Not bad, but it's still very early beta, I even think this is an alpha version. I hope that this Ikarbus will be finished, especially because I like one of its' predecessors, Ikarus-Zemun IK160, the articulated mid-floor bus from 1980s* with great sound and cool look, and I find the IK103 (and its' relatives) a very good successor of the IK110/160 series.
*- In Poland they were in service from 1982, about 10 to 12 buses are in service till today in PKS Ostrów Wielkopolski, three of the out-of-service ones (from various PKS firms) are set as historical buses and one is being renovated in Warsaw, the other two are standing in Paterek near to Bygdoszcz and are waiting for their time
IK160B has got Raba-MAN D2156 HM 6U engine and FAMOS 6MS 80.56 gearbox produced by FAMOS as the licensed version of ZF S6-90U, IK161R probably Raba-MAN D2356(?) engine and also the manual FAMOS gearbox. IK166 has got MAN D2866UH engine and Voith D851.2 automatic gearbox. The weirdest version is the IK170- a trolleybus.
Photos of each version you can find on phototrans.eu or simply by searching them in Google.
I hope you won't warn/ban me for so long annotation
