Since transportation is one of the main contributors to carbon emissions and one of the biggest consumers of oil, new technologies to propel vehicles are being introduced. For the automotive industry, where the Internal Combustion Engine (ICE) has had complete dominance for some hundred years, the transition to new powertrains will be challenging for the entire operation. These new powertrain vehicles must not only be developed and tested, which is an enormous challenge in itself; they must also be manufactured with the same efficiency as ICE vehicles in order to reach a competitive price. There is great uncertainty regarding which powertrain solution will become the next paradigm, or even if there will be a new propulsion paradigm as dominant as the ICE. This, in combination with the fact that these new powertrain vehicles will initially be produced in relatively small volumes, probably calls for them to be produced in current manufacturing facilities mixed with ICE vehicles. This challenge is the foundation for this research.
