Early years winning the
1912 Indianapolis 500 The
Indianapolis Motor Speedway complex was built in 1909 as a gravel-and-tar track and hosted a smattering of small events, including ones for
motorcycles. The first long-distance event, in "fearful conditions", was the 100-lap
Prest-O-Lite Trophy in 1909, won by
Bob Burman in a
Buick. The breakup of the track surface led to two fatal accidents in the first two long-distance events (a and , which was shortened to after two severe wrecks). The fact that these spectacles had attracted 15,000 paying customers (and crowds of up to 40,000) persuaded principal owner
Carl G. Fisher to spend $155,000 on repaving the track with 3.2 million bricks; he also added a tall concrete wall around the track's circumference. and a spectacular
purse of $25,000,
equivalent to of pure
gold. (as it was known from its inception in 1868 to 1967, when federal law made "Memorial Day" the official name), run to a maximum engine size formula. Harroun (with relief from
Cyrus Patschke) was declared the winner, although
Ralph Mulford protested the official result. Eighty thousand spectators were in attendance, and an annual tradition had been established. Many considered Harroun to be a hazard during the race, as he was the only driver in the race driving without a
riding mechanic, who checked the oil pressure and let the driver know when traffic was coming. In 1912, the purse was raised to $50,000, This second event was won by
Joe Dawson in a
National, after
Ralph DePalma's
Mercedes broke. For musical entertainment before the start of the race, the
Purdue All-American Marching Band has been the host band of the race since 1919. In 1946, American
operatic tenor and car enthusiast
James Melton started the tradition of singing "
Back Home Again in Indiana" with the
Purdue Band before the race when asked to do so on the spur of the moment by Speedway president
Tony Hulman. This tradition has continued through the years, notably by actor and singer
Jim Nabors from 1972 until 2014. Nabors announced in 2014, citing health-related reasons, that the 2014 Indy 500 would be the last at which he would sing the song. In 2015, the
a cappella group
Straight No Chaser sang the song before the race, and in the two races held after Nabors' retirement (and before he became the regular singer), the singing of the song was done on a rotating basis, with the Spring 2014 winner of
The Voice Josh Kaufman performing in 2016. However, the Speedway has returned to a standard singer with
Jim Cornelison doing it since 2017.
Miller and Offenhauser entered by Don Lee at the
1947 Indianapolis 500 with
Duke Nalon as driver Following the European trends, engine sizes were limited to during 1920–1922, for 1923–1925, and in 1926–1929. A
supercharged car, ID, first won the race in 1924. The engines powered another seven winners until 1938 (two of them, 1930 and 1932, in Miller chassis), then ran at first with stock-type motors before later being adjusted to the international 3.0-liter formula. After purchasing the Speedway in 1927,
Eddie Rickenbacker prohibited supercharging and increased the displacement limit to , while also re-introducing the riding mechanic.
European incursions and links to Formula One Meanwhile, European manufacturers, gone from the Indianapolis 500 for nearly two decades, made a brief return just before
World War II, with the competitive
Maserati 8CTF allowing
Wilbur Shaw to become the first driver to win consecutively at Indianapolis, in 1939 and 1940. , these remain the only Indy 500 victories obtained by fully Italian cars. With the 500 having been a part of the
World Drivers' Championship between 1950 and 1960,
Ferrari made a discreet appearance at the 1952 event with
Alberto Ascari, but European entries were few and far between during those days. Among the Formula One drivers who did drive at the speedway was one-time world champion
Italian Giuseppe Farina, who failed to qualify for the 1956 and 1957 races, and five-time world champion
Argentinian Juan Manuel Fangio, who failed to qualify for the 1958 race. It was not until the Indianapolis 500 was removed from the World Championship calendar that European entries made their return. In 1963, technical innovator
Colin Chapman brought his
Team Lotus to Indianapolis for the first time, attracted by the large monetary prizes, far bigger than the usual at a European event. Racing a mid-engined car,
Scotsman Jim Clark was second in his first attempt in 1963, dominated in 1964 until suffering suspension failure on lap 47, and completely dominated the race in 1965, a victory which also interrupted the success of the Offy, and giving the 4.2-liter
Ford V8 its first success at the race. The following year, 1966, saw another British win, this time
Graham Hill in a
Lola-
Ford. The Offenhauser engine was also paired with a European maker,
McLaren, obtaining three wins for the chassis, one with the
Penske team in 1972 with driver
Mark Donohue, and two for the McLaren works team in 1974 and 1976 with
Johnny Rutherford. This was also the last time the Offy would win a race, its competitiveness steadily decreasing until its final appearance in 1983. American drivers continued to fill the majority of entries at the Brickyard in the following years, but European technology had taken over. Starting in 1978, most chassis and engines were European, with the only American-based chassis to win during the CART era being the Wildcat and
Galmer (which was technically built in
Bicester, England) in 1982 and 1992, respectively. Ford and
Chevrolet engines were built in the UK by
Cosworth and
Ilmor, respectively. As of 2025, the most recent active Formula One driver to have entered the 500 is
Fernando Alonso, who drove in the
2017 race. Alonso was the first Formula One driver to enter the 500 while competing in F1 since
Teo Fabi in
1984.
World Series driving the
Penske PC-23 at the
1994 event After foreign cars became the norm, foreign drivers began competing in the Indianapolis 500 regularly, choosing the United States as their primary base for their motor racing activities.
Brazilian Emerson Fittipaldi,
Italian Teo Fabi, and
Colombian Roberto Guerrero were able to obtain good outings in the 1980s, as was
Dutchman Arie Luyendyk. In 1993,
reigning Formula One World Champion
Nigel Mansell shocked the racing world by leaving Formula One for
CART. While he came in only third in
the 500, he won the
1993 CART championship. Foreign-born drivers became a regular fixture of Indianapolis in the years to follow. Despite the increase in foreign drivers commonly being associated with the CART era, three of the first six
Indianapolis 500 winners were non-American drivers.
Split Era For the 1996 racing season, Speedway owner Tony George formed his own racing series, the Indy Racing League (IRL), making the 500 its marquee event. The most popular drivers and teams in open-wheel racing remained with
CART, setting the split in motion. (See more under
Race Sanctioning.) The two series unified in 2008 ending the split. The damage to open-wheel racing caused by the split has been termed by many sports writers as "immeasurable." During this time, the Indianapolis 500 lost fans failing to sell out again until the 2016 running. NASCAR's Daytona 500 overtook the Indianapolis 500 as the most watched auto race on television until 2011. NASCAR's
Brickyard 400 in the opinions of some fans and media writers overtook the Indianapolis 500 until a 2008 tire disaster in the 400. In 2005,
Danica Patrick and "Danica-mania" brought more attention back to the 500. While Patrick was not the first woman to race at Indy, she was the most popular and became the first to lead laps.
Centennial Era pace setter used in
1963 in the 47th running of the Indianapolis 500 In 2009, the Indianapolis Motor Speedway began a three-year-long "Centennial Era" to celebrate the 100th anniversary of the opening of the track (1909), and the 100th anniversary of the
first Indy 500 (1911). As a gesture to the nostalgic
Centennial Era celebration (2009–2011), tickets for the
2009 race donned the moniker "93rd 500 Mile International Sweepstakes". It is the first time since 1980 that the "Sweepstakes" title has been used. In May 2009, the ordinal (93rd) was used very sparingly, and for the first time since 1981, was not identified on the annual logo. Instead, in most instances in print, television, and radio, the race was referred to as the "2009 Indianapolis 500". Since the race was not held during the United States' participation in the two World Wars (1917–1918, 1942–1945), the advertised Centennial Era occurred during the 93rd to 95th runnings. To avoid confusion between the 100th anniversary, and the actual number of times the race has been run, references to the ordinal during the
Centennial Era were curtailed. In the
2014 meeting, the road course became part of the race meeting for the first time. The
GMR Grand Prix road course event, and the three upper tiers of
Road to Indy, participated in road course events at the Speedway during the first week of activities. Six years later, in
2016, the race celebrated its 100th running with about 350,000 in attendance and an announced sellout. Four local actors were hired to portray the Founding Four of James Allison, Carl Fisher, Frank Wheeler, and Arthur Newby during multiple Centennial Era events and the 100th race. Harold Hefner (Allison), Tom Harrison (Fisher), Jeff Angel (Wheeler), and Matthew Allen (Newby). In 2020, the race was delayed for the first time from its usual Memorial Day running to August due to the
COVID-19 pandemic. There was no audience in attendance, so as to comply with pandemic guidelines. The road course race was moved to the NASCAR weekend in July, and the support races on the road course moved to its own September weekend. As races were cancelled because of local restrictions, the Speedway added two more road course races in October as part of the
Intercontinental GT Challenge meeting, where attendance was capped to 10,000 per event. In 2024, the race was delayed for over four hours due to heavy rain and thunderstorms in the area.
Race name The race was originally advertised as the "International 500-Mile Sweepstakes Race" From 1920 to 1980, the race officially reverted to the "International Sweepstakes" moniker, as printed on the tickets and other paraphernalia, with slight variations over the years. Following
WWII, the race was commonly recognized as "The 500", "The 500-Mile Race", "Indianapolis 500-Mile Race", "Indianapolis 500", or the simple form "Indy 500". Usually the
ordinal (e.g. "50th") preceded it. Often the race was also advertised on the radio as the "Annual Memorial Day race", or similar variations. By the late 20th century, the term "Indy 500" had slowly emerged as the most common and most popularly used moniker. As such, since 2016, the official race logo has used the contemporary and colloquial term "Indy 500". For the
1981 race, the name "65th Indianapolis 500-Mile Race" was officially adopted, with all references as the "International Sweepstakes" dropped. Since 1981, the race has been formally advertised in this fashion, complete with a unique annual logo with the ordinal almost always included. Around that same time, in the wake of the
1979 entry controversy, and the formation of
CART, the race changed to an invitational event, rather than an
Open, rendering the "
sweepstakes" description inappropriate. For nearly a century, the race eschewed any sort of
naming rights or
title sponsor, a move, though uncommon in the modern sports world, that was well received by fans. This tradition finally ended in
2016 when a presenting sponsor, PennGrade, was added for the first time. In the 21st century, the facility has also slowly added sponsorship ads on the retaining walls and infield grass. The
Borg-Warner Trophy, introduced in 1936, proclaims the event as the "Indianapolis 500-Mile Race", with no reference at all to the name "International Sweepstakes".
