Detroit Grand Prix

With the final numbers reported this week for the 30th Detroit Grand Prix, held May 31-June 2 at Belle Isle, the results suggest that the event continues to be a positive force for the local community and the region.

Grand Prix organizers estimated that this year’s summer celebration attracted 95,000 people to Belle Isle Park over the course of its three days. This included over 25,000 fans attending Comerica Bank Free Prix Day on Friday, May 31. Severe weather on Saturday, June 1 affected the attendance numbers as approximately 30,000 fans visited the Raceway at Belle Isle Park and on track action had to be postponed for a couple of hours with lightning accompanying the storm that surrounded the island. With sunny skies and cooler temperatures on Sunday, June 2, the Grand Prix attracted its largest Sunday attendance since 2014 with approximately 40,000 fans. With the turnout, it marked the seventh time in the last eight years that the Chevrolet Detroit Grand Prix reached the 95,000 mark in total attendance.


The Chevrolet Dual in Detroit NTT IndyCar Series doubleheader weekend delivered the highest total viewership numbers and the best combined Nielsen television rating in three years with the Saturday and Sunday race broadcasts on NBC. Dual II on Sunday, June 2 generated the top numbers for the weekend with nearly 1.2 million total viewers witnessing the action from Belle Isle. In the race won by reigning IndyCar Series champ Scott Dixon of Ganassi Racing, the total viewership grew by an impressive 17% from last year’s Sunday race in Detroit as the broadcast drew a .83 final Nielsen rating. Saturday’s Dual I also brought more total viewers, despite some significant weather challenges. Josef Newgarden of Team Penske, the 2017 series champion, won in a 75-minute timed race after the lightning delay on Belle Isle as the total viewership on NBC increased by 2% over 2018 with a final household rating of .70.

The two races combined to average a Total Audience Delivery (TAD) of 929,000 viewers across NBC, and the NBC Sports app – an increase of 10% from the TV-only viewership numbers in 2018 (846,000) on ABC. With the combined ratings of the two races, the Detroit weekend marked the second-highest rated NTT IndyCar Series event outside of the Indianapolis 500 so far this season.

Working with new local TV partner WDIV Local 4 (NBC affiliate station), the Friday, May 31 prime time (7-8 pm ET) broadcast from Belle Isle that included live coverage from the PwC Grand Prixmiere charity event drew a 4.4 household rating and was the top local show in its time slot. Both the Saturday and Sunday IndyCar race broadcast ratings in the Detroit market on WDIV-TV were up over 2018 with both telecasts ranking among the top four markets nationally, and Detroit was the second-highest rated TV market in the nation for Sunday’s Dual II NBC race broadcast.


The Grand Prixmiere gala raised approximately $800,000 for the Belle Isle Conservancy and targeted improvement projects on the island. Including this year’s total, the Grand Prixmiere has now generated over $4.8 million for the Belle Isle Conservancy over the last six years. A total of $200,000 from the funds raised at May 31st event will be utilized for long-term maintenance and operational work to keep the iconic James Scott Memorial Fountain operating on Belle Isle for years to come. More than $600,000 from the donations raised at the Grand Prixmiere over the last two years have been dedicated to projects at the fountain – which annually begins operating on Friday at the Grand Prix and runs throughout the summer on Belle Isle.
