H Background: The New European Driving Cycle (NEDC), which is now almost 20 years old, has been criticized for almost as long because it was not practical and because it was also a playground for legal tricks by car manufacturers. In fact, it was purely a laboratory value that gave car buyers up to 40% lower consumption values ​​than could be achieved even with the most moderate driving style.

Consumption increases on paper, vehicle tax in real terms

Therefore, the introduction of the much more demanding WLTP (Worldwide Harmonized Light-Duty Test Procedure) is actually overdue and welcome. But more realistic consumption values ​​mean that these are now also significantly higher on the registration papers - not in practice. Because practically nothing technically changes on the engines of most car models as of the cut-off date.

But for the CO2-dependent amount of vehicle tax (€ 2.00 per gram of CO2 per km above the tax-free Limit value of 95 g /km) is exactly the CO2 paper value (g /km) entered in the registration certificate Part I in field V.7. It is added to the displacement-related 'base amount' (gasoline engine: € 2.00 per 100 cm³ or part thereof, diesel engine: € 9.50 per 100 cm³ or part thereof).

73.9 percent more vehicle tax

On average, according to experts, paper consumption values ​​increase by around 20 percent. But depending on the model, it can be more. In addition, the relationship between the base amount and the proportion of CO2 differs depending on the type. This leads to the curious situation, for example for a Peugeot 508 1.6 Pure Tech 180 (Diesel), which was released on August 30th. In 2018, the vehicle will be registered for the first time, and the amount for the same car that will be registered one day later will increase to € 160, as the ADAC has calculated. This corresponds to an increase of 73.9 percent.

Because the motor vehicle tax is manageable in absolute terms, relatively high increases of course only result in moderately higher amounts in euros, which also apply to a whole year Respectively. The vehicle tax for the VW Up GTI will rise by 72 percent,but that's just 36 euros, i.e. 3 euros per month.

And here is the table for which the ADAC has already calculated the increase in vehicle tax:

For all models the ADAC was able to take both the CO2 value according to WLTP (in the vehicle license: field V.7) and the CO2 value according to NEDC (field 22) specifically from the respective registration certificate Part I and thus calculate the vehicle tax.

According to ADAC, “warehouse vehicles (end-of-series) that have been type-approved according to the NEDC. For the 'the manufacturer can apply for an exemption from the Kraftfahrt-Bundesamt (KBA). If this is approved, the CO2 value according to the NEDC will continue to be used for tax assessment. How many manufacturers will make use of this exemption is not yet foreseeable ', according to the automobile club.

And what about the Emissions standards?

From September 1, 2018, new emissions standards will also apply, the introduction of which is intended to significantly improve the air in cities after the diesel scandal - because they are measured according to RDE (Real Driving Emissions), i.e. below Real conditions on the road with mobile measuring devices (PEMS). Only cars with emission standard Euro 6c with OBD standard 6-2 (emission key number in the registration papers: 36AD), ​​Euro 6d-TEMP (36 AG), Euro 6d-TEMP-EVAP (36BG) and Euro 6d (36AJ) are then only eligible. .

The biggest difference between Euro 6c (with OBD norm 6-2) and Euro 6d-TEMP is that with Euro 6d-TEMP the RDE conformity factor (CF, Conformity Factor) for nitrogen oxide emissions NOX of 2 , 1 must be achieved (Euro 6d-TEMP-EVAP only stands for a revised test method for evaporative emissions). For Euro 6d the RDE conformity factor then drops to 1.5. The original Euro 6 limit value of 80 mg /km (diesel) can be multiplied by this factor - for Euro 6d Temp it is 168 mg /km, for 6d it is 120 mg /km.

The authorities introduced the conformity factor to give car manufacturers time for further technical developments. Because the original limit values ​​are much more difficult to meet with the considerably more demanding RDE tests - in reality the new emission standards are cleaner than the previously uncorrected ones despite corrected (higher) limit values.
