This study focuses on future powertrain systems with the aim of defining the most probable implantation road map for the different alternatives to improve powertrain efficiency. A new methodology called Technology Development Envelope (TDE) for transforming the roadmapping approach to the level in which it is dynamic, flexible and operationalizable is applied for a case study of Ford Otosan's technological planning concept. In the first section, technologic roadmapping methodology is explained. As a next step, each powertrain solution is defined. Advantages regarding efficiency, fuel consumption, cost effectiveness, emissions, infrastructure and performance have been listed. In the next sections, TDE methodology and a pre list of technologies are explained in detail. A series of criteria and sub-factors have been defined with the aim to compare the different powertrain systems to identify the best solutions.
