A long-standing problem is that what automakers show as data about fuel consumption in catalogs and advertisements are usually not appreciated by real-time use. Over the past 20 years, factories have received more and more advanced vehicles for official test measurements, which has led to a steady decline in consumption values in type approvals and which are lagging behind in practice. The European Transport and Environment Association (T & E) concluded in a new investigation that the scams actually committed in legal terms have caused harm to consumers and the environment since 2000.
In the past 18 years, the European Union would have left behind less than € 149.6 billion of cars in petrol stations if their cars were included in the data consumption of the catalog.
In Hungary this value can amount to EUR 1 billion, which translates to at least 250-300 billion losses when converted to the forint. The map below shows that the problem is most affected by Germany in the EU, which is certainly not surprising given the number of people and cars.
According to the study, the differences between the official measurements and the consumption values in real use increased dramatically between 2000 and 2017. Around the turn of the century, only about 9% of the average car could be found in comparison with catalog data. However, this difference was 17% in 2008 and 42% last year! All of this suggests that factories have increasingly used the weaknesses of test score rules over the years. Approximately 16 percent of the surplus consumption calculated over the last 18 years was therefore generated in the EU last year. Hungary received EUR 170 million, or about 55 billion forint.
According to decision-makers of the European Union, the situation will improve in a few years around the worldwide new measurement system (WLTP).*Global test procedure for harmonized light vehicles), resulting in much more realistic measurements during the tests. From September, only new cars with a fuel consumption certificate issued under WLTP may be sold in the EU, while the introduction of newly developed models since September last year is a condition. The shift has turned the life of the car upside down, for example, Volkswagen does not sell certain types of cars at the beginning of 2019 because it does not have enough capacity to activate new type approvals.
According to the above study, however, WLTP still has too much room for misleading measurements on car manufacturers, which is why it works together. In addition to false data, not only consumers are overwhelmed, but also legislators who set the limit values for the environment by taking into account official consumption figures. Experts say that it is possible that the manufacturers have been put together in the old tests and then increased the consumption of the tested cars during WLTP tests. So when they release the type certificate on WLTP basis, they can reduce their official consumption data without technical innovation.
It is estimated that the new measurement system will underestimate real consumption data by 23 percent by 2020, while the same percentage would be 49 percent if the old procedure could be used by factories. The research by Peugeot-Citroen and T & E suggests that in the combined WLTP measurement cycle*This gives collected data on road, city and highway traffic. overclocked highway and highway speeds tests at the expense of urban retreat. So your new test data is expected to be closer to reality, but those who are really interested in consumption will be worthwhile reviewing the real world experiences on sites like Spritmonitor.
