we have Already made to the idea that the cycle european type approval (NEDC) does not represent neither the conduct of the europeans, nor the consumption of modern cars. most of The manufacturers make traps -legal – at the time of standardization, leaving much of the reality.
But there are always exceptions, and the German magazine has named. In the extensive test of 275 kilometres on roads open to traffic, manufacturers are more honest with their consumption are two japanese, two britons and a German. Outside of the labs, the thing changes.
have been tested 600 cars launched since 2013 until today
cars Jaguar slowed to an average of 11.4% of the values approved, which means that were fewer manipulations of the evidence, without rush the flexibility of regulation. The conclusions can be extrapolated to Spain, as the data of approval are valid for the entire EU.
Jaguar is a brand more honest, according to the German magazine
Another brand in the same group, Land Rover, has also been left with consumption real below the approved, with a deviation of 3.4%. Porsche does it better, by lowering the consumption approved by 4.8% in the real world.
In regards to the japanese manufacturers, leading Subaru with a reduction of 6%, followed by Infiniti with a reduction of 5.2%. I must say that these manufacturers do not have a focus entirely european, but global, and bother less on manipulating the evidence.
Another japanese manufacturer, Toyota, deviates only 0.8% of the figures specified, which is practically offering consumption honest. By contrast, according to Transport & Environment, the models of this brand, it is less deceptive to the consumer, while the deviation announced is superior. If you look at the chart.
According to Transport & Environment, the results can be much worse
We now turn to the part of the suspended. The following manufacturers have obtained consumption actual above approved, sadly something standardized. It is not surprising that the europeans have the largest deviations:
These data are quite condescending, if we compare them with those offered by T&E. If you are facing the consumption data database of users -as Spritmonitor – deviation of consumption and real approved is even bigger.
On average, there is talk of a 40% diversion to new models launched in 2014. Finally, it is worth remembering that the difference in consumption implies the same level of percentage deviation in emissions of CO2, because consumption rises in the same proportion.
