In addition to the basic model, which is powered by a diesel engine which meets the Euro V emission standard, there are versions produced to meet the EEV and fueled with CNG or the second generation hybrid bus model.

5 September of the same year, the first low-floor buses Neoplan N4020 (15 metre long) were ordered by Warsaw.

[9] Initially, the 18-metre buses did not sell well because the transportation companies preferred smaller and cheaper 15-metre vehicles.

[11] In total, cities in Poland bought 12 units of the Solaris Urbino 18 First Generation.

Articulated vehicles were mainly built for export, most Solaris Urbino 18 were bought by a company from Berlin and Riga.

[13] A major order by MZA Warsaw in 2005, resulted in the significant increase of the sale of the Solaris Urbino 18 in Poland.

In December 2006, Olsztyn was the first Polish city to receive 8 units of the Solaris Urbino 18 model which meets the Euro V qualification, which came as standard for new vehicles in 2009.

[15] The first Solaris Urbino 18 CNG went to Lublin in November 2006, in October 2009 another was sold to Radom in Poland.

[22] The new buses are more durable, lighter and more refined in terms of design and construction when compared to the previous generation models.
