Detroit Grand Prix (IndyCar)

The Detroit Grand Prix (currently branded as the Chevrolet Detroit Grand Prix presented by Lear Corporation for sponsorship reasons) is an IndyCar Series race weekend held on a temporary circuit in Detroit, Michigan. The race has been held from 1989 to 2001, 2007 to 2008, and since 2012. Since 2012, the event has been scheduled for the weekend immediately following the Indianapolis 500.

The origins of the event date back to the

Open wheel racing in Detroit dates back to the 1920s–1950s, when AAA held the Detroit 100 at the Michigan State Fairgrounds Speedway. AAA also held one five-mile (8 km), non-championship race at Grosse Pointe in 1905.

The Raceway on Belle Isle is classified as an

The race dates back to 1982 when it was a Formula One World Championship event held on the Detroit street circuit encompassing the Renaissance Center. The original circuit was 2.493 miles (4.012 km) with seventeen corners and proved to be even slower than Monaco. The rough, demanding course included a railroad track crossing and mimicked Monaco, with a tunnel on the main straight. While officially the Detroit Grand Prix, it was also referred to as the United States Grand Prix East because there were multiple Grand Prix races in the U.S. at the time. By the time of the 1988 race, the FIA, the governing body of Formula One, had declared the street circuit's temporary pits and garages were not up to the required standard. The race was already the least popular Grand Prix on the calendar and after a very difficult 1988 Grand Prix the drivers became outspoken with their dislike of the event.

For

In October 1988, the plan to move to Belle Isle was scrapped.[7]^[8] Formula One left Detroit permanently, and a short time later, it was officially announced that the U.S. Grand Prix was moving to Phoenix.

It was in Detroit in

For

The 1991 event was perhaps the last straw in what was an embarrassment for the organizers. In addition to a disintegrating track made worse by suffocating heat and humidity, it saw Mario Andretti crash his Lola head-on into a tow truck. The safety crew was attempting to remove Dennis Vitolo's stalled car from a blind corner at St. Antoine and East Jefferson Streets. Seconds later Michael Andretti came onto the scene, and crashed into Vitolo's car attempting to avoid his father's wrecked car. Ultimately, promoters considered the downtown circuit a money-loser, and claimed it was suffering from poor television ratings with its Father's Day date (up against the U.S. Open).^[10][11]

Belle Isle: 1992 to 1997

Beginning in

In 1998, the course layout was modified to eliminate the slow "Picnic Way" segment and series of corners. Instead, the course continued straight along Central Avenue to create a long, fairly-wide straightaway leading into a competitive passing zone. The track then measured 2.346 miles (3.776 km). The revised layout was praised by competitors as being an improvement over the original (1992–1997) course. However, pavement transitions from asphalt to concrete were being blamed for an increase in incidents due to slickness.[14]

The

Support races for the Detroit Grand Prix included the Motor City 100 for the SCCA Trans-Am Series, and the Neon Challenge celebrity race. Scenes from the film Driven were filmed during the race weekend in 2000.^[15]

The event, along with the

Demise: 2001

Even though the track was a temporary street course, it became known as The Raceway on Belle Isle. As the years went by, the track was increasingly criticized for its narrowness, poor access, and its overall uncompetitive nature. The once smooth surface was aging in the harsh Detroit winters, and along with it came bumps, cracks and potholes. The circuit gained a reputation of being the "worst" and "least popular" venue on the entire schedule.^[16] In 1997, it was noted that race winner Greg Moore started seventh and did not pass a single car competitively out on the track for position all day.^[17][18] Participants also disliked the facility because of its lack of paved areas for support activities. Paddock areas were often muddy and unable to accommodate the teams.

After the 2001 race, CART's contract with Belle Isle expired. Attendance had been noticeably slipping.^[19] Negotiations to continue the event went over the summer,^[20] but eventually stalled. Organizers briefly entertained an idea to return to the old downtown circuit,^[21] but those plans were quickly scuttled.^[22] The series chose to drop the race from the schedule and the event went on hiatus.

IndyCar Series

2007 to 2008

In 2006, Roger Penske spearheaded talks to revive the race for 2007 as part of the ALMS and IndyCar Series schedules. Penske had recently experienced tremendous success as head of the Super Bowl XL Detroit Metro Host Committee. On September 29, 2006, it was announced that the Detroit Indy Grand Prix would return as the tenth race of the ALMS's 12-race season and penultimate race of the IndyCar Series' seventeen-race schedule.

To improve access to the track, a park-and-ride system, similar to what was used at Super Bowl XL, was implemented. Further paddock and track work was completed before the race. The 2007 event attracted a strong crowd, and was considered a success. It was held again in 2008. During this period, the event utilized the original (1992–1997) course layout, with some minor improvements. Some of the barriers were moved back, particularly inside the apexes of some of the turns, to effectively widen some curves and improve sight lines. Some barriers, including the metal guardrail on the pit straight, had been entirely removed.

On December 18, 2008, the scheduled race for 2009 was canceled. The ongoing

For the 2012 season, the race on Belle Isle was revived for second time.[25]^[26] The event was situated on the weekend immediately after the Indianapolis 500. Starting in 2013, the race was hosted as a unique "doubleheader" weekend. The race weekend would consist of two separate, points-paying races, one each on Saturday and Sunday. The races were treated as separate events, with separate qualifying, full championship points, and the results of the first had no bearing on the lineup for the second (as had been the case with some previous "twin" race formats). Beginning in 2013, the race also returned to the more popular and more competitive "long" course (1998–2001 layout).^[27]

On April 6, 2020, IndyCar announced the cancellation of the 2020 edition due to the COVID-19 pandemic. Organizers stated that Michigan's stay-at-home order (which was extended through April 30)^[28] would hinder the necessary preparations to hold the race, and that the race could not be reasonably rescheduled due to other events having been booked on Belle Isle already. The race returned in its traditional double header format for 2021.^[29] On September 19, 2021, IndyCar announced that the Detroit Grand Prix would be altered from a two race weekend to a single race weekend as part of their 2022 schedule.^[30]

Downtown revival: 2023

Mere weeks after the 2022 IndyCar schedule was announced Penske Entertainment Group revealed that moving the Detroit Grand Prix to a single race weekend was done as part of a proposal discussed with the city of Detroit to return the race back to the Renaissance Center utilizing a new downtown circuit beginning in 2023. In November 2021, the City Council of Detroit unanimously approved Penske Entertainment's plan and announced an initial three-year contract to return the Detroit Grand Prix back to the downtown streets for a single race weekend beginning in 2023.^[31]

The new downtown circuit is based on lessons learned from the Nashville Street Circuit. It is designed to be less disruptive to city traffic while also being more accessible to spectators and having more points of visibility to the racing than the old Detroit Street Circuit. The new circuit will feature ten corners and is 1.7 miles in length compared to the 2.5 mile circuit used by Formula One and CART and the 2.35 mile Raceway On Belle Isle.^[32] It will travel from the start/finish line on Atwater Street and head onto Schwarzer Street, Franklin Street, and Rivard Street in the first series of corners. From Rivard Street drivers will make a sharp left turn onto the circuit's most prominent feature, a 0.7 mile straightaway down East Jefferson Avenue. This straightaway will be the longest straightaway on an IndyCar street circuit, eclipsing the dual straights on the Korean War Veterans Memorial Bridge in Nashville. The circuit will then turn onto Bates Street before heading back onto Atwater Street. The only part of the old Detroit Street Circuit used on the new circuit will be the old circuit's sixteenth and seventeenth corners that were then known as The Ford Corner. On the new circuit this section will be the eighth and ninth corners. Neither of the tunnels or the side streets used on the old Detroit Street Circuit will be used on the new circuit to minimize impact on local businesses and city traffic around downtown Detroit.^[33] To increase spectator viewership IndyCar and Penske Entertainment will offer free viewership at multiple points along the circuit.^[34] The Detroit City Council stated the entire circuit will be fully resurfaced before the race. Construction and tear down of the circuit will take place 8:00PM and 5:00AM over the course of twenty days respectively, minimizing disruptions to city traffic around the Renaissance Center.^[31]

Race summaries

CART PPG Indy Car World Series (Renaissance Center)

• 1989: Emerson Fittipaldi touched wheels with Mario Andretti on lap 2, puncturing a tire and sending him to the back of the field. But Fittipaldi charged from 27th position to second place in the closing laps. Polesitter Michael Andretti led 52 of the first 54 laps, but a radio wire became tangled in the throttle pedal. On lap 55, the throttle pedal stuck sending Andretti into a barrier. Scott Pruett was now leading the race by 17 seconds, but was forced to back off to conserve fuel. Fittipaldi blew by Pruett with four laps to go to take the victory.^[59][60]
• 1990: Michael Andretti started from the pole position and led wire-to-wire, winning the race in dominating fashion. Danny Sullivan was running close behind in second place on lap 46 when during his final pit stop, an impact wrench failed. The wheel was not properly fastened, and on the out-lap, the drive pegs on the wheel broke, putting him out of the race. Bobby Rahal nursing brakes, finished second, over one minute and 48 seconds behind Andretti. Rahal held off Emerson Fittipaldi who finished close behind in third.^[61]
• 1991: Emerson Fittipaldi, expecting the birth of his fifth child, was leading Bobby Rahal in the closing laps when gearbox problems arose. With seven laps to go, Fittipaldi's car kept jumping out of gear. He was mostly forced to hold the gearshift with one hand, and steer with only hand, on the rough, bumpy, demanding circuit. Rahal charged hard, but Fittipaldi held him off for the victory by 0.29 seconds. The race is best-remembered for a bizarre incident involving Mario and Michael Andretti. On lap 48, Dennis Vitolo stalled in turn four with a seized transmission. Safety crew tended to Vitolo's car, hooking up a tow rope. Mario Andretti came around what was a blind corner, locked up his brakes, and rammed hard into the back of the safety truck. The nose of the car was wedged underneath the truck's bumper, and the track was nearly blocked. A couple cars (including Fittipaldi) skirted by the scene, but seconds later, Michael Andretti slid and crashed into the back of Vitolo's car. The track was now completely blocked, and the red flag was put out to clean up the scene.^[62][63] This would be the final race held at the Renaissance Center circuit until 2023.

CART PPG Indy Car World Series (Belle Isle)

• 1992: For 1992, the race was moved to a new circuit on Belle Isle.^[10][11] Michael Andretti led the early laps, with Paul Tracy (subbing for Rick Mears) and Bobby Rahal close behind. Tracy made a daring pass on lap 38 for the lead going into turn one, nearly touching wheels with Andretti. On lap 58, Tracy was leading Andretti, with Bobby Rahal in third. All three cars were nose-to-tail. Andretti attempted to pass Tracy for the lead, but this time, the two cars touched. Both Tracy and Andretti slid high and scraped the concrete wall, allowing Bobby Rahal to slip by both to take the lead. Tracy later dropped out with gearbox failure, but Andretti stayed with Rahal, despite nursing an ill-handling machine. On the second-to-last lap, Andretti spun out and dropped to fourth while Rahal cruised to victory.^[64][65][66]
• 1993: A controversial race filled with penalties from start to finish. At the green flag,

• 2017 (Race 1): On Saturday, Graham Rahal led 55 of 70 laps to win, nearly 25 years to the day that his father Bobby won the race. Rahal held off second place Scott Dixon, who was driving despite an injured ankle from a major crash the week earlier at the Indianapolis 500.
• 2017 (Race 2): Graham Rahal swept the weekend, winning Sunday's second race, leading 41 of 70 laps.

  to stay in second place while Palou rounded out the podium.
• 2022: The final Detroit Grand Prix held on Belle Isle was moved from a double header to a single 70 lap race. Josef Newgarden qualified on pole but it would be his teammate Will Power who would dominate the race, charging through the field from 16th to take the lead early in the race and hanging onto it via virtue of a two stop strategy. Power's only threat on the day was Alexander Rossi, who picked up his first podium of 2022. Scott Dixon finished in third place.
