Indianapolis 500See also: Indianapolis 500 pace cars
The first use of a pace car in automobile racing was at the inaugural Indy 500 in 1911. The officials at the Indianapolis Motor Speedway have been selecting a pace car and its driver for the Indy 500 each year since that first race. The first pace car was a Stoddard-Dayton driven by Carl G. Fisher. In recent years Chevrolet models have been chosen as the official pace car, owing to the ability for them to be used at both major automobile races at the Speedway (typically Corvette at the 500 and Impala at the 400). The pace car is selected two months before the race runs, allowing the manufacturer of the selected pace car to produce replicas of that year's car, which sell at a marked premium to collectors and race fans. Pace car replicas are often seen on the streets of Indianapolis weeks before the race is actually held, and a celebrity driver is usually used for the start of the race only. For the 2012 Indy 500, the Chevrolet Corvette was chosen as the Official Pace Car with Guy Fieri to be the pace car driver.
Automakers compete for the prestige of having one of their models selected as the year's pace car for the publicity. In 1971, the move backfired as no automakers stepped up to provide a pace car. Instead, local Indianapolis-area Dodge dealers fulfilled the duty. Eldon Palmer, a local dealer, lost control of the Dodge Challenger pace car and crashed into a photography stand, injuring several people. The blame for the crash was never fully determined, as officials realized that an orange cone (or perhaps an orange flag), which was to identify Palmer's braking point, was accidentally removed.
In the last 50 years, the Pontiac Trans Am, Chevrolet Camaro, Chevrolet Corvette, Oldsmobile Cutlass, and Ford Mustang are the only models that have been selected as pace cars three or more times.
During the IndyCar Series season, however, Johnny Rutherford is the normal driver of the IRL pace car for all events. The pace car is deployed for debris, collision, or weather reasons. Since 1993, upon the waving of the yellow flag, pit road is closed until the pace car picks up the leader and he passes the pit entrance the first time, unless track blockage forces the field to drive through pit lane. Another duty of the pace car is to lead the field around the course on parade laps prior to the start of the race. These increase in speed, allowing for a flying start of the race.
Furthermore, two other rule changes have been implemented. Since 2000, with one lap to go before going back to green, the pace car pulls off the track in turn one rather than in turn four. The current leader of the race is then assigned the task of pacing the field back to the green flag. After much consideration, this rule was added to prevent a situation much like the one that happened in the 1995 Indianapolis 500, when Scott Goodyear passed the pace car going back to green. In 2002, another rule was added. With one lap to go before the green, the pace car waves by all cars (if there are any) between the pace car and the actual leader of the race. This allows for the leader to control the restart without lapped cars being in front of him. It also creates a strategy for cars to gain laps back, loosely resembling the "Lucky dog" rule. However, the cars who get waved around are not allowed to pit until the green flag restarts the race (so they do not get the advantage of getting their lap back AND a free pit stop).
