consumption in the paper, after optimizing the laboratory conditions in which to carry those tests out. Then, on the road, the driver does not notice these developments.
In the report, for the year 2014, we have compared the consumption of officers of various models and have been faced with the consumption declared by those users in Spritmonitor.de. This public platform stores data of actual consumption of more than 500,000 cars, with contributions from the users themselves.
The model that represents PSA Peugeot Citroen is the Peugeot 308, with a discrepancy of close to 50%. In other words, the car actually consumed almost 50% more what it says in the technical sheet, with the consequent damage to the driver (more fuel costs), the environment (more emissions), and for the Treasury (loss of taxes for emissions).
In the last report of T&E we found out that the Peugeot 308 goes wrong standing, but worse come several models of Mercedes-Benz, above the 50% discrepancy
¿How to explain these differences?
on the one hand we have the abuse of the manufacturers of all the flexibility that is the regulation of the cycle of type-approval NEDC, which was established in 1992. This driving cycle has nothing to do with the driving style of the europeans today, and that has the cars to the very tip of gas, with a requirement that is ridiculous. They announce consumption very low, especially with engines tight.
on the other hand, some manufacturers may be resorting to the same trap that Volkswagen with the TDI engines CR EA189: if the car detects an approval test, the emissions are kept at bay. Transport & Environment does not go so far, but argues for a greater control until the new cycle of approval, WLTP in 2017.
The PSA Group has announced in a press release that their cars do not cheat, and that comply with the european legislation. That means that deny flatly that there schedules hidden for the cars are made clean as they are approved. But they will go beyond.
In our test of consumption, the 308 BlueHDi automatic 120 HP spent 5.3 l/100 km of diesel. Approvals 3.5 l/100 km, that is to say, the deviation is almost 50%. It is the same complaint T&E
The results will become available from spring, and their best selling models
The manufacturer is defending itself by arguing that they are working to reduce emissions with their engines tricilíndricos Puretech gasoline, the BlueHDi diesel with injection of urea, platforms, lightened or gearboxes optimized. Well, the results demonstrate that these advances have not been sufficient.
For most manufacturers, the consumption real their cars are taboo. They give the official figures, as the European Union is forcing them. The actual data are less important in the face of the user, who can feel, of course, cheated.
In ideal conditions you can get consumption of scandal, but they are not representative of the actual driving
manufacturers sometimes boast of the opposite: that consumption can be lowered even below the approval. Without leaving the PSA, we have the record 2.85 l/100 km for the Peugeot 308 1.2 Puretech 130 HP. That record was achieved in ideal conditions, and is practically the minimum energy consumption possible for that engine.
is Not bad, no, but no one drives as well. The approval is 4.6 l/100 km, and with an increase in the reality of nearly 50%, since we are going to more than 6.5 l/100 km Is a lot of difference. The average customer does not get to 1,800 miles per tank, but a lot less, even half.
it Would be very good for the automobile industry, since it has been so clear lately, that PSA is not the only manufacturer to uncover her nakedness. Consumers have a right to know that his brand new car might not consume less than the model it replaces, and how much it will cost that every year.
The response of transparency of the PSA arrives late, but in any case, it is worthy of praise. At least have been the first to make the step.
