Winning at the slowest possible speed is an old racing philosophy espoused to great effect by Alain Prost in his Formula 1-conquering days, so there's some irony in how last season he watched a Formula E rival put it into practice.

The Renault Z.E.15 was the pick of the powertrains in the first season of open motor/gearbox/inverter competition, and the evolutionary Z.E.16 kept the Prost/Jean-Paul Driot-run Renault e.dams team atop the pack in performance terms. But Lucas di Grassi and Abt Audi Sport, with a sprinkling more Audi assistance than before, managed to steal the title at the final round... despite being slower throughout most of the season.
