Pat Symonds, F1’s chief technical officer, says plans are on the table to introduce active aero to the cars in 2025 to reduce fuel consumption.
In 2019, Formula 1 announced it would become net-zero carbon emissions by 2030. Pat Symonds said that the active aero would help achieve that goal as F1 cars would then need about 25% less fuel than they were currently using. Another option on the table was using synthetic fuels that would deliver more power per kilogram over the current fuel.
“We’re fighting for mass in Formula 1. The cars are very, very heavy. You could say, in a qualifying lap, does it matter you’re carrying 2kg of fuel instead of 7.5kg of fuel? It’s not the end of the world. But if you’re starting a race with 100kg of fuel because your energy density is only half, then you’ve still got a heavy car. So I think it does matter,” Symonds told RaceFans.
Symonds wanted current levels of car performance while making the sport more sustainable. He believed enhancing technology via using active aerodynamics would help in that regard.
He said on that subject: “You don’t have to be an engineer to realize that one of the reasons we use quite a lot of fuel on these cars is because they’re high-drag, so the first thing you’ve got to do – apart from the fact you’re moving into much more hybridization, a lot more like electrification on the car – you’ve got to get some drag out of it. So there will certainly be some drag reduction. But with that drag reduction comes a downforce reduction so then you can’t go around the corners so fast. So that leads you to say that you’ve really got to have active aerodynamics on the car.”
