Backs up Lewis saying the sim lead him down the wrong path in the past and why hes stopped using it. Big package at Zandvoort

"No simulator manages to perfectly predict the behavior of these electric F1 cars
One of the most interesting aspects concerns the simulators. At Maranello, simulations indicated a Ferrari as much as 6-7 tenths slower on some circuits, and this applies to Spa as well. Relatively similar assessments came from the tools used by the competition too. The problem is that no one is coming even remotely close to the usual level of precision. Today's F1 cars have extremely high sensitivity. The algorithm adjusts performance based on the aerodynamic load actually produced on track, but variations in grip change how that translates into traction. Traction then affects how electrical energy is deployed. At that point the simulation loses precision. It's a chain of events that no model today can yet reproduce perfectly. For engineers, lap time has become a balance between three factors: aerodynamics, traction, and electrical deployment. Each one weighs almost as much as the others. If one of the three elements falls outside the ideal window, overall performance drops quickly and the setup goes haywire. Ferrari is the team that has modified the car the most in recent weeks. The first jump came with the Barcelona aerodynamic package. In Austria, the first evolution of the ADUO power unit was introduced. The use of a new Mgu-k specification also went almost unnoticed, brought into the pool together with the update to the internal combustion engine and the turbocharger."
Developments don't stop, more news after the summer.
Work continues under the guidance of technical director Loic Serra, while at Silverstone the head of aerodynamics Diego Tondi was also present in the garage — a sign that aerodynamic development of the SF-26 remains an absolute priority. The third major performance package is expected after the summer break, with its debut planned for Zandvoort. It will include performance components and some specifications dedicated to the high-load circuit.
Mercedes more cautious on upgrades. Mercedes, on the other hand, has chosen a more conservative strategy. The advantage accumulated in the first part of the season has allowed it to proceed with less aggressive upgrades, without upsetting the balance of the W17. After the FIA's intervention on diffuser restrictions, some specifications planned for that area were shelved. This could have appeared to be a disadvantage or a setback, however Ferrari too had given up on some rather complex parts that could have had consequences."
Filming day for Ferrari at the new Madrid street circuit
https://autoracer.it/filming-day-9-lugl ... ringrazia/
The circuit's inauguration took place just a few days ago, with Carlos Sainz in attendance along with the main political authorities who contributed to building the facility and the Grand Prix that will be held in September. A few laps have already been driven, but no 2026 Formula 1 car has taken to the track yet. It will be Ferrari that gives the new Spanish circuit its baptism of fire. Charles Leclerc and Lewis Hamilton will indeed hit the track on Thursday with the SF-26 to make use of the second available filming day: 200 km in total for the two Ferrari drivers. Ferrari is therefore getting ahead of the game, but above all is seizing an opportunity served up on a silver platter. According to what AutoRacer has learned, it was in fact the Madring organizers who invited the team to the circuit for a promotional event, entrusting Ferrari with the task of "inaugurating" the track with a Formula 1 car and covering all the event's costs themselves.
Ferrari has agreed, but has also gone a step further. It will not show up on track with a historic car, a GT, or an old Formula 1 car usable for TPC testing; instead, it will bring the SF-26 directly to Madrid, taking advantage of the second of the two available filming days. There will be no new components to test or anything else—the SF-26 will essentially be the same as in the last few races. This way, it will be able to gather valuable data ahead of the September Grand Prix, while at the same time achieving significant financial savings thanks to the organizers covering the costs. It may seem like a marginal detail, but in the Budget Cap era, saving a few hundred thousand euros on logistics costs—transport, circuit rental, session fees—is anything but irrelevant, especially if the season continues to be marked by a tight battle on the development front, an aspect Toto Wolff has been drawing attention to for some time now. Ferrari, however, just as with the development of the SF-26, wants to push right up to the limit allowed by the regulations: this too is an opportunity seized in a more aggressive, shrewd, and efficient manner.
