IMSA has released the entry list for the Detroit Grand Prix this upcoming weekend. A total of 23 cars feature on the list, with 11 of them in DPi and 12 in GT Daytona.

LMP2 will skip this round as part of the series’ efforts to reduce the budget for the struggling class. GT Le Mans teams, meanwhile, will have their attention on preparations for the Le Mans 24. Specifically, the Le Mans Test Day, which is also set to take place this weekend.

There are two things of note in DPi, one of them being that Harry Tincknell will rejoin the Mazda Team Joest squad. Tincknell missed out on the Mid-Ohio round due to a scheduling conflict with the WEC and their Spa round where he ran with Ford.

Ryan Hunter-Reay filled in for Tincknell in the #55 Mazda RT-24P at Mid-Ohio, he and Jonathon Bomarito ended that race in third.

The second point of note in DPi is the empty seat in the #50 Juncos Racing Cadillac DPi-V.R has been filled. Will Owen was initially currently the only driver listed to drive the car, but his teammate has now been confirmed. It’s not Kyle Kaiser, who filled the seat at Mid-Ohio and Long Beach, instead, it’s Victor Franzoni.

Franzoni is currently running in Indy Lights with Juncos. The race at Detroit will be his first start in the top rung of the IMSA WeatherTech series.

“I’m super excited to be back with Juncos Racing and be a part of their Cadillac DPi-V.R programme,” Franzoni said.

“I’ve been racing with the team for a few years now, we have built a great chemistry and produced great results. I am looking forward to working with Will Owen since he has a lot of experience with this type of car, and this will be my first time in this type of car. We will work hard and look for a great result in Detroit.”

The Le Mans test weekend has also claimed one entry from the GTD class, that being the #33 Riley Motorsports Mercedes-AMG GT3. Drivers, Ben Keating and Jeroen Bleekemolen will be preoccupied in France as they, along with Felipe Fraga, prepare to be the first customer crew to run the Ford GT in the GTE Am class.

Other notable entries include the #57 Heinricher Racing with Meyer Shank Racing Acura NSX GT3 of Katherine Legge and Christina Nielsen. The entry of the #57 Acura comes as a part of the IMSA Sprint Cup mini-championship.

“I really love the track. It’s a cool circuit with lots of close racing, but it’s also an event that is always well executed and gives back to the community.” Said Nielsen. “I had three podiums in 2015-2017 so I hope to add another one to the books. The team has been really impressive there the last couple of years so I feel like I am in good hands.”

Also continuing its commitment to the Sprint Cup is Compass Racing and its #76 McLaren 720S GT3 of Paul Holton and Matt Plumb, which made its IMSA debut at Mid-Ohio.

IMSA will be sharing the Detroit street-circuit with IndyCar this weekend with the race set for Saturday, June 1 at 12:30 PM EDT or 16:30 GMT.
