The race is run on a newer, modified layout of the circuit previously used for theFormula OneUnited States Grand Prix,and later theMoto GPmotorcycle event.From 2014 to 2016, the race was known as the Grand Prix of Indianapolis, and from 2015 to 2016 it was sponsored byAngie's List.For 2017, the Angie's List title sponsorship was dropped, and the race name was changed to the IndyCar Grand Prix. This was done in order to reduce confusion with the previous Formula One grand prix race that used to be held there, and to emphasize to fans that the race was part of the American-based IndyCar Series.[1]As of 2024, the race is known as theSonsio Grand Prixfor sponsorship reasons. A second road course race, theGallagher Grand Prixwas held during the summer as a support race for theNASCAR Cup SeriesVerizon 200 at the Brickyard.That race was run from2020until2023.

Background

edit
Flyover at the 2016 Grand Prix

In 2012, Hulman & Co., then parent company of theIndianapolis Motor Speedway,hired Boston Consulting Group to evaluate its business operations.[2]In their report, one of their suggestions was to explore the possibility of hosting an IndyCar Series race on the road course at Indy.[3]The modernFIA Grade Oneinfield road coursehad opened in 2000, and was initially used for theUnited States Grand Prixfrom 2000 to 2007. Later, it was used forMoto GP,andGrand Am.The layout for the infield road course was originally designed in 1992 by Kevin Forbes during the reconstruction of theBrickyard Crossinggolf course.[4]It had already gone through some various improvements, most notably in 2008 when the "Snake Pit" segment was added in the infield of oval turn one. Indy cars had never raced on the road course layout, sticking only to theoval circuitfor theIndianapolis 500,but their support series, theIndy Lights,had raced there four times. Occasionally Indy cars used the Indianapolis road course as a test facility, since many teams are headquartered in the Indianapolis area.Dan Wheldonnotably tested theDW12chassis at the course in September 2011.

In September 2013, an IndyCar feasibility test was conducted on the Indianapolis Motor Speedway road course.[5][6]The test yielded positive results. Speculation immediately began to grow about a possible race for 2014, either as a May "doubleheader" event with the Indy 500, or a stand-alone race in the fall. The inaugural race was announced on October 1, 2013, and was scheduled for early May.[7]The decision was made to utilize the course in a clockwise layout, and to re-work certain parts of the track.

Course changes

edit

In October 2013, a construction project began to reconfigure the road course layout in order to the make the circuit more competitive, better for fans, and more suited forIndy cars.The entire road course portion was repaved, while several segments were modified. Corner one of road course was changed to a 90-degree turn with a raised curb on the inside. The road course portion inside oval turn four was revised to bypass two slow turns, and effectively lengthened the Hulman Boulevard backstretch. At the end of the Hulman Blvd. backstretch, a new 90-degree left corner leads to a new series of faster turns behind theMuseum.Rather than follow original corner 13 (oval turn 1) like the U.S. Grand Prix did, the IndyCar circuit mimics the motorcycle course, and utilized the "Snake Pit" infield complex. Two of the tighter, sharper, corners (utilized by the motorcycles) were bypassed and replaced with a single 90-degree right turn leading to the pit entry. The new course distance measures 2.439 miles (3.925 km).

Schedule

edit

From 2014 to 2019, and again since 2021, the IndyCar Grand Prix has been scheduled for the Saturday two weeks before theIndianapolis 500.The race effectively serves as an "opening weekend" for the month of May activities at the Speedway. The race is on the Saturday that was once used for Indy 500pole day(1952–1997 & 2001–2009), and in other years the opening day of practice (1998–2000 & 2010–2013).

Saturday was selected for the race due to the fact that the Sunday two weeks before the Indy 500 is usuallyMother's Day(a day usually avoided by motorsports). In addition, the track is closed on Sunday to allow crews to convert the track back to the oval layout, and to allow teams to convert their cars from road course to oval configuration. Practice for the Indy 500 on the oval begins the following day on Monday or Tuesday.

On April 6, 2020, theIndyCar Seriesannounced that as part of revisions to the2020 seasondue to theCOVID-19 pandemic,it would add a third event at the Indianapolis Motor Speedway to the schedule known as theIndyCar Harvest GPon the road course. Later, it was expanded to become a doubleheader on October 2–3. Its naming pays tribute to theHarvest Auto Racing Classic,and served as a support event accompanying the inaugural Indianapolis 8 Hour of theIntercontinental GT Challengecircuit. It was the second road course race at IMS for the 2020 season, alongside the GMR Grand Prix (which was moved to July 4 as part ofNASCAR'sBrickyard 400weekend).[8]

For2021,the GMR Grand Prix moved back to its normal date in early May, with the pandemic-induced meeting held during theNASCARVerizon 200weekend continuing. During the NASCAR weekend, the race is an early afternoon Saturday event with the NASCAR XfinityShell 150as the nightcap.Big Machine Spiked Coolerssponsored the first event.[9]

On April 29, 2022, theArthur J. Gallagher & Co.was named sponsor of the summer race.[10]

On November 1, 2023,Sonsio Vehicle Protectionwas named the sponsor of the May race.[11]

Indy NXT / Indy Lights

edit

TheIndy NXT Indianapolis Grand Prixis a pair of twin races in theIndy NXTseries, held on the combined road course at theIndianapolis Motor Speedway.For the first three years of its existence, theIndy Pro Serieswas contested onoval tracksonly. All Indy Pro Series races were run as support to IRL/IndyCar Series events. Road course and street course events were added to both series in 2005, and the series was renamed to Indy Lights beginning in 2008.

The race was first introduced as theLiberty Challenge(2005–2007) and was held as a support race to theFormula OneUnited States Grand Prixat Indianapolis. The Liberty Challenge was the first Indy Pro Series race which was not run as support to anIndyCar Seriesweekend. This move allowed the Indy Pro Series drivers valuable exposure in front of the Formula One teams and fans. Some drivers, such asGraham Rahal,ran this race as a one-off, while running full-time in other series (such as theAtlantics). The U.S. Grand Prix at Indianapolis ended after 2007, and the Liberty Challenge event was put on hiatus.

An Indy Lights (now Indy NXT) race on the Indianapolis road course was revived in 2014 as part of the new IndyCar Grand Prix weekend. However, the original Liberty Challenge name was dropped. In addition, the race was now being contested on the newer 2.439-mile road course layout used by the IndyCar Series.

History

edit
An early rendering of a combined road course layout, ca. 1909.

The addition of the Grand Prix of Indianapolis established two Indy car races in the Indianapolis area. It was the first time since 1970 that multiple Championship/Indy car races are being held in the greater Indianapolis area. Through 1970, the Indy 500 was accompanied by theHoosier Hundredat theIndiana State Fairgrounds,which at the time was a National Championship event. TheHoosier Grand PrixatIndianapolis Raceway Parkwas held as a USAC Champ Car race from 1965 to 1970.

When theIndianapolis Motor Speedwaywas under construction in 1909, the original plans included acombined road courselayout.[13]This would have allowed for both oval track and road course events. According to historianDonald Davidson,some initial grading appears to have been completed for what would have been a 5-mile layout, but plans for the road course were scrapped during construction.[14]It was not until 1998 that plans for a road course layout at the facility were revived, when theUnited States Grand Prixwas announced.

In 1990, a street circuit in downtown Indianapolis was proposed,[15][16]with a goal of attracting a Formula One or CART Indy car race. The layout encompassed roads near theHoosier DomeandIndianapolis Zoo.The plan never materialized.

The 2020 season marked four races were held in Indianapolis, with the three road course events –one during the NASCAR and two during the Intercontinental GT Challenge meeting– as a result of pandemic-related postponements. For 2021, the two races are held during the Month of May and the NASCAR weekend.
