Endurance racing and sprint action alike felt the effects of weather this past weekend, with the Nürburgring shrouded in fog and Road America interrupted by heavy storms. Still, Porsche, Mercedes-AMG, Ferrari, and Corvette all found their way to the top step.

Nürburgring Langstrecken-Serie – KW 6h ADAC Ruhr-Pokal-Rennen: Falken sweeps Nordschleife endurance

Falken Motorsports secured a dominant 1-2 in the fog-shortened six-hour classic, continuing Porsche’s unbeaten NLS run in 2025. After morning delays pushed qualifying back, Nico Menzel put the #4 Falken Porsche on pole, but it was the sister #3 machine of Klaus Bachler and Sven Müller that charged through to victory. Müller’s slipstream move on the Döttinger Höhe proved decisive, with the #3 car steadily edging clear to win by just over five seconds.

The #6 HRT Ford Mustang completed the podium with a clean run, while Black Falcon’s #48 Porsche claimed SP9 Pro-Am honours in fourth.

GT World Challenge America – Road America: Weather disruptions, late drama and a last-lap showdown

Race 1

Saturday’s opener was cut short by thunderstorms after a frantic start. Regulator Racing’s Mercedes-AMG of Philip Ellis and Jeff Burton was declared the winner, securing both overall and Pro-Am honours. Random Vandals Racing’s BMW took Pro class victory thanks to Kenton Koch’s decisive move before the weather rolled in, while AF Corse USA dominated Am with its Ferrari 296 GT3.

Ellis controlled the race from pole, quickly stretching a gap at the front before a pair of full-course cautions closed the field back up. Behind, Koch’s pressure on Michai Stephens set the tone for the Pro battle, while drama in Pro-Am saw the DXDT Corvette and Archangel McLaren hit trouble. But Ellis remained unchallenged at the head of the pack, leading until lightning forced officials to halt proceedings early, cementing Regulator Racing’s victory.

Race 2

Sunday produced a thriller right to the final lap. JMF Motorsports’ #34 Mercedes-AMG GT3 triumphed in Pro after Michai Stephens fended off Kenton Koch in the #99 Random Vandals BMW M4 GT3 during a tense restart dash. DXDT Racing struck back in Pro-Am as Blake McDonald, driving the #11 Corvette Z06 GT3.R, resisted immense pressure in the closing moments, while AF Corse USA’s #163 Ferrari 296 GT3 once again had the measure of Am, cruising to victory.

The final restart turned the race into a one-lap showdown, with Stephens defending aggressively from Koch into Turn 5 to hold the lead. Behind them, McDonald kept the Corvette ahead of Justin Rothberg’s #29 Turner Motorsport BMW M4 GT3 despite heavy late-race pressure, giving DXDT its long-awaited win. Further back, AF Corse’s Ferrari ran unchallenged to claim its second Am win of the weekend, underlining the team’s consistency.
