Audi CEO Bram Schot, “We can’t be with our Performance satisfied. Audi has excellent products on the market, but as entrepreneurs we do not have passed, especially the WLTP as the ultimate stress test.” Many German manufacturers like Audi, the transition from the years of current consumption cycle NEDC (New European driving cycle), WLTP (World Light Vehicle Test Procedure), time 1. September 2018 managed. Because of the relatively small piece of the Audi had to be pushed to pay the Check, the powerful eight-cylinder engine to the rear – however, even nine months after the WLTP-introduction of eight-cylinder can not be offered versions of the models A7, A8, Q7 or Q8.

To a large variety of models

Audi (and other German manufacturers), was fatal to that of most engines, a gigantic number of variants exists. So there’s the two-liter four-cylinder gasoline engine of the type EA 888 in numerous Audi models, from the small A1 to the mighty Q7. With a manual gearbox, with DSG, with or without 4×4 and in various combinations of wheels and bodies. Since almost every combination has a different weight, spec, and thus the fuel consumption, is to coordinate the effort, all of these variants on the new WLTP cycle, huge.

Test takes twice believe as long

but, the “misery of the development divisions” will soon have an end, is mistaken. Because the next stage of the WLTP is announced. This so-called “Second Act” covers from the fall of a modified Version of the mandatory evaporation tests (EVAP), in almost all engine-transmission versions are required to certify the vehicles. This is to check how much Fuel evaporates in the surrounding air, if the vehicle is not moved for 48 hours. The Test is not a new one; previously, the test phase, however, amounted to only 24 hours. This means that The new Tests take twice as long as before.


delivery to Speak with developers of the car companies, chatting of this, that the new Tests per car does not need to be under 14 days. Some models provide the elaborate technical inspection in the first place after three weeks. Accordingly, therefore, was not only the personnel, but also the logistical effort. “Compared with 2018, however, we are confident that we can mitigate the impact of the second stage significantly,” said Christian Dahlheim, Volkswagen sales chief. “However, we cannot exclude temporary restrictions for some of our models in the second half of the year only.” Similar to tönts at Mercedes. Daimler-sales Executive Britta Seeger talks to the “automotive week” is also concerned that the process could lead to a supply for certain key models of the brand delays. The new rules had only been at the end of November in their final Form, be published, required new types of vehicle but already since the beginning of the year compliance.

No free testers

Audi, BMW, Mercedes, VW and co. have their test engineers have long been in a Three-shift, to their vehicles as quickly as possible to the new, resharpened requirements. As of 2018, but it is also in 2019 is hardly possible to get hold of in Europe, any free test test. The subjects stand in front of the chambers of the proverbial snake, before it then goes to the RDE Test (Real Driving Emissions) on the road.

Not all of them, however, have problems

Other manufacturers, for example Hyundai and Kia, Nissan and Renault, Mazda, Volvo or Toyota – are not affected as much by this problem. You have, in most cases, a smaller model portfolio and, above all, significantly less variants. These manufacturers, that they offer only two to three main engines, with four cylinders and not more than a dozen three-to eight combustion chambers and different versions of Transmissions, and body styles. Sometimes less is more.
