F1 Boost Mode explained
The driver-operated maximum-deployment tool that is distinct from Overtake Mode.
Quick answer
Boost Mode lets the driver request maximum available engine-and-battery power at the press of a button, subject to the car's energy state. It can be used to attack or defend and does not require a one-second gap.
Boost versus Overtake
Overtake Mode is an eligibility-based additional allowance for a chasing car. Boost Mode is the driver's normal tactical deployment command and can help either side of a battle.
Why it is not unlimited
The battery is an energy store, not a permanent second engine. Using more now leaves less for later until harvesting replenishes it.
What viewers should watch
Onboard graphics and commentary may show when a driver deploys or saves energy. A car that looks passive on one straight may be preparing a stronger attack on the next.
