New for the 2022 season, all 10 F1 teams have to declare any new upgrades they introduce ahead of Friday practice for each grand prix weekend.

A mandatory car presentation takes place in the pit lane on Friday with all teams required to present their cars and explain any new parts they have brought to the event.

In a bid to turn their season around, Mercedes have brought new upgrades to Miami. 

Will Mercedes' F1 struggles continue?

Mercedes struggled last time out at the Emilia Romagna Grand Prix, although George Russell managed to salvage fourth after making a storming start.

Seven-time F1 champion Lewis Hamilton struggled to 13th after being stuck behind AlphaTauri’s Pierre Gasly for much of the race at Imola.

Mercedes have introduced a new rear wing as well as a beam wing while making changes to the W13’s front wing endplate.

It wants to reduce the drag levels the W13 is currently producing with low downforce and straight-line speed crucial around this new Miami circuit.

Speaking ahead of Friday practice, Hamilton doubted the impact Mercedes’ upgrades may have on their outright performance.

“You can expect that we will be giving it our all,” he said. “We’ve been trying our best and there’s been a huge amount of work in the background. You can see we’ve got a new rear wing for example, so I’m just grateful for everyone keeping their heads down and for the amazing hard work that everyone is putting in.

“I don’t anticipate much change in that sense.”

On the other hand, Red Bull haven't brought any new parts to Miami while Ferrari have only introduced a new rear wing specifically for Miami.

Here is a full rundown of what each team has brought to the Miami Grand Prix.

Mercedes

A new front wing endplate to improve the efficiency of the component. New rear and beam wings to reduce drag as part of a lower drag aero package for this weekend.

McLaren

McLaren have made changes to their front suspension to ‘improve tether and brake line packaging around the lower wishbone’. They have also updated the floor edge to allow for a better understanding of the porpoising effect.

Alpine

Alpine have updated the rear corner of their car as it looks to bring more rear downforce and better airflow.

Williams

A change to the cooling louvres to allow for better cooling given the high temperatures expected this weekend in Miami.

Like Williams, Alfa Romeo have made changes to their cooling louvres with high temperatures predicted.

Haas

The American outfit will run a circuit-specific rear wing to reduce drag and thus perform better on Miami’s long straights.
