22-car IMSA field set for Detroit

IMSA has published the entry list for the upcoming Chevrolet Sports Car Classic at the Detroit Renaissance Center street circuit, which takes place next Saturday, May 31 as the WeatherTech SportsCar Championship joins IndyCar on the Detroit Grand Prix weekend. The 11 full-season GTP cars are joined by the 10 full-season entries from GTD PRO, plus one additional entry from Vasser Sullivan Racing.

Vasser Sullivan has once again opted to enter its two Lexus RC F GT3s in the same GT category as it did at Long Beach. Aaron Telitz will continue to drive the No. 14 Lexus, now joined by Jack Hawksworth, who is back in the No. 14 car taking the place of a still-healing Ben Barnicoat. And with the GTD class out of action, Parker Thompson will get to drive in GTD PRO, in the renumbered No. 15 Lexus alongside Frankie Montecalvo.

After four races, Porsche Penske Motorsport leads all major GTP championship standings and will once again put its undefeated streak in the WeatherTech Championship on the line. The No. 7 Porsche 963 of Felipe Nasr and Nick Tandy leads the drivers' and teams' standings by 91 points over the No. 6 Porsche of Mathieu Jaminet and Matt Campbell, which took its first win at Laguna Seca last week.

BMW M Team RLL's two challengers sit a distant third and fourth in the GTP standings: The No. 24 BMW M Hybrid V8 of Dries Vanthoor and Philipp Eng trails Nasr/Tandy by 280 points, and the No. 25 of Marco Wittmann and Sheldon van der Linde is 353 points out. Cadillac Whelen's Jack Aitken sits fifth in the drivers' standings, ahead of Acura Meyer Shank Racing's Renger van der Zande and Nick Yelloly in sixth.

But it's Ricky Taylor and Filipe Albuquerque who enter as the defending winners, the first around the narrow GM RenCen street course. The drivers of the No. 10 Cadillac V-Series.R will look to get their first win of 2025 and turn around what has been a frustrating season for Wayne Taylor Racing.

Porsche leads the GTP manufacturers' standings by 164 points over BMW, with Cadillac in third and Acura in fourth.

Meanwhile, the most recent race at WeatherTech Raceway Laguna Seca has shaken up the GTD PRO standings. After taking their second win of the season in the No. 77 AO Racing Porsche 911 GT3 R, Laurin Heinrich and Klaus Bachler have moved up to the lead in the drivers' standings.

It was also confirmed today that AO Racing will bring back the "Roxy" livery after "Rexy's" sister finally took her first IMSA win at Laguna Seca. AO Racing also won last year in Detroit.

Heinrich and Bachler have a 70-point lead over Corvette Racing/Pratt Miller Motorsports' Antonio Garcia and Alexander Sims who sit second in the table. With his strong run at Laguna Seca, Albert Costa of DragonSpeed has moved up to third in the standings, 75 points behind, while a tough race has dropped Ford Multimatic Motorsports' Christopher Mies and Frederic Vervisch down to fourth in the table, 107 points out of the top spot.

Porsche leads the GTD PRO manufacturers' standings by 62 points, but BMW, Ferrari, Chevrolet, and Ford are only separated by 20 points in their battle for second.
