KOMEL and SKB Drive. Later on companies El-Cab and ENEA joined the cluster. In 2018 Solaris announced the debut of the three following vehicles: the Solaris Trollino 24, the Solaris Urbino 12 hydrogen with a hydrogen drive and the Solaris Urbino 12 LE lite hybrid, meaning a low-entry and low-emission bus involving lower operating costs. Coaches In the first years of operation, Neoplan Polska also handled the assembly of the coaches Neoplan Transliner and Neoplan Skyliner. Serial production of the tourist coach of the company's own design Solaris Vacanza 12 began one year after the official unveiling in August 2001. The design of these coaches was drafted by the Berlin-based enterprise IFS Designatelier. A characteristic feature of these vehicles is the wedge-shaped bodywork line. Engines made by DAF were used for the driveline. In 2004, the company launched production of the longer model Solaris Vacanza 13. In 2003 the Solaris Vacanza was ranked second (ex aequo with the Volvo 9700) in the contest Coach of the Year 2004, right behind such brands as MAN Lion's Star and Scania Irizar PB, which took the first place ex aequo. Due to limited sales, Solaris decided to eliminate them from its offer in 2011. In 2002 Solaris assembled its first special purpose vehicle - a mobile blood donation station based on the Vacanza coach. Solaris bloodmobiles have been used in many Polish cities, but have also been sold to Riga. In 2018, Solaris presented the first fully electric special vehicle for blood donation, based on the Urbino 8.9 LE model. Trolleybuses Solaris Trollino trolleybuses have been produced since 2001, based on low-floor buses of the Solaris Urbino series. The first Trollino 12 units were created in collaboration with PKT Gdynia. In 2002, the company launched serial production of longer trolleybuses, namely 15-metre and 18-metre versions. The Solaris Trollino 15 was the first trolleybus in the world of that length. Originally, the vehicles were made with drives manufactured by Hungarian company Ganz Transelektro and Czech firm Cegelec. In spring 2007, Solaris and the firm Medcom from Warsaw decided to build a prototype of the trolleybus Solaris Trollino 12, fitted with an asynchronous drive made in Poland. It was created in August 2007 and was then submitted for tests in Lublin. Two more vehicles were made for public operator MPK Lublin. Tychy-based TLT, too, is authorised to assemble and obtain the type approval for the
