"When have we seen, in the history of racing, Mercedes against Audi against BMW against Porsche? I don't know if we ever have, but that sounds pretty damn exciting. That's going to get massively good to watch."
This is Nico Rosberg getting ever-so-slightly excited at the prospect of the four titans of German automotive manufacture going head to head (to head to head) in Formula E within the next 18 months. As well he might, for in an improbably short space of time, the all-electric race series has gone from being an intriguing technical curio to a racing and tech-innovation showcase that carmakers simply can't ignore.
Manufacturer interest in the series was apparent from the beginning, as Renault's e.dams squad emerged comfortable season-one champion, but even the most optimistic daydreams of CEO Alejandro Agag would surely never have forecast ranks of blue-chip brands queueing up to join.
