I’m pretty sure that — despite the public disliking the new V6 engines and their sound — Formula 1 will go all-electric within the decade. Maybe at first there will be only an electric final drive, with a combustion engine on board that generates the electricity (like the Opel Ampera), but there’s just no stopping electric engines. That’s where the world is going and manufacturers will not want to develop their petrol engines, just for the sake of Formula 1.
I for one think it’s an exciting development. Formula 1 has always been at the forefront of technology and can’t afford to stay stuck in a foregone era of fossil fuels.
