Vanthoor Tops Final Warm-Up as Penske Porsche Returns to Track

The short pre-race session showed slower race pace than qualifying, confirming Penske's rebuilt No. 6 Porsche had returned to action ahead of the 100-minute Detroit race.

Overview

Dries Vanthoor posted the fastest time in the 20-minute final practice with a 1:06.950 lap, a mark set on Saturday that led the field but remained about 1.5 seconds off pole pace.
Earl Bamber holds the race pole from qualifying after a record-setting lap, creating a clear benchmark that teams did not match in the warm-up.
Penske rebuilt the No. 6 Porsche overnight after Kevin Estre's qualifying crash and returned the car to track without fitting a replacement tub, the team completing repairs into the early hours.
Practice top-five in the final session consisted of Vanthoor (No. 24 BMW), Jordan Taylor (No. 40 Cadillac), Felipe Nasr (No. 7 Penske Porsche), Laurens Vanthoor (repaired No. 6 Penske Porsche), and Ricky Taylor (No. 10 Cadillac).
All 21 entered cars ran the warm-up without major incident and the Chevrolet Detroit Sports Car Classic is set to start at 4:10 p.m. EST with live coverage on NBC, Peacock and IMSA’s YouTube channel.
