The Scania OmniLink is an integrally-constructed rear longitudinal-engined citybus available on the European market. It is a complete product built by Scania AB, a company based in Sweden. The OmniLink was launched in 1998 with an inclined engine and was designated CL94UB, and an articulated version was designated CL94UA. But when the Euro IV version was introduced in 2006, the engine was no longer tilted and the designation changed to CK230UB/CK270UB/CK310UB for the rigid version.
