Formula E's script has not been torn up, but its main character has been rapidly rewritten.

Lucas di Grassi was penned as the title favourite, but the Audi Sport Abt driver's championship challenge has not so much stalled as failed to start completely. Conversely, Felix Rosenqvist has quietly assumed the leading role, with two wins from three races.

Audi's testing performance convinced many, including this writer, that it was indisputably top dog.
