Automakers are embracing with vigor the strategy of dedicated platform sharing, which portions common design, engineering, and production efforts over a number of outwardly distinct models. Platform sharing mixes lower-volume “differentiating” technologies to increase market attractiveness with higher-volume “standardized” technologies to lower overall costs. Disruptive advanced technologies like polymer composites and the Hypercar concept, ill-suited to conventional, mass-production automaking, may fit very well within the new rules of platforms.
