2021 Detroit Sports Car Classic
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.

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]
