The work gives the team a more informed starting point—not a guaranteed prediction of how the real car will behave. Track data and driver feedback are still needed to test and refine what the simulator suggests.
What an F1 driver-in-the-loop simulator is
A driver-in-the-loop, or DiL, simulator is an interactive environment in which a driver controls a virtual car while engineers can use the session to examine circuit, car and setup questions. It serves two connected purposes: the driver can practise a lap and build familiarity, while the team can investigate possible approaches before spending limited track time on them. Formula 1’s 2023 explainer of F1 simulators describes both driver preparation and engineering work such as examining parts and car setups.

The important distinction is that a simulator session is not simply a virtual copy of a Grand Prix. It is a way to ask questions and narrow choices under modeled conditions. The answers are useful only to the extent that the virtual car and circuit behave closely enough to the real ones for the question being considered.
Driver-in-the-loop simulation is not CFD
Computational fluid dynamics (CFD) is a separate engineering tool. It calculates the behavior of fluid flow—in this context, gaseous flow around a car—rather than putting a driver in control of a virtual lap. The FIA’s 2026 Operational Regulations, Section F, issue dated 28 April 2026, define restricted CFD simulations and include preprocessing, solver and postprocessing within that framework. That regulatory definition should not be confused with the interactive driving and setup work of a DiL simulator.

What teams prepare for before the cars reach the circuit
Learning the layout and building a driving plan
A driver can use virtual laps to become familiar with the sequence of corners and the demands of a circuit before driving there in an F1 car. That is particularly useful when the venue is new to the championship: the driver may have no previous F1 race weekend at that track on which to draw. Simulator work can help turn a first real outing into a process of checking and refining an initial understanding rather than encountering every feature from scratch.
Formula 1’s report on preparation for the new Madring, published on 11 September 2026, said drivers had completed “thousands of laps” in team simulators before the venue’s first race weekend. The article also reported that only two current drivers had sampled the venue beforehand at a brief filming day. “Thousands” is a broad report, not an exact count per driver or a measured statistic with a stated method. It should not be read as a standard workload for every circuit or team.

Drivers can also explore where the limits of a modeled circuit and car may lie. That does not make a virtual lap equivalent to a real one: the session is preparation, while the first on-track laps reveal how the real venue and car respond. The simulator is most useful when it gives the driver a set of informed expectations to test, not when it is treated as a substitute for track experience.

Giving engineers a head start on setup questions
Setup means the adjustments made to configure a car for a particular circuit and its conditions; Formula 1’s F1 glossary entry on setup provides the sport’s terminology. Engineers can use simulator sessions to examine setup options and parts before the team has real track running from that weekend. The aim is not to settle every choice in advance. It is to investigate plausible directions and arrive with a better-informed starting point.
That distinction matters because a setup decision depends on how the modeled car behaves relative to the real car. If the two do not correlate well for a particular behavior or condition, a convincing virtual result may not produce the same outcome on the circuit. Formula 1’s explainer explicitly frames simulator usefulness around the correlation between virtual and real worlds.
Preparing for operational demands
Preparation can also include practice for operational tasks around running the car, rather than only learning a corner or considering setup. The exact tasks and session plans vary by team; public sources do not establish a single checklist or timetable that every team follows. The practical value is that a driver and engineers can use a controlled session to think through the demands expected at a venue before those decisions have to be made during a live race weekend.
How the simulator work connects to a race weekend
There is no public basis for claiming that every team follows one identical sequence or spends a fixed number of days in the simulator. A useful way to understand the process is as an iterative chain of questions, virtual investigation and real-world checks. The detail varies, but the underlying logic is preparation followed by validation.

- Start with the circuit and the questions. The team considers what it needs to understand: for example, how the driver will approach an unfamiliar layout or which setup directions merit attention. A new venue makes this stage especially important because there is no history of prior F1 race running at that circuit to consult.
- Explore in the modeled environment. The driver can build circuit familiarity, while engineers can use sessions to examine parts and setup options. These are connected uses of the simulator, but they are not identical tasks: the driver is developing a feel for the virtual lap, and engineers are investigating choices about the car.
- Carry an informed starting point to the circuit. The team uses what it has learned to guide its early thinking, not to assume that virtual conclusions are final. The simulator cannot eliminate the need to see how the car behaves in the actual conditions of the weekend.
- Compare assumptions with track running. Engineers analyse track data and drivers report what they feel in the real car. If those observations differ from the simulator’s expectations, the team has reason to revisit its understanding and make further setup adjustments.
- Refine as evidence arrives. Each real-world check can improve the next decision. Simulation narrows the field of questions; circuit running determines whether the assumptions behind those decisions hold up.
This is an explanation of the feedback loop described in public accounts, not a claim about the order, software, schedules or procedures of a particular team. Formula 1’s simulator explainer and its glossary entry on setup support the broad relationship between setup work, simulator analysis and adjustments at the circuit.
Why a new circuit makes simulation especially valuable
When F1 visits a venue without a history of Grand Prix running there, teams lack the usual reference point of previous F1 event data from that circuit. They still need to form an initial view of what the car may require and what the drivers will encounter. That view has to be estimated before the weekend and revised once real track running starts.
Formula 1’s 2023 account of how teams planned for the Las Vegas race with no historic data describes that planning challenge. Simulation can help teams investigate a new circuit and prepare drivers, but it cannot create a record of real F1 running that does not yet exist. A new venue therefore sharpens the need to separate an informed estimate from an established trackside fact.
The Madring preparation report illustrates the driver side of this problem: simulation provided a way to accumulate virtual experience before the circuit’s first race weekend. Once the cars run there, the team can compare that preparation with what the circuit and car actually produce, then adapt its expectations. The new-circuit advantage is not that the simulator knows the unknown; it is that the team can begin the weekend with more questions considered.

Why energy management mattered in the 2026 Madring preparation
Formula 1’s September 2026 Madring report said the complexity of energy management under the 2026 rules made simulator sessions more useful and critical for drivers. This is a specific observation about that venue and rules context, not evidence that every team’s program or every circuit puts the same emphasis on energy management.
The broader lesson is that simulator value can depend on what makes a particular weekend demanding. A venue with unfamiliar features, or a rules context that creates additional decisions for drivers, may give the team more reason to prepare virtually. The public report does not set out a universal energy-management curriculum or quantify a performance gain, so neither should be inferred from the statement.
What simulation cannot guarantee
Correlation with the real car is decisive
A virtual result is only as useful as its relationship to the real car for the issue under consideration. Teams compare the modeled world with real-world running, and driver feedback helps them decide whether the simulator’s behavior matches what the driver experiences on track. When the comparison is poor, the team must treat the virtual result cautiously and adjust its assumptions rather than forcing the real car to conform to it.

Track running remains the test
The feedback loop is not a formality. A driver’s real-car feedback and the data gathered at the circuit can expose a mismatch between preparation and reality. Teams then make further setup decisions based on what the weekend has actually shown. Simulation can reduce uncertainty before that point, but it cannot remove the need to learn from the track.
A simulator is not the same as a consumer racing game
Consumer racing games may model racing or present setup and strategy choices, but that does not make them equivalent to the proprietary engineering environments used by F1 teams. Formula 1’s F1 Manager 2022 preview, for example, describes game mechanics for setup and tyre strategy. That establishes what the game offers as entertainment; it does not establish that it substitutes for a team’s driver-in-the-loop simulator or engineering model.
What is—and is not—publicly known
Public Formula 1 and FIA material supports a clear account of the simulator’s broad role: drivers can learn a circuit, engineers can investigate car and setup questions, and the team can refine decisions using track data and feedback. It also supports the distinction between interactive driving simulation and CFD, and identifies the special planning challenge posed by a new venue.

Nor does it provide an exact, named statistic for hours of simulator work, performance gains, laps per driver or simulator accuracy. The “thousands of laps” wording in the 2026 Madring report is qualitative and should remain qualified as such. Those limits do not make simulation’s role mysterious; they mark the boundary between a well-supported explanation of what teams use it for and unsupported claims about exactly how each team does it.
