The necessary quantity of AdBlue® depends on European environmental legislation which will most probably evolve. Manufacturers have to adapt to the consumption of AdBlue® in order to respond to changes in environmental standards.
Tanks of diesel cars meet the requirements of the current anti-pollution standards. However, the European Euro VI regulation will most probably change with the entry into force of the Euro VIb standard by at the latest 2019. Diesel cars will have to consume more AdBlue® to meet the higher requirements for reduced emissions of nitrogen oxides. Although the size of the tanks is to evolve, the owners of future models of diesel cars will consume two to three times more AdBlue® to clean up and will have to fill up more frequently.
