Competition was no less intense than it is today, but focused on economic performance, with design driven by costs and the use of existing manufacturing capacities.

Innovation, while not absent, has nevertheless been restricted in such a context. However, changes in regulations and customer demand have led to an evolution in transmission specifications,...
