Abstract Over next decade, SI engines might adopt a significant amount of design solutions from CI engines. Therefore none of both can be finally called the winner – they are merging into an optimized engine for future sustainability requirements and heavily depend on technology readiness and technology cost, customer acceptance as well as total cost of ownership assessments. The fuel of choice (e.g. E-methane and E-DME) might determine which engine type can deliver lowest CO2 emissions. To enable deep CO2 emission reduction by e-fuel deployment in the long run, CO2 should be extracted from the atmosphere to enable a closed-loop carbon cycle. In the mid-term and due to cost-benefits for CO2 provision, the utilization of CO2 from unavoidable sources based like steel works might be an option. All presented options to further reduce CO2 emissions require additional efforts towards the implementation into the vehicle fleet and fuel supply infrastructure.
