Detroit Victory Underscores Michelin Warm-Up Gains

Image
While strategy often defines IMSA’s 100-minute street races, Detroit provided a new chapter in the ongoing story of Michelin tire performance. For years, the conventional approach at races like Detroit and Long Beach has been to complete the race on a single set of tires. Instead, the No. 31 Whelen Engineering-sponsored Cadillac team with drivers Earl Bamber and Jack Aitken elected to change its right-side Michelin tires during the lone pit stop, taking advantage of an opportunity to maximize performance during the race’s multiple caution periods and restarts. “Yeah, we kind of flipped the script a little bit on that one because the conventional strategy for a long time at these 100-minute races has been to make a set last the whole way,” said Aitken. “And while they definitely can last the whole way, we thought we’ve got a little bit of margin. The warm-up was actually really good for just the one-sided tires. “So why not give ourselves the insurance...

Ariel Levi, Sebastian Ogaard and Rocco Mazzola delivered the first Audi win in the championship since Hockenheim 2022 aboard their No. 66 Audi R8 LMS Evo II, which also took honors in the Silver class, after a dramatic late accident meant the three-hour contest ended under caution. Kelvin van der Linde’s No. 32 WRT BMW M4 GT3 EVO, which had been leading with an hour to go, rear-ended the No. 9 Pure Rxcing Porsche 911 GT3 R Evo of Alexey Nesov, which was launched into a roll after ramming Ezequiel Perez Companc’s No. 25 Sainteloc Audi and then clattered into the luckless Marvin Dienst, whose No. 87 Winward Mercedes-AMG GT3 Evo had been on course for Bronze class spoils and second overall. This drama handed a runner-up finish to the No. 48 Winward Mercedes-AMG of Maro Engel, Luca Stolz and...

Aitken drove the No. 31 Cadillac V-Series.R to a 6.023-second win over the No. 25 Team WRT BMW M Hybrid V8 of Philipp Eng in the 100-minute race that saw two late-race yellow and restarts. The Whelen Engineering-sponsored Cadillac led from the start, thanks to an ideal getaway from pole-sitter Bamber, who stretched out into an early lead over the No. 93 Meyer Shank Racing Acura ARX-06 of Nick Yelloly, as the No. 40 Wayne Taylor Racing Cadillac of Louis Deletraz dropped back to fourth. A mid-race stop, where the No. 31 Cadillac took on fresh right-side Michelin tires, kept Aitken out front for the remainder of the contest. With the win, Aitken took over the GTP points lead, following a race to forget for the No. 5 JDC-Miller Motorspo...
