Integration of economic and ecological considerations with engineering ones in new vehicle concepts presents many challenges, not least of which is overcoming long established expectations of vehicles and their performance. Design choices are not only influenced by clear rational factors but also by many imperfectly rational ones, which interact in a complex way to shape the final vehicle artefact. It should therefore be of interest to model and explore how such factors interact and influence the design process, particularly when it comes to targeting limited resources towards achieving the maximum improvement in the design. The aim is to find out under what circumstances can specific improvements penetrate into the established vehicle design and where are the critical phase boundaries over which significant advancement may be achieved. This is especially relevant in light of the on-going adoption of new technologies aimed at reducing the environmental impacts of vehicles. This insight may enable the design and adoption of radically different vehicles that represent a tipping point for sustainable transportation. A methodology is introduced to dynamically explore the trade-offs in vehicle design. The engineered vehicle is recognised as being a sub-system within a much wider surrounding world. A broad model is introduced to include both rational performance properties and imperfectly rational forces, and the system is stepped forward in time. The methodology is applied to a case study in which new knowledge is introduced into the established design paradigm and its adoption is tracked under a number of starting conditions and assumptions. The results illustrate where a targeted improvement that compensates for inherent inertia may lead to greater adoption that is beneficial from a broader long-term perspective. The model behaves reasonably in the vicinity of boundary conditions but more work is needed to explore and refine the behaviour across multiple variables.
