2024 IMSA Battle on the Bricks
The 2024 IMSA Battle on the Bricks (officially known as the 2024 Tirerack.com Battle on the Bricks) was a sports car race held at Indianapolis Motor Speedway in Speedway, Indiana, on September 22, 2024. It was the tenth round of the 2024 IMSA SportsCar Championship, as well as the fourth round of the Michelin Endurance Cup.
Philipp Eng and Jesse Krohn secured BMW's and Team RLL first win in IMSA's SportsCar Championship since the 2023 Sahlen's Six Hours of The Glen after holding off late charges from the No. 6 Porsche Penske Motorsport car. It was Team RLL's first win with the BMW M Hybrid V8 where it actually took the chequered flag first. Connor De Phillippi and Nick Yelloly, driving the other RLL-fielded BMW, finished second, resulting in a historic first 1–2 finish for the M Hybrid V8 prototype. Mathieu Jaminet and Nick Tandy originally finished in third place, but were later stripped from their podium place as their car made use of non-homologated parts. Phil Hanson, Tijmen van der Helm, and Richard Westbrook inherited third place.

Qualifying
[edit]Saturday's afternoon qualifying session was broken into three sessions, with one session for the GTP, LMP2, GTD Pro and GTD classes, which lasted 15 minutes each. The rules dictated that all teams nominated a driver to qualify their cars, with the Pro-Am LMP2 class requiring a Bronze rated driver to qualify the car.[10] The competitors' fastest lap times determined the starting order. IMSA then arranged the grid to put GTPs ahead of the LMP2, GTD Pro, and GTD cars.[15]
