BNOx Presskit

With the BNOx system, the Baumot Group offers a retrofit solution that lowers nitrogen oxides by more than 90% under real conditions (RDE). The emission values it achieves under real conditions in retrofitted vehicles of pollution class EURO 4 and higher are better than those of the current EURO 6 category. In future, this would enable you to qualify your vehicle for the blue sticker and gain access to "blue zones".

Blue sticker

As with the existing green sticker for EURO 4 vehicles, only vehicles that satisfy the EURO 6 standard will obtain the blue sticker. Older vehicles with the blue sticker will still be able to enter designated blue zones in cities and municipalities if they are upgraded to the EURO 6 values with a retrofit solution such as the BNOx system. The introduction of blue stickers and their requirements are currently under discussion at the federal level in Germany. If the blue sticker is introduced, it would offer owners of older model vehicles a way to minimise their loss in value and to maintain their mobility while preserving the environment at the same time.
