Quality
Rookie winners Inaugural race inclusive, ten drivers have won the race in their first start*, and one driver has won it in his first two starts. Rookie winners have occurred in ten out of one hundred races, 10%, in two consecutive years twice (1913 — 1914, 2000 — 2001), and in three consecutive years once (1926 — 1928).
* Mauri Rose's 1947 victory occurred six years after his co-victory with Floyd Davis in 1941, but only two races later due to the cancellation of the race, 1942—1945, due to World War II.
Most races between first and last victories Five drivers have won multiple victories across a time period of at least ten races.
* Scott Brayton qualified for the pole position in 1996, but was killed in a practice session accident nine days before the race in a backup car. Tony Stewart, the second qualifier, moved onto the pole position Brayton's stead, while Danny Ongais, per regulations, started the pole-winning car from the final starting position.
Most races between pole position qualifications Five* drivers have intervals between pole positions extending five or more races.
* Rex Mays' 1948 pole position qualification occurred eight years after qualifying for it in 1940, but only four races later due to the cancellation of the race, from 1942—1945, due to World War II.

Drivers who crashed while leading during final one hundred miles of race (Lap 160+)
1931: Billy Arnold - Arnold charged from 18th starting position to lead the race by lap 7. Arnold, who had dominated the 1930 race (led 198 laps), proceeded to lead the next 155 laps, and built up a five-lap lead over second place. His rear axle broke on lap 162. He spun in turn four, was hit by another car, and went over the outside wall. One of his errant wheels bounced across Georgetown Road, and struck and killed a 12-year-old boy, Wilbur C. Brink. Arnold suffered a broken pelvis, and his riding mechanic, Spider Matlock, broke his shoulder.
1952: Bill Vukovich - Vukovich led 150 laps, and was leading on lap 192 when a steering linkage failed. Vukovich nursed his car to a stop by driving up against the outside wall at the end of the back straightaway at the beginning of turn three, preventing other drivers from getting involved in the incident.
1989: Al Unser Jr. - On the 199th lap, Al Unser Jr. was leading Fittipaldi down the backstretch. The two cars weaving through lap traffic, and Fittipaldi dove underneath Unser exiting turn two. Racing side-with Unser drawing back ahead by a nose entering turn three, the two cars touched wheels, and Unser spun out, crashing into the outside wall. Fittipaldi coasted around the final lap under caution to score his first race victory.
1994: Emerson Fittipaldi - while leading the race on lap 184, Fittipaldi was attempting to lap his teammate Al Unser Jr., who was running second. Coming out of turn four, Fittipaldi's left wheels touched the rumble strips on the inside, causing the left side tires to lose adhesion, and the rear of the car to swing wide at the turn exit, resulting in the rear tagging the outside wall and knocking Fittipaldi out of the race. Unser Jr. went on to win.
2002: Tomas Scheckter - After leading 85 laps during the race, the rookie was leading on lap 173. Coming out of turn 4, he slid high and smacked the outside wall down the frontstretch.
2011: J. R. Hildebrand - During the final ten laps, a sequence of green flag pit stops shuffled the field. Rookie J. R. Hildebrand was attempting to stretch his fuel to the finish, and took over the lead with just over two laps to go. On the final lap, he was leading going into the final turn, when he came up on the lapped car of Charlie Kimball, who was slowing to the inside. Hildebrand went high, got into the "marbles," and smacked the outside wall. Without steering, and only on three wheels, his car slid down the frontstretch towards the finish line and the checkered flag. However, Hildebrand was passed by Dan Wheldon on the final 1,000 feet and Hildebrand finished second.
