What’s in store for the future of IMSA?
While we don’t have a magical crystal ball that will tell us, here’s a quick overview from IMSA President John Doonan.
Formula 1 wasn’t the only high-intensity racing at Circuit of the Americas this past weekend.

In September, we asked this, “Jimmy Rauck breaks Autobahn records. Is Pitt Race next?” The answer is a resounding yes.
Jimmy, in his turbocharged K20 Honda Civic, turned a 1:40.10 lap during last weekend's Gridlife event at Pittsburgh International Race Complex. That shattered the 1:44.366 mark set in Gridlife by Kyle McKiou in a Toyota Supra last year. The time even beat the 1:41.244 lap turned by Brian Faessler in a twin-turbocharged, 900-horsepower Ford Mustang during the 2025 Tire Rack Ultimate Track Car Challenge.
With Pitt Race set to close at the end of this year, that Gridlife track record is likely to stand forever.
What’s it like to set a blazing time like that? Jimmy shared in-car footage of his record run.

There’s never really a “good” time for your headlights to start malfunctioning, but “in the middle of the night during a 10-hour endurance race” has to be among the least ideal.
Yet that’s exactly what happened to the race-winning Cadillac V-Series.R in the closing laps of the 2024 IMSA Petit Le Mans.

What does it take to prepare and maintain several race cars competing in various series?
