Ferrari brings major F1 floor upgrade to United States Grand Prix

Although the team and Sebastian Vettel need some good fortune to stop Lewis Hamilton and Mercedes clinching the crown, the team is not slowing down with its development push.

Upgrades to the SF71H for Austin are focused on the floor and bargeboard area, with a host of aero tweaks the team hopes will deliver it a much-needed performance boost.

In front of the rear tyres, Ferrari has introduced two banks of extra fins above the side-channels.

While the design will help better manage airflow around the rear tyres, in what is a tricky area of the car, one of the other aims of the fins could be to divert rubber debris.

In Japan, during trials of a new floor there, tyre debris was seen to have blocked up a slot Ferrari had introduced at the back edge of the floor - negating any theoretical aero advantage from the new design.

Ensuring that such debris is kept away from this slot should ensure it performs more consistently and produce the results the team has seen in the windtunnel.

At the back of the floor, Ferrari has extended the area around the edge of the diffuser - adopting a similar style to Red Bull.

Ferrari has also made changes to the complexity of its bargeboard area as well (below), with a host of new fins along the leading edge.

Speaking ahead of the Austin weekend, Vettel was clear that Ferrari needed an uplift in pace if it was to have any hope of taking the fight to Mercedes.

"It's pretty clear, we need to be quick enough to win the races and then it depends on what the others are doing," he said.

"Obviously we were missing something in the last couple of races, we clearly didn't have the speed to be up there.

"We need to make sure that the next couple of races show us the direction and we get the results I think we deserve."
