In June 2012, as part of tests, the first prototype bus carried passengers free of charge for three weeks during the UEFA European Football Championship 2012, in Poznań on the “E” line, running from the International Airport Poznań – Ławica, past roundabout Rondo Kaponiera up to shopping, art and business centre Centrum Handlu, Sztuki i Biznesu Stary Browar. During that time the bus covered about 3000 km failure-free. For promotional purposes the bus body was covered in artificial grass, while the headliner featured the image of the sky. In July 2012 the bus was tested by operator MZA Warszawa on the bus line 222 (which later was serviced by Solaris Urbino 12 electric buses acquired by the operator in 2015) . In the same year, the bus was also tested on the 370 bus line route on the streets of Jaworzno. During tests in Zakopane, the Urbino electric 8,9 LE carried passengers among others to mountain lake Morskie Oko.
