A completely new development compared to the → predecessor series ICE 1 and ICE 2 was the ICE 3, which has been in use since 2000 and no longer had powerheads. Instead, there are traction motors mounted under the coaches. The ICE 3 series 407, which have been in use since 2014 and are labelled as "Velaro D" by the manufacturer, are mainly characterized by a significantly modified front.
The ICE 4 is in service since 2017, which is another completely new development to replace the ICE 1 and 2 in the medium term.
