When developing a new electric powertrain for Formula E, multiple objectives must be balanced and prioritised. Power, efficiency and controllability are all crucial for manufacturers, and compromise is inevitable when determining the best overall package. A highly efficient powertrain is of little use if it cannot reach maximum power quickly enough, has too much inertia, or lacks the necessary software controls for energy management.
Each of these core elements also involves additional considerations, highlighting the extensive work required to bring a project from concept to the track. Since Formula E began a decade ago, and powertrain development was opened up in season two, several aspects of the design and development process have matured hugely. We now have more knowledge and better tools than we did back then.
