IndyCar Detroit Belle Isle doubleheader: How to watch, start times, live streaming info

Nate Ryan previews the top storylines prior to the weekend doubleheader, as the IndyCar Series returns to Detroit's Belle Isle.

After a two-year absence, the NTT IndyCar Series will return to Belle Isle Raceway in Detroit this weekend for a Saturday-Sunday doubleheader schedule of start times.

There are 25 entries for each race as Santino Ferrucci was added this week in a third car for Rahal Letterman Lanigan Racing after his sixth place in the Indy 500. Jimmie Johnson (No. 48 Dallara-Honda for Chip Ganassi Racing) and Romain Grosjean (No. 51 for Dale Coyne Racing) will return in Detroit after missing the Indianapolis 500.

After becoming the fourth driver to win his fourth Indy 500, Helio Castroneves won’t be racing at Detroit (but will be appearing in five more IndyCar races for Meyer Shank Racing this year and in the SRX this weekend). It’s the first time the Indy 500 winner isn’t entered in the following IndyCar race since the late Dan Wheldon in 2011.

The 2021 IndyCar season has opened with six winners in six races. There have been seven winners in the first seven races three times -- 1958, 2000, and ’17 (when the streak was broken by Graham Rahal sweeping Detroit). If there is no repeat winner in Saturday’s race, the record for most IndyCar winners to start a season will be tied.

Among those still seeking victories are former Detroit winners Josef Newgarden, Simon Pagenaud and Will Power of Team Penske.

Here are the details and IndyCar start times for the Chevrolet Detroit Grand Prix at Belle Isle Raceway in Detroit (all times are ET):
