Pit Stop in 4 Seconds
From the Malaysian F1 Grand Prix at the Sepang International Circuit, Kuala Lumpur on April 10th, 2011, in which Sebastian Vettel emerged as the winner.
In motorsports, a pit stop is where a racing vehicle stops in the pits during a race for refueling, new tires, repairs, mechanical adjustments, a driver change, etc. By making pit stops cars can carry less fuel, and therefore be lighter and faster, and use softer tires that wear faster but provide more grip. In any racing series that permits scheduled pit stops, pit strategy becomes one of the most important features of the race; this is because a race car traveling at 100 mph (160 km/h) will travel approximately 150 feet (45 m) per second.
During a ten-second pit stop, a car’s competitors will gain approximately one-quarter mile (0.5 km) over the stopped car. However, the car that made the additional pit stop will run faster on the race track than cars that did not make the stop, both because it can carry a smaller amount (and thus lower weight) of fuel, and will also have less wear on its tires, providing more traction and allowing higher speeds in the corners.
