Even in its mid-2000s car-manufacturer pomp, Formula 1 has had nothing compared to what Formula E is enjoying now. Its nine-strong manufacturer entry already has impressive names - Renault, Audi, BMW, Jaguar and DS join a quartet of electric-vehicle specialist/emerging brands at present.
You are unlikely to have missed the news that Mercedes is axing its DTM programme to join Formula E in 2019. Porsche will quit the LMP1 division of the World Endurance Championship at the end of this season to do the same.
Then there's the prospect of a Fiat-Chrysler entry, although that's more likely to be with a brand like Maserati than Ferrari. All that's missing is a Japanese manufacturer, although Honda has sniffed around in the past and Nissan could be on its way into the series as a replacement for alliance partner Renault.
