Newly crowned Prototype champions Wayne Taylor Racing appear to be out of the Motul Petit Le Mans, following an apparent engine failure for the No. 10 Cadillac DPi-V.R in the third hour of the race.
Ryan Hunter-Reay brought the car into the pits with no power and fluids leaking from the rear of the V8-powered car.
The IndyCar star had been running in eighth at the time, just moments after climbing aboard the Konica Minolta-sponsored car after an opening double stint from Ricky Taylor.
“The guys in the back were watching the engine. The oil pressure went to zero,” Wayne Taylor told IMSA Radio.
The likely retirement comes less than three hours after clinching the championship, when Ricky Taylor took the green flag.
Up front, the pair of Tequila Patron ESM Nissan Onroak DPis continue to lead the way, with Bruno Senna ahead of Ryan Dalziel.
Antonio Garcia (Corvette Racing) and Connor De Phillippi (Land Motorsport) lead the production-based ranks with just over seven hours remaining.
