Push-to-Pass

Push-to-Pass is a motorsport system that gives drivers a temporary boost of extra engine power at the press of a button, making it easier to overtake other cars during a race.

When a driver activates Push-to-Pass, their car's engine produces more horsepower for a short period, typically lasting between 15 to 20 seconds per use. This extra power comes from different sources depending on the car - it might increase the turbocharger's boost pressure, allow the engine to rev higher, or use stored energy from a hybrid battery system.

The system is controlled by a button on the steering wheel, which is why it's sometimes called an "overtake button." Drivers don't get unlimited use of this feature - race organizers give each driver a specific amount of Push-to-Pass time or a set number of uses per race. For example, in IndyCar racing, drivers might get 200 seconds of extra power to use throughout an entire race.

Push-to-Pass serves multiple purposes during a race. Most commonly, drivers use it to pass slower cars ahead of them, since the extra speed makes overtaking much easier. However, drivers can also use it defensively to stay ahead of competitors trying to pass them, or simply to set faster lap times when needed.

Managing when to use Push-to-Pass becomes a crucial part of race strategy. Drivers and their teams must decide whether to save it for the end of the race or use it early to gain track position. Using it at the wrong time could leave a driver defenseless later in the race.

Several major racing series use Push-to-Pass systems, including IndyCar, Super Formula, and the Deutsche Tourenwagen Masters (DTM). Each series has its own rules about how much extra power is available and when drivers can use it, making the system an important part of modern motorsport competition.
