IMSA Sebring Hour 4: Cadillacs run 1-2-3-4
At the 1/3 mark of the 12 Hours of Sebring, the #31 Whelen Engineering Cadillac was leading by 2.325 s over the #48 Ganassi Cadillac, the #5 Mustang Sampling Cadillac and the 302 Ganassi Cadillac.
Four hours into Saturday’s race, Conway had the No. 31 Whelen Engineering Racing Cadillac DPi-V.R in the overall and Daytona Prototype international (DPi) class lead in the historic endurance race at Sebring International Raceway.
Conway, who co-drives the Action Express Racing car with Pipo Derani and Tristan Nunez, honored his dad, Michael Conway, who passed away on Friday, with an Instagram post and message.
“Today we lost a great man who will be sorely missed by many but more so by me and my family,” Conway wrote. “Really is a tough day for everyone who knew him, but I’ll always remember all the racing we did together and all the hours in the garage tinkering with cars. Mostly dad fixing all the things I broke but I learned a lot from this man, and I miss you so much, Pops. Rest in peace, love you.”
The class leaders four hours into the race were Conway in DPi, Giedo van der Garde in the No. 29 Racing Team Nederland ORECA LMP2 07 in Le Mans Prototype (LMP2), Dakota Dickerson in the No. 30 Jr III Racing Ligier JS P320 in Le Mans Prototype 3 (LMP3), Jordan Taylor in the No. 3 Corvette Racing Corvette C8.R GTD in GTD PRO and Michael de Quesada in the No. 28 Alegra Motorsports Mercedes-AMG GT3 in GT Daytona (GTD).
