DAYTONA BEACH, Fla. – With six hours remaining in the Rolex 24 at Daytona, Wayne Taylor Racing’s No. 10 Cadillac DPi-V.R sits firmly in command at the head of the overall order.

Ryan Briscoe led the way as the clock ticked past the 18-hour mark on Sunday morning, despite an unscheduled pit stop just four laps into his stint that dropped his leading margin from more than a minute over the JDC-Miller Motorsports No. 5 down to just 17 seconds.

Briscoe took over the reins of the No. 10 from Renger van der Zande at the WTR team’s most recent driver change, while Loic Duval sat second as the only other lead-lap car.

The Mazda pair of Tristan Nunez and Ryan Hunter-Reay sits third and fourth, respectively, at the three-quarter distance mark. The No. 77 is one lap down, with the No. 55 two laps in arrears.

Henrik Hedman leads the LMP2 class for Dragonspeed in the No. 81 ORECA 07 after PR1/Mathiasen Motorsports had to bring the No. 52 down for lengthy pit service at the end of the 18th hour.

That put Ben Keating three laps down to the class-leading entry of Hedman, with Kyle Tilley on the provisional podium for Era Motorsport in the No. 18.

GT Le Mans continued to be led by the pair of Porsche Motorsport 911 RSRs, with the No. 912 entry piloted by Earl Bamber heading the No. 911 steered by Nick Tandy by 13.945 seconds.

Third was the No. 3 Corvette C8.R of Jordan Taylor, while the No. 24 BMW M8 GTE of Augusto Farfus also remained on the lead lap with six hours remaining.

Madison Snow headed the GT Daytona class in the No. 48 Lamborghini Huracan GT3, with Mirko Bortolotti eight seconds behind in the No. 88 WRT Speedstar Audi R8 LMS GT3  Evo.

Andy Lally was third in the GRT Magnus Lamborghini.

The race set a record just before the 18th hour for the longest green-flag stint in Rolex 24 history, having resumed at lap 356 and remaining under full-speed conditions from that point.

With six hours to run, leader Briscoe had completed 630 laps of the 3.564-mile Daytona Int’l Speedway road course, for a race distance of 2,245.32 miles through 18 hours.
