We argue that this perspective is driven by normative ideas and rhetoric and that it is more likely that a very limited set of rather similar technologies will survive as successors to the fossil fuel powered internal combustion engine. Economies of scale of core components and the necessary build-up of infrastructures will eventually give these a decisive lead over its competitors. Our perspective has two implications. First, the cars of the future are and will be competitors and hence there will be winners and losers. Second, policy should be targeted at the set of technologies that are most desirable from a societal and environmental perspective, rather than at the wide variety that is being developed today. Given the challenges of climate change and local air pollution, the electrification of the powertrain should be prioritized at the expense of alternative fuels such as natural gas and biofuels","cars of the future, dominant design, innovation","en","conference paper","World Electric Vehicle Association","","","","","","","","OTB Research Institute for the Built Environment","OTB Research","","","",""
