While traditional Formula 1 is confined to dedicated race tracks, Formula E takes over the streets of cities across the globe. And instead of the noise and fumes from diesel-powered machines, Formula E cars are powered by electricity and speed through city streets with low-level noise. Which isn’t to say that they’re not fast. Rapid evolutions in the tech that powers these beasts mean that Gen2 cars can now hit 280 km/h. And these innovations are starting to be used in road-ready vehicles too. With road transport accounting for a big chunk of global greenhouse gas emissions, could Formula E shake up the future of transport and pave the way for greener streets?
