The 2023 Formula 1 season springs into life this weekend at the Bahrain Grand Prix, the first race of the year. Three days of preseason testing held last week suggest that Red Bull Racing still has the car to beat, although there is the tantalizing prospect of Fernando Alonso and Aston Martin having possibly found a lot of speed in the offseason.

But today's interesting news comes from the lower formulae, F2 and F3, where young drivers cut their teeth. Today, those series announced they are moving to sustainable fuels starting this season.

As we've previously detailed, F1 is moving to carbon-neutral gasoline in 2026, but as single-make formulae with a single fuel supplier (in this case, Aramco), it's possible for F2 and F3 to try something even bolder.
