The Ferrari Formula 1 team has given a statement of intent with confirmation from the FIA of the scale of its Miami Grand Prix package with 11 declared updates.

The official presentation submissions document issued at each race details changes by areas of the car.

The total number of updates doesn’t necessarily provide an accurate reflection of the scale of a package, as for example a new rear wing or floor carries the same weight as a minor mirror fairing tweak.

In addition McLaren is known to have more parts coming for Montreal, and others may also have split their post-break updates across two races.

However the total does give an approximate idea of how much work a team has done, and Ferrari’s total of 11 is one of the highest seen at a single race since the update declaration system began.

In contrast McLaren, Williams and Cadillac have declared seven updates apiece, Racing Bulls and Alpine six, Mercedes and Audi two, and Haas one. Aston Martin has no updates at all.

Ferrari’s list includes a new floor, floor edge, diffuser, rear wing, beam wing, front and rear endplates and front and rear suspension fairings.

Regarding the work at the front the team says that the “front wing endplate and front corner updates are working hand-in-hand, focusing on flow feature stability and front wheel wake management throughout the entire car operating envelope.”

Ferrari adds that “working together with the front floor update, the rear part of the floor and diffuser have been developed focusing on load increase across the full operating window.

“In addition, the rear trackrod fairing update together with the rear tail devices provides a favourable pressure gradient for the diffuser, in an efficient manner.

“Benefiting from enhanced upstream flow conditions, the front floor geometry and devices have been re-optimised, returning a net load advantage.”

At least some of the Miami package was trialled at the Monza filming day during the break, although on Thursday both drivers were keen to downplay the running.

However when asked by Crash.net how productive the break was Lewis Hamilton confirmed that it had been valuable both for the team and for him personally.

“I think it's been good for everyone to step back and have a look at analyse the first three races,” he said. “And obviously the last race, I felt I was I could see I was down on power.

“We did a deep dive and understand that it wasn't the engine, but the systems all together, including several things coming together to lose me over the eight to nine tenths, which is some straightline power. So we got on top of that.

“I worked in the sim, been in the factory every week, training a huge amount, and I feel refreshed heading into the weekend."
