Detroit Grand Prix has been cancelled in 2020 due to the COVID-19 virus, affecting both the NTT IndyCar Series and the IMSA WeatherTech SportsCar Championship.
Both series were supposed to race in The Motor City the last weekend of May, but that event has officially been taken off both schedules.
IMSA states that they are working on a possible replacement later in the year, but there is nothing final just yet. There is about one month gap between Petit Le Mans and the final at Sebring, so they might be able to squeeze in an extra race between those two events, if they are able to find a suitable venue, with room in their schedule. The IMSA weekends are usually jam-packed with various support races, so it won’t be easy to double up on the WeatherTech SportsCar Championship races on the same weekend.
Indycar has already released an updated schedule, with the possibility of further changes.
The American single-seater series have chosen to do two races on the oval in Iowa, and the classic race circuit WeatherTech Raceway Laguna Seca. A third race weekend at Indianapolis Motor Speedway, run on the infield just like the July event, will also be added. This extra race will be on the first weekend of October.
That brings the Indycar schedule back to 15 races again, with St. Petersburg still being the final round but without a date yet.
The NTT IndyCar Series hopes to get their season underway on 6 June at the Texas oval, while the IMSA WeatherTech SportsCar Championship is planned to resume at Watkins Glen on 27 June. They have only done the Daytona 24 Hours so far this season.
