1911–1956 Pace Car The pace car was used to take the starting field on one unscored lap. The field would use the lap to warm up their engines, tires, and then at the conclusion of the lap, at a prescribed speed, the pace car would pull off the track and allow for a rolling or "flying" start. Fisher himself drove the pace car in several early years, but it eventually became an honorary position, with invitations extended to former winners, notable figures in auto racing or the automobile industry. The invited driver was given the honor of "pacemaker," and manufacturers used the honor of providing the car as marketing exposure. During his tenure as Speedway president,
Tony Hulman rode in the pace car nearly every year, immediately after giving the command to start engines. His primary duty was to marshal the start and in some years, his responsibilities included operating a film camera that would be housed inside the car's trunk. Dating back to the very early years, the pace cars were often painted with special liveries complete with logos, lettering, pinstriping, and other decorative markings. In addition, sometimes flagpoles, lights, and other motoring paraphernalia were installed to further identify the pace car. Most manufacturers used the opportunity to showcase their higher end or luxury models. Since in the early years, the pace car was only used for one lap at the start (and not during caution periods), the need for a
high performance machine (i.e.,
sports car) was not necessarily the top priority. In many years, the pace car was a
convertible, which along with increasing the luxury status of the vehicle, it aided in the officials' ability to marshal the start.
1957–1976 Pace Car In most years through the early 1950s, the pace car led the field around the track for one warm up lap, and then the race began. The pace lap concept was popular with fans, as many drivers commonly waved at the fans and the rolling grid made for spectacular photographs. By 1957, the procedure was changed so the pace car led the field for two warm up laps. This allowed extra time to warm up the engines, oil temperatures, and tires, and allowed the drivers the chance to survey the conditions of the entire track at least once before receiving the green flag. This also allowed the fans on the main stretch (where the largest grandstands are located) to see the entire field parade by one time before the start. Previously only fans on other parts of the track got to actually see the grid go by for photographs and waving. For the 1957–1958 races, the grid was lined up and exited single-file from the newly constructed pit lane. The two laps allowed the field to properly form up, however, in practice it turned out to be difficult and both races saw incidents at the start. In 1959, the field went back to lining up the grid on the main stretch, and continues to do so to this day. By the late 1960s, not only would a special driver be behind the wheel of the pace car, but numerous celebrities would be invited to ride along as passengers. Automotive executives,
NASA astronauts, reporters from
ABC Sports and the
IMS Radio Network, and other celebrities were among those invited to ride in the pace car. In 1971, local Indianapolis Dodge dealer Eldon Palmer was involved in a crash driving the pace car. He crashed into a photographer's stand at the south end of the pit area, injuring several persons. In the years immediately following, the pace car driver utilized would only be an experienced race driver. Former Indy winner
Jim Rathmann served six times (and once for caution periods only). Celebrities
James Garner and
Marty Robbins were chosen in part due to their experience in racing.
1977–present pace car In 1977, the format was changed to three warm up laps - two "
parade laps" and one "pace lap". During the parade lap(s), often several replica festival pace cars join the field, usually carrying celebrities and/or special guest drivers. The 1978 race was the first to feature multiple pace cars on the track during the parade lap. Since 2010, the IndyCar "two-seater" (a retired Indy race car modified with a special passenger seat) has also been at the front of the field, carrying a celebrity or special guest. The non-participating vehicles pull off the track after one or two circuits, and the lone official pace car leads the field on the pace lap. In 2012, it was further expanded to four warm up laps (three "parade" laps and one "pace" lap), coinciding with the introduction of a new engine and chassis formula. Starting in about 1994, the field was observed to be quite straggled about during the parade lap(s), and often circulated the track single-file. Drivers were known to weave back and forth, sometimes vigorously, in an effort to build up tire temperature. On the final pace lap, the field would finally form up into the eleven rows of three on the backstretch, but oftentimes it was still loose and not in pristine order. This practice was often the subject of harsh criticism from fans and media, especially when the start was strung out single file, breaking tradition. In 2010, officials announced they were going to police the parade and pace laps closer, requiring the drivers to stay in the rows of three during the extent of the warm up period. In later years, the Speedway began experimenting with using
pop culture celebrities driving the pace cars, a change that has met with mixed responses from fans. Racers have taken the position in more recent years.
A. J. Foyt drove in 2011,
Dario Franchitti drove in 2014,
Jeff Gordon, a five-time
Big Machine Vodka 400 winner, drove in 2015, and with the new broadcast partner
NBC Sports, their motorsport broadcaster
Dale Earnhardt Jr., who made 16 Big Machine Vodka 400 starts and a two-time
Indiana 250 winning car owner at the Speedway, drove in 2019.
Extra pace laps 1957: A new state-of-the-art pit lane was built. For the first time, the pit area was separated from the racing surface. For 1957–1958, the field was lined up in single file on the pit lane, rather than the traditional 11 rows of three on the race surface. This required the cars to pull away, then assemble into formation. This caused tremendous confusion in 1958, as the front row escaped from the pace car, and the field needed an extra pace lap to assemble before the green was displayed.
1967: The race was red-flagged for rain after 18 laps. The conclusion of the race was moved to the following day. At the time, the pace car was not used for caution periods. However, officials decided to utilize the pace car for the resumption on lap 19. The original pace car driver
Mauri Rose drove the car for the restart as well. Two unscored laps (one parade lap and one pace lap) preceded the resumption at lap 19.
1970: Jim Malloy hit the outside wall in turn four as the field was about the take the green flag. The start was waved off, and the next time by, the field was red flagged to clean up the incident. The teams were allowed to replenish a few gallons of used up fuel, and a short time later, the field pulled away for two new pace laps.
1973: A crash occurred as the field was about to take the green flag. The start was red flagged, after driver Spike Galhausen, from Indianapolis, crashed into the outer wall warming his cold tires and the cars circulated around back to the pits. After clean up, the field restarted, with two pace laps before the green flag.
1986: Tom Sneva crashed on the backstretch on the pace lap. The start was waved off, and the next time around the cars were halted on the frontstretch with a red flag. During the cleanup, officials decided to replenish the teams' fuel tanks with 3 gallons of methanol. After that was completed, the field restarted, and took two warm up laps before the green flag.
1992: Additional pace laps were run (unscored) after
Roberto Guerrero crashed during a parade lap. Instead of halting the proceedings, officials decided to simply extend the number of warm up laps. The race itself ended up having 85 laps of yellow flag conditions, therefore the fuel allotment did not become a factor.
1997: Additional laps were run (unscored) due to a three-car crash on the original pace lap.
2009: When the field came out of turn four for the start, the field was not well aligned in the eleven rows of three. For the first time in modern history, the flagman decided to wave off the start, by displaying the yellow flag. The lap was not scored. The field re-formed, and received the green flag the next time by, with a slightly better formation. ==Caution periods==
