[4] In July 2008 the Solaris Bus & Coach company signed the largest order yet in its history with the Athens company ETHEL (OSY as of July 2011) for the delivery of 320 buses, including 220 Solaris Alpino with engines of Euro 4 standard.

The first customer, who contributed to the creation of the model, placed an order for three types of the low-entry bus, to a company in Austria.

The first information about it appeared during the AUTOTEC Trade Fair in Brno in June 2008, after the delivery of the buses to Austria.

It is equipped with Cummins ISBe4 250B engine (with a capacity of 6.7 dm3 and 250 HP in power) centrally mounted at the back and a Voith DIWA 854.5 automatic gearbox.

The front suspension can be installed independently or alternatively with the IFS Voith ZF RL 75 EC.

By using these solutions such as the central lubrication system and the self-diagnostic KFBS1 Kogel and the maintenance-free bearings in the drive and steering, this has reduced servicing time and cost.
