MAN Lion's City is a city bus built by the German truck and bus manufacturer MAN Nutzfahrzeuge since 2000. A new generation was launched in 2004. It has a 6-cylinder turbocharged straight engine which runs on diesel, compressed natural gas or liquefied petroleum gas. Versions with hydrogen fuel cell drive and with hydrogen internal combustion engines have been successfully tested, as well as diesel-electric hybrid drive, and the latter is due to enter serial production in 2010. The latest generation of Neoplan Centroliner is based on the Lion's City (Neoplan is a part of the NEOMAN group).
