IMSA debutant Kevin Magnussen has set the fastest time in night practice at the Roar Before the 24.
The former Formula One racer posted the quickest time in his #01 Chip Ganassi Racing Cadillac DPi-VR as his best effort of 01:35.412 knocked Whelen Engineering’s Mike Conway off the top spot.
Conway ended the session 0.040s slower down in second place in the #31 Cadillac DPi-VR, while Toyota WEC team-mate Kamui Kobayashi sweeped the top three in the #48 Ally Cadillac Racing Cadillac.
This also means that Cadillac runners have led the way in each of the Roar practice session, with the sole exception of Saturday’s qualifying session. In that session, Mazda was promoted to pole after Whelen Engineering failed post-qualifying scrutineering.
In LMP2, a late flyer from Nicolas Lapierre put the #52 PR1/Mathiasen Motorsports ORECA 07-Gibson up top. The Frenchman’s 01:37.099 was enough to beat Antonio Fuoco and the #47 Cetilar Racing Dallara P217-Gibson to the top spot.
Ben Hanley was third in the #81 DragonSpeed ORECA, followed by Tower Motorsport’s Gabriel Aubry as the top four in class were covered by just 0.174s.
The top five was rounded out by Job van Uitert and Racing Team Nederland.
Riley Motorsports led the way one-two in LMP3, as the #74 Ligier JS P320 of Oliver Askew set a 01:43:442 ahead of the #91 sister car in the hands of Jeroen Bleekemolen.
Wayne Boyd took the #33 Sean Creech Motorsport Ligier to third, with Matt McMurry fourth for CORE Autosport.
Corvette Racing returned to the top of the time sheets in GTLM, with Nick Tandy setting the pace in the #4 Corvette C8.R. The Briton turned a best lap of 01:43.615, enough to beat out the #24 BMW M8 GTE of John Edwards by 0.237s.
Antonio Garcia was third in the #3 Corvette, ahead of Philipp Eng’s #24 BMW and Gianmaria Bruni in the #79 WeatherTech Racing Porsche 911 RSR-19.
Finally, GTD was led by the #63 Scuderia Corse Ferrari 488 GT3 Evo of Marcos Gomes, ahead of Mirko Bortolotti and Luca Stolz for GRT Grasser Racing Team and SunEnergy1 Racing respectively.
