On March 7th, 2019 the IMS Colloquium E-Mobility 2019 took place at the August-Euler-Flugplatz of the TU Darmstadt. More than 30 drive experts from the automotive industry and research followed the invitation of the Institute for Mechatronic Systems (IMS). In addition to three technical presentations on selected results of the DE-REX project, the participants were able to gain an impression of driving and gear shifting comfort in electric and hybrid operating modes during a driving test in the DE-REX prototype vehicle.
