Formula 2 — officially the FIA Formula 2 Championship — is the FIA's main feeder series, one rung below Formula 1. It is a spec (one-make) championship: every team runs the same Dallara chassis, Mecachrome V6 turbo engine and Pirelli tyres, so results come down to the driver and team rather than the size of the budget.
F2 races on Formula 1 Grand Prix weekends, sharing the same circuits and putting rising talent on the same stage as the F1 paddock. The current championship was introduced in 2017, taking over from the long-running GP2 Series as the FIA's principal step toward Formula 1.
Because the machinery is identical across the grid, the category is built to reward pure driving craft — and it delivers: F2 graduates its stars straight into Formula 1, so the order here is often a preview of tomorrow's Grand Prix grid.
