How to watch IMSA sports cars at Detroit: Schedule, TV info, streaming, start times, more

Hoping their "dream year" continues, Jonathan Diuguid and Raul Prados go back to their day jobs in the IMSA WeatherTech SportsCar Championship this weekend.

Diuguid, the managing director of Porsche Penske Motorsport, and Prados, an engineer on the No. 7 Porsche 963, worked as substitutes in May at Indianapolis Motor Speedway 500 after Roger Penske suspended four IndyCar team members because of the push to pass scandal from the season opener.

With Diuguid calling strategy and Prados on the timing stand for the No. 2 Dallara-Chevrolet, Josef Newgarden became the first back-to-back Indy 500 winner in 22 years.

It was the latest major triumph for Diuguid and Prado, who already had won the 2024 Rolex 24 at Daytona (with Newgarden as part of the four-driver lineup) as Newgarden won for the second consecutive year at IMS on a last-lap pass to take the lead.

Exclusive sitdown with Indy 500 winner Josef Newgarden: ‘Truthfulness is really important to me’

‘You can’t make a better Indy 500 than you got. That was a crazy duel.’

"I think this year is probably going to go down as a dream year," said Diuguid, who had been an IndyCar engineer for Penske with Helio Castroneves, Ryan Briscoe and Scott McLaughlin. "I feel a little bit guilty in the sense that I kind of showed up and everything was going smoothly, and I got the opportunity to be here. I think Josef said the same thing after the Daytona 24 Hours. He kind of rocked up and we got the first (Porsche) win after many, many decades.

"The details are what got it done (in the Indy 500). I was talking to Raul after the race, and I said, 'Raul, I don't think we made any mistakes today.' Might have made 50/50 decision one way or the other, but there was no mistakes, and that's what it takes to be in a position like we were at the end."

There will be another new challenge awaiting Saturday afternoon in downtown Detroit as IMSA makes its debut on the nine-turn, 1.7-mile layout that was introduced last year.

It'll be the first Detroit race for Porsche in the premier prototype category since 2008. Team Penske won the overall at the Belle Isle course in 2007 with a Porsche RS Spyder (a P2 car that beat the P1 class).

IMSA had raced at Belle Isle from 2007-22. The inaugural Chevrolet Detroit Sports Car Classic will be the second 100-minute sprint race on the 2024 schedule after Long Beach (which the No. 01 Cadillac of Chip Ganassi Racing won last month).
