Distinctive enough to have its own die-cast model, the '66 Cyclone GT pace car combined style, handling, and performance along with the prestige of leading one of the world's most famous races. The original was driven by Benson Ford, head of Lincoln Mercury at the start of the 1966 race. Before we tell you all about this particular example, it's important to know how the pace car came to be.

Almost as old as the automobile itself, the Indianapolis Motor Speedway began as a gravel and tar track in 1909. Racing conditions were hazardous and after several fatalities, track president, Carl Fisher, decided on a very expensive safety measure; paving the 2.5-mile track with an astonishing 3.2 million bricks! The gamble paid off and the smoother surface gave "The Brickyard" an enhanced status among the racing circuits of the day. To properly publicize his new track, Fisher focused on creating one major event, a 500-mile, 200-lap race that would test the endurance of both driver and car. On Memorial Day, May 30, 1911, the first "International 500-Mile Sweepstakes Race" (quickly abbreviated to the Indy 500) drew 80,000 spectators and established an annual tradition that continues today. During that race and every Indy 500 since, a pace car was used to control the pack, creating a parade lap to showcase the cars for the crowd and it allowed for a rolling start—something that Fisher considered safer for the drivers and spectators. He was behind the wheel of the very first pace car, a Stoddard-Dayton.

Pace cars continue to control the field today on the initial start, as well as on restarts, after caution periods. Rules prevent the drivers from passing the pace car or any other car during the yellow flag cautionary periods. While the pace cars quickly proved their worth on the track, they soon took on a life of their own, becoming sought-after choices by manufacturers eager for the publicity and prestige of having their vehicles in front of such a large audience.

Chosen two months prior to the event, the pace cars were always the highest horsepower versions available to ensure they could achieve the speeds necessary during the parade lap. Heavy-duty suspensions with slightly lower springs, beefy antisway bars, bigger brakes, and premium rubber were added in the early years to ensure that the cars could negotiate Indy's high-speed corners. While the race exposure was great publicity that spurred sales, it was also a double-edged sword with manufacturers going to great lengths to ensure that their cars performed well on the track during their moment of glory. Any type of failure at that point could be disastrous.

As you might expect, the amount of pre-race modifications for a pace car was not greatly publicized, since consumers expected the cars to be reliable without any special preparation. That was not always the case, however. When the Chevrolet Camaro was selected in 1969, a fleet of 130 pace car replicas was created to be used as courtesy and support vehicles during the event. Most of the changes were cosmetic, but the pair of actual pace cars received extensive modifications. Equipped with 375 hp, L89 V-8s and automatic transmissions, the cars were shipped to the GM Tech Center where the engines and transmissions were disassembled, thoroughly inspected, and reassembled. Aluminum heads were replaced with L78 cast-iron heads, a special 6-bolt COPO torque converter was installed, and JL8 four-wheel disc brake axles with 3.31 gears completed the mechanicals. All suspension components were magnafluxed and treated to ensure they would not fail during the race. They even went so far as to install pre-stretched drivebelts and aircraft-type hose clamps. As the automobile continued to evolve, however, fewer changes were necessary. Modern cars like the '10 Camaro selected last year needed virtually no pre-race performance enhancements to qualify, although all receive a careful inspection along with a distinctive paintjob that incorporates the traditional pace car logo on the sides and a specially designed light bar with strobes.
