Refueling

Refueling in motorsport is the process of adding fuel to a race car's tank during a pit stop to keep the vehicle running throughout a race.

When race cars compete, they burn through fuel quickly due to high speeds and demanding engine performance. Since most race cars can't carry enough fuel to complete an entire race, drivers must make pit stops to refuel. This happens in a designated area called the pit lane, where trained crew members use specialized equipment to pump fuel into the car as quickly and safely as possible.

Refueling is a critical part of race strategy. Teams must carefully calculate how much fuel their car uses per lap and decide the best times to pit for fuel. Making fewer fuel stops can save time, but running out of fuel means certain defeat. Some teams try to stretch their fuel further by having drivers use fuel-saving techniques, like coasting more or using less aggressive acceleration.

The refueling process varies between different types of racing. In IndyCar racing, teams regularly refuel during races as part of their strategy. Rally racing often includes designated refueling zones where drivers can add fuel between stages. Endurance races, which can last many hours, require multiple refueling stops to complete the distance.

Safety is extremely important during refueling operations. Fuel is highly flammable, so racing organizations have strict rules about how refueling must be done. Crew members wear special protective equipment, and the fuel systems are designed to prevent spills and fires. Some racing series have banned refueling entirely due to safety concerns - Formula 1 stopped allowing refueling in 2010.

Not all motorsports allow refueling during races. When refueling is banned, teams must start with enough fuel to finish the race, which adds weight to the car and affects performance. This creates a different type of strategic challenge for teams to manage.
