The Siemens Inspiro is an electric multiple unit designed and manufactured by Siemens Transportation Systems since 2012 for metro systems. The product was launched on 19 September 2012 at the InnoTrans in Berlin. The first Inspiro entered service with Warsaw Metro on 6 October 2013.


In October 2009, Siemens Mobility started development on a new subway product family. It collaborated with DesignworksUSA on design aspects.[1] The company based its design on Mo.Mo vehicles previously produced for Vienna, Prague, Oslo and Nuremberg.
