Content:  Toyota-affiliated tracks are less likely to use the Toyota Tundra, but prefer marketing the Camry Hybrid. However, Ford and Toyota manufacturer sponsored tracks will prefer the Mustang and Camry, respectively, instead of a truck, and occasionally, pickup trucks have been used as pace vehicles for Cup Series and Xfinity races. Since NASCAR does not allow speedometers or electronic speed limiting devices, the pace car circles the track at pit road speed during the warm-up laps. This allows each driver to note the RPM at which pit road speed is maintained. Drivers exceeding that speed on pit road will be penalized, typically a "drive-through" or "stop and go" penalty, costing them valuable track position. Since mid-2004, NASCAR

Rather than providing a fleet of Vipers, Chrysler provided numerous Stratus, Intrepids, and Special Edition Rams for festival use. The replica pace cars and the festival cars are usually worth significantly less than the actual car used to perform the pace car duties. Few festival cars may actually have been driven on the track. Actual pace cars are rare and most are kept and owned by the Speedway museum and the manufacturers. Traditionally, the make of the pace car has always been a domestic American brand. In 1991, the Dodge Stealth was originally named the pace car. However, the UAW, along

Content:  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

The average number of pace laps is three, but there can be more or less depending on a wide variety of circumstances and conditions, including but not limited to track length, track drying efforts after rain, or if a car has a problem and stops on the track during those pace laps. At the end of the pace laps, the field will partake in a rolling start. If the last lap of the race is started under caution, the race will be extended per NASCAR Overtime. Once the track is clear, the field will be given the green flag 
Title: Indianapolis 500 pace cars
Content:  The Indianapolis 500 auto race has used a pace car every year since 1911. The pace car is utilized for two primary purposes. At the start of the race, the pace car leads the assembled starting grid around the track for a predetermined number of unscored warm-up laps. Then if the officials deem appropriate, it releases the field at a purposeful speed to start the race. In addition, during yellow flag caution periods, the pace car enters the track and picks up the leader, bunching the field up at a reduced speed. Prior to the first "500" in 1911, in the interest of safety, Indianapolis Motor Speedway founder Carl G. Fisher is commonly credited with the concept of a

Content:  Through 1978, the pace car was only used at the start of the race, and was not used during caution periods. Since 1979, the pace car has also been used to pack up the field during caution flag periods. The ceremonial driver drove only at the start of the race. During caution periods, when the pace car is utilized to pace the field, a trained official has been the driver. In some cases, the officials utilize two separate pace cars (exactly the same models) one each for the start of the race, and the caution periods. Currently, the pace car driver for the caution periods is the same driver who drives the pace car for the Indy Racing League during all other events.

Content:  Starting in the mid-1950s, the auto manufacturer who provided the official pace car started selling replica pace cars to the general public. In many cases, the official on-track pace car was modified from its street-legal counterpart. Strobe lights, rolls bars, multi-point harnesses, television camera mounts, two-way communication (for officials), and removing the air conditioning, are among some of the more routine modifications made for the actual pace car. Some official pace cars, however, have undergone extensive performance modifications, including suspension, transmission, or even engine modifications from their production counterpart (the 1990 Chevrolet Beretta is an example of this). Race-duty pace cars may also have the factory fuel tank replaced with a fuel cell, and usually

By 1994, almost every form of motorsport had adopted pit lane speed limits, following NASCAR's cue. NASCAR does not allow the use of pit road specific rev limiters as found in most other forms of racing. Allowing a pit road limiter would require the addition of several electronic components into the car, and NASCAR has long opposed the installation of electronics into cars, citing the decline of open wheel racing once technology was introduced. Since 2002, NASCAR has implemented a rule where all over the wall pit members are required to wear helmets,

Programs usually require interested residents to register as a pace car driver, sign a pledge to abide by the rules, and display a sticker on their vehicle".

Since 2002, Chevrolet has had an exclusive contract with the Speedway to provide the pace car and other official vehicles for the Indianapolis 500. Prior to that, series engine provider Oldsmobile (1997-2001) had a similar arrangement, and provided the pace car three times over a five-year period. Chevrolet has had a contract to provide the pace car for the Brickyard 400 since 1994. Since 1936, the winner of the race has traditionally been awarded a pace car. In some years, and in most cases for the past several decades, the winner is actually presented with one of the official street-legal pace car replicas.
