The Formula 1 race start is the most compressed moment of strategic and physical intensity in the sport. In the four to five seconds between lights out and the first braking point, positions are gained and lost that can determine the entire shape of a grand prix.
The modern F1 start procedure requires the driver to manage three simultaneous variables: clutch engagement, throttle position, and wheelspin. At the moment the lights go out, the driver must release the clutch from its pre-set launch position while progressively increasing throttle input, monitoring whether the tyres are spinning or gripping.
The launch control systems that many fans assume modern F1 cars use have been banned since 2008. All starts must be managed manually by the driver. However, the cars do have systems that can limit catastrophic wheelspin — the engine management software prevents spinning that would cause the driver to go nowhere.
The first corner is where a perfectly executed start can translate into positions that take the entire race to undo, or a poor start can be recovered. Hamilton's ability to gain positions at the start was a hallmark of his championship campaigns; Max Verstappen's aggression at Turn 1 — particularly at Bahrain and Saudi Arabia — became one of the defining narratives of the 2021 season.
