Technical updates: 2025 Miami Grand Prix

Red Bull has a new floor development amid limited upgrades for the Sprint weekend at the Miami Grand Prix. The race schedule has teams facing just one free practice session in Miami before Sprint qualifying on Friday afternoon, but despite that McLaren took a big step forward with a major upgrade at this event a year ago. On that occasion the Red Bull was the dominant car but looking to close the gap to McLaren this time around, repositioned floor fences and additional camber on the floor edge are designed to increase overall load and improve balance. “It’s reasonably stable,” Red Bull chief engineer Paul Monaghan said. “We can bring it at relatively low risk because it’s a Sprint race. It’s an opportunity to do it, we were able to do it. People worked really hard in the factory to put it on the car so we can enjoy the benefits. “In our judgment, the flow stability remains unchanged. So we are not fearing it to be aerodynamically unstable or anything of that nature. It can go on and it will give us a few kilos of load and we will enjoy the benefit. “It’s one of , yes. If you think of all the complaints we had out of Bahrain, we’ve addressed some. Have we done it wholly? Probably not? Will we continue? Yes. It won’t be a sort of turn-key solution to unlock. It will be more incremental improvements on the car. “We understand what’s happened but actually affecting a cure, it’s not that straightforward. It may never disappear from the car. Can we reduce the magnitude and improve the lap time? Yes. There’s a lot of incredible people at Milton Keynes working hard to improve and it will come.” Aside from Red Bull, Mercedes has reduced the camber on its rear wing flap for the Miami circuit, while Aston Martin has made similar circuit-specific tweaks to the front wing, rear wing and beam wing. Williams makes slight changes to its beam wing with a lower downforce and lower drag option, and Alpine has a new front brake duct and front suspension that work in tandem to improve both airflow and cooling efficiency. Sauber also has updated its front suspension to similarly improve airflow to the rest of the car.
