MONTVALE, N.J. (Sept. 14, 2000) -- A Formula One World Championship (F1) grand prix runs approximately 200 miles and takes up to two hours to complete, with racing machines travelling at speeds of more than 200 mph. Yet it's the time these cars spend standing still that can determine the outcome of the race.
Pit stops for fuel and tires are a critical part of the competition. In F1, more than 20 people work on the car, and stops last about seven seconds -- pretty quick when compared with CART (12 seconds) or NASCAR (17 seconds). Yet for the driver and his crew, it can seem like an eternity.
"You've only got to have one little thing go wrong somewhere, and the whole weekend could be wasted," said David Ryan, manager for the defending champion West McLaren Mercedes team with drivers Mika Hakkinen and David Coulthard. "There are any one of 20-odd people who could make a mistake."
"Pit stops are a stressful time for the driver as well," Hakkinen agreed. "As you are coming off the track, you are preparing yourself for what is going to happen next. Every action is amplified because it all happens so quickly."
The championship-winning West McLaren Mercedes team prepares by performing practice pit stops up to 30 times on Thursday evening of the race weekend. The manual jacks used in F1 -- on top of the long days spent building the cars -- put an enormous demand on crew members for strength, speed and stamina. But a quick stop can mean gaining several positions on the track, and therefore mean the difference between victory and defeat.
"You can tell if you've had a quick pit stop," Coulthard said. "Everything just gels. When you get away smoothly and back onto the track ahead of the opposition, you know the guys on the crew have just worked another miracle."
The West McLaren Mercedes team will compete at the United States Grand Prix at Indianapolis Motor Speedway on Sept. 24 as Hakkinen and Coulthard vie for the coveted Drivers' Championship and McLaren Mercedes seeks its second Constructors' Championship title in three years. The race will mark the return of F1 to U.S. soil for the first time in nine years.
