The Nürburgring 24 has been red-flagged after six hours of racing due to poor visibility in a dense fog around the German circuit.
Cars were ordered back to the pits when the clock hit 9:30 p.m. local time on Saturday, at the one-quarter distance milestone. An update at 10:30 p.m. declared that the earliest possible restart time is 7 a.m. (1 a.m. EST). The next update will be issued at 6 a.m.
Local Code 60 slow-zones were initiated at various parts of the 25 km Nordschleife combined circuit during the sixth hour. This later became a circuit-wide stoppage.
Haupt Racing Team’s No. 4 Mercedes-AMG GT3 Evo led at the red flag, with Adam Christodoulou at the wheel having taken over from Manuel Metzger at the car’s fifth stop.
Christodoulou, Metzger, Luca Stolz and Maro Engel – who is yet to drive HRT’s No. 4 Bilstein car – held an advantage of just under 40 seconds from the second-placed Schubert Motorsport BMW M6 GT3 with defending winner Alexander Sims at the wheel.
The Manthey Racing Porsche 911 GT3 R, which led early on through Kevin Estre before dropping behind HRT in the third hour, had slipped to fifth by the six-hour mark.
Matteo Cairoli was running 45 seconds off Christodoulou at the top of hour six, but the Italian ended up behind Sims, Phoenix Racing Audi driver Kim Luis Schramm and No. 98 ROWE Racing BMW driver Sheldon van der Linde after the fifth pit sequence.
Schramm’s No. 11 Audi R8 LMS GT3 Evo was right on the tail of Sims’ No. 20 BMW when the red flag was called.
The German driver had recently taken over from Nicki Thiim, who made a handful of overtakes to bring Audi’s top entry into contention for the podium positions.
Van der Linde was a further 16 seconds back in fourth, having fallen behind the Phoenix Audi around the time of the most recent pit stops, while Cairoli was 25 seconds away.
The pole-sitting No. 1 ROWE Racing BMW enjoyed a brief spell in the lead when HRT and Manthey pitted midway through the sixth hour, until Nick Yelloly brought the 2020-winning car in for its fifth scheduled stop that returned it to just outside the top five.
Dennis Olsen was running seventh in the No. 31 Frikadelli Racing Porsche, from Audi Sport Team Land’s Rene Rast and the two Mercedes-AMG Team GetSpeed entries.
A notable casualty between hours four and six was the Scuderia Cameron Glickenhaus 004C, which Richard Westbrook parked to one side on the GP circuit after spinning at Turn 1. The team stated on Twitter that the halt came after contact with another car.
Last year’s Nürburging 24 edition, which took place in late September rather than June, was put under an overnight flag after seven hours of racing due to heavy rain.
