the year 2030 , linking up more cities and regions with one another .
The innovative engineering is based on lightweight trailer bogies with inner bearings , SIBAS PN electronic vehicle steering and a modular drive system consisting of independent powercars with identical traction technology . This method , a joint development by Siemens and Bombardier , enables flexible configuration of the ICE 4 to meet different traffic requirements . The 12-part train is driven by six powercars .
Despite its high seating capacity for
830 passengers , the 12-part train is comparatively lightweight . Compared with an ICE 1 with 12 trailer coaches , the ICE 4 has an unladen weight of 670 tons , roughly 120 tons lighter than its predecessor . This reduction in weight has been achieved by using a new type of trailing bogie with inner bearings , which is significantly lighter than the previous bogies . Moreover , the unpowered end cars can be fitted with aerodynamic shrouds . This means that energy consumption per passenger seat is up to 22 percent lower than that of a modernised ICE 1 .
