Track map of The Raceway on Belle Isle

The 2021 Detroit SportsCar Classic was a sports car race sanctioned by the International Motor Sports Association (IMSA). The race was held at The Raceway on Belle Isle in Detroit, Michigan on June 12, 2021. This race was the fourth round of the 2021 IMSA SportsCar Championship, and the second round of the 2021 WeatherTech Sprint Cup.

Background

The Raceway on Belle Isle, where the race was held.

International Motor Sports Association's (IMSA) president John Doonan confirmed the race was part of the schedule for the 2021 IMSA SportsCar Championship (IMSA SCC) in September 2020. It was the seventh year the event was held as part of the WeatherTech SportsCar Championship, and the eleventh annual running of the race, counting the period between 2007 and 2013 when it was a round of the Rolex Sports Car Series and the American Le Mans Series respectively.[1] The 2021 Detroit Sports Car Classic was the fourth of twelve scheduled sports car races of 2021 by IMSA, the shortest in terms of time, and was the second round of the WeatherTech Sprint Cup.[2] The race was held at the fourteen-turn 2.350 mi (3.782 km) Belle Isle Park in Detroit, Michigan.[3]

Unlike its predecessors, the race was initially scheduled to be a standalone event, relinquishing its traditional joint weekend with the IndyCar Series in an attempt to avoid conflict with the 2021 24 Hours of Le Mans.[4] However, with the postponement of the Le Mans race to August, the race weekend was pushed back a week, allowing it to run in conjunction with the IndyCar double-header.[5] While the reschedule alleviated a conflict with the Nürburgring 24 Hours, it fell on the same weekend as the WEC race at Portimão, leading to a further conflict for WeatherTech Racing.[5] The classes competing at the event were also shuffled, as the LMP2 class was replaced with GTLM, which wouldn't score points towards the overall championship.[5] The DPi and GTD classes remained on the entry list from the initial date, with the latter still only scoring points towards the WeatherTech Sprint Cup.

The race also marked the first event since the dawn of the COVID-19 pandemic that fans would be allowed paddock access, in accordance with the lifting of outdoor venue gathering restrictions in the state of Michigan.[6]

Before the race, Filipe Albuquerque and Ricky Taylor led the DPi Drivers' Championship with 1070 points, ahead of Oliver Jarvis and Harry Tincknell in second with 1015 points.[7] Nicky Catsburg, Antonio García, and Jordan Taylor led the GTLM Drivers' Championship with 697 points, 41 points ahead of Cooper MacNeil.[7] With 920 points, the GTD Drivers' Championship was led by Bill Auberlen and Robby Foley.[7] Acura, Chevrolet, and BMW were leading their respective Manufacturers' Championships, while WTR-Konica Minolta Acura, Corvette Racing, and Turner Motorsport each led their own Teams' Championships.[7]

Entries

A total of 20 cars took part in the event, split across three classes. 6 cars were entered in DPi, 2 in GTLM, and 12 in GTD. Although no notable changes occurred in the DPi class, a handful of GTD competitors elected to forego the round due to its championship point output only counting for the WeatherTech Sprint Cup; namely Magnus Racing, Wright Motorsports, and Pfaff Motorsports. Buoying the GTD numbers, however, was SunEnergy1 Racing, who returned after skipping the Mid-Ohio round. In GTLM, the lone competitors were the two Corvettes, in line with WeatherTech Racing's expected absence.[8]

After the initial entry list was released, a pair of driver changes were made prior to the race weekend. Marco Mapelli joined Misha Goikhberg in the Grasser Racing Team entry,[9] while Townsend Bell subbed for Zach Veach, who missed the round after testing positive for COVID-19, in the Vasser Sullivan Racing No. 12.[10]

here were two practice sessions preceding the start of the race on Saturday, both on Friday. The first session lasted 90 minutes on Friday morning while the second session lasted 100 minutes on Friday afternoon.[11]

Qualifying

Kevin Magnussen (pictured in 2017) secured the overall pole position for Cadillac Chip Ganassi Racing.

Qualifying was broken into three sessions.[11] The first was for cars in the GTD class. Richard Heinstand qualified on pole for the class driving the No. 39 car for CarBahn Motorsports with Peregrine Racing, beating Frankie Montecalvo in the No. 12 Vasser Sullivan Racing entry by less than one-tenth of a second. Roman De Angelis was third fastest followed by Robby Foley in the No. 96 Turner Motorsport entry.[21]

The second session was for cars in the GTLM and GTD classes. Nick Tandy qualified on pole in GTLM driving the No. 4 car for Corvette Racing, besting teammate Jordan Taylor in the sister No. 3 Corvette Racing entry by more than three-tenths of a second.[22] Mario Farnbacher set the fastest time in the GTD points paying session and earned 35 WeatherTech Sprint Cup points. The No. 14 Vasser Sullivan Racing entry did not set a time after Aaron Telitz hit the wall at turn 2 in the first session.[21]

The final session of qualifying was for cars in the DPi class. Kevin Magnussen qualified on pole driving the No. 01 car for Cadillac Chip Ganassi Racing, beating Harry Tincknell in the No. 55 Mazda Motorsports entry by 0.021 seconds.[23] The session was shortened after Tristan Vautier, driving the No. 5 JDC-Mustang Sampling Racing Cadillac, crashed at turn 4. For causing a red flag, Vauiter had his best two laps from the session deleted.[22]

Race

Post-race

As a result of winning the race, van der Zande and Magnussen advanced from sixth to fourth in the DPi Drivers' Championship. Derani and Nasr jumped from fourth to third while Duval and Vautier dropped from third to fifth.[30] GTLM drivers, teams, and manufactures did not score full season points due to the event not counting for the overall championship.
