What this build simulates Continuous car movement, braking and acceleration, tyre wear and temperature, slipstream and dirty-air effects, passing lanes, pit entry, shared pit boxes and pit exit. Pace, car attributes and driver skill affect the same state used for timing.
Short-format assumptions 10 laps, seeded race weather scenarios with abstract wetness and forecasts, scaled tyre wear and fuel effect, estimated performance, illustrative pit-lane geometry, optional preset qualifying order and simplified overtaking. Two distinct dry compounds are required unless intermediates or wets have been used. Tyres fitted in a stop count when the car exits the pit lane. This fan format permits all three dry compounds and unlimited virtual tyre sets; event-specific allocation is not implemented.
Energy deployment, red flags, retirement classification, steward penalties beyond the tyre rule, full session simulation, full career management and highlight replays are future stages. This is an unofficial, unlicensed fan prototype; no official logos, car imagery or live data feeds.
Quick weekend Optional practice and Q1–Q3 build a grid before the race. Practice uses short, instantly resolved stints with fuel-adjusted pace, wear and imperfect balance feedback. Downforce and balance carry into qualifying and the race. Qualifying accounts for estimated traffic, release timing, track evolution and driver errors. Session windows follow the verified 2026 rules; the remaining mechanics are labelled game abstractions. Delegate either stage to keep the session short.
Development Cup HQ offers a fictional four-round Monza Development Cup with persistent budgets, designs, manufacturing, stores, separate car specifications and championship points. Resources, prices and upgrade attributes are game estimates. It uses Monza for all rounds, not the official F1 calendar. Advance workshop days deliberately; finished designs require manufacturing, and physical units must be fitted before qualifying. Practice comparisons require the same driver, setup, compound, fuel and stint length. Fitting is instantaneous in this slice. Detailed damage and repair manufacturing, staff, sponsorship negotiation, next-season research and full career progression are deferred.
Race weather and rivals Rain changes water accumulation, the drying line, tyre grip, temperature and wear. Intermediate and wet crossover points depend on condition and wear; wet tyres overheat on a dry track. The track shade follows simulated water levels. Forecasts extrapolate noisy current observations over two minutes and can miss arrivals or clearances. They are original game estimates, not real weather feeds or calibrated probabilities. Rivals use the same public weather forecast and visible pit activity, with different reaction times and margins. They can make poor calls. Aquaplaning and severe-weather suspensions remain deferred.
Incidents and race control New races enable limited incidents and race control; you can select clean mode before starting. Older saves keep clean mode. Seeded incident risk depends on pace pressure, weather, cornering and close side-by-side geometry. Kerb strikes and minor contact create wing/bodywork damage and momentum loss. There are no injury or retirement mechanics. At most two incident events are sampled per short race; some races stay clean. Damage indices are game abstractions, not measured percentages of a component.
VSC uses a common reduced speed profile rather than official ECU sector deltas. Its ending notice precedes green by 10–15 simulation seconds. The safety car uses an illustrative dispatch position ahead of the leader; the field physically forms a queue and the car follows the circuit and pit path. No wave-through or unlapping is implemented. Overtaking stays restricted through each car’s own control-line crossing after pit entry. Final-lap SC finishes remain under caution. Exact safety-car lines, official penalty procedures, red flags and full dispatch/garage animation are deferred. These are labelled simplifications of FIA 2026 B5.12–13, checked against issue 09.
Repairs are opt-in alongside a tyre change. Wing replacement adds service time and consumes a matching physical spare in the cup. Bodywork patching halves its remaining performance loss. Unrepaired player damage carries to the next round; HQ offers a paid one-day workshop repair, or you can replace a damaged wing with another specification before qualifying. Discarded wings leave stores permanently. Rivals have abstract repair supplies and no private knowledge of caution end times. Safety cars may extend a 1× session; use faster playback when desired.
Saving and recovery Pit plans default to manual calls; automatic calls must be explicitly enabled. Analysis records lap times and pit visits. Live rejoin and strategy numbers are estimates using current gaps and modelled tyre behaviour, not guarantees. Autosaves every five seconds of active play and when the app becomes hidden; returning starts paused. The previous save is retained for recovery. Browser storage can be cleared or unavailable. Export a JSON backup for durable recovery. New exports use save version 4, including damage, repairs and race-control state. Version-1 races migrate as dry standalone races; version-2 races retain weather and remain standalone. Version-3 cups retain progression and start in clean mode. Development cups carry the budget, queues, parts, standings and active race in the same save. Other unsupported versions are rejected; keep the original export.
Data and provenance 2026 roster verified 17 October 2026 against Formula 1. Names and team pairings are facts. Driver attributes, wet ability and car ratings are provisional estimates, separate from the engine. Monza length is official; community centreline data are not a survey of the 2026 circuit.
